+All changes by Paul Macklin unless otherwise noted.
+
+*--------------------------------------------------------------------*
+
+Version: 0.50
+ Date: 1-31-2005
+
+ None! (first release)
+
+*--------------------------------------------------------------------*
+
+Version: 0.51
+ Date: 2-14-2005
+
+ Added full 32-bit BMP file support
+
+ Took out annoying "colors: " message from BMP8 initialization
+ from scratch
+
+ Added more license and copyright info to each file
+
+ Added change log to library
+
+ To do next:
+ Should update the error messages for the initializations
+ Should simplify the reading and writing code
+
+*--------------------------------------------------------------------*
+
+Version: 0.52
+ Date: 2-19-2005
+
+ Fixed a minor bug in the MakeGreyscalePalette function where the
+ 0 color turned out to be (255,255,255), rather than (0,0,0)
+
+ Updated standard colors for 4-bit, 8-bit, and 24-bit
+
+*--------------------------------------------------------------------*
+
+Version: 0.53
+ Date: 2-27-2005
+
+ Fixed unsigned / signed problem that VS.net shows
+
+
+ Tried fix of line 186 in EasyBMP_BMP4.h file. If it works,
+ I'll apply it consistently. I think that VS.net wants us
+ to clear char* blah, then char = new blah [size], just
+ like the old days for g++.
+
+ Removed EasyBMP_StandardColors.h from standard package
+
+*--------------------------------------------------------------------*
+
+Version: 0.54
+ Date: 2-27-2005
+
+ The fix of line 186 in EasyBMP_BMP4.h file appears to have
+ worked. I applied it through the remainder of the code.
+ Hopefully, this should ensure Visual Studio.Net compati-
+ bility.
+
+ Fixed some typos in the comment lines
+
+*--------------------------------------------------------------------*
+
+Version: 0.55
+ Date: 5-2-2005
+
+ Introduced RGBApixel struct.
+
+ Introduced BMFH, BMIH, and BMP classes.
+
+ Deprecated all old code to *_legacy.h.
+
+ Rewrote EasyBMP_VariousBMPutilities.h to use the new
+ BMP class.
+
+*--------------------------------------------------------------------*
+
+Version: 0.56
+ Date: 5-4-2005
+
+ Made Width, Height, and BitDepth private members and added
+ functions for accessing them.
+
+ Made a new function, SetBitDepth, as the only means to
+ change the bit depth. It will create/resize a palette as
+ necessary. This simplifies the WriteToFile code, as well as
+ any palette altering algorithms. (All algorithms can now
+ assume that a properly-sized palette exists.) This will
+ help improve code stability greatly.
+
+ Made a new function, SetSize, as the only way to change the
+ width and height of the image.
+
+ Eliminated useless HasPalette and NumberOfColors members,
+ and added TellNumberOfColors() function.
+
+ Updated EasyBMP_VariousBMPutilities.h to respect privacy
+ of data members.
+
+*--------------------------------------------------------------------*
+
+Version: 0.57
+ Date: 5-8-2005
+
+ Removed fclose(fp) lines from EasyBMP_BMP.h and
+ EasyBMP_VariousBMPutilities.h whenever ( !fp ) occurs,
+ to avoid a crash when trying to close a non-existant file.
+
+
+ Added a line to set bmfh.bfType = 0; to getBMFH() routine
+ in the case where ( !fp ) occurs, so that a nonexistant file
+ doesn't falsely show up as a bitmap file.
+
+ Made error messages in BMP::ReadFromFile(char*) more meaningful,
+ since Argh! doesn't help much. :-)
+
+ Made ReadFromFile operations safer: can deal more effectively
+ with corrupted and/or truncated files by adding the new
+ SafeFread() wrapper function.
+
+ Moved all change-log entries to the change log to make the source
+ file tidier.
+
+ Removed all references to Palettes; renamed them to ColorTables.
+
+*--------------------------------------------------------------------*
+
+Version: 0.58
+ Date: 5-13-2005
+
+ Rewrote ReadFromFile() to fix program crashes on reading 4-bit
+ files. (*grumble* I can't believe there was such a bug in such
+ a late version! */grumble*)
+
+ Added support to ReadFromFile() for reading 1-bit files.
+
+ Rewrote ReadFromFile() to avoid trying to read bitmap files of
+ depths other than 1, 4, 8, 24, and 32 bits.
+
+ Tested reading 4-bit files of width 0,1,2, and 3 (modulo 4),
+ and 1-bit files of width 0,1,2,3,4,5,6, and 7 (modulo 8)
+
+*--------------------------------------------------------------------*
+
+Version: 0.59
+ Date: 5-15-2005
+
+ Made ReadFromFile() more robust. Evidently, reading to the
+ same temp variable all the time made it unstable when reading
+ many files. I would never have guessed. I instead declare BMIH
+ and BMFH objects and read directly to their members. This appears
+ to be more stable when dealing with many ReadFromFile() calls.
+
+ On a related note, made sure to not call SetSize( Width,Height),
+ which is a bit recursive, as well as SetBitDepth( BitDepth ).
+ This appears to help stability, since these two functions were
+ create precisely for the purpose of setting those variables
+ values safely.
+
+ Made use of the boolean return value in SafeFread() to detect
+ when files are obviously corrupted. Used this to have an early
+ catch in ReadFromFile() and set it to a 1x1 1-bit image and
+ exit.
+
+ Made ReadFromFile() stricter, in that it only reads recognized
+ bit depths (1,4,8,24,32). Any other bit depth will prompt the
+ routine to terminate and set it to a 1x1 1-bit file.
+
+ Added write support for 1-bit files.
+
+ Rewrote WriteToFile() for 4,8-bit files to match methods used
+ for reading them.
+
+ Revised CreateStandardColorTable() and
+ CreateGreyscaleColorTable() to add support for 1-bit files.
+
+ Rewrote WriteToFile() to be stricter in only writing known bit
+ depths (1,4,8,24,32) and ignoring all others.
+
+*--------------------------------------------------------------------*
+
+Version: 0.60
+ Date: 5-21-2005
+
+ Deprecated *_legacy.h files.
+
+ Tested library extensivey in linux with good results.
+
+ Made CreateGreyscaleColorTable() stricter, in that it exits
+ if supplied a bit depth other than 1, 4, or 8.
+
+ Made cosmetic changes in EasyBMP_DataStructures.h to
+ improve readability.
+
+ Made SetBitDepth() stricter, in that it will never allow a bitmap
+ to be set to an unsupported bit depth. Only bit depths of 1, 4,
+ 8, 24, or 32 are accepted.
+
+ Made SetSize() stricter, in that it will not allow negative
+ widths or heights.
+
+ Made cosmetic changes in EasyBMP_BMP.h to improve readability.
+
+ Added a check in ReadFromFile() to see if the requested width or
+ height is negative, a good sign of file corruption. In such a
+ case, the file is set to a blank 1x1 1-bit file.
+
+ Added code to ReadFromFile() to set size to 1x1 and bit depth to
+ 1-bit if the file was not found.
+
+*--------------------------------------------------------------------*
+
+Version: 0.61
+ Date: 5-22-2005
+
+ Fixed awIndex typo in WriteToFile().
+
+ Replaced double BestDistance comparisons in WriteToFile()
+ with int BestDistances (so as to do integer operations,
+ rather than double operations). This gave a roughly 100%
+ speedup in 8-bit, 4-bit, and 1-bit write operations on
+ unoptimized (no compiler flags) code and a 30% speedup
+ on optimized code.
+
+ Removed checks like if( BestDistance < 1 ){ k=256; } .. from
+ WriteToFile(), as they give more overhead than savings in my
+ testing. For 8-bit files, there was a slight gain by putting
+ it back in with another method:
+ while( k < 256 && BestDistance > 0 ).
+
+ Redefined StepSize in CreateGreyscaleColorTable() to give a
+ better range of greys in 4-bit mode. As it was, white was not
+ in the color table. (Colors were spaced by 256/16 = 16). Now,
+ colors are spaced by (255-1)/(16-1) = 17, which gives the full
+ range.
+
+*--------------------------------------------------------------------*
+
+Version: 0.62
+ Date: 5-25-2005
+
+ Added endianess check function IsBigEndian() to
+ EasyBMP_DataStructures.h file.
+
+ Added functions to swap bytes in WORD and DWORD multibyte
+ variables to EasyBMP_DataStructures.h file for future big-endian
+ support.
+
+ Added functions to switch endianess to BMFH and BMIH objects
+ to EasyBMP_DataStructures.h file.
+
+ Added endianess checks to ReadFromFile() and WriteToFile()
+ functions in EasyBMP_BMP.h file, along with endianess conversions
+ where necessary.
+
+ Added endianess checks and conversions to GetBMFH() and GetBMIH()
+ functions in EasyBMP_VariousBMPutilities.h file.
+
+ Rewrote GetBitmapInfo() function to use GetBMFH() and GetBMIH()
+ functions instead. (In EasyBMP_VariousBMPutilities.h.) This
+ cuts down on the redundancy in the code.
+
+ Renamed GetBitmapInfo() to DisplayBitmapInfo() in the
+ EasyBMP_VariousBMPutilities.h file.
+
+ With these changes, big-endian architectures should be supported,
+ including IBM PowerPC, Sun Sparc, Motorola 86k, etc., and
+ including Mac OSX.
+
+*--------------------------------------------------------------------*
+
+Version: 0.63
+ Date: 7-20-2005
+
+ Added IntPow(int,int) function to help compiling with std
+ namespace. Besides, integer operations are faster and more
+ accurate.
+
+ Moved Square(double), IntSquare(int), and IntPow(int,int) to
+ EasyBMP_DataStructures.h
+
+ Simplified and cleaned up code in
+ Create4bitColorTable( RGBApixel**).
+
+ Changed safety check in BMP.ReadFromFile(char*) to set size to
+ 1 x 1 if width or height is non-positive, rather than simply
+ negative.
+
+ Added bounds checking to BMP.operator()(int,int) to automatically
+ truncate requested pixel if out of bounds. Also added a warning
+ to cue the user in. :-)
+
+ Made error messages more consistent in format.
+
+ Simplified and cleaned up code in
+ Create4bitColorTable( RGBApixel**).
+
+ Added #include <iostream.h> to EasyBMP.h, since EasyBMP uses
+ cout, etc.
+
+ Simplified and cleaned up code in
+ Create1bitColorTable( RGBApixel**).
+
+ Changed BMP.SetSize(int,int) to disallow non-positive widths and
+ heights, rather than simply negative widths and heights. Such
+ function calls are now ignored.
+
+*--------------------------------------------------------------------*
+
+Version: 0.64
+ Date: 8-2-2005
+
+ Changed "include <iostream.h>" to "include <iostream>" for
+ ANSI-C++ compliance, as well as for better compatibility with the
+ std namespace and VC++. (Thanks, Tommy Li!)
+
+ Added some #ifndef pragmas to each header so that it should be
+ fine to incluce EasyBMP.h in multiple files in larger projects.
+
+ Added "using namespace std" inside any function that used C++
+ math or I/O operations. I avoided putting "using namespace std"
+ anywhere with global scope for maximum compatibility with C++
+ software in the wild.
+
+ Added includes for <cmath> and <cstdio> to EasyBMP.h
+
+ Removed unused temporary variables (TempWORD and TempDWORD) from
+ EasyBMP_BMP.h for cleaner compiling. If I see any more such
+ unused variables, I'll remove them, too.
+
+*--------------------------------------------------------------------*
+
+Version: 0.65
+ Date: 8-13-2005
+
+ Moved implementations of BMP::BMP(), BMP::~BMP(), and
+ BMP::operator()(int,int) outside of the class. This should help
+ for eventually moving everything into a separate cpp file.
+
+ Made RGBApixel** Pixels a private data member of the class
+ BMP.
+
+ Added function void BMP::SetColor(int,RGBApixel) to BMP class
+ to allow safe method of changing a color in the color table.
+
+ Added function RGBApixel BMP::GetColor(int) to BMP class
+ to allow safe method of retrieving a color in the color
+ table.
+
+ Cleaned up error messages in EasyBMP_BMP.h
+
+ Cleaned up error messages in EasyBMP_VariousBMPutilities.h
+
+*--------------------------------------------------------------------*
+
+Version: 0.66
+ Date: 8-18-2005
+
+ EasyBMP_StandardColorTables.h was removed from the library.
+
+ CreateStandardColorTable(RGBApixel**,int) was changed to
+ CreateStandardColorTable() and made a member function of BMP.
+ All other CreateStandardColorTable functions are now unnecessary
+ and have been removed.
+
+ CreateGreyscaleColorTable(RGBApixel**,int) was changed to
+ CreateStandardColorTable( BMP& ) and moved to
+ EasyBMP_VariousBMPutilities.h.
+
+ RGBApixel* Colors was made a private data member of the BMP
+ class.
+
+ CreateGreyscaleColorTable( BMP& ) was renamed to
+ CreateGrayscaleColorTable( BMP& ).
+
+*--------------------------------------------------------------------*
+
+Version: 0.67
+ Date: 9-14-2005
+
+ Made the EasyBMP custom math functions in
+ EasyBMP_DataStructures.h inline. (Square,IntSquare,IntPow).
+ This should make those function calls faster while improving
+ compatibility with compiling DLL's.
+
+ Separated the code from SafeFread() in EasyBMP_BMP.h to
+ improve compatibility with compiling DLL's.
+
+ Removed #define _WINGDI_H from EasyBMP_DataStructures.h to
+ improve compatibility with win32 applications. Instead,
+ there's an extra #ifndef _SELF_DEFINED_BMP_DATA_TYPES
+ conditional added.
+
+ _SELF_DEFINED_BMP_DATA_TYPES renamed to _SELF_DEFINED_WINGDI
+ in EasyBMP_DataStructures.h.
+
+ All bit-flipping functions (IsBigEndian, FlipWORD,
+ FlipDWORD) in EasyBMP_DataStructures.h were made inline
+ to improve execution speed and improve compatibility with
+ compiling DLL's.
+
+ All code was separated from function declarations in
+ EasyBMP_VariousBMPutilities.h to improve compatibility
+ with compiling DLL's.
+
+ Updated and cleaned up layout of EasyBMP_ChangeLog.txt.
+
+ Updated contact and support information in library files.
+
+ Corrected the LGPL license version.
+
+*--------------------------------------------------------------------*
+
+Version: 0.68
+ Date: 10-9-2005
+
+ Changed references to FILE to std::FILE in the SafeFread function
+ in EasyBMP_BMP.h to improve compatibility with Borland's compiler.
+
+ Removed a few assignments in EasyBMP_BMP.h that weren't used to
+ improve efficiency and reduce Borland warnings.
+
+ Changed calls like NotCorrupted = SafeFread() to
+ NotCorrupted &= SafeFread() in BMP::ReadFromFile() in EasyBMP_BMP.h
+ to improve robustness. Now, if the NotCorrupted bit is ever set
+ to false, it stays false, meaning that the function won't "forget"
+ that it encountered file corruption.
+
+*--------------------------------------------------------------------*
+
+Version: 0.69
+ Date: 10-19-2005
+
+ Changed BMP::WriteToFile( char* ) to BMP::WriteToFile(const char*)
+ in EasyBMP_BMP.h to respond to a feature request.
+
+ Changed BMP::ReadFromFile( char* ) to BMP::ReadToFile(const char*)
+ in EasyBMP_BMP.h to respond to a feature request.
+
+ Made BMP::ReadFromFile() and BMP::WriteToFile() in EasyBMP_BMP.h
+ return true/false to indicate success/failure in the operations.
+ These functions previously returned void.
+
+ Made BMP::SetSize() and BMP::SetBitDepth() in EasyBMP_BMP.h
+ return true/false to indicate success/failure in the operations.
+ These functions previously returned void.
+
+ Made BMP::SetColor() and BMP::CreateStandardColorTable() in
+ EasyBMP_BMP.h return true/false to indicate success/failure in the
+ operations. These functions previously returned void.
+
+ Made CreateGrayscaleColorTable() in EasyBMP_VariousBMPutilities.h
+ return true/false to indicate success/failure in the operations.
+ This function previously returned void.
+
+ Changed the char* argument GetBMFH( char* ), GetBMIH( char* ),
+ DisplayBitmapInfo( char* ), and GetBitmapColorDepth( char* ) in
+ EasyBMP_VariousBMPutilities.h to const char* for cleaner, safer
+ programming.
+
+*--------------------------------------------------------------------*
+
+Version: 0.70
+ Date: 10-19-2005
+
+ Found and fixed error in BMP::ReadFromFile() in the check for only
+ reading support bit depths.
+
+ Changed license from LGPL to BSD (revised/modified) to simplify
+ licensing issues and resolve any lingering licensing questions.
+
+ Fixed compiler error when using MSVC++.
+
+ Improved fix to allow compiling with Borland without breaking
+ Borland support.
+
+ Added a few lines to EasyBMP.h to make it easier to tailor code
+ to specific compilers. (For future use as needed.)
+
+ Added a few lines to EasyBMP_BMP.h (in BMP::ReadFromFile(),
+ BMP::WriteToFile(), and BMP::SetBitDepth()) to eventually add
+ support for 16-bit files.
+
+*--------------------------------------------------------------------*
+
+Version: 0.71
+ Date: 11-01-2005
+
+ Cleaned up comments in BMP::ReadFromFile() in EasyBMP_BMP.h
+
+ Added endian-safe read support for 16-bit files that are in the
+ standard 5-5-5 format (not specified in bit fields)
+
+ Added endian-safe read support for 16-bit files that use bit
+ fields, including 5-6-5 files.
+
+ Added endian-safe write support for 16-bit files. Uses the 5-6-5
+ encoding scheme to maximize the utility of the bits used.
+
+ Added a check for compression in BMP::ReadFromFile(). Because
+ file compression is beyond the scope of EasyBMP, such files are
+ not supported, and EasyBMP now properly detects these situations
+ and exits with an error.
+
+ Added a check for files that attempt to use bit fields but are not
+ 16-bit files to BMP::ReadFromFile(). Such files are not supported.
+
+ Added a check to BMP::ReadFromFile() for files that use unknown
+ values of bmih.biCompression, such as old OS2 bitmaps. Such files
+ are not supported.
+
+ Removed "switching endianness" messages from EasyBMP_BMP.h
+
+ Added support for indexed (1, 4, and 8-bit) files that don't
+ specify all the colors.
+
+ Added support for reading files that include extra meta data before
+ the pixels. This data is skipped.
+
+ Added enclosing #ifndef EasyBMP ... lines to EasyBMP.h as a
+ further safeguard when EasyBMP is included in multiple cpp
+ files.
+
+*--------------------------------------------------------------------*
+
+Version: 1.00
+ Date: 02-06-2006
+
+ First Production/Stable release.
+
+ Corrected typographical errors in the comment sections of all
+ files.
+
+ Updated copyright on all files.
+
+ Removed extraneous comment in BMIH::BMIH() function in
+ EasyBMP_DataStructures.h file.
+
+ Replaced instances of \n with the more modern endl in
+ EasyBMP_DataStructures.h, EasyBMP_BMP.h, and
+ EasyBMP_VariousBMPutilities.h.
+
+ Added placeholder MetaData1 and MetaData2 data members to the
+ BMP class for potential future use.
+
+ Removed extraneous comments from EasyBMP_BMP.h.
+
+ Removed warning messages for switching endianness from
+ EasyBMP_VariousBMPutilities.h.
+
+ Updated copyright in EasyBMP_ChangeLog.txt file.
+
+ Fixed formatting issues in EasyBMP_ChangeLog.txt file.
+
+ Added DefaultXpelsPerMeter and DefaultYpelsPerMeter in
+ EasyBMP.h. These will default to 96 dpi.
+
+ Changed BMP::WriteToFile() to use DefaultXpelsPerMeter and
+ DefaultYpelsPerMeter when writing the BMIH structure.
+
+ Added XpelsPerMeter and YpelsPerMeter data members to BMP
+ class so that horizontal and vertical resolution are handled
+ properly. Currently, upon reading a file, the stated resolutions
+ are preserved, and upon writing, if no resolutions are given,
+ the defaults (of 96 DPI) are used.
+
+ Added function void BMP::SetDPI(int,int) to set the horizontal
+ and vertical resolutions.
+
+ Removed some unnecessary code from GetBitmapColorDepth() in
+ EasyBMP_VariousBMPutilities.h.
+
+ Fixed a bug in RangedPixelToPixelCopyTransparent() and
+ RangedPixelToPixelCopy() in EasyBMP_VariousBMPutilities.h which
+ caused copies to be truncated by an extra row or column in
+ certain circumstances.
+
+ Fixed a bug in RangedPixelToPixelCopyTransparent() and
+ RangedPixelToPixelCopy() in EasyBMP_VariousBMPutilities.h which
+ checked the wrong variable (FromT instead of FromB) to see if
+ it was out of range.
+
+ Added extra checks to RangedPixelToPixelCopyTransparent() and
+ RangedPixelToPixelCopy() in EasyBMP_VariousBMPutilities.h to
+ prevent attempted access of out-of-range pixels.
+
+*--------------------------------------------------------------------*
+
+Version: 1.01
+ Date: 03-31-2006
+
+ Made only the short functions Square, IntSquare, IsBigEndian,
+ FlipWORD, and FlipDWORD inline functions in
+ EasyBMP_DataStructures.h.
+
+ Moved all code (other than inline functions) to EasyBMP.cpp.
+
+ Changed DefaultXPelsPerMeter and DefaultYPelsPerMeter to #define
+ lines in EasyBMP.h to make the library compatible with
+ with the header-code split.
+
+ Removed memory hole in ~BMP() where "delete Colors;" was used
+ instead of "delete [] Colors;". Likewise with MetaData1 and
+ MetaData2.
+
+ Fixed memory leak in BMP::SetBitDepth() by changing to
+ delete [] Colors;
+
+ Removed potential memory leak in BMP::WriteToFile() in 24- and
+ 32-bit writing where szTemp wasn't delete at the end of a row.
+
+ Fixed bug where XPelsPerMeter and YPelsPerMeter weren't
+ properly initialized in the BMP::BMP() constructor, leading
+ to strange horizontal and vertical resolutions.
+
+ Fixed memory leak in BMP::ReadFromFile() where TempSkipBYTE
+ wasn't deleted.
+
+ Fixed memory leak in BMP::ReadFromFile() where szTemp wasn't
+ deleted.
+
+ Added BMP::TellVerticalDPI() and BMP::TellHorizontalDPI()
+ functions to give this information. If those values have
+ not yet been set, then they are first set to the EasyBMP
+ defaults of 96 dpi.
+
+ Set uninitialized RGBApixel values to white (255,255,255,0)
+ in a few functions for the BMP class.
+
+ Added a sample cpp application and makefile.
+
+*--------------------------------------------------------------------*
+
+Version: 1.02
+ Date: 05-29-2006
+
+ Inserted a line into EasyBMP.h to suppress the Visual Studio
+ warnings. We'll keep using the C++ standard fopen for now
+ until fopen_s becomes a real standard.
+
+ Moved the code sample and makefile to a subdirectory, so that
+ unzipping EasyBMP#_##.zip into a project directory doesn't
+ overwrite any crucial makefiles.
+
+ Improved SafeFread() to check if the proper amount of data
+ could be read.
+
+ Dramatically cleaned up ReadFromFile() code for 1 and 4
+ bpp files.
+
+ Fixed a typo (draw.o) in the sample makefile.
+
+ Modified ReadFromFile() to use buffering when reading the pixel
+ data. This should substantially improve disk access performance.
+ Only 16 bpp files are read in the old, slower way.
+
+ Changed DWORD from unsigned long to unsigned int. This should
+ fix the issue where 64-bit machines see DWORD as an 8-byte
+ data type, rather than 4 bytes. (Thank you to Bas Wegh!)
+
+ Renamed BYTE, WORD, and DWORD data types to ebmpBYTE, ebmpWORD,
+ and ebmpDWORD to eliminate the possibility of conflict with
+ windows applications, particularly with 64-bit windows, which
+ likely uses 8 byte DWORDS.
+
+ Modified WriteToFile() to use buffering when reading the pixel
+ data. This should substantially improve disk access performance.
+ Only 16 bpp files are read in the old, slower way.
+
+ Added new function, EasyBMPcheckDataSize(), to check that
+ the ebmpBYTE, ebmpWORD, and ebmpDWORD types have the correct
+ type.
+
+ Added some new macros of the EasyBMP version number for easier
+ version checking. New versions include _EasyBMP_Version_
+ (a double), _EasyBMP_Version_String_ (a char* version), and
+ _EasyBMP_Version_Integer_ (an integer version, e.g., 102).
+
+*--------------------------------------------------------------------*
+
+Version: 1.03
+ Date: 06-20-2006
+
+ Inserted a line into EasyBMP.h to suppress the Visual Studio
+
+ Added a check to BMP.SetColor() to ensure that the color table
+ is defined before attempting to set a color entry.
+
+ Added a check to BMP.GetColor() to ensure that the color table
+ is defined before attempting to retrieve a color entry.
+
+ Simplified the conditional in BMP.WriteToFile() from
+ if( BitDepth == 1 || BitDepth == 4 || ... ) to the simpler
+ if( BitDepth != 16 ).
+
+ Removed the old, unused code for writing 1- and 4-bit files
+ from BMP.WriteToFile().
+
+ Removed the line Colors = new RGBApixel [NumberOfColors]; in
+ BMP.ReadFromFile(). This operation is already covered by the
+ earlier SetBitDepth() call, and may contribute to a memory
+ leak. Furthermore, for files that had fewer than expected
+ number of colors (e.g., an 8-bit file with 236 colors), it
+ lead to memory access errors in BMP.GetColor() and BMP.SetColor().
+ (In fact, this is the main motivation for release 1.03.)
+
+ Added a warning when BMP.ReadFromFile() encounters an under-
+ specified color table, and code to pad the table with white
+ entries.
+
+ Added screen output on EasyBMP version and project website to
+ the code sample.
+
+*--------------------------------------------------------------------*
+
+Version: 1.04
+ Date: 07-22-2006
+
+ Removed the assignment to the integer i in IntPow() to eliminate a
+ Borland compiler warning.
+
+ Removed the assignment to the integer i in the Read##bitRow()
+ functions to eliminate Borland compiler warnings.
+
+ Removed the assignment to ZeroWORD in line 478 of EasyBMP.cpp in
+ BMP::WriteToFile() to eliminate Borland compiler warnings.
+
+ Removed the assignment to ZeroWORD in line 825 of EasyBMP.cpp in
+ BMP::ReadFromFile() to eliminate Borland compiler warnings.
+
+ The Borland warnings about conditions always being false are
+ incorrect. (Lines 1587, 1594, and 1601.) Likewise, the Borland
+ warnings about unreachable code (lines 1589, 1596, and 1603) are
+ incorrect. This code serves as a protection on unexpected hardware
+ where the data types may not be of the correct size, and helps to
+ future-proof EasyBMP. The first time this type of error was
+ encountered was on 64-bit CPUs, where the size of the DWORD was
+ larger than assumed when writing EasyBMP. Therefore, we will not
+ "correct" these "errors" detected by Borland. If they bother you,
+ compile with the -w-8008 and -w-8066 options.
+
+ Borland issues warnings about argc and argv being unused in the
+ sample project. These are silly warnings and will be ignored. If
+ this warning bothers you, compile with the -w-8057 option.
+
+ Modified the sample makefile so that EasyBMP.o depends upon
+ EasyBMP.cpp and EasyBMP*.h in the current working directory, rather
+ than the parent directory.
+
+ Added a global EasyBMPwarnings boolean variable, and functions
+ SetEasyBMPwarningsOn() and SetEasyBMPwarningsOff() to enable and
+ disable EasyBMP warnings and errors. Note that this will not
+ disable error checking or any other EasyBMP behavior, other than
+ cout output of the warning and error messages.
+
+ Added the function GetEasyBMPwarningState() to query the EasyBMP
+ warning state. (Either warnings are enabled or disabled.)
+
+ Removed old commented code (Write1bitRow()) from EasyBMP.cpp.
+
+ Replaced the 24-bit EasyBMPbackground.bmp image in the code sample
+ with a dithered 8-bit version to reduce the download size of the
+ core library.
+
+*--------------------------------------------------------------------*
+
+Version: 1.05
+ Date: 11-01-2006
+
+ Renamed BytesRead to ItemsRead in the SafeFread() function in
+ EasyBMP.cpp for greater clarity.
+
+ Added a copy constructor to the BMP class. However, note that
+ passing by value is not recommended practice. (Passing by refer-
+ ence is much faster, and consumes less memory.)
+
+ Added a new function:
+ bool Rescale( BMP& InputImage, char mode, int NewDimension );
+ to resize an image. The mode variables are as follows:
+ 'P': resizes the image to a new percentage of the old size,
+ e.g., 42%, 13%, etc.
+ example: Rescale( SomeImage, 'p', 42 );
+ 'W': resizes the image such that the new width is as specified.
+ example: Rescale( SomeImage, 'W', 100 );
+ 'H': resizes the image such that the new height is as specified.
+ example: Rescale( SomeImage, 'H', 100 );
+ 'F': resizes the image to fit in a square of specified size.
+ example: Rescale( SomeImage, 'F', 100 ); // fits in 100x100
+ // box
+ All rescaling is done with bilinear interpolation.
+
+*--------------------------------------------------------------------*
+
+Version: 1.06
+ Date: 12-01-2006
+
+ Added includes for <cctype> and <cstring> to EasyBMP.h. These are
+ used and should have been included all along. This should help
+ with Intel icc compiling.
+
+ Fixed the && bug in the copy constructor. (Thank you to user
+ fcnature!)
+
+ Added image scaling to the supplied code sample.
+
+ Added GetPixle() and SetPixel() functions for future use. These
+ will be added to enable more careful use of the const keyword.
