    21  
    22  	* magick/utility.h (MagickSafeMultiplySize_t): New function to
    23  	perform a safe multiply.  A multiplication overflow results in
    24  	zero.
    25  	(MagickAllocateMemory): Check for size_t value truncation/overflow
    26  	and zero size before deciding to allocate memory.  Any detected
    27  	failure results in a NULL pointer being returned.

    49  
    50  2007-11-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
    51  
    52  	* magick/constitute.c (ReadImage): Log colorspace of returned image.
    53  	(WriteImage): Log colorspace of image to be written.

    57  	* magick/{constitute.c,xwindow.c}: Use MagickBoolToString().
    58  
    59  	* magick/image.h (MagickBoolToString): New macro to convert truth

    61  
    62  2007-11-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
    63  
    64  	* magick/image.c (IsImagesEqual): Allow comparing images if the
    65  	colorspace enumeration is different but the images are both an RGB
    66  	type.
    67  
    68  2007-11-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
    69  
    70  	* magick/command.c: Add support for -monitor option to `animate`,
    71  	`display`, and `import`.
    72  
    73  	* coders/fpx.c (WriteFPXImage): Fix compilation problem.
    74  
    75  	* coders/dpx.c (TentUpsampleChroma): Fix access beyond array.  Use
    76  	integer calculations where possible.

    87  
    88  2007-10-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
    89  
    90  	* magick/blob.c (ReadBlob?SBFoo): Return 0 on EOF conditions
    91  	rather than a magic value concocted using ~0.  The magic value was
    92  	very sensitive to the size/range of the type used to pass and
    93  	store it, leading to increased possibility of error.  There was
    94  	also concern that sometimes a successfully read value may match
    95  	the magic value.  Added documentation that EOFBlob() may be used
    96  	to determine that the blob is in EOF state.
    97  
    98  	* coders/pix.c (ReadPIXImage): Avoid reliance on a particular
    99  	magic value being returned from ReadBlobMSBShort on EOF.
   100  
   101  	* coders/avs.c (ReadAVSImage): Avoid reliance on a particular
   102  	magic value being returned from ReadBlobMSBLong() on EOF.
   103  
   104  2007-10-07  Fojtik Jaroslav  <JaFojtik@seznam.cz>
   105  
   106  	* wpg.c: Monochrome images are not using palette - 
   107  	palette is discarded in this case.
   108  
   109  2007-10-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   110  
   111  	* magick/blob.h: Blob I/O APIs now use sized types so that passed
   112  	and returned data values are a specific size rather than
   113  	architecture dependent.
   114  
   115  	* PerlMagick/t/read.t: Added read test for unsigned 32-bit LSB MAT
   116  	format.
   117  
   118  2007-10-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   119  
   120  	* coders/dib.c (ReadDIBImage): Use appropriate sized cast for DIB
   121  	width and height values.  Validate width and height values.
   122  
   123  	* coders/bmp.c (ReadBMPImage): Use appropriate sized cast for BMP
   124  	width and height values.
   125  
   126  	* magick/colorspace.c (RGBTransformImage): Use a better rounding
   127  	algorithm when converting to HSL/HWB colorspaces.
   128  
   129  	* magick/gem.c (TransformHSL): Avoid GCC opimization bug on
   130  	Opteron which caused wrong results.  Ensure that returned values
   131  	fall within bounds 0.0 to 1.0.
   132  	(TransformHWB): Avoid GCC opimization bug on
   133  	Opteron which caused wrong results.  Ensure that returned values
   134  	fall within bounds 0.0 to 1.0.
   135  
   136  	* PerlMagick/t/ttf/read.t: Relax strictness quite a bit for TTF
   137  	read tests in order to allow somewhat different FreeType output.
   138  
   139  2007-09-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   140  
   141  	* magick/colorspace.c (RGBTransformImage): Add missing break
   142  	statement. HWB colorspace was used rather than HSL.
   143  	(TransformRGBImage): Add missing break
   144  	statement. HWB colorspace was used rather than HSL.
   145  
   146  2007-09-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

   156  
   157  	* magick/shear.c (IntegralRotateImage): Rotation by 270 degrees

   159  
   160  2007-09-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   161  
   162  	* magick/command.c (CommandProgressMonitor): Remove any preceding
   163  	whitespace in the task descriptions so that we don't need to

   213  	user.
   214  
   215  	* coders/jpeg.c (TerminateDestination): Don't invoke SyncBlob()

   226  
   227  	* coders/tiff.c (WriteTIFFImage): Ensure that selected photometric
   228  	most closely matches the user's expectation.  Remove compression
   229  	if requested compression type is not compatible with the selected
   230  	photometric.
   231  
   232  2007-09-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

   299  
   300  2007-09-01  Fojtik Jaroslav  <JaFojtik@seznam.cz>
   301  
   302  	* coders/bmp.c Ability to read true color bitmap with invalid palette size

   316  
   317  	* coders/tiff.c (WriteTIFFImage): Logic which decided the output
   318  	subformat to write was too convoluted to understand, and in fact
   319  	palette images were not be written sometimes when they should be
   320  	(bug added on 2007-08-19).  Deleted the convoluted code and
   321  	replaced with a different design which should be more correct and
   322  	flexible.
   323  	(ReadTIFFImage): Decided to read bilevel TIFF using a colormap
   324  	since there are significant internal advantages to doing so.
   325  	However, the writer is carefully designed to output normal bilevel
   326  	TIFF so this should not annoy TIFF users.
   327  
   328  	* magick/constitute.c (ImportImagePixelArea): Re-wrote grayscale
   329  	pseudoclass import to be more efficient and more tidy.

   644  
   645  	* tests/Makefile.am: Don't test PTIF format with blob I/O since it
   646  	is not possible to pass the rwblob test and it is really an output

   737  
   738  	* magick/utility.h (MagickReallocMemory): It seems that realloc()
   739  	frees the provided memory pointer if the requested size is zero.
   740  	This was causing MagickReallocMemory() to perform a double-free
   741  	under error conditions.  Inspired by Debian
   742  	realloc_double_free_fix patch by Daniel Kobras.
   743

   777  2007-07-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   778  
   779  	* magick/forward.h: New header file to support forward type
   780  	declarations.
   781  
   782  	* coders/pnm.c (ReadPNMImage):  Fix pixel scaling problem caused by
   783          floating point rounding error.
   784  
   785  2007-07-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   786  
   787  	* magick/studio.h: Provide pread() and pwrite() prototypes if they
   788  	are missing.
   789  
   790  	* configure.ac: Check for missing pread() and pwrite() prototypes.
   791  
   792  	* m4/ac_func_fseeko.m4: Use fixed version of AC_FUNC_FSEEKO.
   793  
   794  	* magick/utility.c (SystemCommand): Avoid use of snprintf.
   795  
   796  2007-07-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   797  
   798  	* magick/blob.c: Only replace getc_unlocked() and putc__unlocked()
   799  	for a thread-safe build.
   800  
   801  	* magick/studio.h: Always use fseeko() and ftello() if they are
   802  	available.
   803  
   804  2007-07-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   805  
   806  	* coders/dpx.c (ReadDPXImage): Avoid using seek() if possible, and
   807  	don't use at all if the input is not seekable.
   808  
   809  	* coders/psd.c (ReadPSDImage): Eliminate memory leak when reading
   810  	PSD files.  Fixes Sourceforge issue 1625477 "Memory leak reading
   811  	layered PSD Image".
   812  
   813  2007-06-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   814  
   815  	* magick/command.c: Fixed -affine command argument
   816  	validation. Fixes SourceForge issue 1743141 "Affine matrix option
   817  	parsing".
   818  
   819  	* config/magic.mgk: Added detection for BigTIFF.
   820  
   821  	* coders/tiff.c: Preliminary work to support BigTIFF.
   822  
   823  2007-06-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   824  
   825  	* coders/dpx.c: Fix problems encountered when reading and writing
   826  	from/to pipes or compressed files.
   827  
   828  2007-06-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   829  
   830  	* coders/dpx.c (ReadDPXImage): Improved the pixel data marshalling
   831  	in order to obtain better read performance for 10-bit DPX.
   832  
   833  	* magick/blob.c (OpenBlob): Added support for MAGICK_MMAP_READ and
   834  	MAGICK_MMAP_WRITE environment variable options to enable input and
   835  	output file access using mmap().
   836  
   837  2007-06-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   838  
   839  	* magick/blob.c (OpenBlob): Use MAGICK_IOBUF_SIZE to tune the size
   840  	of the I/O buffer.  Sometimes performance is improved by using
   841  	something other than the current default of 16KB.
   842  
   843  2007-06-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   844  
   845  	* coders/miff.c (ReadMIFFImage): Handle case where compression
   846  	keyword is present but has value of `None`.
   847  
   848  2007-06-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   849  
   850  	* magick/blob.c (OpenBlob): Disable reading input files using
   851  	memory mapping since it has been learned that some operating
   852  	systems fail to do read-ahead on network files.  Without
   853  	read-ahead, performance is poor.
   854  
   855  	* magick/resource.c (AcquireMagickResource): Map resource limit
   856  	was not being properly checked due to a typo.  The memory limit
   857  	was being tested instead.
   858  
   859  	* coders/tiff.c (ReadTIFFImage): Use libtiff to decode OJPEG
   860  	compressed files into RGB.  Probably requires new OJPEG
   861  	implementation from Joris Van Damme which is new in libtiff and
   862  	not yet released. I am not completely sure that this approach is
   863  	correct yet.
   864  
   865  2007-05-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   866  
   867  	* magick/xwindow.c (MagickXGetWindowImage): Set image->depth
   868  	appropriately.
   869  
   870  	* many files: Compiler warnings reduction.
   871  
   872  2007-05-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   873  
   874  	* coders/cineon.c (ReadCINEONImage): Alter sample scaling
   875  	algorithm a bit.	
   876  
   877  	* tests/rwblob.c, tests/rwfile.c: Allow some slop when testing
   878  	Cineon format with QuantumDepth=8 since we are currently only
   879  	supporting 10 bit samples.
   880  
   881  2007-05-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   882  
   883  	* coders/jpeg.c (ReadJPEGImage): Fix reading 12-bit grayscale
   884  	JPEG.
   885  
   886  2007-05-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   887  
   888  	* coders/cineon.c (WriteCINEONImage): Re-wrote Cineon writer from
   889  	scratch.  There is no code originating from ImageMagick in this
   890  	source module any more.
   891  
   892  2007-04-30  Fojtik Jaroslav  <JaFojtik@seznam.cz>
   893  
   894  	* coders/art.c, coders.cut.c, coders/mat.c, coders/wpg.c: Add
   895  	support for PingImage() so that image identification is fast by
   896  	default.  Also eliminates error message produced by mat.c due to
   897  	rotating an image which has no pixel cache.
   898  
   899  2007-04-09  Fojtik Jaroslav  <JaFojtik@seznam.cz>
   900  
   901  	* coders/wpg.c (ReadWPGImage): Fix for SourceForge bug id 1431805
   902  	"clip art wpg files cause access violation in graphics magick".
   903  
   904  2007-04-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   905  
   906  	* magick/pixel_cache.c (ModifyCache): Ensure that the cache nexus
   907  	is open.  Fix for SourceForge bug id 1173713 "segfault in
   908  	ModifyCache"
   909  
   910  	* m4/acx_pthread.m4 (ACX_PTHREAD): Apply fixes necessary to
   911  	support C++ compiler properly.
   912  
   913  2007-04-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   914  
   915  	* magick/GraphicsMagick.pc.in: Fix for SourceForge bug id 1576616
   916  	"Fix includedir variable in pkg-config files".
   917  
   918  	* magick/pixel_cache.c (GetOnePixel): Fix for SourceForge bug id
   919  	1572357 "GetOnePixel definition appears incorrect".  It is true
   920  	that this function is intended for read-only purposes and that the
   921  	PixelPacket value is returned directly.
   922  
   923  	* coders/pdf.c (WritePDFImage): Fix for SourceForge bug id 1510075
   924  	"Failed to write PDF with JPEG compression".
   925  
   926  	* magick/command.c (MogrifyImageCommand): Properly bubble up
   927  	errors and terminate further mogrify processing immediately. This
   928  	in response to SourceForge bug id 1391421 "problem doing resize on
   929  	273x1 JPEG".
   930  
   931  	* magick/magick.c (InitializeMagickClientPathAndName): Fix for
   932  	SourceForge bug id 1315109 "segfault in InitializeMagick(NULL)".
   933  
   934  	* wand/magick_wand.c (MagickGetQuantumDepth): Fix for SourceForge
   935  	bug id 1353744 "MagickGetQuantumDepth doesn't work".
   936  
   937  	* PerlMagick/t/read.t: Added a test for WPG v1.
   938  
   939  2007-04-07  Fojtik Jaroslav  <JaFojtik@seznam.cz>
   940  
   941  	* coders/mat.c: Read Matlab files in both big and little endian
   942  	format.
   943  
   944  2007-03-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   945  
   946  	* coders/dpx.c (WriteDPXImage): Set DPX reference high quantity to
   947  	2.047 rather than 2.048 since zero is assumed to occupy one count
   948  	and 2.047 seems to be the convention even though the DPX
   949  	specification says the default is 2.048.  Technicolor uses 2.047.
   950  
   951  	* m4/acx_pthread.m4: Update version of ACX_PTHREAD macro used.
   952  
   953  2007-03-28  Fojtik Jaroslav  <fojtik@humusoft.cz>
   954  
   955  	* coders/wpg.c: Support CTM translation in WPG reader.
   956  
   957  2007-03-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   958  
   959  	* coders/dpx.c: Store 10-bit Luma samples in the filled 32-bit
   960  	storage word starting with the datum in the least significant
   961  	position.
   962  
   963  2007-02-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
   964  
   965  	* Updated autoconf to version 2.61.
   966  
   967  2007-02-10  Daniel Kobras  <kobras@debian.org>
   968  
   969  	* coders/palm.c: (ReadPALMImage) Do not implicitly call
   970  	ReadBlobByte() twice in Min() macro. Patch thanks to Vladimir
   971  	Nadvornik. This was a regression introduced in patch for
   972  	CVE-2006-5456. (CVE-2007-0770)
