1.3.5 (January 26, 2009)
18
=========================
22
* BMP and DIB formats were throwing an assertion for negative height
23
values. This caused the process to crash.
27
* Don't install Magick++ headers if C++ is disabled.
29
* Linux RPM SPEC file needs to always install the loadable module
30
.la files or else the modules won't load.
32
* Windows runtime DLLs were for the wrong compiler version,
33
resulting in failure to execute if the correct runtime DLLs are
42
* FITS: Parsing is more robust.
44
Performance Improvements:
48
1.3.4 (January 13, 2009)
49
=========================
57
* Now runs under Windows Vista (as a 32-bit application).
59
* Fix for colorspace transform math overflow in Q32 build.
63
* Windows build supports OpenMP and requires Windows 2000 or later
64
(source code still supports Windows '98).
66
* Support large files under Windows.
68
* Support reading/writing 16 and 24 bit float TIFF files.
70
* Support reading/writing 64 bit integer TIFF files.
72
* Added "Log", "Max", "Min", and "Pow" options to -operator.
76
* Debug logging now properly prints 64-bit offset values.
78
Performance Improvements:
80
* Improve resource estimation for Microsoft Windows systems.
82
1.3.3 (December 9, 2008)
83
========================
91
* 'identify' was throwing an assertion when used on colormapped
92
files (this bug was introduced by 1.3.2).
94
* With the -segment option, eliminate trashing the image colors when
97
* 'identify -format "%c"' now reports the entire comment regardless
100
* Argument to -convolve is no longer arbitrarily truncated so huge
101
convolution kernels may now be specified from the command line.
103
Performance Improvements:
105
* Image segmentation (-segment) is now accelerated using OpenMP and
106
uses several other tactics to improve execution performance.
108
* 'identify "*"' now successfully works in a 32-bit application when
109
used in a directory containing a million files.
111
* 'identify' now executes quickly when used on TIFF files.
113
1.3.2 (November 29, 2008)
114
=========================
122
* -roll was failing for colormapped images.
124
* VID: Memory leak fix.
126
* PREVIEW: Solarize parameter was wrong.
128
* Delegates previously using 'spawn' needed an ampersand so that
129
starting the child process does not hang the GUI.
131
Feature improvements:
133
* +profile now supports an exclusion syntax. For example ``+profile
134
'!icm,*'`` removes all of the profiles except for the ICM profile.
135
The new syntax also allows multiple profiles to be listed at once.
137
Performance Improvements:
139
* AdaptiveThreshold, Blur, Convolve, and MotionBlur no longer
140
process the opacity channel unless the image has one.
142

143
=========================
151
* RPM build, Fixes to successfully build binary RPMs for Red Hat

160
OpenMP for algorithms which may run slower on operating systems
161
with crummy thread libraries.
163
* JPEG, Allow user to specify DCT encoding method via
164
jpeg:dct-method define. Also allow control over whether huffman
165
encoding is used via jpeg:optimize-coding define.
167
Performance Improvements:
169
* OpenMP (parallel processing) improvements for these functions:
171
- Rotate by 90 and 270 degrees (-rotate)
173

542
the specified directory.
543
* Use the -create-directories option in conjunction with
544
-output-directory and 'mogrify' to create any necessary subdirectories.
545
* A Pixels resource limit is added. Use '-limit Pixels value' to limit
546
the maximum number of pixels in an image to 'value'.
547
* The already supported option '-type Optimize' is now honored by
548
formats that need to choose a subformat based on the properties of
549
the image. Grueling tests of many/all pixels are not performed
550
unless '-type Optimize' is supplied.
551
* Added a a -set option to the composite, convert, display, mogrify,
552
import commands in order to allow setting an image attribute.
553
* Display utility no longer defaults to reading from standard input if
555
* May now be configured to use the umem memory allocation library
556
available in Solaris 9, Update 3 and later, or from the portable umem
559
Coder additions/improvements:
561
* Replaced existing DPX "support" with all-new DPX support conforming
562
to the SMPTE 268M-2003 standard.
563
* Cineon reader completely rewritten.
564
* TIFF coder is completely re-written. Now supports reading and
565
writing RGB, CMYK, and grayscale, scanline-oriented TIFF images
566
with arbitrary (1 to 32 bits) depth. Includes support for tiled
567
TIFF, floating point TIFF, LogLuv TIFF, BigTIFF, arbitrary depths,

* Added ExportImageChannel() and ImportImageChannel() APIs to support
582
exporting and importing pixel regions with an arbitary range of (1
583
to 32) bits per quantum.
584
* Added image leveling methods for Magick++.
585
* Generalized GetImageAttribute() support for retrieving wildcarded
586
attributes so that an identify -format specification like
587
``"%[dpx:*]"`` works as expected.
588
* Incorporated changes changes necessary so that GraphicsMagick can
589
work with the Ch C/C++ interpreter from SoftIntegration at
590
http://www.softintegration.com/.

596
* Added MagickRealloc() and deprecated ReacquireMemory().
597

599
Performance improvments:
601
* The DispatchImage() and ConstituteImage() functions incorporate
602
special case code for BGR, BGRO, BGRP, RGB, RGBO, and I formats (8
603
bit only) in order to improve performance dramatically.
604
* When writing very large JPEG images, don't enable Huffman compression
605
since doing so requires libjpeg to buffer the entire image in memory.
606
* When using the 'identify' -verbose option, -verbose must be specified
607
twice in order to obtain the color count. This makes normal use of
608
-verbose much faster.

* For the MinGW and Cygwin builds, the Magick++ library is forced to
618
build as a static library since otherwise C++ exceptions don't work.
619
* MinGW cross-build is available from a Linux or FreeBSD host.
620
* Determine location of Ghostscript fonts only once in order to improve
622
* Updated bzip2 to 1.0.4.

628
* Updated zlib to 1.2.3.
629
* Libtiff supports LZW compression.
630
* X11 is no longer part of the default build and will not be included
631
in the distributed install packages (but can still be built).
632
* Find latest Ghostscript which idenfies itself as "GPL Ghostscript".
633
* Use GlobalMemoryStatusEx(), if available, to determine how much
634
physical memory is available. Important for large-memory machines.
635
* Fixed NTreaddir() so that it does not write beyond its buffer.
636
* Fixed opendir() emulation function so it can't overwrite the stack.
637
* FlashPIX library sources are no longer distributed in the Windows
638
source package and building FlashPIX is disabled by default.
639
FlashPIX may still be built by adding the library (separately
641
* Fix bitmap handle leak in CropImageToHBITMAP() and ImageToHBITMAP().
643
1.1 (Released April 4, 2004)
644
============================
648
* Semaphore fix which is necessary for proper multi-threaded operation.
649
* Configure script fix to ensure that -lfpx is not supplied to the C
650
compiler during subsequent tests since this fails on some systems.
651
* Fix for East and West gravity computations.
652
* System error reports (errno) associated with an exception are now
653
correctly obtained from the context existing when the exception was
654
thrown rather than the context of the reporting function.
655
* JNG encoder fix. Files were being written with incorrect
656
alpha_sample_value in the header. These can be repaired by reading
657
them into GM 1.1 and rewriting them.
658
* XPM fix to module registration.
659
* PSD fix for index calculation when QuantumDepth>8.
660
* Validate that geometry specifications only include allowed
662
* SGI fix to save compression type while writing.
663
* EXIF attributes were not being retrieved when requested.
664
* Fix for bug when reading an image via a user-provided file
666
* The reported image magick string is now always that of the original
667
input file (it was sometimes being reported as the format produced by
668
an intermediate delegate program).
669
* Fixes to color profiling of CMYK images.
670
* Memory leak fixed in DrawClipPath().
671
* Arc drawing is fixed.
672
* Command-line parsing bug under Linux due to Linux's sscanfs
673
inability to parse strings like "0x1" as "%fx%f" is fixed.
674
* Scaling of 5 and 6-bit colors was slightly incorrect in BMP, AVI,
675
DIB, and TIM datastreams.
676
* GM utility now reports an error rather than silently returning if
677
an unsupported sub-command is provided.
678
* TIFF coder was writing 16-bit per sample RGB images incorrectly on
681
Performance improvements:
683
* Texture tiling is now 7X faster.
684
* Color profile processing speed improvements for colormapped images.
686
Utilities enhancements:
688
* For Unix, 'gm version' now includes a dump of the configure and
690
* Logging of thrown exceptions is now supported. Use '-debug
691
exception'. This is useful to learn when and where errors are
693
* The -define option is added in order to support supplying
694
additional options to coders without needing to add additional
695
command line options or structure members.
696
* The output of 'gm identify -verbose' now provides a nice dump
698
* The -sampling-factor option now accepts as many HxV pairs as
699
there are JPEG components. Omitted ones default to 1x1.
700
* The convert and montage commands now support an -operator command to
701
perform arithmetic and bitwise operations on specified image channels.
703
Coder additions/improvements
705
* The META coder supports wide characters for the IPTC and 8BIM
707
* The XTRN coder now supports wide characters.
708
* An "IMAGE" coder is provided which provides access to a large
709
number of images (derived from XFig) suitable for use as patterns,
711
* The "PATTERN" coder now returns an image pattern tiled to size
712
(equivalent results to TILE:IMAGE:pattern). This is for ImageMagick
714
* The CINEON coder now supports reading and writing images in CINEON
715
"CIN" linear gray and RGB formats. The read support is still very
716
weak, but it works for common images.
717
* The JPEG coder now estimates the original JPEG quality and sampling
718
factors and will reuse these options when writing JPEG if the image
719
is of the same type and the option "-define JPEG:preserve-settings"
721
* The JPEG-2000 coder now supports all Jasper library arguments using
722
command line syntax similar to '-define jp2:rate=0.5'.
723
* Reading and writting compressed SVG (SVGZ) is now supported.
724
* The TXT coder now observes depth when writing.
725
* The TIFF coder now outputs colormapped images with 1, 2, 4, and 8
726
bits per sample in order to provide much smaller file sizes for
727
images with very few colors.
728
* Many TIFF coder enhancements. Now reads colormapped and grayscale
729
images at arbitrary (even odd) bits-per-sample sizes. Now properly
730
supports an opacity channel (at any bits-per-sample value) for
731
grayscale images. Bilevel grayscale images are treated similar to any
732
other grayscale image unless CCITT FAX3/FAX4 compression is
733
requested. Now allows the user to specify an arbitrary
734
bits-per-sample value for grayscale images (even odd values) using
735
"-define tiff:bits-per-sample=value". Now automatically stores the
736
image as TrueColor RGB pixels if the image compression is set to JPEG.
737
TIFF files are now written in using the TIFF library's default endian
738
order rather than always big endian.
739
* The WPG coder now renders embedded WMFs.
740
* The PS3 coder is completely re-written to work much better and
741
support more features (see ChangeLog).
743
Code structure enhancements:
745
* Error handling has been improved and validated through testing.
746
Some errors were being lost, unnecessarily ignored, or reported as
747
something else entirely.
748
* The number of error text messages to be maintained has been reduced
749
by consolidating similar messages.
750
* The memory allocator functions have been replaced with similar
751
macros in order to eliminate warnings with GCC 3.3, avoid
752
accidentally casting away const, and allow memory debuggers to
753
report memory allocations and frees against the correct functions.
754
The previously-used functions remain in the library for the purpose
756
* <magick/xwindow.h> no longer depends on magick_config.h defines.
757
* The text string localization code has been replaced with a simpler
758
version written by Bill Radcliffe.
759
* Added key,value "map" APIs (somewhat similar to C++'s <map>) for
764
* Incorporated John Cristy's Wand API's in a new GraphicsMagickWand
766
* API definition is no longer dependent on types which vary in size
767
(e.g. size_t) depending on large file compilation options. This means
768
that applications may now be compiled without any special large file
769
options and still work properly with the library.
770
* Thrown exceptions (ExceptionInfo structure) now include source
771
file, source line, function name, and current system error number.
772
* The GetMagickInfoArray() function is added to replace use of
773
GetMagickInfo() for code which needs to access the coder list. This
774
is necessary since invoking GetMagickInfo() may re-order the coder
775
list, causing problems for code which traverses the list. Using
776
GetMagickInfo() to access individual list elements is safe.
777
* Added the CopyException function to support copying exception info
778
from one structure to another.
779
* Added the ReplaceImageInList function to replace an image in an
781
* Added the DrawPeekGraphicContext function to access the current
782
DrawInfo structure in the drawing context stack. Use of this
783
function is not recommended since it voilates proper programming
784
practices. It is added to support the Wand API's.
785
* GetImageDepth() now returns an integral value between 1 and
786
QuantumDepth and is no longer limited to the values 8, 16, and 32.
787
* SetImageDepth() supports setting the image modulus depth to any
788
integral value between 1 and QuantumDepth. This effects the effective
789
numeric precision, not the storage depth, since the quantum storage
790
type is still a Quantum.
791
* GetImageChannelDepth() supports retrieving the modulus depth for a
793
* SetImageChannelDepth() supports setting the modulus depth for a
795
* ProfileImage is updated to handle alpha channels and grayscale
797
* Added GetImageProfile() to retrieve a CMS profile from an image.
798
* Added SetImageProfile() to attach a CMS profile to an image without
799
adjusting the image pixels.
800
* Added DeleteImageProfile() to remove a CMS profile from an image.
801
* ConstituteImage() and DispatchImage() now support 'T' (transparency),
802
'O' (opacity), and 'P' (pad) options.
803
* CompositeImage() now supports CopyCyanCompositeOp,
804
CopyMagentaCompositeOp, CopyYellowCompositeOp, and
805
CopyBlackCompositeOp, composition operators.
806
* GetColorHistogram() obtains a color histogram for the image.
807
* QuantumOperatorImage() and QuantumOperatorRegionImage() support
808
arithmetic and bitwise operations on specified image channels.
809
* The semaphore.h header is no longer installed or included in the
810
API headers since these functions are private interfaces.
811
* Configure using --enable-symbol-prefix or define
812
PREFIX_MAGICK_SYMBOLS to use the C preprocessor to prefix all library
813
symbols with "Gm". This prevents library symbol conflicts with other
818
* Adjusted a number of function option names so that they match the
821
* Reading files (e.g. GIF) via a file descriptor is fixed.
825
* The TRIO library may be used to provide a replacement for vsnprintf
826
if the C library doesn't provide it. This improves security on old
828
* Configure only configures for C & C++ languages.
829
* Configure now does a better job of figuring out how to build a
830
thread-safe library across multiple operating systems.
831
* Configure incorporates a new mmap() test which tests the
832
functionality which is needed so that mmap() is not unnecessarily
833
rejected on a number of systems. This improves performance for large
834
files on those systems.
835
* Configure/build fixes for IBM's AIX operating system.
837
Windows-specific improvements:
839
* The static install package now uses the "uninstalled"
840
configuration so that it does not depend on the Windows registry in
841
order to run. This allows files from the static install package to
842
be copied to another computer without running an installer.
843
* The executable search path is extended at run-time to include the
844
directory where the CORE DLLs reside in order to ensure that they
846
* Adding the -t option to VisualMagick configure enables building
847
all of the coders into one library in order to save build time and
849
* The XTRN coder now supports wide characters.
850
* LCMS library updated to version 1.10.
851
* GMDisplay displays a checkerboard pattern behind transparent images.
852
* Support is provided for issuing log messages to the Windows standard
854
* Project files are now provided for use with Borland C++ Builder 6.0.
855
* Updated LCMS version to 1.12.
856
* Updated FreeType version to 2.1.5.
857
* Updated JBIG-KIT to version 1.5.
858
* Updated libpng to version 1.2.5.
859
* Updated libwmf to version 0.2.8.2.
860
* Updates zlib to version 1.2.1.
861
* ActivePerl 5.8.1 Build 807 now supported.
862
* GraphicsMagick now compiles using Visual Studio .NET 2003.

883
* CVS commit messages posted to graphicsmagick-commit mail list.
884
* CVS commit messages contain CVSWeb URL references.
886
Footprint changes from ImageMagick:
888
* Library -lMagick renamed to -lGraphicsMagick.
889
* Library -lMagick++ renamed to -lGraphicsMagick++.
890
* Utilities consolidated into a single 'gm' utility (e.g. use 'gm
892
* Script Magick-config renamed to GraphicsMagick-config.
893
* Script Magick++-config renamed to GraphicsMagick++-config.
894
* Headers installed under ${PREFIX}/include/GraphicsMagick.
895
* PerlMagick namespace renamed from "Image::Magick" to "Graphics::Magick".
896
* Pkgconfig files GraphicsMagick.pc and GraphicsMagick++.pc are
897
installed in $libdir/pkgconfig to assist pkg-config users.
898
* Coder modules installed to lib/GraphicsMagick-1.0/modules-Q8/coders.
899
* Filter modules installed to lib/GraphicsMagick-1.0/modules-Q8/filters.
901
Many performance enhancements:
903
* Default QuantumDepth is 8 since this is adequate for most purposes
904
and more efficient than 16.
905
* The Magick++ demo (compiled with QuantumDepth=8 and -O2) runs about
906
1.8X faster under SPARC/Solaris than the same demo with ImageMagick
908
* Colorspace transformations are much faster.
909
* Grayscale/monochrome image handling is much faster.
910
* PseudoClass image handling is faster.
911
* Text annotations using FreeType are much faster.
912
* Image file I/O is much faster.
913
* RLE-compressed MIFF reading much faster.
915
Code structure enhancements:
917
* All utility support functions moved to magick/command.c in order to
918
significantly reduce link dependencies, allowing statically-linked
919
programs to be smaller.
920
* Use of MogrifyImage() elminated except for by utilities.
921
* Re-builds due to changes to <magick/image.h> reduced by splitting the
922
header into multiple headers.
923
* ISO C '99 typedefs (gm_int16_t, gm_uint16_t, gm_int32_t, gm_uint32_t,
924
gm_int64_t, gm_uint64_t) are available for use.
926
Feature enhancements:
928
* Module loader always enabled for shared builds to allow extension.
929
* Loading of arbitrary filter modules (via -process option) supported
930
under Unix as well as Windows.
931
* SVG coder allows specifying size and initial background color.
932
* JPEG-2000 coder (JP2) updated to work with Jasper 1.7.
933
* HWB and HSL image colorspace translation support.
934
* JNG/MNG/PNG format support tracks ImageMagick version.
935
* BMP encoder can write 16-color indexed BMPs now as well as 2-color
936
BMPs (not restricted to monochrome).
937
* TIFF decoder now includes optimized support for tiled and stripped
939
* The -random-threshold option (RandomThresholdImage()) is added to
940
threshold an image to bilevel using random thresholding.
944
* 100% successful test completion at all quantum depths (8/16/32).
945
* A temporary file management subsystem is added to ensure that all
946
temporary files are removed before program exit. Temporary files are
947
created and used in a secure fashion to avoid the possibility that a
948
"trojan" temporary file (e.g. a symbolic link, or a file containing
949
unsafe content) is created before a delegate has the chance to write
950
to it. The environment variable MAGICK_TMPDIR allows the user to
951
specify where temporary files are created without altering where
952
other programs create their temporary files. Temporary filenames are
953
created in 8+3 format to hopefully be more acceptable to ralcgm.
954
* When dithering is disabled, don't dither when converting to a
955
PseudoClass, grayscale, or monochrome image. Disabling dithering
956
may cause these translations to be much faster.
957
* PICON format works with BLOBs.
958
* No longer removes input file when pinging a FlashPIX file.
959
* Arc drawing and texture fill fixes from ImageMagick.
960
* Sample, scale and affine fixes from ImageMagick.
961
* MIFF colormaps are now scaled properly while reading.
962
* CMYK translation works for QuantumDepth=32.
963
* ConstituteImage now works properly for grayscale images.
964
* Built-in tilde expansion and filename globbing now works properly.
965
* InitializeMagick now registers signal handlers to ensure that
966
resources are released before program exit. This helps avoid
967
temporary file leaks due to the user using "CONTROL-C".
968
* The installed <magick/magick_config.h> header now only contains
969
the few definitions required by the API headers. This should
970
significantly reduce or eliminate conflicts with other package
973
Windows platform enhancements:
975
* Configure updated for Visual C++ 7.0.
976
* OLE object (ImageMagickObject) re-written to work with Visual C++ 7.0
977
* New function, CropImageToHBITMAP(), to return a region of the image
978
as a Windows HBITMAP.
979
* Use vsnprintf to format strings under Windows (safer).
981
---------------------------------------------------------------------------
983
On November 19, 2002, GraphicsMagick was created as a fork of
984
ImageMagick, several days before the ImageMagick 5.5.2 release.
986
The objectives of GraphicsMagick are to:
988
* Use an open development model.
989
* Encourage new developers to join the project.
990
* Avoid unnecessary source code "churn".
991
* Establish and preserve a stable API.
992
* Use efficient coding practices which result in fast code.
993
* Improve memory efficiency.
994
* Use a release process which assures a working product.
995
* Maintain an accurate ChangeLog.
