2020-02-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* version.sh: Updates in preparation for the 1.3.35 release.
	Merge changes for 1.3.35 into GraphicsMagick-1_3 branch.

	* www/INSTALL-windows.rst: Update Windows installation and build
	documentation.

2020-02-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* NEWS.txt: Update with News since previous release.

	* magick/magick.c (InitializeMagickSignalHandlers): This private
	implementation function is now a static function as it should have
	been.
	(InitializeMagickEx): New function which may be used in place of
	InitializeMagick() to initialize GraphicsMagick.  This
	initialization function returns an error status value, may update
	a passed ExceptionInfo structure with error information, and
	provides an options parameter which supports simple bit-flags to
	tailor initialization.  The signal handler registrations are
	skipped if the MAGICK_OPT_NO_SIGNAL_HANDER flag is set in the
	options.

2020-02-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/magick.c (MagickToMime): Add a MIME translation for
	"jpg".  Issue reported by Pro Turm.

2020-02-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/INSTALL-windows.rst: Add quoting to avoid losing backslashes
	in Windows paths.

2020-02-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/common.h: Add missing unsupported handling for some
	recently added GCC/Clang attributes.

	* magick/: Move all remaining private implementation code in
	public headers which is guarded by MAGICK_IMPLEMENTATION into
	private headers, which are never installed.

2020-02-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/tiff.c (WriteTIFFImage): Evidence suggests that large
	strip sizes improve performance by reducing the number of I/Os.
	The defaults suggested by libtiff are way to small for today's
	images and computers.  Default TIFF strip sizes so that each
	uncompressed strip consumes up to 1MiB of memory, or 4MiB for FAX
	oriented codecs, or based on LZMA compression level when using
	LZMA compression.  The default size may be adjusted via the
	TIFF_BYTES_PER_STRIP preprocessor definition.

2020-02-09  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/wpg.c ZeroFillMissing data will never been triggered when
	y>=image->rows.

2020-02-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/render.c (DrawImage): Limit pattern dimensions by
	LONG_MAX rather than ULONG_MAX since this seems more likely to
	avoid arithmetic overflows later on.

2020-02-09  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/wpg.c Check for exception in image.

2020-02-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (VersionCommand): Add Google perftools tcmalloc
	to the available feature support.

	* www/INSTALL-unix.rst: Include some information about building
	with MSYS2.

	* coders/png.c (ReadOnePNGImage): Eliminate compilation warnings
	about signed/unsigned comparisons.

	* magick/image.c: Remove private global string constants, and one
	private global unsigned long constant, from the library ABI.
	Since the global constants were declared via a private header and
	only used within the GraphicsMagick build, removing these does not
	impact the public ABI.  The globals removed are BackgroundColor,
	BorderColor, DefaultTileFrame, DefaultTileGeometry,
	DefaultTileLabel, ForegroundColor, HighlightColor, MatteColor,
	PSDensityGeometry, PSPageGeometry, and DefaultCompressionQuality.

2020-02-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/render.c (DrawImage): Apply draconian pattern
	specification offset and dimension validations.  Hopefully there
	is no impact to usability.  If so please report it as a bug.
	Fixes oss-fuzz 20586 "graphicsmagick:coder_MVG_fuzzer:
	Integer-overflow in DrawPolygonPrimitive".

	* coders/svg.c (ReadSVGImage): Fix dereference of NULL pointer
	when stopping image timer.

2020-02-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/pict.c (DecodeImage): Allocate extra scanline memory to
	allow small RLE overrun.  Fixes oss-fuzz 20271
	"graphicsmagick:coder_PICT_fuzzer: Heap-buffer-overflow in
	ExpandBuffer" and 20272 "graphicsmagick:coder_PICT_fuzzer:
	Heap-buffer-overflow in DecodeImage".

	* PerlMagick/t/wmf/read.t: Update WMF reference images.  Relax
	test requirements for ski.wmf.

	* locale/C.mgk: Correct error message associated with
	"UnsupportedNumberOfRows".  Patch was submitted by Thorsten
	Alteholz via private email on 2020-02-05.

2020-02-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/topol.c: Include magick/magick_endian.h.

2020-02-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick, coders, wand: Added copious casts to avoid possible
	integer overflows in the Microsoft Windows 64-bit build, where
	sizeof(long) < sizeof(size_t).

2020-01-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/render.h ("PrimitiveInfo"): Change PrimitiveInfo
	coordinates from type 'unsigned long' to 'size_t'.

2020-01-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/gradient.c (GradientImage): Warnings reduction, plus note

	* coders/pcd.c (DecodeImage): Assure that pcd_length gets
	initialized with something.

	* Magick++/lib/Options.cpp (strokeDashArray): Add needless check
	for _drawInfo->dash_pattern null in order to make static analysis
	happy.

	* magick/render.c (DestroyPolygonInfo): Make sure to not
	dereference a null edges pointer.

	* coders/pdb.c (WritePDBImage): Make sure that null comment value
	is not dereferenced.

	* coders/vid.c (ReadVIDImage): Make sure that
	ThrowVIDReaderException does not dereference a null pointer.

	* magick/quantize.c (ClassifyImageColors): Fix error handling so a
	null pointer won't be consumed after a memory allocation failure.
	Changed the location of some variable declarations and added some
	comments.

2020-01-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/caption.c (ReadCAPTIONImage): Assure that metrics are
	initialized.

	* magick/pixel_cache.c (DestroyThreadViewSet): Check if views
	pointer is not null before destroying views.

	* coders/xpm.c (ReadXPMImage): Properly detect the case where the
	XPM colormap is not fully initialized.

	* coders/pict.c (DecodeImage): Fix heap buffer over-reads. Fixes
	oss-fuzz issue 20053 "graphicsmagick:coder_PICT_fuzzer:
	Heap-buffer-overflow in ExpandBuffer" and oss-fuzz issue 20048
	"graphicsmagick:coder_PICT_fuzzer: Heap-buffer-overflow in
	DecodeImage".  Both of these oss-fuzz issues appeared due to
	recent changes since the last release.

	* coders/meta.c (WriteMETAImage): Assure that 'iptc_offset' is
	initialized and valid.

	* coders/jpeg.c (ReadJPEGImage): Assure that evaluating the
	embedded profile length does not suffer from undefined behavior.

2020-01-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/render.c (DrawImage): Add more MVG parser validations.

2020-01-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/histogram.c (WriteHISTOGRAMImage): Histogram coder was
	relying on the previously removed '@' file inclusion feature to
	insert the histogram comment text.  Write a PseudoClass MIFF image
	with RLE compression.  Fixes SourceForge issue #622 "Histogram
	produces incorrect color table attribute ".

	* magick/pixel_cache.c (ModifyCache): Re-open the pixel cache if
	the cache rows/columns do not match the owning image rows/columns.

	* magick/transform.c (TransformImage): TransformImage now returns
	a MagickPassFail return status value rather than void.

	* coders/pict.c (ReadPICTImage): Fix some over-strict validations
	which were preventing some PICT files which were previously read
	successfully from being accepted. Fix problems which occurred when
	the clipping rectangle changed the image size. Improve reading
	embedded JPEG blobs.  Now successfully reads all raster PICT files
	I have available.

2020-01-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/pict.c (ReadPICTImage): Be more strict about PICT
	rectangle by treating rectangle dimensions as if they are a 16-bit
	signed type and not allowing negative values.  Avoid GCC warnings
	which sprung up similar to "warning: comparison is always false
	due to limited range of data type".

2020-01-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/sfw.c (ReadSFWImage): Restore a DestroyImage() statement
	which was accidentally deleted by recent edits.  Fixes oss-fuzz
	"Issue 19819 in oss-fuzz: graphicsmagick:coder_SFW_fuzzer:
	Indirect-leak in AllocateImage".

	* coders/png.c (WriteOneJNGImage): Detect when JPEG encoder has
	failed, and throw exception.  Fix image dimension limit
	validations.  Stop discarding exception report.  Fixes SourceForge
	bug #621 "Assertion in WriteBlob at magick/blob.c:4937" which was
	reported by Suhwan Song.

	* coders/pict.c (WritePICTImage): Eliminating small buffer overrun
	when run-length encoding pixels.  Fixes SourceForge bug #620
	"heap-buffer-overflow in EncodeImage at coders/pict.c:1114" which
	was reported by Suhwan Song.

	* coders/logo.c (ReadLOGOImage): PATTERN error handling was
	incomplete.  Add appropriate error handling.
	(ReadLOGOImage): Switch to using ConstituteTextureImage() rather
	than TextureImage() since it is more appropriate for this purpose.
	(ReadLOGOImage): Oops!  Accidental change of behavior. When size
	is not supplied, simply return the pattern image.

2020-01-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/*.c (ReadFOOImage): Stop image timer just before
	returning from reader so that reported timings are correct when
	used in the future.

2020-01-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/timer.c (StartTimer): Expose previously existing
	StartTimer() function.
	(StopTimer): Expose previously existing StartTimer() function.

	* magick/constitute.c (WriteImage): Don't over-write time-stamp
	when output is to INFO format.

2020-01-03  Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* VisualMagick\configure\configure.exe: Should not depend on mfcr90.dll.
	It is too bad when end user cannot run this tool because of missing DLL.

	* VisualMagick\configure\configure.cpp Make speed optimisation as default
	option.

	* VisualMagick\configure\configure.vcproj Give different filename to debug
	build to avoid accidental committing debug build to repository.

2020-01-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/dpx.c (GenerateDPXTimeStamp): Use reentrant localtime_r()
	function if it is available.

	* magick/log.c (LogMagickEventList): Use reentrant
	localtime_r() function if it is available.

	* coders/cineon.c (GenerateCineonTimeStamp): Use reentrant
	localtime_r() function if it is available.

	* coders/mat.c (WriteMATLABImage): Use reentrant localtime_r()
	function if it is available.

	* coders/pdf.c (WritePDFImage): Use reentrant localtime_r()
	function if it is available.

	function if it is available.

	* magick/magick.c (InitializeMagickSignalHandlers): Use the normal
	termination signal handler for SIGXCPU and SIGXFSZ so that ulimit
	or setrlimit(2) may be used to apply CPU (RLIMIT_CPU) and output
	file size (RLIMIT_FSIZE) limits with the normal cleanup, and
	without dumping core.  Note that any output files currently being
	written may be truncated and files being written by external
	programs (e.g. Ghostscript) might be left behind unless they are
	to a temporary file assigned by GraphicsMagick.

	* coders/xpm.c (ReadXPMImage): Promote a color-lookup
	warning to an error.

	* coders/xc.c (ReadXCImage): Promote a color-lookup
