> - magick/static.c: Use !defined(SupportMagickModules) to enable static module loader. Fixes SourceForge bug #543 "Multiple definition of "OpenModule" (etc) when cross-compiling shared".

2018-01-29 Greg Wolfe <gregory.wolfe@kodakalaris.com>

> - coders/svg.c (SVGStartElement): A terminating '>' in a geometry string is interpreted to mean that the dimensions of an image should only be changed if its width or height exceeds the geometry specification. For an unapparent and undocumented reason, a terminating '>', if present, was being nulled out, making this feature unusable for SVG files (now fixed).

> - coders/svg.c (ReadSVGImage): If there is a geometry string in image_info->size (e.g., gm convert -size "50x50%" in.svg out.png), AllocateImage() sets image->columns and image->rows to the width and height values from the size string. However, this makes no sense if the size string was something like "50x50%" (we'll get columns = rows = 50). So we set columns and rows to 0 after AllocateImage(), which is the same as if no size string was supplied by the client. This also results in svg_info.bounds to be set to 0,0 (i.e., unknown), so that svg_info.bounds will later be set using the image size information from either the svg "canvas" width/height or from the viewbox. Later, variable "page" is set from svg_info->bounds. Then the geometry string in image_info->size gets applied to the (now known) "page" width and height when SvgStartElement() calls GetMagickGeometry(), and the intended result is obtained.

> - coders/svg.c (SVGStartElement): When the density (DPI) is specified using the ImageInfo::density member, the derived scale factor is incorrectly applied a second time to the width and height members of variable RectangleInfo page. Fixes SourceForge ticket #451.

2018-01-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/static.c: Use a lazy-loader for static modules with the same external interface as the lazy-loader for dynamic modules.

2018-01-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - NEWS.txt: Prepare for 1.3.28 release.

2018-01-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - NEWS.txt: Update with changes since previous release.

2018-01-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - PerlMagick/Magick.xs: Compiler warnings reduction.
> - magick/pixel_cache.h: Mark GetPixels(), GetIndexes(), and GetOnePixel() as deprecated. Compilers may produce a warning if these functions are used.
> - magick/pixel_cache.c (InterpolateColor): Return black pixel if InterpolateViewColor() reports failure.
> - coders/png.c (ReadMNGImage): Fix memory leak of chunk and mng_info in error path.
> - coders/gif.c (ReadGIFImage): Fix memory leak of global colormap.

2018-01-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/symbols.h: Fix SourceForge issue #538 "13 symbols in common with ImageMagick despite --enable-symbol-prefix".
> - coders/bmp.c (ReadBMPImage): Fix non-terminal loop due to unexpected bit-field mask value. Fixes SourceForge issue #541 "Infinite Loop in ReadBMPImage (coders/bmp.c)".
> - coders/jpeg.c (JPEGMessageHandler): Revert code added on 2017-07-08 to promote certain warnings from libjpeg to errors. Add code to rationalize claimed image dimensions based on file size. Resolves SourceForge issue #539 "Images with libjpeg warnings result in error".

> - coders/wpg.c Recursive ReadImage could return multiple scenes
>     fixed.

2018-01-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/png.c (ReadOnePNGImage): Quit 'passes' loop if we encountered an error
> - magick/pixel_cache.c (SetNexus): Fix heap overwrite in AcquireCacheNexus() due to SetNexus() not using an allocated staging area for the pixels like it should. This problem impacts all 1.3.X releases. Resolves SourceForge issues 532 "heap-buffer-overflow bug in ReadWPGImage" and #531 "heap-buffer-overflow in AcquireCacheNexus".
> - magick/pixel_cache.c (InterpolateViewColor): Now returns MagickPassFail rather than void. Code using this function is updated to check the return status.

2018-01-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/describe.c (DescribeImage): Discriminate between AcquireImagePixels() returning NULL or finding a transparent pixel. This avoids use of a null pointer in the case where AcquireImagePixels() returns NULL.

2017-12-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/static.c: Change static module initialization to be based on an initialized list rather than a squence of function calls in order to simplify maintenance and possibly address future requirements.
