![]() ![]() ![]() In fact, GraphicsMagick does support most of the features described. The link to the ImageMagick usage page is appreciated, but the implication is that GraphicsMagick does not support most of those features. Only a few algorithms remain to be re-implemented. When GM 1.3 is released, most algorithms will be OpenMP accelerated, well tuned, and tested with several different OpenMP-capable compilers on a wide variety of platforms. ![]() It is true that ImageMagick has been releasing OpenMP features earlier than GraphicsMagick but this is because of the difference in development model. Subsequent testing shows that ImageMagick has responded to these benchmark results by eliminating many of the performance issues uncovered by the benchmark. The benchmark has since been updated to use the new ImageMagick syntax. The benchmark was correct for the ImageMagick release which was benchmarked but ImageMagick has changed its syntax since then. I am the principle maintainer of GraphicsMagick. Hi, this is a response to Chris Madison’s post. The GM developers are working on getting OpenMP into GM but OpenMP support has been included in ImageMagick for some time now.įinally, ImageMagick supports hundreds of features that GraphicsMagick does not. blur only red channel), support for CMYKA images, and ImageMagick is thread-safe whereas GraphicsMagick is not. GraphicsMagick likely has that as it was an early offshoot of ImageMagick. I do not know Graphicsmagick, but the alternative to -annotate in ImageMagick is most likely -draw. ImageMagick in some cases runs a bit slower than GraphicsMagick mainly because it supports additional features such as full alpha support, most algorithms permit channel selection (i.e. In the older ImageMagick and possibly in GraphicsMagick, turning on alpha was -matte and turning off alpha was +matte. Instead comment out the export statement to get a proper comparison or correct the values (use 4000mb instead of 4000). With GraphicsMagick working in memory and ImageMagick on disk we would expect a significant slowdown with ImageMagick. Tags GraphicsMagick, ImageMagick, graphics, boost, image Maintainers hhatto Classifiers. Skip to main content Switch to mobile version. We did notice the benchmark script forces ImageMagick to cache the pixels to disk with these lines:Įxport MAGICK_MAP_LIMIT MAGICK_MEMORY_LIMIT MAGICK_AREA_LIMIT Yet Another Python wrapper for GraphicsMagick. We ran the benchmarks against a modern version of ImageMagick (6.4.3) and got dramatically different results. ![]()
