  • Followup: RE: montage generates multiple output files

    With default options, only so many tiles can fit in one image so multiple output images need to be generated. PNG format only supports one page per image. Use the -tile option to specify how many thumbnail tiles (WIDTHxHEIGHT) to include in one output image. For example "-tile 40x50". Bob.

  • Comment: gm convert causes 100% cpu load

    The good news is that I am able to reproduce this problem. Thanks for reporting it.

  • Comment: PSD files are rendered wrong

    GraphicsMagick's composite does not expand results. It simply ignores pixels in the second image which fall outside the boundaries of the first ("canvas") image, given the composition offsets for the second image. This means that there are two strategies which will work. One strategy is to expand/crop the base canvas image (first image in list) to be the final size. The other is to add a way...

  • Comment: PSD files are rendered wrong

    I should mention that if the PSD reader offered a mode to flatten as it goes, then quite a lot less memory would be required. Memory can be a factor for large files.

  • Comment: PSD files are rendered wrong

    Most of the slowness I am seeing seems to be due to the decompressor implementation which reads data one character at a time in the slowest possible fashion. You can see where the slowness is occuring by adding the -monitor option so that you can see the file loading progress as well as the time to do the 'flatten'. I see a whole lot of nothing (long delay) followed by a very fast set of...

  • Comment: PSD files are rendered wrong

    Toby fixed the parsing but it seems that the hidden layers are still included in the composition so this bug is not quite fixed yet. When things are working you should be able to do gm convert picedit.psd -flatten picedit.jpg or gm convert picedit.psd -flatten x: to preview the result on an X11 display. Currently the 'display' function is not very friendly since it does not...

  • Im4java works with GraphicsMagick too!

    Hi, Im4java works with GraphicsMagick as well as ImageMagick. The SourceForge page and project description should mention that im4java also works with GraphicsMagick. Bob.

  • Followup: RE: GM slower than IM rotate 45

    Benchmarks are only benchmarks and not "gospel". Different computers and operating systems behave differently. I recommend trying GraphicsMagick configured with this option: --disable-openmp-slow to see if that helps. It should help for CPUs where there is more contention when cores access main memory, such as the Intel Core 2 and older Xeon systems. It turns out that...
