You should specify the -depth 5 and -compress none after you read the input image but that does not explain the problem Ahh, that's the problem - with the depth parameter before the source (albeit user error) I get no problem in 6.9 utilities/convert -depth 5 ~/Dropbox/Forum/original.png ~/Dropbox ...

hmm, I have trunk checked out nils ~/workspace/ImageMagick $ svn info Path: . Working Copy Root Path: /mnt/workspace/ImageMagick URL: https://subversion.imagemagick.org/subversion/ImageMagick/trunk Relative URL: ^/ImageMagick/trunk Repository Root: https://subversion.imagemagick.org/subversion ...

on the patch - what I actually did try out is trunk URL: https://subversion.imagemagick.org/subversion/ImageMagick/trunk which includes http://trac.imagemagick.org/changeset/17274. I do get perfect results with the 6.9 branch change, just to make sure can you double check trunk once more (I've built ...

on compress - ah, yes, I missed "convert -list compress", sorry

.. one more thing while you're looking if I may - an option for enabling RLE compression explicitly would be completing things

Hi, built and tested and it works with one caveat and I'm not sure that's an issue or not. If I start with an indexed png and convert it to 5 bit tga, all fine https://www.dropbox.com/s/4p093jw4i0cd60o/test-indexed.png?dl=0 https://www.dropbox.com/s/rm5i77zcdmz5kyu/test-indexed-5bit.tga?dl=0 ...

Excellent, thank you for the quick turn-around. If you'd like I could test out the tga 5 bit depth support before the release - it's probably just a diff on tga.c required?

In any case, thanks again

Ah, yes, I'm mixing up bits_per_pixel and depth, thanks

Apologies, I've messed up the files - here's an actual TGA input (says 5 bit which I find weird) and the 8 bit output that ImageMagick (built from source) converts to convert ~/Dropbox/Forum/original5bit.tga ~/Dropbox/Forum/converted8bit.tga converts to https://www.dropbox.com/s/4sfetbnyivj3kra ...

The original that I've downloaded (someone made in photoshop) - 16 bit

Hi ImageMagick 6.9.0-0 on windows reads the 16 bit fine but writes 8, 24 or 32 bit only. The special 16 bit encoding is described here http://www.fileformat.info/format/tga/egff.htm When a value of 15 appears in the PixelDepth field of the Image Specification section of the header, there are five ...

Hi

I'd love to see an option to convert to tga with 16 bit - not seeing that right now.

Thanks

.. reporting back that the dds generated by ImageMagick is actually nicely readable by another tool I've tried - paint.net

So I think I'll check with gimp folks and ddsviewer.com on possible problem in their dds file handling.

Thanks

Hi I'm trying to have image magick generate some DDS graphic - input is DDS - the Image magick output can't be loaded by my two dds viewers - one of them Gimp's dds.exe crashes (gimp 2.8.14): Problem signature: Problem Event Name: BEX64 Application Name: dds.exe Application Version: 0.0.0.0 ...
