IM lowers color depth when I don't want it to

I am using the following command on a 24bit input file: convert "%ImgPath%\Walls_Misc00.png" -crop 64x96+0+32! "%ImgPath%\Walls_Misc00_crop.png" However, the result is an 8bit image. How do I make it so that the image stays 24bit? Thanks! Version: ImageMagick 6.9.2-6 Q16 x64 2015-11-14 http://www.im...

ImageMagick montage always chaging from 32 bits to 8 bits

I am trying to create a montage from a series of 32 bit PNG images. However the result always gets reduced down to 8 bits with no transparency. Here's an example of one of the source images: http://imgur.com/sTQWcV3 Here's an example of my command line: montage "%ImgPath%\layer_0.png" "%ImgPath%\lay...

Re: IM ignores alpha channel and lowers bit depth

Post an image and the command line that fails. Also look at the input and output image formats to see what depth they are. My test on your earlier image, showed that both were 8/1-bit images and not 32 or 24 bit. Perhaps I misunderstand your problem. So please explain a bit more clearly. Sorry I ed...

Re: IM ignores alpha channel and lowers bit depth

See here: http://newsgroup.xnview.com/viewtopic.p ... 15#p103215

I would still like to know why this occurs only with some images and not with all, as well as a way to disable this behavior. Why is IM converting the image into a grayscale PNG instead of the full 32bit RGBA format?

leave off the -background transparent and that works fine for me on IM 6.7.6.9 Q16 Mac OSX Snow Leopard. convert IM_Effect_Smoke_problem.png -crop 64x64+0+64\! result.png I am not sure -- on windows you may need to escape the ! differently.

IM ignores alpha channel and lowers bit depth

Here's the image I'm working on: http://i421.photobucket.com/albums/pp292/SharkD2161/Support/IM_Effect_Smoke_problem.png Here's the MS_DOS command line: convert "IM_Effect_Smoke_problem.png" -background transparent -crop 64x64+0+64! "IM_Effect_Smoke_problem_crop.png" The problem is that ImageMagick ...
