Always use a lossless format such as tiff or miff or png.
Please don't recommend PNG as an intermediate format, it cannot handle CMYK. Even when that's not important here, other users might get into trouble :-)

Re: IM7: subimage specification returns no images

Thanks for your reply. Are you sure you have 64 images? No, more than 64. That's why I'm not using an asterisk for globbing. If so, the indices should be [0-63] if you want all of them. No, it starts at "..._0001.png" What is your OS? Microsoft Windows 7 Professional, 64-bit (Version 6.1.7601) This ...

IM7: subimage specification returns no images

Hi there, this has worked for years in IM6, I've changed montage to magick montage for IM7: magick montage "02_%04d.png[1-63]" -tile 9x7 -geometry 256x256+0+0 test.png But now I'm getting tons of these: magick: subimage specification returns no images `02_0030.png' @ error/constitute.c/ReadImage/637...

Re: -region not working

Sorry, didn't want to sound vulgar. "RTFM" is a fixed term and never meant vulgar. It's even part of modern dictionaries: http://www.dictionary.com/browse/rtfm

Actually, I just wanted to make a joke, since everyone says: RTFM ... "RTM" sounds like "ready to manufacture", which also is a fixed term.

Re: trim & make transparent (region)

Your syntax is not truly proper though IM 6 is forgiving. You should read your input first, then settings, then operators, then the output: Sorry, didn't know the syntax changed.

I do not understand why you are doing a -resize 75% inside the region command. Can you explain? What are you trying to resize -- just the region or the whole image?
Because I've RTFM and it's an example in there :) http://www.imagemagick.org/Usage/maskin ... _internals

trim & make transparent (region)

Hi there, I want to trim an image by a fuzzy border color (white to gray) and make the old border transparent. Works fine with this: convert -fuzz 50% -trim input.png -background transparent -flatten output.png Now I'd like to take 10% from "-gravity north" and also want to turn the white color to t...

Re: CMYK to sRGB: issue with profiles

Maybe I also should try the tools from ArgyllCMS. They might have better profile handling?

Re: JPEG: issue with sampling-factor

You are getting 2x2 because that is the default value for YCbCrSubSampling. The next version of ImageMagick will only show the jpeg:sampling-factor when it was stored in your file. This means that you will no longer see it with the command from your initial post in the next version. Thanks for your...

Re: JPEG: issue with sampling-factor

The issue is that the sampling factor will only be stored when the colorspace is YCbCr. The sampling factor is stored in the following tiff tag: http://www.awaresystems.be/imaging/tiff/tifftags/ycbcrsubsampling.html. I also found the following in the code of libtiff: But doesn't this default to 1x1...
