I don't see any 6.6.6.3 release unless it is beta. I got it from http://www.imagemagick.org/script/binary-releases.php#windows today. It is mislabeled. 6.6.6.3 results (39321 0.6) look correct Please see 6.6.6.3 result (0 0.6) I suspect the other results are from difference in older versions where ...

The solution in my head seemingly differs from Anthony's, but here is my try:

convert book*_picture.jpg null: branding_file.png -layers composite book%%d_picture_stamped.jpg

Maybe this is caused by trying something I wasn't supposed to. I have reproduced it using two recent versions. > convert -version Version: ImageMagick 6.6.5-8 2010-11-10 Q16 http://www.imagemagick.org Copyright: Copyright (C) 1999-2010 ImageMagick Studio LLC Features: OpenMP > convert -size 100x256 ...

Thank you, scripting outside of IM is certainly one solution. -fx maxima is one too (but very slow). My original try didn't give an error so I just wondered if I was close. My try did result in some unexpected behavior, so my curiosity increased.

I have tried using %[max]. I have also tried a -set option: arrangement.

The solution wouldn't have to involve -evaluate, it was just the only idea I had.

What is the difference between %[max] and %[fx:maxima]?

I can limit the area affected by the -composite operation using a mask: http://www.imagemagick.org/Usage/compose/#mask Can this be done for other operations? I have been looking with no luck so I'm guessing not. I want to modify a small part of a larger image, say using -blur or -fx. Right now I'm o...

I would like to set every pixel in an entire image to the image's maximum (or minimum, etc.) value. I tried: convert -size 100x256 gradient:#000-#999 in.png convert in.png -evaluate Set %[fx:maxima] out.png convert in.png -format %[fx:maxima] info: --- 0.6 convert out.png -format %[fx:maxima] info: ...

As for your second need, inputting and outputting multiple files, using * or ? works like one would expect.

The -composite command will work for combining images.

This task should be reasonably easy.

As usual, fmw42 has the simplest implementation. Using your cube mapping: convert -size 10x512 gradient:black-white -rotate -90 test_image.png convert -size 1x64 gradient:#000-#f00 gradient:#f00-#ff0 gradient:#ff0-#fff gradient:#fff-#0ff gradient:#0ff-#00f gradient:#00f-#000 -append lut.png convert ...

I don't have a specific solution, but see if -limit helps.

Your ideas may best be tested on a simple gradient like convert -size 10x1024 gradient:black-white gradient.png If your image is huge, -fx can be slow. Smaller test images can be quicker for that trial-and-error development process. Once you are generating what you want, someone can help you speed i...

Sorry, I think we are talking past each other by posting too quickly. Of course you can fit 16-bit grayscale (2^16 = 64 Ki levels) into 8-bit RGB (2^(8*3) = 16384 Ki levels), but not in a way that helps you visualize anything. That cube idea would give you 10-bit by tracing 4 sides of an 8-bit cube....

Either I missed that last line or it was an edit. Do you want alternative ideas or how to accomplish a particular idea? First off, you can never really see 16-bit depth visually. Your monitor can't do it even if your eye could. Your idea will get you visualizing more than 8-bit for sure. Alternative...
