My current work around: Use ffmpeg to create separate animations for each image series and then stack the animations using ffmpeg again. Any advice regards where my thinking is wrong is very much appreciated. EDITED TO ADD: Apparently I misunderstood the question, so I edited out my previous answer...

After more testing I realized that I can't entirely drop the black channel from the CYMK separation. [...] To my novice eyes, adding a second +clone line and fuzzing the K-channel to a few percentage points of #000000 would work, but I'm not sure how to pull that off and then combine both into the ...

The blocks are white (FFFFFF) for example, in reality, I'll use different colors, but for simplicity, I'm using FFFFFF here. I need the first and second block to only print 1 and 2 respectively without having other numbers written on top. When using "-annotate" you can include FX expressi...

montage sucks because it requires I have 9 identical files in the working directory, so my script generates them and then deletes them after the montage command. The other solutions offered above are good. Here's another pretty simple idea to make a 3x3 tiled result from a single input image... con...

Thanks. I noticed that and was editing probably as you were replying.

I've been hitting the google books and am trying to figure out how to remove all shades of grey from an image. (ie preserve all "colors") There are several ways to approach this, and some very good solutions have already been provided. I worked from a slightly different direction. This us...

I was trying to use: magick composite "pattern.png" -compose Multiply "green.png" "mrp3.png" what is wrong for RGB channels, only alpha channel has correct A amount, than I tested if it would work for only grayscale and for only one channel( R ) and it worked, as expec...

Is it possible to use percent escapes with the -extent option? I would like to swap the width and height of an image, but keep everything else the same. As mentioned, the FX expressions are most versatile using IM7, but it can be done with IM6 using "-distort" and setting a viewport. Try ...

im trying to combine this two command into one but i dont know for generate one image instead of two image result convert fragresultc.png -fill white +opaque "$zv" -negate resuxxlt.png convert image2.png -mask resuxxlt.png -fill white +opaque white +mask rose_blue.png At the place in the ...

There are many tools . You're probably trying to: magick convert source_filename.tif -resize 27071x18702! new_filename.tif Unless there is a specific need to emulate the behavior of IM version 6 you should not use "magick convert". Just use "magick" for IM version 7 to take adva...

But now I have to get an information about image to the info.txt. I am trying to write something like this: start C:\ImageMagick\magick.exe -format "%wx%h" >d:\info.txt d:\Image.jpg The file d:\info.txt is overwritten, but there is no data. With IM version 7 you need to put the input imag...

Typically you might need +repage for commands that change the image size, such as rotation, distortion, and especially crop and trim. I do not think resize needs it. At least I have never needed it for that kind of operation. Also -layers merge needs it. I also usually do a "+repage" afte...

Landscape: 1.91:1 Portrait: 4:5 Can I tell IM to crop only if the image is beyond these aspect ratios? You should always include the version of IM you're using and which platform you're running it on. With most recent versions you can crop to a particular aspect ratio using "-extent" like...

Just curious if anyone knows if there is a straight forward way of flipping that? So the sky is on the inside and the land on the outside? Rotate the image 180 degrees before the "-distort arc". Then you rotate it back the other way by adding a second argument to the "-distort arc&qu...

ImageMagick 7.0.8-36 Q16 x64 HDRI on Windows 10. This command produces no output image, no warnings, and no errors... magick wizard: -virtual-pixel mirror ^ -distort affine "0,640 0,640 480,640 480,640 0,0 480,0" wizard.png Changing the virtual-pixel setting to anything other than "mi...
