Perhaps you are running out of space in your tmp directory. Look to see if it is filled with images that did not get deleted, esp. those belonging to Imagemagick.
Imagemagick 6 cannot currently handle that many channels. It only currently saves up to 5: C,M,Y,K,A in an external format. Imagemagick 7 can handle up to about 30, I believe, but only in internal format files.
You can write the images into a montage image grid.
Here is another interesting example -- see my Imagemagick solution for trimming and appending fisheye stereo pairs side-by-side at https://stackoverflow.com/questions/58349762/cropping-to-only-valid-pixels-after-remap-with-fisheye-equidistant-stereo-rect Note a new argument for the aggressive -trim ...
I can create a montage of animations and it will animate using the latest beta (IM 6.9.10.69 or IM 7.0.8.69). If they have different numbers of frames, an empty spot will appear. So it should be easy for you to create your contact sheet of animations. Just make the tiling correspond to the number of...
You have two other options. First, Imagemagick has a built in MSVG/XML renderer. You can see that if you do convert -list format look at the line for SVG. At the end, it should list MSVG or XML The other option is just to install Inkscape. Then Imagemagick will use it if it can be found. You do not ...
Montage seems to work to create a montage of animations, but it does not seem to permit the use of -delay. Can that be added? This works and the result is an animated gif of the 4 animated gifs. montage anim.gif anim.gif anim.gif anim.gif -tile 2x2 anim4_montage.gif But this does not work: montage -...
Your first line [/etc/config/ImageMagick-6] # convert -debug all /opt/fhem/www/images/Kindle_Status.svg -type GrayScale -depth 8 Seems to be missing an output. It also looks like you are trying to convert an SVG to PNG and not PNG to SVG. Please clarify. Perhaps post your exact command line. The lin...
The latter. I want to make an animated contact sheet from many animated gifs. The problem with that is that you need to sync the animations. That generally only works well if you have the same number of frames and the same delays in all the animations. See https://imagemagick.org/Usage/anim_mods/#m...
Are you asking to take one animated gif and extract all the frames and make a contact sheet of those? Or are you asking to make an animated contact sheet from many animated gifs?
One potential way is notch filtering via FFT processing. See http://www.fmwconcepts.com/imagemagick/fourier_transforms/fourier.html#noise_removal Another way, might be to simply create a mask image that is black where the checkerboard does not exist and white where it does. Then use the mask to repl...
The listing from connected components when you use verbose=true in the define will show all the bounding boxes. So you just need to parse the output to get them. Once you have them, you can use -crop with those bounding boxes to extract each image one at a time. You will have to script these parts.
There is no -define jpeg:size. There is a -define jpeg: extent={size} where size is in kb. See https://imagemagick.org/Usage/formats/#jpg_write. Also add -density XX before reading the pdf to get better quality. convert -density 300 <path to EPS file> -thumbnail 319x319 -define jpeg:extent={size} cq...
