Re: scripts library load error (macOS)

What is your exact Imagemagick 7 version? How did you install it?

What do you get from

Code: Select all

magick -version
Does your input Tiff have more than one page or layer. The script can only process one page or layer, so use ABC.tif[0]

Re: Export layers to individual psd file keeping guides

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.

Re: Potentially hundreds of images in an animated frame sequence

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.

Re: Create an animated "contact sheet" of gifs

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...

Re: Please add -delay to montage

It works in IM 7.0.8.69 beta. Thanks. See https://imagemagick.org/discourse-serve ... 86#p169596

Sorry, I forgot to check, but can you also add -layers optimize to montage? Thanks

Re: Converting SVG to PNG on QNAP fails

It should run automatically when you do

Code: Select all

convert image.svg image.png
But your delegates do not have xml installed.

Can you install Inkscape on the system, which does not work as a delegate. So IM does not need to be reinstalled.

Re: Converting SVG to PNG on QNAP fails

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 ...

Please add -delay to montage

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 -...

Re: Converting SVG to PNG on QNAP fails

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...

Re: Create an animated "contact sheet" of gifs

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...

Re: Create an animated "contact sheet" of gifs

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?

Re: Removing "checks" dithering

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...

Re: Detecting multiple images in one image file

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.
