Re: Installed ImageMagick But no delegates

What is your platform/OS? You can install binaries that include most if not all the needed delegates. See https://imagemagick.org/script/download.php

Re: Pull my .gif into an exe - or rather, multiple gifs to rid green screen...

I have a greenscreen script, but it is for Unix-like systems and does not run under normal Windows. You would have to use it on Windows 10 Unix or Windows w/Cygwin. But it runs on a single image and not an animation.

Re: Pull my .gif into an exe - or rather, multiple gifs to rid green screen...

What is your ImageMagick version and platform?

Which green screen script?

If it is my greenscreen script at my link below, then you cannot. My scripts are bash shell scripts and do not run on Windows as .bat scripts.

Re: vertical stripes in a resized image

They are the delegates for PNG and JPEG. Image magick use them for reading/writing those formats. If they are old, they could be buggy or incompatible. As for Windows ImageMagick, sorry, I mistyped. I was testing on 7.0.10.2, which is indeed the current version.

Re: vertical stripes in a resized image

It works fine for me on IM 7.0.11.2 Q16 Mac OSX. Perhaps try upgrading. Also what are your versions of libpng and libjpeg?

Re: Problem with removing the background by clipping path

I am not sure I know what you expect. It looks like each layer has a its own clip path when looking at the verbose information. So just loop over each layer and remove the clip path and then merge the results. Unix syntax for IM 7 num_layers=`magick convert rechteck2.psd -format "%n\n" info: | head ...

Re: potential bug -resize IM 6.9.11.2 and IM 7.0.10.2 Q16 Mac OSX Sierra

OK. Thanks. That is what I suspected. But why is -channel sync not working for me on my Mac IM 6.9.11.2 or 7.0.10.2?

That does not work. I also tried -channel rgba and it does not work. convert in.png -channel sync -resize 50% in2.png convert in2.png -alpha off aoff2.png aoff.png does not keep the colored circles. I note that the image is not rgba(0,0,0,0) at the pixels that have color under the transparency in th...

potential bug -resize IM 6.9.11.2 and IM 7.0.10.2 Q16 Mac OSX Sierra

When resizing an image with transparency, the background region in the underlying rgb channels is set to black. In the following image, there are 3 colored circles in the lower left quadrant in the original that are under full transparency. When the image is resized by 50%, those 3 colored circles a...

Re: Multicrop with CMYK tiff

You can convert to RGB, process, then convert back to CMYK. Perhaps you can do your processing in CMYK with -connected-components, which is what I use in my script. All you need to do is convert your image to binary where the images are white and the background is black. Then process that image with...

Re: Reduce canvas size non-destructively

Your input in you command is a PNG. It does not have layer information. Did you mean PSD?

ImageMagick is limited in what it can do with PSD files.
