Re: Tiling 4 different animations

I suppose each input has the same number of frames, and are the same width and height? There are many way of doing this. You could create enough single-colour frames, all the same size, width and height large enough for the four inputs. Add a "null:" image, then all the frames from the first mp4, an...

Re: Compare no output

For IM v6, either use the "compare" command, or "convert" with the "-compare" option. compare -metric AE 1586348746.png 1586348789.png output.png convert 1586348746.png 1586348789.png -metric AE -compare -format %[distortion] +write info: output.png I don't think there is any method to always guaran...

Re: Compare no output

What version of IM? If v7, I suggest you use "magick", not "convert". You seem to be confusing two possibilities. 1. Use "magick compare". Note there is no "-" in compare. For example: magick compare -metric AE 1586348746.png 1586348789.png output.png The text goes to stderr. 2. Use just "magick", w...

Re: Change single color to another in image

What is your platform: bash, Windows BAT, or whatever? If Windows BAT, you need to double the percent % signs to %%. As you use IM v7, I suggest you use "magick", not "convert". Please show the text output from "magick -version". If you use Q16 or larger, the final operation probably needs a fuzz. "...

Re: EvaluateOperator

I'm not sure what you are asking. Where did that code come from? I suppose the code you show wouldn't compile because I don't think "IMagickImage" is a valid type. Aside from that, "what this piece of code is doing" should be clear from the code. It reads an image from a file, then adds it to a list...

Re: Change single color to another in image

What version of IM?

Your input is grayscale, so I suggest inserting "-colorspace sRGB" after reading the input.

Re: png with wrong palette

Your *.bytes file are actually PNG files. I suggest you use the PNG extension. IM does not have methods for directly manipulating palettes. Gimp does, and may be better for your purposes. Your pic256_0.bytes has useful values in the red and alpha channels. Perhaps you want to use the red values as a...

Re: About "convert: no pixels defined in cache " error

Your command starts with "-rotate 180". But you haven't read any images yet. You should read at least one image, then rotate it.

You may need "-layers coalesce" immediately after reading the gif, not many steps later.

Re: How compose two or three jpg files to one new file

Yes. Decide what you want for the output, RGB or CMYK, and change one of the inputs to match the other.

Re: identify on vector pdf

IM delegates rasterization of PDFs to Ghostscript. If this fails, eg because a script inside docker can't access GS, then IM will write a message to stderr and then exit(1).

The "-verbose" setting will also helpful information write to stdout.

Re: Clipping results in empty image on CentOS

imagick.exe convert ... Is that really your command, with "i" at the start? Perhaps your command was "magick.exe convert". For v7, I suggest you use just "magick". Not "magick convert", and not "convert". When your command has "-clip", I suggest it should always also have "+clip", to turn clipping ...

Re: EPS input, PNG output: no clip path defined with 7.0.10

With the latest input.eps linked upthread, with Ghostscript 9.19, IM v6.9.9-50 shows a clipping path but IM v7.0.8-64 doesn't.

Perhaps IM v7.0.8-64 has a bug.
