#imagemagick

Just received a funky PDF file that #ImageMagick does not like.
‘identify it.pdf’ thinks for three seconds and tells me it’s a 3000x1980px CMYK in .AI format.
‘identify -verbose it.pdf’ has been spinning without any output for 20 minutes, eating 100% of one CPU core.

Even if I could figure out what’s bricking it, I wonder what the hell I can do about it.

Can't Remove from App Menu #softwareinstallation #imagemagick

@AbramKedge @Goffi
I'm a bit surprised #gimp doesn't have a plugin for the, because essentially the code required is just looking for a predefined border (and maybe an expectation of how many bordered regions to find).

#imagemagick probably does the job though.

Is there any way to share an image to a shell script from within Android, or even just copy the full path of a file with an Android?

The thing is I'm using Image Toolbox to perform my #LossyPNG conversions on the go, but I find that #imagemagick convert actually does a far better job at choosing colors than Image Toolbox does.

There just isn't a convenient way (that I've found so far) to grab the full path and filename of an image from the gallery and then share that with a shell script running in #Termux.

Hat schon mal jemand mit #imagemagick ein Bild von einem digitalen Display für #tesseract OCR aufbereitet? Wie sähe eine näherungsweise sauber arbeitende Zeile für #convert hinsichtlich Schärfung, Kontrastverbesserung und Graustufenkonversion aus? Retoot gerne gesehen.

JPEG 2000 (+25)

I am still wrapping my head around #jpeg2000...

It looks like #Gimp 3 removed the exporting support for it...

I can still use #imagemagick to trigger the conversion from any source to jpeg2000 to PDF.

But fewer steps are better...

Maybe I should just make turning GifCities gifs into Minesweeper maps my "thing". Would be a lot less expensive than eurorack that's for sure. #creativecoding #imagemagick #ffmpeg

I used my newfound skills to update a bash script I wrote 13 years ago to make animations like this.

#ffmpeg #imagemagick #generativeart #animation

I just came across this question I asked 13 years ago about pixelating images using the command line

https://graphicdesign.stackexchange.com/questions/8422/how-can-i-pixelate-an-image-via-the-command-line-on-linux

That method of downscaling then upscaling to produce pixelation was acceptable at the time but the problem is that you couldn't easily specify the size of the "big pixels"

Searching again in 2025 and it looks like ffmpeg has had a pixelation filter since 2022 and can be used like this:

ffmpeg -i input.mp4 -vf pixelize=40:40 output.mp4

So now I'm using ffmpeg, a video editor, to pixelate images.

#ffmpeg #imagemagick

It's so funny to see how

find . -name "*.jpg" -exec mogrify -format png {} \;

"unchungifies" 10MB of 100% Quality "lossy" JPEG into 50MB of 100% Quality "lossless" PNG...

Aint it supposed to be the other way around?!
#linux #imagemagick

@mcc #ImageMagick has a Windows binary distribution.

https://imagemagick.org/script/download.php#windows

#PDF is among its supported formats.

https://imagemagick.org/script/formats.php#supported

You can use its convert utility to combine multiple images into a single PDF.
