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.

Just for fun I'm writing an #ILBM impl. for #Qt (QImageIOPlugin). I'm having trouble with the PCHG chunk. Any #Amiga dev/hobbyist here who might have a clue what's wrong? My code:
parsing: https://github.com/panzi/qilbm/blob/4222c4bdf5b81ab67fc68b3647ca231d1685d53a/src/ILBM.cpp#L865-L1097
rendering: https://github.com/panzi/qilbm/blob/4222c4bdf5b81ab67fc68b3647ca231d1685d53a/src/ILBM.cpp#L1297-L1346
sample file: https://sembiance.com/fileFormatSamples/image/iffILBM/pchgcmp.iff
Other impl. I've looked at and can't finde the difference to:
https://aminet.net/package/dev/misc/PCHGLib14 (includes 2 images that *do* work)
https://fossies.org/linux/netpbm/converter/ppm/ilbmtoppm.c line 1596 and onward, which is used by #ImageMagick. #RetroComputing

+ #inkscape cli (https://inkscape.org/doc/inkscape-man.html) to render to #png
+ #imagemagick to tile and convert to #pdf
then a bunch of trial and error to figure out the right invocations, i guess

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.

I just came across this question I asked 13 years ago about pixelating images using the command line
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.
Graphic Design Stack ExchangeHow can I pixelate an image via the command line on LinuxIs there a command-line utility for Linux that can pixelate an image by a specified percentage eg "-pixelate 30%"
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?!

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

@dewomser #imagemagick ist schon lässig. Will das Kind beurlauben lassen. Die App ihrer Schule will nur Bild-Dateien für eine Bescheinigung, habe allerdings ein PDF. Mit einem Einzeiler fix konvertiert!
#Linux #Bash
Die Screenshots für die Skripte hab ich immer mit "import" gemacht. Das gehört zu #imagemagick, funktioniert aber mit Wayland nicht mehr 
Nachbau für #KDE mit "spectacle" tut genauso und sieht täuschend ähnlich aus. 
spectacle -r -n -b -d 5000 -o foo.jpg
