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...

4 JPGs zu einem zusammenfassen,
Rand rundrum dran machen und beschriften. Es ist mal wieder ein 1-Liner für #Bash und #Imagemagick

Google: "I see you're searching the #ImageMagick documentation again. Have you considered religion?"

i'm in the mood ..

Standard interchange image format for Open Source DTP

Hi people,

with all the mayor GUI #DTP software reaching their peak: #GIMP, #Scribus and #Inkscape; and the well established #TeX software #ConTeXt and #SpeedataPublisher, and #ImageMagick we need a serious discussion about which image format we should adopt that works seamlessly across all these applications and it is generally accepted in the press workflow, whereas is embedded or not into a PDF file.

It should be something that has good quality, supports #CMYK and Alpha channels and it is #opensource friendly and perhaps an #openstandard.

I would dare to say that perhaps jpeg2000 matches most of them, it exists from a very long time and can be adopted as common ground, however it is need a combined effort, if what I am writing makes sense for you.

ImageMagick supports it, Gimp 3 currently doesn't, #LuaTeX and #LuaMetaTeX neither. I guess that Inkscape once it will be able to export in CMYK it will decide which format using to store images in CMYK with alpha into a PDF.

It would be very beneficial if we can adopt a format that works everywhere and it is press friendly, thanks.

i would rather feel compressed ..

how to retrieve #picture #metadata in #linux
1. simpleminded:
file x.jpg
2. camera-specific:
exiftags x.jpg
3. mastermind (https://superuser.com/questions/275502/how-to-get-information-about-an-image-picture-from-the-linux-command-line) using the #ImageMagick package :
identify -verbose x.jpg

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.

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?!
