Some of this SORT OF exists in iOS Photos, but I was wondering if there is an iPhone photo editing app that does the following:

Create a copy of an image.

Allows one to choose a white point and a black point.

Can break an image into its primary color layers either
an RGB model or
CMYK model,
that would allow for discarding any of those layers.

That’s it. That is all I want or need from it.

Is there an iPhone photo editing app with these features?

The road to QGIS 4 is open ! The #QGIS Roadmap for the next major version is now official ! https://blog.qgis.org/2025/04/17/qgis-is-moving-to-qt6-and-launching-qgis-4-0/

The migration to Qt6 is almost complete and will enable QGIS to improve significantly. The #CMYK mode will namely be fully available.

As for releases, QGIS 3.40 LTR will be supported until may 2026. QGIS 4.2 will be the next official LTR in February 2026.

Migration work will be required for plugins, we are working on tools and docs.

I know there are some plugins for @GIMP@floss.social - but what is the reason that @gimp@lemmy.world has in 2025 still no possibility to offer RGB to CMYK options?

I don't understand why some print shops ask for sRGB source documents *without* providing a gamut limiting icc profile so you can see what the hell you are doing.

I get taking in sRGB files for non-vector printing. But without that gamut limiter you're guessing what kind of gamut narrowing will happen so you should still have access to an icc profile.

At least, in my opinion as a self-made expert

It might have taken an ungodly amount of time. But getting these corner cases right in this PDF export is going to mean the world to a lot of people.

Arabic and Hebrew and non messing up the glyphs.

#AskFedi is there a #CMYK parody of #YMCA (the #VillagePeople song)?

Viva CMYK!

This week's #inkscape video is a comprehensive look at all the features I've managed to do in Inkscape these past few weeks: https://youtu.be/iEp-ydPy2EA

Let me know if I missed anything.

Big thanks to all my sponsors on libre pay and elsewhere https://en.liberapay.com/doctormo/

Traditionell wählt Pantone zum Jahresende eine "Farbe des Jahres". Nie fiel die Wahl passender zum Zeitgeist aus, als dieses Jahr 2024. The winner is: Braun
Wer nicht weiß, wer oder was Pantone ist. Eine Firma die glaubt, die Farben erfunden zu haben und sie deswegen lizenzieren zu dürfen.

P.S.: Übrigens gibt es politisch auch Blau mit einem roten Kackstreifen, und es bleibt trotzdem deutlich Braun.

This week's #inkscape video is ready and all about doing the CapyPDF work: https://www.youtube.com/watch?v=-ji0-ccKfcA

It's late, but I'm not apologising health related delays, etc, etc.
