#LinuxMobile Played a bit with example of #GTK4 tutorial and #Cairo, to have a light/ basic drawing/note application on my #LinuxPhone.
8 colours (Oric/Spectrum style KRGBCMYW palette) until a palette definition tool
2 modes: dynamic (tested several possibilities, made this one for the demo) or uniform line (need to add a thickness setting).
no save or anything, it’s like a Télécran (english name:”Etch A Sketch“）for now. It’s pure compiled C, and very simple, code, but it is already really slow, far under the capabilities of the device. Don’t know why for. Maybe linked to screen event? It is very smooth on my 10+ years old desktop computer.

@popolon I think trying it on a faster and more up to date phone will help the speed. The PinePhone is slow at everything.
@carbonatedcaffeine I use a PinePhone Pro, not a Pinephone, that isn’t slow at all. There are 6 64bits cores, a powerfull Mali GPU, far more powerful, than phone from between 10 and 5 years ago, that was already able to do this kind of stuff or complex 3d games. There are bottlenecks to remove here.
@popolon it's still dated hardware (2016). That was 6 years ago!
@carbonatedcaffeine So he can render at least at the speed from 10 times ago hardware, and probably at the speed of 5~6times ago hardware, it was on the top of ARM chips at this time.
@carbonatedcaffeine I Noticed by a htop, than, between the fact that #Cairo doesn’t use hardware acceleration, it is also mono-threaded, beside, probably wrong usage on my side, as a beginner in this toolkit, this doesn’t help either. This is still a high quality and fast renderer (and still very useful for output to SVG/PDF.
@popolon maybe a new solution is needed then.
