I only wish Windows had something similar. As GDI in Windows 10 probably only lives virtually in a layer of software feeding the GPU, I'm getting a strong feeling that we should gradually start looking at Direct2D as it is the MS recommended 2D graphics solution for new applications.

Yes.. Already started "looking". But need to realease first.

LineTracker is nice, will probably merge it for the next release.

Hi,

Good to hear that, thanks. Meanwhile, let's give it some time to mature. I will re-post it when it has been stable for some weeks while I'm developing it's surroundings. Please remind me if I forget about it...

Best regards,

Tom

BTW, I have just checked situation on MacOS. Current draw path is drawing 4K image in 2.5ms, so I think it is good SW implementation...

EDIT: It is more complicated. It looks like it might be HW accelerated after all...

Hi Mirek,

Sounds interesting -- despite I do not have a Mac. Just for reference, is this 2.5 ms the same for opaque and alpha images? And which Mac model did you test with?

Best regards,

Tom

Actually, it is is in microseconds range, just like X11, but it is all complicated, some results are now great, but sometimes it gets very slow, needs more investigation.

I have made some changes to RectTracker:

- Fixed the behaviour when there are some widgets in the view area
- Added TrackLine for free line endpoint tracking
- Optimized Refreshing. This probably might break some code using RectTracker as base, it might need to override RefreshRect method.
