Hi all,
in one of my libraries I wrote I've this line:
B4X:
... where W and H are 200 pixels.
The image I process is a big horizontal stripped image of 20000x200 pixels where I just use a portion 200x200 on it, in the case of this line I've posted it just draw the first frame because the sourceX is zero, to show all frames I just increase the StartX every 200 pixels, so 200 show a second frame, 400 the third frame and so....
This always worked on old system with Win XP but still return a null pointer exception on a new system with Win 11.
In new system I compile with Java11, on old system I compile with Java8, maybe is this the problem ?
I even add #VirtualMachineArgs: -Xms256m -Xmx1024m so is not a memory Heap problem, the full image is 570Kb in jpg format or 2.8Mb in png format.
I tried to reproduce it with a small code and have the same issue, with smaller images (in pixels) works, with larger images (in pixels) does not works...
