I can't reproduce the error in a short code; the code I use is approx. 1500 lines long (an incomplete terminal emulator).
Code: Select all
Img=CreateImage(-1,100,100)
Debug img ; returns a number
Debug IsImage(img) ; returns zero
StartDrawing(ImageOutput(Img)) ; fails / IMA
The image is apparently created, the first debug returns a number. But something does not work right and IsImage(img) returns zero.
I use OpenWindowedScreen() in the executables/demo codes, so maybe this could be linked, but in a short code it doesn't cause an error.

Why do you post this question in the bug section, if you can't reproduce the error in a short code?
How should we reproduce the possible issue?
Where do you think the bug should be?
If IsImage(img) is null, then img is (no more) valid image number.
This could happen, when e.g. the image was freed.

Maybe it is related to the other bug involving #PB_Any (=-1).

That's what I wanted to point out.
#PB_Any is '-1' and therefore dynamic PB objects are created. Do not use '-1' but #PB_Any to avoid confusion.
See PB-Help

Just asking because most of us already have forgotten this at one point: Is "Img" an integer?

Img must be a integer because its an pointer to memory array

Can you try to narrow down the IMA with
x64dbg or
OnErrorGoto(address, triggering command, register, stack and everything including the last MOV dword [CLN],nn)
