Hello.
Point(x,y) returns right color under Windows, but wrong color under Linux and Mac OS
From same source - under Windows I got C0C0C0 color ,under Linux - 3C0000.
x,y coordinates is doesn't matter.
Best Wishes.

Hello dibor
Windows defaults to RGB format. Perhaps Linux and MAC are using a different format/colour space?
Edit: Apple's own colour picker has issues (or at least confusion):

Hi.
Tnx for answer.
I am do not care about color formats.
Compiler mast to care.
Point function supported by ALL OS's, so I do not need to do any manipulation for getting pixel color in any OS
Code: Select all
If StartDrawing(WindowOutput(#Window_MainWindow)) ;
WinBackColor = Point(0,0)
Debug WinBackColor
StopDrawing()
EndIf
May be I am wrong or do not understand something

in this case ... you have to "eat" all events on Linux and Mac, if this "GetWindowColor" is directly after Windowcreation !
Only after the events from the creation process are done, you can read the color. On windows you don't need it, but on the other os.
Code: Select all
While WindowEvent() : Wend
If StartDrawing(WindowOutput(#Window_MainWindow)) ;
WinBackColor = Point(0,0)
Debug WinBackColor
StopDrawing()
EndIf

That's not what Bisonte wrote.
On Linux and OSX you have to wait until the window creation is complete before you can read the color.
So you have to add a short delay and wait until all (first) window events are finished, like Bisonte wrote in his example.

@dibor: No problem. But in the future you should always have bugs confirmed by others before posting them in the bug forum.
