RotateBrush() may destroy hardwarebrush

There are two display height sized brushes. The first is created horizontally and then rotated, the second is created in the same size as the other after 90 degree rotation.
The rotated brush does not displayed on the GLGalore display.
Tested on OS4 and MOS and the results are the same.
Here is a test script.
Code: Select all
@REQUIRE "glgalore.hwp"
@DISPLAY {mode="windowed", title="test", borderless=False, width=800, height=600, nomodeswitch=False}
CreateBrush(101,600,120,#RED,{hardware=True})
CreateBrush(100,120,600,#RED,{hardware=True})
RotateBrush(101,0)
BeginDoubleBuffer(True)
game={
scroll = 0,
}
Function p_draw()
Cls
game.scroll=Wrap(game.scroll-1,0,600)
DisplayBrush(101,384,game.scroll)
DisplayBrush(101,384,game.scroll-599)
DisplayBrush(100,84,game.scroll)
DisplayBrush(100,84,game.scroll-599)
Flip
EndFunction
SetInterval(1,p_draw,1000/60)
Repeat
CheckEvent
Forever

Can you test on Windows as well?

Yes, testing in a minute!
Until then let me show you an even hair-raising case!
When the rotated brush displayed with {scalex=0.5, scaley=0.5} it is shown unrotated.
Code: Select all
@REQUIRE "glgalore.hwp"
@DISPLAY {mode="windowed", title="test", borderless=False, width=800, height=600, nomodeswitch=False}
CreateBrush(1,100,100,#RED,{hardware=False})
SelectBrush(1)
TextOut(#CENTER,#CENTER,"DEADBEEF")
EndSelect
CopyBrush(1,100,{hardware=True})
CopyBrush(1,101,{hardware=True})
RotateBrush(101,90)
BeginDoubleBuffer(True)
game={
scroll = 0,
}
Function p_draw()
Cls
game.scroll=Wrap(game.scroll-1,0,600)
DisplayBrush(101,384,game.scroll,{scalex=0.5,scaley=0.5})
DisplayBrush(101,384,game.scroll-599,{scalex=0.5,scaley=0.5})
DisplayBrush(101,584,game.scroll)
DisplayBrush(101,584,game.scroll-599)
DisplayBrush(100,84,game.scroll)
DisplayBrush(100,84,game.scroll-599)
Flip
EndFunction
SetInterval(1,p_draw,1000/60)
Repeat
CheckEvent
Forever

On windows they all works as expected.
For a clarification to the first example the rotate line should be: RotateBrush(101,0).

Well, if it works on Windows chances are that those are bugs/limitations in MiniGL and TinyGL because the code is the same. I'll investigate when I have some time but all GL Galore issues that don't happen on Windows/macOS/Linux don't have a high priority because MiniGL and TinyGL have lots of limitations of course
