Rotating using specific commands?

[PhatPeterParticipant]

Say I want to use the canvas.DrawRect() command instead of the Draw commands that include a rotation parameter, how would I be able to rotate a sprite 90 degrees?

I am definitely not an expert here, but maybe this helps if no one else is posting. I looked into how it was done in DrawImage()

Method DrawImage( image:Image,tx:Float,ty:Float,rz:Float,sx:Float,sy:Float ) Local matrix:=Matrix Matrix=matrix.Translate( tx,ty ).Rotate( rz ).Scale( sx,sy ) DrawImage( image,0,0 ) Matrix=matrix End

Method DrawImage( image:Image,tx:Float,ty:Float,rz:Float,sx:Float,sy:Float ) Local matrix:=Matrix Matrix=matrix.Translate( tx,ty ).Rotate( rz ).Scale( sx,sy ) DrawImage( image,0,0 ) Matrix=matrix End

this is something similar to Pushmatrix, then translate and rotate and draw, then Popmatrix to get back to normal drawing.

Thanks, that got me lots of clues I got put together a general routine (not optimized or anything but to get started).
I still wonder though if Mojo has better streamlined solution for this or if you need to go OpenGLES2 for yourself to optimise things.
