Description
Origin of coordinate system to use when annotating with text or drawing.See GMImage.TransformReset to reset current transform.
Examples
Draw rectangle 45° rotated at specific coordinate:
# move origin
Set Variable [ $r ; Value: MBS( "GMImage.TransformOrigin"; $img; 50 + 125; 50 + 75 ) ]
# draw rectangle centered there
Set Variable [ $r ; Value: MBS("GMImage.DrawRectangle"; $img; -125; -75; 125; 75) // 250 x 150 ]
# rotate 45°
Set Variable [ $r ; Value: MBS( "GMImage.TransformRotation"; $img; 45 ) ]
# draw rectangle centered there
Set Variable [ $r ; Value: MBS("GMImage.DrawRectangle"; $img; -125; -75; 125; 75) // 250 x 150 ]
