I need to draw rotated rectangle on Canvas.
I have x and y of top left rectangle corner and angle of rotation around that corner.
If I use context.rotate() function it will rotate canvas around (0,0).
Is it possible to rotate canvas around custom center on GWT?
Yes, use
context.translatefirst to change the origin, thus changing the “center” of rotation. (since all rotation is done about the origin). Typically you’ll want totranslateback the same amount afterwards.
