How to rotate bitmap image for specific angle

[Dilanka]

Hello,

I need to create custom progress bar. So I need to know there is any method to rotate bitmap image for specific angle?

There is no image rotation support in uGFX currently. If your display supports changing orientation you can work around this by rotating the display relative to the drawing canvas instead.

Another way is to maintain multiple versions of the image pre-rotated.

Using an image that rotates constantly for a progressbar sounds like a bad idea. Usually you use pictures for backgrounds and then use the primitive rendering functions to draw on top of that. You can easily rotate shapes like polygons and similar.
