Otherwise, if you actually need to have a rotated version of the image, I would set a Matrix transformation over a new TBitmap and then use TCanvas.DrawBitmap.
It depends on the actual style you are using. For tint-enabled styles (i.e. the Android platform style) you may want to use the TintColor property of TButton.
For other scenarios (styles) you may need to edit the style of your button. For bitmap styles this basically means you need to change the portion of bitmap used to render background. For vector styles you may want to change some Color property (Fill.Color) of the element implementing the background of the button.
Have you considered rotating the whole TImage component by setting its RotationAngle property?
