how to get a canvas from Image or Bitmap

[WuSanxiao]

i have not found a Api to to get a canvas from Image or Bitmap

[WuSanxiao]

another confusion what is the differences between Bitmap, Image, Picture and Pixmap?

[tonsky]

Canvas has ctor that accepts Bitmap. The difference is:

• Bitmap is mutable byte array you can draw into
• Image is “GPU texture”, ready to be drawn, but not changed
• Picture is “recording of commands”, so it can be reproduced, but has no direct pixel data at all
• Pixmap, I think, is something that holds pixels for Bitmap
