Detailed Description
This interface defines a Bitmap canvas object.
Consider this object part of the view, and not of the model data, as this bitmap can only be painted on its parent canvas

◆ drawAlphaModulated()
|
pure virtual |
Render to parent canvas, with global alpha.
This method renders the content to the parent canvas, i.e. the canvas this object was constructed for.
- Parameters
-
nAlphaModulation Global alpha value, with which each pixel alpha value gets multiplied. For a normal, opaque bitmap, this will make the bitmap appear transparent with the given alpha value (value must be in the range [0,1]).
Implemented in cppcanvas::internal::ImplBitmap.
◆ getBitmapCanvas()
|
pure virtual |
Implemented in cppcanvas::internal::ImplBitmap.
◆ getUNOBitmap()
|
pure virtual |
Implemented in cppcanvas::internal::ImplBitmap.
