◆ anchorExtents()
|
inlineoverridevirtual |
Return the bounds used for alignment.
Defaults to extents(). Some drawables (notably text labels) may want different alignment bounds.
This method is called during a transaction and must not block or perform I/O.
Reimplemented from roo_display::Drawable.
Definition at line 566 of file smooth_transformation.h.
◆ extents()
|
inlineoverridevirtual |
Return the bounding box encompassing all pixels that need to be drawn.
This method is called during a transaction and must not block or perform I/O.
Implements roo_display::Drawable.
Definition at line 565 of file smooth_transformation.h.
◆ readColors()
|
inlineoverridevirtual |
Read colors for the given points.
The caller must ensure all points are within bounds.
Implements roo_display::Rasterizable.
