Constructor & Destructor Documentation
◆ SmoothShape()
| roo_display::SmoothShape::SmoothShape | ( | ) |
Definition at line 9 of file smooth.cpp.
Member Function Documentation
◆ 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.
◆ readColorRect()
|
overridevirtual |
Read colors for a rectangle.
Returns true if all colors are identical (then only result[0] is valid). The caller must ensure the rectangle is within bounds.
Reimplemented from roo_display::Rasterizable.
Definition at line 1888 of file smooth.cpp.

overridevirtual |
Read colors for the given points.
The caller must ensure all points are within bounds.
Implements roo_display::Rasterizable.
