AbstractPainterColor
touchgfx/widgets/canvas/AbstractPainterColor.hpp
An abstract class for creating painter classes for drawing canvas widgets. All canvas widgets need a painter to fill the shape drawn with a CanvasWidgetRenderer. The painter must provide the color of a pixel on a given coordinate, which will the be blended into the framebuffer depending on the position of the canvas widget and the transparency of the given pixel.
The AbstractPainter also implements a function which will blend each pixel in a scanline snippet into the framebuffer, but for better performance, the function should be reimplemented in each painter.
