touchgfx::PainterRGB565Bitmap class
@class PainterRGB565Bitmap PainterRGB565Bitmap.hpp touchgfx/widgets/canvas/PainterRGB565Bitmap.hpp A Painter that will paint using a bitmap. PainterRGB565Bitmap will take the color for a given point in the shape from a bitmap. Please be aware, the the bitmap is used by the CWR (not Shape), so any rotation you might specify for a Canvas Widget (e.g. Shape) is not applied to the bitmap as CWR is not aware of this rotation. @see AbstractPainter

Methods
setBitmap()
@fn void PainterRGB565Bitmap::setBitmap(const Bitmap& bmp); Sets a bitmap to be used when drawing the CanvasWidget. Sets a bitmap to be used when drawing the CanvasWidget. Read more...
setAlpha()
@fn void PainterRGB565Bitmap::setAlpha(uint8_t alpha); Sets an alpha value for the bitmap. Sets an alpha value for the bitmap. If the image contains an alpha channel, this alpha value is combined with the alpha in the bitmap to produce the final alpha value. Read more...
getAlpha() const
@fn uint8_t PainterRGB565Bitmap::getAlpha() const; Gets the current alpha value. Gets the current alpha value. @see setAlpha. Read more...
