Image

└ RasterImage

Base class for decoded raster images.

Raster images are decoded natively and cached by filename. The current backend supports BMP directly, uses Windows Imaging Component on Windows, and uses the platform gdk-pixbuf runtime on Linux when available for GIF, JPEG and TIFF families.

image = BmpImage("logo.bmp")
painter.drawImage(image, 16, 16, 128, 64)
