Bitmap pixel value interpretation modes. More...

Detailed Description

BitmapFormat::ARGB32	AARRGGBB format. The alpha AA component is used to represent the transparency of each pìxel: from 0=transparent to 0xFF=opaque. This is the default mode.
BitmapFormat::RGB32	ffRRGGBB format. The alpha component is set to a constant value of 255 = 0xff, hence the bitmap is always opaque. This mode can be used to improve the performance of graphics output when painting on controls, especially on X11 platforms (Linux and FreeBSD).
BitmapFormat::ARGB32_Premultiplied	AARRGGBB format with red, green and blue components premultiplied by the alpha channel and divided by 255. This format is faster for bitmap renditions drawn with the Graphics and VectorGraphics classes.
