The image looks like: [transparent][ red ] [ green ][ blue ] The third image in the first line is the XPM image rotated in 180 degrees. It should looks like: [ blue ][ green ] [ red ][transparent] but displayed as: [transparent][ green ] [ red ][ black ] The first image in the second line is the PNG image without rotation. The transparent pixel is displayed as black. The second to fourth image in the second line are the PNG images rotated in 90 to 270 degrees. They are invisible as if the entire images are transparent.
