bitmapOfForeignPtr :: Int -> Int -> BitmapFormat -> ForeignPtr Word8 -> Bool -> Picture #

O(1). Use a ForeignPtr of RGBA data as a bitmap with the given width and height.

The boolean flag controls whether Gloss should cache the data between frames for speed. If you are programatically generating the image for each frame then use False. If you have loaded it from a file then use True.

bitmapOfByteString :: Int -> Int -> BitmapFormat -> ByteString -> Bool -> Picture #

O(size). Copy a ByteString of RGBA data into a bitmap with the given width and height.

The boolean flag controls whether Gloss should cache the data between frames for speed. If you are programatically generating the image for each frame then use False. If you have loaded it from a file then use True.

bitmapOfBMP :: BMP -> Picture #

O(size). Copy a BMP file into a bitmap.

bitmapDataOfBMP :: BMP -> BitmapData #

O(size). Copy a BMP file into a bitmap.

loadBMP :: FilePath -> IO Picture #

Load an uncompressed 24 or 32bit RGBA BMP file as a bitmap.
