Mode

The mode of an image defines the type and depth of a pixel in the image. The
current release supports the following standard modes:

   -

   *1* (1-bit pixels, black and white, stored with one pixel per byte)
   -

   *L* (8-bit pixels, black and white)
   -

   *P* (8-bit pixels, mapped to any other mode using a colour palette)
   -

   *RGB* (3x8-bit pixels, true colour)
   -

   *RGBA* (4x8-bit pixels, true colour with transparency mask)
   -

   *CMYK* (4x8-bit pixels, colour separation)
   -

   *YCbCr* (3x8-bit pixels, colour video format)
   -

   *I* (32-bit signed integer pixels)
   -

   *F* (32-bit floating point pixels)
