the bitmap image. This buffer should normally be pitch*scaled_height
bytes in size, where scaled_height is determined by calling
tjScaledSize() with the height of the desired output image. This pointer
may also be used to decompress into a specific region of a

(NOTE: scaled_width can be determined by calling tjScaledSize().) You can
also be clever and use this parameter to skip lines, etc. Setting this
parameter to 0 is the equivalent of setting it to scaled_width*pixelsize.
