IMWRITE Write Matrix to Image File

Section: Input/Ouput Functions

Usage

Write the image data from the matrix into a given file. Note that FreeMat's support for imread is not complete. Only some of the formats specified in the MATLAB API are implemented. The syntax for its use is
  imwrite(filename, A)
  imwrite(filename, A, map)
  imwrite(filename, A, map, alpha)

where filename is the name of the file to write to. The input arrays A contain the image data, map contains the colormap information (for indexed images), and alpha contains the alphamap (transparency). The returned values will depend on the type of the original image. Generally you can write images in the jpg,png,xpm,ppm and some other formats.
