Save image to a file

File format is deduced from the filename extension (if any).

Use the extension "XXX" (eg. "image.XXX") to automatically select the extension according to param_image. PNM is used for grayscale or RGB, PAM for RGBA, Y4M ottherwise. "XXX" placeholder in filename is replaced with used extension. It is user responsibility to ensure that @ref filename is writable in this case.
