Image::makeJPEG(3) Output a JPEG.


Void makeJPEG( Image img, Int qual=-1, String file="" )


img The image

qual The image quality (0..95). Alternatively, any negative number will use the default output quality.

file The file name to write to. This argument may be omitted to use standard output, which is useful in CGI scripts - call CGI.flush(3kaya) first to ensure the headers have been sent.


Outputs a JPEG from the image. This function should not be used with standard output in the webapp model - use Image.webJPEG(3kaya) instead.
