How do save the image?

RE: need basic operational GD module help

From the Perl documentation

png

$image->png object method
This returns the image data in PNG format. You can then print it, pipe it to a display program, or write it to a file. Example:

        $png_data = $myImage->png;
        open (DISPLAY,"| display -") || die;
        binmode DISPLAY;
        print DISPLAY $png_data;
        close DISPLAY;
Note the use of binmode(). This is crucial for portability to DOSish platforms.


So to write the image data to a file you could say:

        $png_data = $myImage->png;
        open(F,">file.png")
            || die "Can't create file.png\n$!\n";
        print F $png_data;
        close F;
