How do save the image?

 

[MikeLacey]

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