Re: Re: Creating thumbnails

Still being new to perl I am not clear where the values of these variables in both of these subs are coming from?

sub thumb_with_gd
my ($infile, $outfile, $image, $error, $x, $y,
            $width, $height, $thumb);

sub thumbnail_dimensions
my ($x, $y, $ratio, $height, $width);

Thanks agian Cal

As far as I can see... They get their values later on in the sub, $infile and $outfile from the values passed to the sub, $image becomes the new image created from $infile, $x and $y it's dimensions, $width and $height the new dimensions, and $thumb the new image. Guess $error is a leftover from the ImageMagick version? As for thumbnail_dimensions... $x and $y are passed to the sub, $ratio is their quotient, and $width and $height are the new dimensions. The mys just give them an undef value. Hope this helps. Sorry if I misunderstood you.	[reply]
