in reply to Resize image width & height...

I wrote this for an online image gallery. I wanted the 'long' dimension to be no larger than 450 pixels, so my script needed to do the resizing before commiting the file to disk and I needed to write down the height and width attributes so that I could modify the HTML to display the image correctly. Here's my code:

# write the file to a temporary location my $tmp_loc = $TEMP_IMG_DIR . $image_name; my $whan; open($whan,">$tmp_loc") || die "Cannot write $tmp_loc $!"; print $whan $temp_file_var; close($whan); # Resize image and write it to the appropriate location use Image::Thumbnail; my $t = new Image::Thumbnail( size => 450, create => 1, inputpath => $tmp_loc, outputpath => $main_loc ); # Get the new size of the main image use Image::Info qw(image_info dim); my $info = image_info($main_loc); my ($w, $h) = dim($info);
$temp_file_var is holding the image.
At the end, the new image is written to the path in $main_loc and I have the width $w and the height $h of the new image.

I hope that you can modify this for your use!
