note 40238 added to function.imagecopyresized

One thing I'd really like to be able to accomplish is similar to that done by the short Perl script below, where I am able to specify ONLY the largest single side I wish to have (whether it's x or y is irrelevant), and have the thumbnail thus created. For example, scaling an image down to a minithumbnail with no side larger than say 95 pixels, I could do this: <img src="cgi-bin/thumb.cgi?size=<?php echo $size; ?>&amp;image=<?php echo "$image_fullpath$image_file"; ?>"> Script follows: ------------------- #!/usr/bin/perl -T # mini_thumb.cgi use warnings; use strict; #local user's installed Perl modules go here use lib '/www2/home/domain.com/perl'; # These three may need to be installed from CPAN use CGI qw/:standard -no_xhtml/; use GD; use Image::GD::Thumbnail; if ( param('image') && param('size') ) { # you can't call the script without em my $imagefile = param('image'); my $largest_size = param('size'); # Security untaint # must be absolute path, no wildcards, for a clean non-abusable untaint # must be /fullpath/to/image/(filename).jpg or boom! die "Bad Imagefile" unless $imagefile =~ m#^( # start capture /www2/home/domain\.com/html/ # full path _(?:images|thumbnails)/ # don't capture either-or dir choice [-\w\d._]+jpg # jpeg filename )$#x; # end capture, whitespace is irrelevant $imagefile = $1; # Security untaint die "Bad Size" unless $largest_size =~ m#^(\d{1,3})$#; $largest_size = $1;# must be 1-3 digits or boom! # sanity check die "Insane size value: $largest_size" unless (20 < $largest_size and $largest_size < 200); die "Bad Filename: '$imagefile' does not exist" unless -e $imagefile; die "File not readable: $imagefile has bad permissions" unless -r _; # three - argument open, again security related open IN, '<', "$imagefile" or die "Could not open $imagefile: $!"; my $src = GD::Image->newFromJpeg(*IN); close IN or die "Could not close: $!"; # x and y are the new dimensions, but we basically throw those away here. my ($thumb, $x, $y) = Image::GD::Thumbnail::create($src, $largest_size); #ensure stream is treated as binary data binmode STDOUT; #ensure we have a proper header for the browser to understand print header(-type=>'image/jpeg'); # and here's the resized image. print $thumb->jpeg; } __END__ If someone could replace this with a note on how this may be accomplished in PHP I'd be eternally grateful. ---- Manual Page -- http://www.php.net/manual/en/function.imagecopyresized.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+40238 Delete -- http://master.php.net/manage/user-notes.php?action=delete+40238&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+40238&report=yes Search -- http://master.php.net/manage/user-notes.php
