All you want is a function that resizes an image to constraints (doesn't care if it should scale up or down), with possibility to select if you want to keep it proportional, and possibility to use either width or height as the constraint. Also, you want it to preserve transparency damn it! Surprisingly, I was unable to find a good function that does all that, so I decided to attempt writing it. This should do it. == Features/Usage: README.rdoc @@ -1,8 +1,13 @@ <? - function smart_resize_image( $file, $width = 0, $height = 0, $proportional = false, $output = 'file', $delete_original = true, $use_linux_commands = false ) { - if ( $height <= 0 && $width <= 0 ) { - return false; - } + function smart_resize_image($file, + $width = 0, + $height = 0, + $proportional = false, + $output = 'file', + $delete_original = true, + $use_linux_commands = false ) { + + if ( $height <= 0 && $width <= 0 ) return false; # Setting defaults and meta $info = getimagesize($file); @@ -13,9 +18,9 @@ # Calculating proportionality if ($proportional) { - if ($width == 0) $factor = $height/$height_old; - elseif ($height == 0) $factor = $width/$width_old; - else $factor = min( $width / $width_old, $height / $height_old ); + if ($width == 0) $factor = $height/$height_old; + elseif ($height == 0) $factor = $width/$width_old; + else $factor = min( $width / $width_old, $height / $height_old ); $final_width = round( $width_old * $factor ); $final_height = round( $height_old * $factor ); @@ -56,10 +61,8 @@ # Taking care of original, if needed if ( $delete_original ) { - if ( $use_linux_commands ) - exec('rm '.$file); - else - @unlink($file); + if ( $use_linux_commands ) exec('rm '.$file); + else @unlink($file); } # Preparing a method of providing result smart_resize_image.function.php 0837abf9fd14dcbb64aa4a0dc4d80fbbd29de87c Maxim Chernyak max@bitsonnet.com http://github.com/maxim/smart_resize_image/commit/8f2c53651bae87178d7e13dc85e23bb22a990bae 8f2c53651bae87178d7e13dc85e23bb22a990bae 2009-01-29T00:29:48-08:00 2009-01-29T00:29:48-08:00 Add formatting enhancements. 5848c425bf22a9aad1af6716712a9f11e26ef46e Maxim Chernyak max@bitsonnet.com
