note 30690 added to function.imagecopyresized

I wrote a JPEG resize function that will allow you to spefify locations, quality, as well as determine aspect ration. I guess it could be good for thumbnailing... //resizes a jpg and place in a desired destination //keeps aspect ratio normal //directory must have read/write priv //requires GD1 or 2 /* RETURN KEY 1 = source file not found 2 = successfully completed 3 = errors occured */ function image_resize_jpeg( $img_source, $img_dest, $img_quality, $size_limit ) { if ( !file_exists( $img_source ) ) return (1); //file not found return 1 //load the original image and put its hieght/width in $img_info $img_info = getimagesize ( $img_source ); //$img_info ARRAY KEY //1 = hieght //2 = width //3 = hight and width string $orig_height = $img_info[1]; //source hieght from $img_info $orig_width = $img_info[0]; //source width from $img_info $jpegQuality = $img_quality; //quality of the JPG if(($orig_width > $size_limit) || ($orig_height > $size_limit)) //make sure the image isnt already resized { if ( $orig_height > $orig_width ) $scaledown = $orig_height; else $scaledown = $orig_width; $newscale = $size_limit / $scaledown; //set the new scale size //calculate the new aspect ratio $new_w = abs($orig_width * $newscale); $new_h = abs($orig_height * $newscale); //create the blank limited-palette image $base_image = imageCreate($new_w, $new_h); //convert and save it to temp.jpg imagejpeg($base_image, './temp.jpg'); //get the image pointer to the temp jpeg $image = imageCreateFromJpeg('./temp.jpg'); $dir = dir("./$img_source"); //directory path of the orig image // get the image pointer to the original image $imageToResize = imageCreateFromJpeg("./$img_source"); //resize the original image over temp.jpg // NOTE: of you have GD2, you could also use imageCopyResampled imageCopyResized($image, $imageToResize, 0, 0, 0, 0, $new_w, $new_h, $orig_width, $orig_height); //create the resized image imageJpeg($image, "./$img_dest", $jpegQuality); //image destination unlink('./temp.jpg'); //del the temp image file return (2); //completed successfully } else { return(3); //errors occured } } -- http://www.php.net/manual/en/function.imagecopyresized.php http://master.php.net/manage/user-notes.php?action=edit+30690 http://master.php.net/manage/user-notes.php?action=delete+30690 http://master.php.net/manage/user-notes.php?action=reject+30690
