note 33630 deleted from function.imagecopyresized by aidan

Note Submitter: viral at noeticsolutions dot com ---- First of all, I would like to thank people above for the sample code to do thumbnail(ing). I am using Linux 4.2.2 and GD 1.6.2. I was have a wierd problem with the resizing. In most cases a black line (of 1 pixel) used to be added either towards the right, bottom or at both places. To solve this I modified one of the sample code above to chop off 1 pixel from both the width and the height so that I do not get the black line. The revised code is as under: function image_resize_jpeg( $img_source, $img_dest, $img_quality, $size_limit ) { if ( !file_exists( $img_source ) ) { return (1); //file not found return 1 } // increase the $size_limit variable by 1 as it is going to be chopped by 1 below $size_limit++; //load the original image and put its hieght/width in $img_info $img_info = getimagesize ( $img_source ); //$img_info ARRAY KEY //0 = width //1 = hieght //2 = image type //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 $new_w = (int)abs($orig_width * $newscale); $new_h = (int)abs($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'); imagedestroy($base_image); //get the image pointer to the temp jpeg $image = imageCreateFromJpeg('./temp.jpg'); // 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); $new_image = imageCreate($new_w - 1, $new_h - 1); imagecopy ($new_image, $image, 0, 0, 0, 0, $new_w - 1, $new_h - 1); //create the resized image imageJpeg($new_image, "./$img_dest", $jpegQuality); //image destination imagedestroy($image); imagedestroy($new_image); imagedestroy($imageToResize); unlink('./temp.jpg'); //del the temp image file return (2); //completed successfully } else { return(3); //errors occured } }
