问题 The code below crops the image well, which is what i want, but for larger images, it wotn work as well. Is there any way of 'zooming out of the image' Idealy i would be able to have each image roughly the same size before cropping so that i would get good results each time Code is <?php $image = $_GET['src']; // the image to crop $dest_image = 'images/cropped_whatever.jpg'; // make sure the directory is writeable $img = imagecreatetruecolor('200','150'); $org_img = imagecreatefromjpeg($image)

问题 I have many square images with different sizes, and I want to first resize them so they are inside a 150pixel area (so the images are not distorted, so since most images are not exactly the same size on both height and width one of the sides would be smaller (proportionally). Then once I do that I need to cut a perfect circle out of them and apply a 10pixel colored border. Now how on earth could I even start this? 回答1: Well, you take your files from disk or however and then you use them to

问题 Photoshop has that great: BiCube Shaper option for resizing. However I cannot find an equivalent. I've seen various code using GD that used imagecopyresampled and custom unsharp mask, but no where near the quality I am expecting.
