Download and resize PHP

Question

I am working on a script that loads an image using PHP, and I want it to resize the image by 180 before saving it.
I tried using the WideImage library and → saveFileTO (...), but when I enable WideImage.php on the page, the page bypasses!
So here is my script, if you can help me and tell me how to do this, save the modified version

You can use the PHP GD library to resize the image at startup.

The following code should give you an idea of ​​how to implement resizing:

// Get the image info from the photo $image_info = getimagesize($photo); $width = $new_width = $image_info[0]; $height = $new_height = $image_info[1]; $type = $image_info[2]; // Load the image switch ($type) { case IMAGETYPE_JPEG: $image = imagecreatefromjpeg($photo); break; case IMAGETYPE_GIF: $image = imagecreatefromgif($photo); break; case IMAGETYPE_PNG: $image = imagecreatefrompng($photo); break; default: die('Error loading '.$photo.' - File type '.$type.' not supported'); } // Create a new, resized image $new_width = 180; $new_height = $height / ($width / $new_width); $new_image = imagecreatetruecolor($new_width, $new_height); imagecopyresampled($new_image, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height); // Save the new image over the top of the original photo switch ($type) { case IMAGETYPE_JPEG: imagejpeg($new_image, $photo, 100); break; case IMAGETYPE_GIF: imagegif($new_image, $photo); break; case IMAGETYPE_PNG: imagepng($new_image, $photo); break; default: die('Error saving image: '.$photo); }

You can use the class that I wrote for this task:

http://code.google.com/p/image2/source/browse/#svn/trunk/includes/classes

 <?php try { $image = new Image2($path_to_image); } catch (NotAnImageException $e) { printf("FILE PROVIDED IS NOT AN IMAGE, FILE PATH: %s", $path_to_image); } $image -> resize(array("width" => 180)) -> saveToFile($new_path); // be sure to exclude the extension $new_file_location = $image -> getFileLocation(); // this will include the extension for future use

You do not even need to use the WideImage library.

Check out this script here: http://bgallz.org/502/php-upload-resize-image/

You start by loading the image and saving it into a temporary image file. This script runs a form with inputs for maximum height or maximum width. Then it will create a new image file based on the new width / height, and then copy the temporary image to the new one created on the server.

You see this with the following code:

 // Create temporary image file. $tmp = imagecreatetruecolor($newwidth,$newheight); // Copy the image to one with the new width and height. imagecopyresampled($tmp,$image,0,0,0,0,$newwidth,$newheight,$width,$height);
