尝试使用PHP在签名图像上呈现头像图像

Question

I am making a dynamic signature generator and I would like to add a avatar image in part of the signature. How would I do this as well as sizing down the image?

Answer 1

Here is an example.

I have 2 images:

1. https://s-media-cache-ak0.pinimg.com/736x/d1/2e/9e/d12e9ecd9f4c4e45dafa5880c7d99c73.jpg
2. http://cf.juggle-images.com/matte/white/280x280/php-1-logo-primary.jpg

Steps:

1. Set the content type header - in this case image/jpg
2. Create new canvas, width: 720, height: 637
3. Create two new images from file or URL, $icon1 & $icon2
4. Copy part of $icon1 to $canvas
5. Copy and resize part of $icon2 to $can
6. Output image to browser

<?php
header('Content-Type: image/jpg');
$canvas = imagecreatetruecolor(720,  637);
$icon1 = imagecreatefromjpeg('https://s-media-cache-ak0.pinimg.com/736x/d1/2e/9e/d12e9ecd9f4c4e45dafa5880c7d99c73.jpg');
$icon2 = imagecreatefromjpeg('http://cf.juggle-images.com/matte/white/280x280/php-1-logo-primary.jpg');

//add 2 source images
imagecopy($canvas, $icon1, 0, 0, 0, 0, 720,  637);
imagecopyresized($canvas, $icon2, 0, 0, 0, 0, 100, 100, 280, 280);

//Output image to browser
imagejpeg($canvas);
?>
