使用包含其他图像的GD创建图片 [英] Create a picture with GD containing other images

问题描述

我想在PHP中创建一张由不同其他图片组成的GD图片。例如，我有6张图片（或更多），我想创建一张包含这些不同图片的图片。

I would like to create a picture in PHP with GD composed by different other pictures. For example I have 6 pictures (or more) and I would like to create ONE picture who contain these different pictures.

难度是我的最终图片必须有一个固定的宽度和高度（304x179），因此如果不同的图片太大，则必须剪切。这是IconFinder的一个例子：

The Difficulty is that my final picture must have a fixed width and height (304x179), so if the different pictures are too big they must be cut. This is an example from IconFinder :

这张图片有6张图片http://cdn.iconfinder.net/design/images/_thumbs/is_twitter.png

这张图片由6张图片组成，但切割第3只鸟（绿色），在底部切割4,5和6。这就是我想要的，你能帮我用PHP编写这段代码吗？

This picture is composed by 6 images, but the 3rd bird (green) is cutted, and the 4, 5 and 6 are cutted in the bottom. This is what I want, can you give me some help to write this code in PHP ?

谢谢

推荐答案

创建主图像并将其视为画布。

Create your primary image and consider it your "canvas."

从那里，使用 imagecopy（）将较小的图像复制到画布图像中。

From there, use imagecopy() to copy the smaller images into the canvas image.

请参阅此示例：

<?php
header('Content-Type: image/jpg');
$canvas = imagecreatetruecolor(304, 179);
$icon1 = imagecreatefromjpeg('icon.jpg');
$icon2 = imagecreatefromjpeg('icon2.jpg');
// ... add more source images as needed
imagecopy($canvas, $icon1, 275, 102, 0, 0, 100, 100);
imagecopy($canvas, $icon2, 0, 120, 0, 0, 100, 100);
// ... copy additional source images to the canvas as needed
imagejpeg($canvas);
?>

在我的例子中， icon.jpg 是我放置在画布上的100x100图像，其左上角位于画布中的275,102处，切断了右侧。

In my example, icon.jpg is a 100x100 image which I am placing in the canvas such that its top left corner is located at 275, 102 in the canvas, which cuts off the right side.

我将代码调整为与您正在进行的操作更相似。

I adjusted the code to be more similar to what you're doing.
