使用 PHP 合并两个图像

发布于 2024-09-26 05:57:13 字数 403 浏览 6 评论 0 原文

我正在尝试用 PHP 将两个图像合并在一起。

例如...我将如何使用基本 PHP 将图像一放在图像二之上或合并? 我尝试过诸如水印之类的方法,但似乎不起作用。

图片一

alt text

图片二

alt text

...它变成这样了吗? 最终结果:

alt text

I'm trying to merge two images together with PHP.

For example... how would I go about placing image one on top of image two or merge, with basic PHP?
I have tried something such as watermarking, but it doesn't seem to be working.

Image One

alt text

Image Two

alt text

...and have it turn into this? FINAL RESULT:

我从我做的一个开始就可以工作了。

<?php
$dest = imagecreatefrompng('vinyl.png');
$src = imagecreatefromjpeg('cover2.jpg');

imagealphablending($dest, false);
imagesavealpha($dest, true);

imagecopymerge($dest, $src, 10, 9, 0, 0, 181, 180, 100); //have to play with these numbers for it to work for you, etc.

header('Content-Type: image/png');
imagepng($dest);

imagedestroy($dest);
imagedestroy($src);
?>

I got it working from one I made.

<?php
$dest = imagecreatefrompng('vinyl.png');
$src = imagecreatefromjpeg('cover2.jpg');

imagealphablending($dest, false);
imagesavealpha($dest, true);

imagecopymerge($dest, $src, 10, 9, 0, 0, 181, 180, 100); //have to play with these numbers for it to work for you, etc.

header('Content-Type: image/png');
imagepng($dest);

imagedestroy($dest);
imagedestroy($src);
?>

问题是关于合并两个图像,但是在这种特定情况下您不应该这样做。您应该将内容图像(即封面)放入标签中,并将样式图像放入CSS中,为什么?

  1. 正如我所说,封面属于文档的内容,而黑胶唱片和阴影只是页面样式的一部分。
  2. 这样的分离使用起来就方便多了。用户可以轻松复制该图像。通过网络蜘蛛建立索引更容易。
  3. 最后,它更容易维护。

所以使用一个非常简单的代码:

<div class="cover">
   <img src="/content/images/covers/movin-mountains.png" alt="Moving mountains by Pneuma" width="100" height="100" />
</div>

.cover {
    padding: 10px;
    padding-right: 100px;

    background: url(/style/images/cover-background.png) no-repeat;
}

Question is about merging two images, however in this specified case you shouldn't do that. You should put Content Image (ie. cover) into <img /> tag, and Style Image into CSS, why?

  1. As I said the cover belongs to the content of the document, while that vinyl record and shadow are just a part of the page styles.
  2. Such separation is much more convenient to use. User can easily copy that image. It's easier to index by web-spiders.
  3. Finally, it's much easier to maintain.

So use a very simple code:

<div class="cover">
   <img src="/content/images/covers/movin-mountains.png" alt="Moving mountains by Pneuma" width="100" height="100" />
</div>

.cover {
    padding: 10px;
    padding-right: 100px;

    background: url(/style/images/cover-background.png) no-repeat;
}

ImageArtist 是我编写的纯 gd 包装器,这使您能够非常轻松地进行复杂的图像操作,为您的使用这个强大的库,只需很少的步骤即可完成问题的解决。

这是一个示例代码。

$img1 = new Image("./cover.jpg");
$img2 = new Image("./box.png");
$img2->merge($img1,9,9);
$img2->save("./merged.png",IMAGETYPE_PNG);

这就是我的结果。

输入图像描述这里

ImageArtist is a pure gd wrapper authored by me, this enables you to do complex image manipulations insanely easy, for your question solution can be done using very few steps using this powerful library.

here is a sample code.

$img1 = new Image("./cover.jpg");
$img2 = new Image("./box.png");
$img2->merge($img1,9,9);
$img2->save("./merged.png",IMAGETYPE_PNG);

This is how my result looks like.

您可以尝试我的功能,在不改变图像比例的情况下水平或垂直合并图像。只需复制粘贴即可。

function merge($filename_x, $filename_y, $filename_result, $mergeType = 0) {

    //$mergeType 0 for horizandal merge 1 for vertical merge

 // Get dimensions for specified images
 list($width_x, $height_x) = getimagesize($filename_x);

You can try my function for merging images horizontally or vertically without changing image ratio. just copy paste will work.

使用 GD 库或 ImageMagick。我在 google 上搜索了“PHP GD merge images”并找到了几篇关于这样做的文章。过去我所做的是创建一个大的空白图像,然后使用 imagecopymerge() 将这些图像粘贴到我原来的空白图像中。查看谷歌上的文章,您会发现一些可以立即开始使用的源代码。

Use the GD library or ImageMagick. I googled 'PHP GD merge images' and got several articles on doing this. In the past what I've done is create a large blank image, and then used imagecopymerge() to paste those images into my original blank one. Check out the articles on google you'll find some source code you can start using right away.

您可以使用 ImageMagick 扩展来执行此操作。我猜测组合图像()方法会做你想要的。

You can do this with the ImageMagick extension. I'm guessing that the combineImages() method will do what you want.

PHP 中的 GD 图像操作库可能是最适合在 PHP 中处理图像的库。尝试其中一种图像复制功能(imagecopy、imagecopymerge...)。它们每个都以不同的方式组合 2 个图像。有关详细信息,请参阅有关 imagecopy 的 php 文档

The GD Image Manipulation Library in PHP is probably the best for working with images in PHP. Try one of the imagecopy functions (imagecopy, imagecopymerge, ...). Each of them combine 2 images in different ways. See the php documentation on imagecopy for more information.
