将空白添加到图像并将文件保存到服务器 [英] Add whitespace to image and save file to server

问题描述

我有一个脚本可以为简报生成一些HTML。我使用align = left浮动图像并在其周围包装文本。我使用内联CSS样式，在这种情况下是margin-right，为图像提供一些喘息空间。 Outlook忽略了这一点。 Outlook也忽略了填充 - 我甚至尝试了10px的边框右边，它也忽略了它。

I have a script that generates some HTML for newsletters. I'm floating an image using "align=left" and wrapping text around it. I use an inline CSS style, in this case margin-right, to give the image some breathing room. Outlook ignores this. Outlook also ignores padding - I even tried a 10px border-right, it ignored that, too.

我无法更改布局并将图像放在表格中。我正在考虑使用GD来操作图像，在其右侧添加8px的空白。因为这是一个向成千上万的人发送的时事通讯，因此我需要将修改后的图像保存到某个地方的服务器，以便我可以链接到它。我不想在运行中生成这个。

I can't change the layout and put the image in a table. I am thinking of using GD to manipulate the image, adding 8px of whitespace to the right side of it. The catch is, since this is a newsletter going out to thousands of people, is that I then need to save the modified image to the server somewhere so I can link to it. I don't want to generate this on the fly.

我没有使用GD的经验或使用PHP将文件保存到某个位置。这是我的图像代码：

I have zero experience with GD or saving files to a location with PHP. Here is my image code:

<img alt="<?php print $main2['title']; ?>" height="127" width="185" src="http://www.mydomain.com/uploads/<?php print $main2['filename']; ?>" align="left" style="margin:8px 8px 0 0;"/>

推荐答案

你当然可以依靠CSS来发送简讯 - 只是肯定仅限属性和内联。我们运行了一系列非常成功的广告系列，每个人的新闻简报都很合适。

You can certainly rely on CSS for newsletters - just certain properties only, and inline. We run a very successful set of campaigns and the newsletters look just fine for everyone.

我们的网络服务器上有一个文件夹，这里不是一个问题。千小修改后的图像。

It's not a problem that we have a folder on our web server where there are a few thousand small modified images.

我们不能改变布局，因为这是一些重要的人想要的 - 重要的人付给我相当多的钱来做他们想要的事情发生。是的，我可以提出一个很大的臭味，并可能说服他们，但如果我可以反过来花几个小时让它工作，为什么不呢？

We can't change the layout, well, because that's what some important people want - and the important people pay me a decent amount of money to make what they want happen. Yeah, I could raise a big stink about it and probably convince them otherwise, but if I could conversely spend a few hours and get it to work, why not?

FWIW ，我确实设法用GD完成了 - 没有我想的那么复杂 - 如果其他人需要它会发布脚本：

FWIW, I did manage to get this done with GD - wasn't as complicated as I thought - will post the script if anyone else needs it:

// get image
$url = 'myimage.jpg';
$src = imagecreatefromjpeg($url);

// dimensions (just to be safe, should always be 185x127 though)
$src_wide = imagesx($src);
$src_high = imagesy($src);

// set white padding color
$clear = array('red'=>255,'green'=>255,'blue'=>255);

// new image dimensions with right padding
$dst_wide = $src_wide+8;
$dst_high = $src_high+8;

// New resource image at new size
$dst = imagecreatetruecolor($dst_wide, $dst_high);

// fill the image with the white padding color
$clear = imagecolorallocate( $dst, $clear["red"], $clear["green"], $clear["blue"]);
imagefill($dst, 0, 0, $clear);

// copy the original image on top of the new one
imagecopymerge($dst,$src,0,8,0,0,$src_wide,$src_high, 100);

// store the new image in tmp directory
$pth = 'tmp/myimage.jpg';
imagejpeg($dst, $pth, 100);

// free resources
imagedestroy($src);
imagedestroy($dst);
