缩小以适合 FOP 中的图像 [英] Scale down to fit an image in FOP

问题描述

我使用 FOP 1.0 版来创建 PDF.在其中一个页面中，我想显示一个图像(2552 x 4200 像素)，如果它不完全适合页面，则将其缩小.据我在 邮件列表 上看到推荐的方法如下:

I am using FOP version 1.0 to create PDFs. In one of the pages I'd like to display an image (2552 x 4200 pixel) and scale it down if it doesn't fully fit on the page. As far as I could see on the mailing list the recommended way of doing this would be following:

<fo:external-graphic inline-progression-dimension.maximum="100%" 
                     content-height="scale-down-to-fit" 
                     content-width="scale-down-to-fit" 
                     src="..."/>

不幸的是，这仍然不能显示整个图像.图像的下部被切掉.谁能告诉我我可能做错了什么?

Unfortunately, that still doesn't display the whole image. The lower part of the image is cut off. Can anyone give me a hint on what I am potentially doing wrong?

推荐答案

我在这里找到了这个页面解释如何使用 XSL-FO 进行缩放.

本质上，这是我用来使它工作的代码片段:

Essentially, this is the snippet that I used to make it work:

<fo:external-graphic
    src="url('...')"
    width="100%"
    content-height="100%"
    content-width="scale-to-fit"
    scaling="uniform"
    xsl:use-attribute-sets="img"/>

我发现 width="100%" 是您自己尝试中缺失的部分.希望这对未来的访问者有所帮助.

I found that width="100%" was the missing piece in your own attempts. Hope this helps future visitors.
