SharePoint 2013 图像再现质量

Question

有没有办法设置图像再现功能的质量？
默认情况下，它创建的图像设置较低，会产生大量压缩伪影。

Answer 1

我不完全确定您所说的图像再现质量是什么意思。如果您指的是压缩质量，我无能为力，但您可以使用 SharePoint 设计管理器更改分辨率。

1. Verify that the user account that is performing this procedure has, at minimum, Design permissions to the top-level site of the site collection.
2. In a browser, go to the top-level site of the publishing site collection.
3. Choose the Settings icon. On the Site Settings page, in the Look and Feel section, choose Image Renditions.
4. On the Image Renditions page, choose Add new item.
5. On the New Image Rendition page, in the Name box, enter a name for the rendition. For example, enter Thumbnail_Small.
6. In the Width and Height text boxes, enter the width and height, in pixels, of the rendition, and then choose Save.

我做了一些研究，似乎没有办法改变图像编码质量!
看看这个 MSDN 线程: https://social.technet.microsoft.com/Forums/windows/en-US/da7ff7ca-0064-4ada-a6a5-d007b3714233/encoding-parameters-for-imagerenditions?forum=sharepointgeneral
我认为唯一的“解决方案”可能是提供更大的分辨率并使用 CSS 缩小它。
