预览器节点

预览器节点。

预览器 节点是一个临时性的，合成进程中的查看器。它可以放置在节点流程树中的任意地方以检查图像或者是值映射情况。

当场景中有多个预览器节点时，可以通过鼠标左键进行图像结果显示的切换。当在任意节点上使用 Shift-Ctrl-LMB 组合热键，将在此节点上自动连接一个查看器节点。

Note

It is possible to add multiple Viewer nodes, though only the active one(last selected, indicated with a slightly darker header) will be shown on the backdrop or in the Image editor.

Using the Image Editor

The viewer node allows results to be displayed in the Image Editor.The image is facilitated in the header by selecting Viewer Node in the linked Image data-block menu.The Image Editor will display the image from the currently selected viewer node.

To save the image being viewed,use Image ‣ Save As…, Shift-S to save the image in a file.

The Image Editor also has three additional options in its header to view Images with orwithout Alpha, or to view the Alpha or Z itself.Click and holding the mouse in the Image display allows you to sample the values.
