Window
compositing node
Cuts a small window out of a larger image.
See also: Crop
This operation reduces the resolution of the image, and allows you to focus in on a specific area of the image. It does not replace the area outside the windowed area with black; the original image information is kept.
This operation effectively does a Transform and Crop.
If Large Canvas support is off, this node does exactly the same thing as the Crop operation.
Parameters
|
Method |
The window area can either be represented by 2 opposite points of a rectangle, or the rectangles lower left corner and its width and height. |
|
Units |
Specifies the units to crop in, either pixels or UV. |
|
Horizontal Area |
The left/right bounds of the window area. This parameter cannot be animated; use the Offset parameter to pan the image through the window. |
|
Vertical Area |
The bottom/top bounds of the window area. This parameter cannot be animated; use the Offset parameter to pan the image through the window. |
|
Offset |
An animatable image offset, so the image may be panned through the area. |
