图像坐标节点

The Image Coordinates node outputs various coordinate fields for an input image. These outputs provide information about each pixel's location in different coordinate spaces, which can be useful for procedural texturing, compositing effects, or image-based masking.

The coordinate outputs are calculated per pixel based on the image resolution and placement within the compositor's virtual space.

输入

图像

用于确定坐标输出尺寸和位置的输入图像。

输出

均匀

以零为中心的规格化坐标，根据图像最大尺寸进行缩放。这对于需要与宽高比无关坐标的程序化效果非常有用，类似于着色器节点中的 物体 坐标。

规格化

Normalized coordinates ranging from 0 to 1 across the image dimensions, with half-pixel offsets to align with pixel centers.

像素

Pixel-space coordinates representing the center position of each pixel. These are integer-based coordinates with a half-pixel offset applied.
