变换节点

此节点合并了其他三个节点的功能：缩放、移动和旋转节点。

输入

图像

标准颜色输入。

X、Y

用来在水平或垂直方向上移动输入图像。

角度

沿着图像中心对图像进行旋转。顺时针方向为正值，逆时针方向为负值。

缩放

从新定义图像尺寸。缩放比例是相对方式，也就是说数值0.5将尺寸缩放为原图像的一半大小，而数值2.0则将源图像缩放为原来的2倍大小。

采样

过滤

Determines how pixel values are interpolated when scaling or transforming images.

最近:

Uses the value of the closest pixel with no smoothing. This is the fastest method and is well-suited for pixel art or low-resolution images where sharp, blocky edges are desirable. In animations, motion appears in single-pixel steps, which can cause visible jittering.

双线性:

Averages the values of surrounding pixels to create a smoother result than Nearest. Provides a good balance between performance and visual quality.

双立方:

Computes a weighted average of a larger neighborhood of pixels for even smoother results. Ideal for photographic images or gradients where preserving fine detail is important.

各向异性:

Adjusts interpolation based on the direction and scale of the transformation. Helps reduce blurring or aliasing when scaling at steep angles or uneven resolutions, especially useful in textures viewed at oblique angles or in detailed 3D projections.

扩展 X/Y

将扩展模式应用于 X 轴。

剪辑:

图像之外的区域用透明填充。

扩选:

图像之外的区域由图像中最接近边界的像素填充。

重复:

图像之外的区域由图像重复填充。

输出
