Member Function Documentation

static Texture2D Hydrogen.Texture.AutoCrop ( this Texture2D  texture,
Color  borderColor 
)
static

Autocrop the texture removes the borders from the texture. It searches the active layer for the largest possible border area that's color matches borderColor, and then crops this area from the image, as if you had used the Crop tool.

Returns
The cropped image.
Parameters
textureThe source texture.
borderColorThe border color used in the crop calculations.
