Texture Ripper
The Texture Ripper node allows you to extract an arbitrary 4-point quad from a source image and remap it perfectly flat onto your output.

Parameter Reference
INPUTTYPEDEFAULTDESCRIPTION
Input ImageSampler2DNoneThe source image or texture atlas you want to extract from.
Point Top LeftVector20.0, 0.0The top-left corner of your extraction quad in normalized UV space.
Point Top RightVector21.0, 0.0The top-right corner of your extraction quad.
Point Bottom LeftVector20.0, 1.0The bottom-left corner of your extraction quad.
Point Bottom RightVector21.0, 1.0The bottom-right corner of your extraction quad.
Mapping MethodEnumPerspectiveControls the math used to warp the quad. Perspective uses a homography matrix for true 3D correction. Bilinear does a simple 2D interpolation.
Fit ModeEnumFitDetermines how the extracted quad scales to the output resolution: Stretch, Fit, Fill, Original Size.
Filter ModeEnumBilinearTexture sampling method. Set to Bicubic for smoother, sharper results when upscaling small extracted areas.
Background ColorColorBlack (Alpha 0)The color applied to areas outside the bounds of the extracted quad.
