NumberFlow, pixel nodes

These nodes are used to extract colors from a Texture2D or a Color array. Coordinates that are out of bounds are either clamped or repeated.

When sampling using UV coordinates from data with the same width and height as used in the diagram, you will get the exact pixel colors. This assumes you're not tweaking the UV coordinates yourself.

XY Clamped
Get a color using pixel coordinates. Coordinates are clamped.
XY Repeating
Get a color using pixel coordinates. Coordinates are repeated.
UV Clamped
Get a bilinear interpolated color using UV coordinates. Coordinates are clamped.
UV Repeating
Get a bilinear interpolated color using UV coordinates. Coordinates are repeated.
