TextureToArray_v2 Op

TextureToArray

There is a newer version of this op!


This version will not receive any updates. It is recommended to use a newer version.

Current version: Ops.Gl.TextureToArray_v3

extract colors from a texture


This op will take an incoming texture and convert each color pixel value to an Array 4 (RGBA).

When using 32bit textures your array values will be in the range of 0.0-1.0. 8bit textures will have values of 0-255.

Be careful with using high resolution textures. For example a texture of only 100x100 pixel will result in 40,000 values: Red 10,000 Green 10,000 Blue 10,000 Alpha 10,000
