COP Input VEX node

Returns a pixel value in one of the 4 input COPs connected to the VEX COP.

See also: Is Connected

This operator returns a pixel value in one of the 4 input COPs connected to the VEX COP. The pixel may be in any plane, at any position, at any time. Use 'No Filtering' if you aren’t querying a pixel at a different location than the current pixel, since it is the quickest input method. Use 'Bilinear Filtering' for doing subpixel queries. Use 'Full Filtering' when warping or transforming the input pixels, or when maximum filtering is required (it is the slowest but best quality filtering method).

The plane_index, array_index, u, v, and frame inputs all default to the value of global variables if they are not connected. The default values are as follows:

       plane_index     = PI
               array_index     = AI
               u               = IX or X as appropriate for the
signature
               v               = IY or Y as appropriate for the
signature
               frame           = F
