jit.alphablend

Use the alpha channel of one image to blend two images together

Description

The jit.alphablend object uses alpha channel (plane 0) of the input matrix in the left inlet as a per-cell crossfade value, and crossfades between the input matrices in the left and right inlets. In mode 0, a low value means more of the right input matrix, while a high value means more of the left input matrix. In mode 1, a low value means more of the left input matrix, while a high value means more of the right input matrix.
