• File operator/screen-rgb-grey8.crimp — part of check-in [b0d870cef2] at 2011-12-15 01:25:30 on branch infinite-plane — Reorganized the binary ops, added result type to the generated file names, and added a few combinations always generating float, for operators like atan2 and hypot.

  Updated all users of the binop_*.c files. Reworked pow to use the binop machinery.

  Created special binary ops template for fpcomplex operations which are not element-wise (multiply, div), and updated the actual operators to use this. (user: andreask size: 583) [more...]

/*
 * Pixel- and channel-wise 1-(1-A)*(1-B) combination of two images. The images
 * have to have equal dimensions. This could be done at Tcl level using a
 * combination of 'multiply' and 'invert'. Doing it in C on the other hand
 * avoids the three temporary images of that implementation.
