• File operator/montageh-grey16.crimp — part of check-in [122bdc7d78] at 2011-12-14 21:53:28 on branch infinite-plane — Continued from previous commit. Left to check/modify are

  unary: ahe, convolve, region_sum, rof

  binary: atan2, hypot, pow, cannyinternal, complex div/multiply, join, joint-bilateral, threshold

  other: warp-field, cut (*)

  (*) Currently done via 'crop', semantic mismatch. Better as their own operator. (user: andreask size: 1201) [more...]
