For plug-in writers reference, these are equivalent: - (plug-in-waves RUN-NONINTERACTIVE - image - source-layer - amplitude - phase - wavelength - 0 - FALSE) + + (let* ( + (phi phase) + (width (car (gimp-drawable-get-width source-layer))) + (height (car (gimp-drawable-get-height source-layer))) + (aspect (/ width height)) + ) + + (while (< phi 0) + (set! phi (+ phi 360.0)) + ) + (set! phi (/ (- (modulo phase 360.0) 180.0) 180.0)) + + (if (< aspect 0.1) + (set! aspect 0.1)) + (if (> aspect 10.0) + (set! aspect 10.0)) + (gimp-drawable-merge-new-filter source-layer "gegl:waves" 0 LAYER-MODE-REPLACE 1.0 "amplitude" amplitude "phi" phi + "period" (* wavelength 2.0) + "clamp" TRUE "aspect" aspect) + ) Notes: * The old type argument is the negated value of "clamp". * The last argument (reflective) was unused.
