The transformed image will display hightlights # from the outfit image and be distorted to match the wrinkles in the outfit image. # The outfitwarper script must be run once first using -E to create the lighting, # displacement and mask images. This can be done with or without -D directory. # # # OPTIONS: # # -r reduce ... REDUCE is the reduction amount as percent for the infile (pattern image) # before tiling it. Values are integers>=0. The default=10. # # -m modulate ... MODULATE is the modulation (lightness, saturation, hue) applied to the # infile (pattern image) before tiling it. Values are a comma separate triplet L,S,H of # integers>=0. The default="100,100,100" (no change). # # -x xroll ... XROLL is the roll amount in pixels for the tiled image in the horizontal # dimension. Values are integers. The default=0. # # -x yroll ... YROLL is the roll amount in pixels for the tiled image in the vertical # dimension. Values are integers. The default=0. # # -o orientation ... ORIENTATION angle in degrees for rotation of the tiled pattern # image. Values are -360<=integer<=360; default=0. # # -d displace ... DISPLACE is the displacement amount when applying the displacement # image to distort the pattern on the background image. Values are integers>=0. The # default=5. # # -D directory ... DIRECTORY to write all the exported data, including a text file # called outfit.txt containing the same textual parameter data as sent to terminal. # The directory can be specified later in the outfitwarp script to import all the # needed images and textual data. # # REQUIREMENTS: IM 6.5.3.4 due to the use of -compose displace. # # CAVEAT: No guarantee that this script will work on all platforms, # nor that trapping of inconsistent parameters is complete and # foolproof.
