Choices are # either 18 variants in the collage or 8 variants in the collage. Variants are # randomized in position, orientation and scale. An optional overlay image may # be added with 4 choices of number and positions of the variants added atop # of the collaged input image. # # OPTIONS: # # -d dimensions ... DIMENSIONS are the WidthxHeight of output. If only one # value is specified, then the output will be a square. If neither are # provided, then the output will be the size of input. Values are integers>0. # The default is the size of input. # # -b bgcolor ... BGCOLOR is the background color for the output image. Any # valid opaque IM color is allowed. The default is black. # # -m mode ... MODE is either all (a) or half (h); all uses 18 variants of the # input image in the collage. Half uses only 9 variants of the input image # in the collage. The default is all. # # -n newseed ... NEWSEED is the seed value for the randomization of the # variants. Values are integers>0. The default causes every output to be # different. Use of any other value will cause the output to be repeatable. # # -p pattern ... PATTERN for the optional overlay image. The choices are: # 1, 2, 3 or 4. 1 is one copy in the middle or over the whole output based # upon the scale value. 2 is a variant in the southeast and northwest corners. # 3 is a variant in the southwest and northeast corners. 4 is a variant in # all 4 corners of the output. The default=1. # # -s scale ... SCALE is the scale factor for the overlay image variants # expressed a as a percent of the output image dimensions. Values are # 00. The default=10. # # NOTE: The optional overlay image should be a mostly transparent image so # that it does not cover too much of the collage. # # CAVEAT: No guarantee that this script will work on all platforms, # nor that trapping of inconsistent parameters is complete and # foolproof. Use At Your Own Risk. # ###### # # set default values dimensions="" # WxH of output; if only one, then will be square; if none, then will be size of input bgcolor="black" # background color newseed="" # random seed mode="all" # all (18) or half (9) image pattern pattern=1 # overlay pattern: 1, 2, 3 or 4 radius=50 # vignette radiusius as percent of half image dimensions: 00 scale=50 # overlay scale for copies as percent of overlay dimensions 0&2 "" echo >&2 "$PROGNAME:" "$@" sed >&2 -e '1,/^####/d;
