# USAGE: shapemorph2 -c1 cpts1 -c2 cpts2 [-f frames] [-d delay] [-p pause] [-r] [-b bcolor] infile1 infile2 outfile # shapemorph2 [-h or -help] # -c1 cpts1 control point x,y coordinates in infile1 # -c2 cpts2 control point x,y coordinates in infile1 # -f frames number of frames in animation; frames>1; default=20 # -d delay delay between frames; delay>0; default=10 # -p pause pause delay for two undistorted input images; # pause>0; default=100 # -r reverse the animation sequence and append it to the end # -b bcolor background color when morph distortion goes off the images; # default=black PURPOSE: To create a shape morphing animation sequence between two images. # DESCRIPTION: SHAPEMORPH2 creates a shape morphing animation sequence between # two images using multiple corresponding control point specified from each of # the two input images. The control points along with the four fixed corners # actually form the set of control points that are used to fill out X and Y # displacement maps (images) that are then used to transform the geometry of # each image to the other. The corresponding frames from the transformation # of each image are then blended proportional to the progression of frames. ARGUMENTS: # -c1 cpts1 ... CPTS1 is a list of the x,y pairs of control points for infile1. # This argument is mandatory and must have atleast one x,y pair. Points must be # listed in the same order as the corresponding points in infile2. # -c2 cpts2 ... CPTS2 is a list of the x,y pairs of control points for infile2. # This argument is mandatory and must have atleast one x,y pair. Points must be # listed in the same order as the corresponding points in infile1. -f frames ... FRAMES is the total number of frames in the animation (including infile1 and infile2 as the start and end frames. Values are integers > 1. The default is 20. -d delay ... DELAY between frames. Values are integers>0. The default=10 -p pause ... PAUSE is the delay to use for the first and last frame of the animation, i.e. the delay for each of the input images. The default=100 -r ... If supplied, then reverse the animation sequence, remove the first and last frames of the reversed sequence and append these reversed frames to the end of the animation. # -b bgcolor ... BGCOLOR is the background color to use when the morph # distortion goes off either image. The default=black. A value of none # can be used for transparency for the background. # REQUIREMENTS: IM 6.4.2-4 or higher due to the use of -distort shepards.
