PURPOSE: To apply a map-like folded appearance to an image.

DESCRIPTION: PICTUREFOLD applies a map-like folded appearance to an image. A border or shadow optionally may be placed around the image.

ARGUMENTS:

-n numfolds ... NUMFOLDS is the number of folds. Values are integers>=2. The default=5.

-a angle ... ANGLE of fold. Values are 0<=integer<=40. The default=10.

-h height ... HEIGHT is the crop height as percent of the image height for desired region. Values are 5<=integers<=95. The default=95.

-l location ... LOCATION is the desired vertical crop location. Values are: north, south or center. The default=center.

-y yoffset ... YOFFSET is the percent vertical offset from the crop location. Values are -100<=integer<=100. The default=0.

-s shading ... SHADING brightness value. Values are 0<=integer<=100. A value of 0 is black and 100 is full image brightness. The default=70.

-t thickness ... THICKNESS is the border thickness. Values are integers>=0. However, for thickness=1, thickness will be set to 2 for functionality reasons. The default=0 (no border).

-b bdcolor ... BDCOLOR is the border color. Any valid IM color is allowed. The default=red.

-B bgcolor ... BGCOLOR is the background color. Any valid IM color is allowed. The default=white.

-o opacity ... OPACITY is the shadow opacity. Values are 0<=integer<=100. The default=0 (no shadow).

-d distance ... DISTANCE is the shadow distance (length). Values are integers>=0. The default=5.

-r ramp ... RAMP is the shadow ramping (tapering). Values are integer>=0. The default=5.

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.

What the script does is as follows:

  • Crops the image as desired
  • Creates a vertically striped mask with alternating sections of
    bright and dark and multiplies it with the image
  • Creates a white on black mask with alternately sheared sections
    and puts it in the alpha channel of the image
  • Optionally adds a border
  • Optionally adds a shadow
