PURPOSE: To apply an embroidery effect to each color in an image.

DESCRIPTION: EMBROIDERY applies an embroidery effect to each color in an image. The image must have limited number of colors or only the top most frequent colors will be used. Each color will get the same pattern, but at different rotation angles.

ARGUMENTS:

-n numcolors ... NUMCOLORS is the number of desired or actual colors in the image. Values are integers>0. The default=8.

-p pattern ... PATTERN is the weave pattern. The choices are either linear (1) or crosshatch (2). The default=1.

-t thickness ... THICKNESS is the weave thickness. Values are integers>=1. The default=2.

-g graylimit ... GRAYLIMIT limits (converts) the colors near black and near white to gray(graylimit%) and gray(100%-graylimit%). Values are 0<=integers<=100. The default=20.

-f fuzzval ... FUZZVAL is the fuzz value used for recoloring near black and near white. Values are 0<=integers<=100. The default=5.

-b bgcolor ... BGCOLOR is the actual background color in the image. The default is most the frequent color.

-P process ... PROCESS is the embroidering processing for the background color. The choices are: yes (y), no (n) or transparent (t). If no, the bacgkround color will not be emroidered. If transparent, the background color in the output image will be repaced with transparency. If no or transparent options are used, you may need to disable the shadow via -extent and/or -intensity. The default=yes

-a angle ... ANGLE is the initial pattern angle used for the background color. Values are -360<=integers<=360. The default=0 (horizontal)

-r range ... RANGE is the range of pattern angles over all the colors. Values are 0<=integers<=360. The default=90 (deg).

-i intensity ... INTENSITY is the shadow intensity. Higher is darker. 0 is no shadow. Values are 0<=integers<=100. The default=25.

-e extent ... EXTENT is the shadow extent in pixels. Values are integers>=0. 0 is no shadow. The default=2.

-B bevel ... BEVEL is the pattern bevel amount. Values are integers>=0. The default=4.

-A azimuth ... AZIMUTH is the bevel azimuth angle. Values are -360<=integers<=360. The default=130.

-E elevation ... ELEVATION is the bevel elevation angle. Values are 0<=integers<=90. The default=30.

-C contrast ... CONTRAST is the bevel sigmoidal-contrast amount. Values are integers>=0. The default=0 for IM >= 6.7.9.5; otherwise default=1 (no added contrast).

-S spread ... SPREAD is the pattern spread (diffusion). Values are integers>=0. The default=1.

-N newseed ... NEWSEED is the pattern (new) seed value. Values are integers>=0. The default is a random seed value.

-M mix ... MIX is the mixing of the before and after spread result. Values are 0<=integers<=100. 100 is all spread. 0 is no spread. The default=100

-G gain ... GAIN in pattern contrast. Values are 0<=integers<=100. The default=0.

NOTE: The input image should be completely opaque. If not and if a background color is explicitly specified, then any transparency will be flattened against the background color to remove it. Otherwise, the alpha channel will be disabled.

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:

  • Gets the top numcolors that are most frequently used in the image
  • Creates a colormap image and applies -remap to ensure only those
    colors are in the image
  • Limits black and white to gray(20%) and gray(80%)
  • Creates one of two tiled out pattern images
  • Isolates each color in the image as a new image, rotates the pattern
    by different amounts and applies a softlight composite
  • Flattens all the processed color images into the output image
