-c ... channellist .... doubled quoted list of channels; 0, 1, 2 (or 3);
....................... any two or three may be specified;
....................... default "0 1 2 3" for CMYK; otherwise "0 1 2"
-d ... delay .......... time delay per frame (ms); delay >= 0; default=50
-r ... resize ......... image resize percentage; resize > 0;
....................... default=100 (unchanged)
-m ... colormodel ..... desired color space to convert (RGB/sRGB) image;
....................... default is infile colorspace: RGB/sRGB or CMYK
-i .................... includes the full color image in the animation
-l .................... disables the labeling of the images
-f .................... saves the animation to file animation.gif

PURPOSE: To display and optionally save an animation of the channels in an image.

DESCRIPTION: FLICKERCHANNEL automatically displays an animation from the channels of the supplied input image and optionally saves the animation to a file. At least two channels must be supplied. The main purpose of the script is to make a visual inspection of two (or more) channels of an image by alternating the display of each channel. The input image must be sRGB/RGB or CMYK. It may optionally be converted to any other valid colorspace by the script before the channels are labeled and displayed.

ARGUMENTS:

-c channellist ... CHANNELLIST is a double quoted list of the channels to be included in the animation. For CMYK, this defaults to "0 1 2 3", but can be any pair. For RGB or any other colorspace, this defaults to "0 1 2", but can be any pair.

-d delay ... DELAY is the time delay in msec between frames in the animation. Values are integers greater than or equal to zero. The default=10. Note that the animation will be created to loop forever.

-r resize ... RESIZE allows the animation to made larger or smaller than the input image size. The values are integers greater than 0 representing the resize percentage. The default=100 which leaves the animation the same size as the input image.

-m COLORMODEL is the desired color model in which to present the animation. Any valid IM colorspace is permitted, but if used, the infile must be in RGB/sRGB or CMYK colorspace. The default is the input colorspace.

-i ... Includes the full color infile in the animation.

-l ... Disables the labeling of the images.

-f ... Specifies that the animation is to be saved to a file called animation.gif
