SYNTAX

#include <xite/Xslice.h>

void xslice( Widget wid, IMAGE image,
Colormap map, int planes );

IMAGE colorbar_image( long xsize, long ysize,
long low, long high, Visual *visual,
char *title );

Widget colorbar_widget( Widget parent,
    char *resource_name,
    char *shell_resource_name, int colortab,
    long xsize, long ysize, long low, long high,
    Visual *visual, int depth, char *title,
    image_callbacks *callbacks );

DESCRIPTION

xslicemakes a piecewise constant lookup table (LUT) ofpseudocolors. Colors may be mixed in a palette by specifyingrgb or ihs values.

colorbar_imagereturns a BIFF image where each rowcontains pixel values from lowto high,linearlyincreasing. The image size is determined by xsize(horizontal) and ysize(vertical). The image is one-bandif the class of visualis PseudoColor, otherwise it isthree-band. If lowequals high,the default values 0and 255 are used for lowand highrespectively.

colorbar_widgetreturns a colorbar widget. colortabis an index into the list of available colortables for theimages (shown by the "Colors" menu in an image). With anegative value for colortab,a default value equal to thelast colortable in the "Colors" menu will be used.
