DCLCLR(1)

NAME
dclclr - display the DCL colormap (palette)

SYNOPSIS
dclclr [ options ]

DESCRIPTION
dclclr is a utility program included in the GFD Dennou Club Library (DCL). It displays a chart of the currently selected colormap (palette) used for graphics rendering. DCL manages colors using an indexed color system. This program draws a grid showing the available colors and their corresponding index numbers.

  Default Behavior
By default, DCL uses an internal default colormap. You can change the colormap by specifying the sw_iclrmap parameter.

OPTIONS
dclclr accepts standard DCL runtime parameters in the format -group_param=value. The most relevant options are:

-sw_iclrmap=number
    Specify the colormap index number.
    Example values:
    1 : Default colormap (HLS)
    11, 13, 15... : Various color scales

-sw_clrmap=filename
    Specify an external colormap file path directly.

-sw_iwidth=pixels
    Specify the window width (default: 600).

-sw_iheight=pixels
    Specify the window height (default: 600).

EXAMPLES
To display the default colormap:

    $ dclclr

To set the window size to 400x400:

    $ dclclr -sw_iwidth=400 -sw_iheight=400
