DCLTONE(1)

NAME
dcltone - display the DCL tone pattern (fill pattern) chart

SYNOPSIS
dcltone [ group_number ] [ options ]

DESCRIPTION
dcltone is a utility program included in the GFD Dennou Club Library (DCL). It displays a chart of available tone patterns (fill patterns used for shading areas). DCL tone patterns are identified by a 3-digit integer index. This program displays a specific "group" of patterns based on the hundreds digit.

  Operation
The program opens a 600x600 pixel window (default) and draws a 6x6 grid.

•   The argument group_number (0 to 6) specifies the hundreds digit of the pattern index.

•   The vertical axis represents the tens digit (00-50).

•   The horizontal axis represents the ones digit (0-5).

For example, if you run dcltone 6, the grid will display patterns from index 600 (bottom-left) to 655 (top-right). If the command-line argument group_number is not specified, the program will interactively prompt for the number.

OPTIONS

group_number
    An integer between 0 and 6 specifying the pattern group to display.
    NOTE: If you wish to use any runtime options (like setting the window size), you MUST provide this group_number as the first argument. If omitted while options are present, the program will try to parse the option string as a number and crash.
    0 : Dot patterns (coarse to fine)
    1-5 : Various hatching patterns (lines, checks, etc.)
    6 : Cross-hatching and complex patterns

dcltone also accepts standard DCL runtime parameters:

-sw_iwidth=pixels
    Specify the window width.

-sw_iheight=pixels
    Specify the window height.

EXAMPLES
To display tone patterns in the 600s series:

    $ dcltone 6

To display group 0 with a custom window size (note that '0' is required):

    $ dcltone 0 -sw_iwidth=400 -sw_iheight=400

To run interactively (no arguments allowed):

    $ dcltone
     TONE PATTERN (0-6) (I) ? ;
     1
