Emulate truecolor modes

Name

display-trueemu : Emulate truecolor modes

Synopsis

display-trueemu : [-parent=<mode>] [-dither=<dither>]
                  [-model=<model>] <target-spec>

Description

Emulates truecolor modes (GT_TRUECOLOR) on another target which can only do palette modes or truecolor modes of different sizes/depths. Uses dithering and special palettes to get the highest possible quality.

Options

'-parent=<mode>'

Force the parent target to use a specific mode, specified as a standard LibGGI mode string (see libggi(7)).

'-dither=<dither>'

Specifies the amount of dithering. Legal values are 0, 2 and 4, defaulting to 4. When the target is running, 'Ctrl-Alt-d' changes the dithering level.

'-model=<model>'

Color model to use (only when the parent is palettized). Legal values are rgb, cube and pastel. Default depends on the parent mode. When the target is running, 'Ctrl-Alt-p' changes the current color model.

target-spec

Specifies the target which to draw on (the parent target). This defaults to automatic selection (just like using 'ggiOpen(NULL)' when GGI_DISPLAY is not set).

Features

  • DirectBuffer never supported.
  • Unaccelerated.
