display-trueemu(7) 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
