# display-trueemu(7)

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
