### 4.7 Graphics options

#### 4.7.1 capture

Command-line option: `--capture=<value>`
Environment variable: `LW6_CAPTURE`
XML key: `capture`

  Type: boolean

  Default value: false

  Enables capture mode, in which a BMP file is dumped on the disk (in your user directory, search for a ’capture’ sub-directory).

#### 4.7.2 fullscreen

Command-line option: `--fullscreen=<value>`
Environment variable: `LW6_FULLSCREEN`
XML key: `fullscreen`

  Type: boolean

  Default value: false

  Force the game to fun fullscreen. Note that the graphics backend might ignore this hint.

#### 4.7.3 gfx-backend

Command-line option: `--gfx-backend=<value>`
Environment variable: `LW6_GFX_BACKEND`
XML key: `gfx-backend`

  Type: string

  Default value: gl1

  Sets the graphics backend AKA ’gfx’ to use. For now the only reasonnable choice is ’gl1’ and will use an OpenGL v1 / SDL 3D-accelerated driver.

#### 4.7.4 gfx-quality

Command-line option: `--gfx-quality=<value>`
Environment variable: `LW6_GFX_QUALITY`
XML key: `gfx-quality`

  Type: integer

  Default value: 1 Min value: 0 Max value: 2

  Sets the overall quality of the graphics backend. Depending on the backend, this can mean different things. For instance for the ’gl’ backend, this can change texture filtering (nearest, linear, bilinear...). This is not the same as ’pixelize’ which is a per-map option and emulates an old school appearance.

#### 4.7.5 height

Command-line option: `--height=<value>`
Environment variable: `LW6_HEIGHT`
XML key: `height`

  Type: integer

  Default value: -1

  Run the game with the given screen height.Note that the graphics backend might ignore this hint. Use with its companion option ’width’. A negative value will force the use of a default value.

#### 4.7.6 width

Command-line option: `--width=<value>`
Environment variable: `LW6_WIDTH`
XML key: `width`

  Type: integer

  Default value: -1

  Run the game with the given screen width. Note that the graphics backend might ignore this hint. Use with its companion option ’height’.A negative value will force the use of a default value.

#### 4.7.7 windowed-mode-limit

Command-line option: `--windowed-mode-limit=<value>`
Environment variable: `LW6_WINDOWED_MODE_LIMIT`
XML key: `windowed-mode-limit`

  Type: float

  Default value: 0.95

  When switching back from fullscreen mode to windowed mode, if we’re in maximum resolution, then this coefficient will be applied before resizing the window. The idea is that (obviously) a windowed mode is prefered when a little smaller that totally fullscreen. So set this to a value just below 1.0.
