Scilab Function

driver - select a graphics driver

### Sequence d'appel

  `driver(driver_name)`
  `current_driver=driver()`

### Parametres

- `driver_name` : string, driver to be selected.

### Description

This function is used to select a graphics driver, or with no arguments to get the current graphics driver name. Most of the time, a user can ignore this function and change the driver by calling high level functions such as `xbasc` or `xbasimp`. The selected driver can be one of the followings:

- "X11" : output to the screen of the computer.
- "Pos" : output into Postscript format.
- "Rec" : output to the screen of the computer with recording of all the graphics commands. This is the default driver.
- "Fig" : output into XFig format. Clipping of objects is not provided in XFig.
- "GIF" : output into Gif format based on gd (http://www.boutell.com/gd)
- "PPM" : output into PPM format based on gd (http://www.boutell.com/gd)

### REMARK

To convert "GIF" or "PPM" files to other image format or for building animation one can use the "convert" program for ImageMagic (http://www.imagemagick.org/)

For example if one has generated a sequence of Gif files named `img*.gif` it is possible to build an animated Gif file (named anim.gif) by

    convert -delay 10  img*.gif anim.gif
