## 2.1.2 Producing images on disk

The remaining terminals listed in Table 2.1 direct graphical output to disk in a selection of rasterised and vector graphics formats. The filename of the resulting image file may be set using the `set output` command, as in the example:

    set output 'my_plot.eps'

Use of rasterised image formats inevitably results in some loss of image quality since the plot has to be rasterised into a bitmapped graphic image. By default, this rasterisation is performed at a resolution of , though this may be changed using the `set terminal dpi` command, which should be followed by a numerical value. Alternatively, the resolution may be changed using the `DPI` option in the `settings` section of a configuration file (see Chapter 9).
