Editing Enterprise (computer) (section)

=== Graphics ===

Enterprise has four hardware graphics modes: 40-column text modes, Lo-Res and Hi-Res [[raster graphics|bit mapped]] graphics, and attribute graphics. The OS offers 80-column text via high-resolution graphics mode. Bit mapped graphics modes allow selection between displays of 2, 4, 16 or 256 colours (from a [[List of monochrome and RGB color formats#3-3-2 bit RGB or 8-8-4 levels RGB|3-3-2 bit RGB palette]]), but horizontal resolution decreases as colour depth increases. [[Interlacing (bitmaps)|Interlaced]] and non-interlaced modes are available. The maximum resolution is {{Resx|640|512}} [[pixels]] interlaced, or {{Resx|640|256}} pixels non-interlaced. These resolutions permit only a 2-colour display. A 256-colour display has a maximum resolution of {{Resx|80|256}}. The attribute graphics mode provides a {{Resx|320|256}} pixel resolution with 16 colours, selectable from a palette of 256.

Multiple pages can be displayed simultaneously on the screen, even if their graphics modes are different. Each page has its own palette, which allows more colours to be displayed onscreen simultaneously. The page height can be larger than the screen or the window it is displayed on. Each page is connected to a channel of the EXOS operating system, so it is possible to write on a hidden page.
