Editing Geom string

A '''geom string''' is a special configuration setting in [[Eternity]] which allows specification of all of the characteristics of a video mode in a single string.

==Syntax==
The syntax of a geom string is as follows:

<code>
WWWWxHHHH[flags]
</code>

Where WWWW is the width, between 320 and the maximum supported system window width; HHHH is the height, between 200 and the maximum supported system window height; and [flags] is an optional valid combination of the following single-letter specifiers:
{| class="wikitable" style="font-size: 85%"; text-align: center; width: auto
!style="background-color: #C5D0E1"| Flag
!style="background-color: #E3EEFF"| Description
|-style="background-color: #F5F5F5"
| w
| Selects windowed mode.
|-style="background-color: #D9D9D9"
| f
| Selects fullscreen mode.
|-style="background-color: #F5F5F5"
| a
| Selects "asynchronous" or non-page-flipped updating.
|-style="background-color: #D9D9D9"
| v
| Selects page-flipped updating.
|-style="background-color: #F5F5F5"
| s
| Selects "software" surface.
|-style="background-color: #D9D9D9"
| h
| Selects "hardware" surface (eg. DirectDraw acceleration)
|-style="background-color: #F5F5F5"
| n
| Creates primary window without a window frame, where supported.
|-
!style="background-color: #C5D0E1"| Flag
!style="background-color: #E3EEFF"| Description
|}

==Examples==
The following are examples of valid geom strings.

<code> 
 320x200w
 640x480f
 1024x768wan
 1280x800fvh
