Select the Xconfig file in which you want to configure drawing settings and open the Exceed onDemand Xconfig dialog box. On the Performance page, select the appropriate drawing settings from the Drawing area. These settings let you manage drawing and backing store configuration to optimize performance.
Exact Zero-Width Lines Enables thin lines to be drawn and forces exact line drawing for zero-width lines. The X protocol states that zero-width (thin) lines are one-pixel-wide lines drawn using an unspecified, device-dependent algorithm. A line width of zero may differ from a line width of one in which pixels are drawn. This permits the use of many manufacturers' line-drawing hardware, which may run faster than the more precisely specified wide lines.
By default, Exceed onDemand lets the native operating system directly draw zero-width lines. This method is generally much faster than the exact-pixel algorithm used by X to draw lines of other widths.
Note: |
Certain video drivers ignore color information on some styles of zero-width line drawing. If lines appear in an incorrect color or do not appear at all, select this option. |
Draft Mode Improves performance with a slight and generally unnoticeable reduction in drawing accuracy.
Batch Requests Can help improve the performance of Exceed Connection Server.
Limit Window Exposures Saves an image of each top-level window to avoid sending expose events when windows are moved. This results in reduced bandwidth and improved performance. This option is enabled by default.
Backing Store See Configuring Backing Store Settings.
Save Unders You can use this setting to reduce network traffic and improve window refresh speed at the expense of window drawing speed and memory. When this option is enabled, Exceed onDemand avoids repeats (when small windows such as menus are closed) by saving background windows locally.
