screenSharedMemory

Type

property

Summary

Specifies whether images are drawn in shared memory on Unix systems.

Syntax

set the screenSharedMemory to {true | false}

Description

Use the screenSharedMemory property to improve drawing speed.

If the screenSharedMemory property is set to true, the engine uses the system's shared memory extension (if available) to draw images. This speeds up image rendering.

Shared memory is not available on all Unix systems, and cannot be used if the application is running across the network rather than locally.

If the application is started from a Unix command line, this property can be set to false on startup by using the -s option.

The setting of this property has no effect on Mac OS or Windows systems.

Examples
