Raster Manager provides three (3) binary workmodes. Each workmode is designed to handle, manage and display binary (1-bit) image files in a specific way.

To ensure compliancy with versions before 2004 Edition, workmodes can be used to revert back to previous display modes.

A workmode is activated by using a configuration variable. There are 3 workmodes: Monochrome, Raster Reference, and 2-color. By default, when the configuration variable is not set, absent, or defined with an invalid value, the 2-color workmode is automatically set as the default workmode.

To set or change the default workmode:

1. Create the configuration variable MS_RASTER_1BIT_WORKMODE.
2. Assign a valid numeric value (0, 1 or 2) to the above configuration variable.
