Abstract
A method and apparatus are provided for displaying image and facsimile data on a host-based application display. A host computer generates control and download command data for displaying the image or facsimile data. The image and facsimile data is processed by a non-programmable-terminal (NPT) or a programmable work station (PWS) for presentation of a display screen. When a user requests another function, the NPT or PWS stores image information and sends image information to the host computer. The save image information includes cache image counter data, scaling and viewed image screen location data that is used to restore the displayed image and facsimile data when the user returns to the previous function. Both the user and host application can specify a foreground color and a background color for the image and facsimile data display.
