2.3.5.6 Multiframe Picture Display (%J)

The Multiframe Picture Display command allows the user to show a series of loaded pictures in succession. The pictures can come from any of the Cogsys picture loading/creating commands: Load Picture List, Load Referenced Pictures, or Create Pictures by CXR.

Multiframe Picture Display takes a sequence of triplets to specify the start picture, end picture and frames per picture that each image is to be displayed for.

Multiframe displays are synchronized to the monitor's raster beam, which ensures that an image is displayed for exactly the number of frames that the user specifies.

If a testlist uses any of the multiframe picture commands (Multiframe Picture Display %J, Response Multiframe Cycling Picture Display %K, or Response Multiframe Picture Display %L), Cogsys empirically measures the frame rate and appends lines to the output explicitly stating the refresh rate and frame speed for this experiment.

Name:

Multiframe Picture Display

Class:

Picture

Code:

%J

Syntax:

%J[start,end,frames [, start2, end2, frames2] ... ]
start and end are integers from 1 to one less than MAX_UNIQUE_PICS (by default,
frames is an integer from 1 to MAX_FRAMES ( No more than (MAX_PICSETS) triplets can be specified

System:

Displays the pictures from start to end for frame pictures each.

Requires:

Cogsys must be in a graphics mode, and the referenced pictures must be loaded.
