Test viewer capility to recognize and effect picture behavior request on a basic CGM-to-HTML link, for target-frame behavior.
At the start of the test, the right-hand frame should display a WebCGM instance containing a simple picture with three objects: a magenta rectangle, a cyan circle, and a red triangle, all with thick black borders. The magenta rectangle object (APS) contains a hyperlink to a local HTML file instance. The hyperlink is a 'linkuri' APS attribute, and the frame name "referenceFrame" is contained in the 3rd ("Behavior") parameter of the 'linkuri' attribute.
A mouse click anywhere over the magenta rectangle (labelled "first object") should cause the hyperlink to be executed. This should result in the target HTML text being displayed in the left-hand frame.
The initial view in the left-hand frame is a PNG reference image of the text content of the HTML file that should appear in the left-hand frame, upon execution of the link. I.e., the execution of the link will overwrite the reference image with the HTML target text. The initial reference image has "-- PNG Reference --" written over it in red, to distinguish it from the HTML text which should appear after link execution. The style and layout of the HTML text may vary from the reference image, and are not part of the pass/fail criteria of this test.
