Test viewer capility to recognize and effect picture behavior request on a basic CGM-to-HTML link, for behavior "_blank".
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 cyan circle object (APS) contains a hyperlink to a local HTML file instance. The hyperlink is a 'linkuri' APS attribute, and the picture behavior "_blank" is contained in the 3rd ("Behavior") parameter of the 'linkuri' attribute.
A mouse click anywhere over the cyan circle (labelled "second object") should cause the hyperlink to be executed. This should result in a new window being opened and the target HTML text to be displayed in the new window. Details of the size of the new window are unspecified in WebCGM 1.0.
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 new window, that is opened upon execution of the link. The size and shape of the window may vary, and are not part of the pass/fail criteria of this test.
