This filter takes the current accumulated + background image (i.e., the entire reference graphic) as input, shifts its offscreen + down, blurs it, and then writes the result to the canvas. Note that the offscreen for + the filter is initialized to transparent black, which allows the already rendered + rectangle, circle and triangle to show through after the filter renders its own + result to the canvas. + </p> + <p> + The second subtest enables background image processing and instead invokes the + ShiftBGAndBlur filter on the inner ‘g’ element. The accumulated background at the + time the filter is applied contains only the rectangle. Because the children + of the inner ‘g’ (i.e., the circle and triangle) are not part of the inner ‘g’ element's + background and because ShiftBGAndBlur ignores SourceGraphic, the children of the inner ‘g’ + do not appear in the result. + </p> + <p> + The third subtest enables background image processing and invokes the ShiftBGAndBlur on the + ‘polygon’ element that draws the triangle. The accumulated background at the time the filter + is applied contains the rectangle plus the circle ignoring the effect of the ‘opacity’ + property on the inner ‘g’ element. (Note that the blurred circle at the bottom does not + let the rectangle show through on its left side. This is due to ignoring the effect of + the ‘opacity’ property.) Because the triangle itself is not part of the accumulated background + and because ShiftBGAndBlur ignores SourceGraphic, the triangle does not appear in the result. + </p> + <p> + The fourth subtest is the same as the third except that filter ShiftBGAndBlur_WithSourceGraphic is + invoked instead of ShiftBGAndBlur. ShiftBGAndBlur_WithSourceGraphic performs the same effect as + ShiftBGAndBlur, but then renders the SourceGraphic on top of the shifted, blurred background + image. In this case, SourceGraphic is the blue triangle; thus, the result is the same as in + the fourth case except that the triangle now appears. + </p> + </d:testDescription> + <d:operatorScript xmlns="http://www.w3.org/1999/xhtml"> + <p> + Run the test.
