Run the test. No interaction required.

The test has passed if

• The top row has from left to right for a single graphic set:
  • A green square with a black circle inside of it
  • A black square
  • A black square with a green semicircle inside the lefthand side of the rect
  • A black square with a green semicircle inside the righthand side of the rect
• The middle row has from left to right for a single graphic set:
  • A green square with a white circle inside of it
  • A green semicircle pointing to the right on top of a white background
  • A green square with a white crest inside pointing to the right
  • A green square with a white crest inside pointing to the left
• The bottom row has from left to right for a single graphic set:
  • A green square with a black circle inside of it
  • A black square with a green semicircle inside pointing to the right
  • A green square with a circle inside that has a shadow on the righthand side and a reflection on the lefthand side
  • A green square with a circle inside that has a shadow on the lefthand side and a reflection on the righthand side

If the test shows any red, the test has failed.

This test verifies that the 'elevation' attribute is interpreted as a complementary value to the z-axis in degrees.

The test shows four different elevation angles that can be used for feDistantLight source. The four different feDistantLight light sources are used in three different filter cases; feDiffuseLight, feSpecularLight and feMerge which merges both feDiffuseLight and feSpecularLight to form a single filter. Using four different elevation values in three different filter cases gives twelve different filters. All twelve filter cases are applied to a vector graphic and then to a raster graphic. The vector graphic results are shown to the left and the raster graphic results are shown to the right.
