This elements overlays SVG graphics over the video. SVG data can either be specified through properties, or fed through the data-sink pad.
Position and dimension of the SVG graphics can be achieved by specifying appropriate dimensions in the SVG file itself, but shortcuts are provided by the element to specify x/y position and width/height dimension, both in absolute form (pixels) and in relative form (percentage of video dimension).
For any measure (x/y/width/height), the absolute value (in pixels) takes precedence over the relative one if both are specified. Absolute values must be set to 0 to disable them.
If all parameters are 0, the image is displayed without rescaling at (0, 0) position.
The fit-to-frame property is a shortcut for displaying the SVG overlay at (0, 0) position filling the whole screen. It modifies the values of the x/y/width/height attributes, by setting height-/width-relative to 1.0. and all other attributes to 0.
