Options- For an Outer Shadow, if using the Shadow Source effect, there is an option for Infill which will fill inside of the shadow (the area that would be behind the original source).Outer shadows give the sense of the source floating over the top of the canvas, while inner shadows make the source appear as if it is in a cutout below the canvas.
For an inner stroke, both the filter and source have the option Ignore Source Border which will suppress drawing a stroke anywhere the masked content meets the edge of the source (e.g.- if your masked facecam is aligned with the bottom of the source). Options- For an Outer Stroke if using the Stroke Source there is an option for Infill Zero Offset which will fill inside of the stroke if the offset is zero.Outer strokes are drawn from the edge of the mask outward, while inner strokes are drawn from the edge of the mask inward over the top of the original source. Position- Select either Outer Stroke or Inner Stroke.Source- Only available when used as a source Select the source used to generate the stroke.
