The put_MaskName method specifies the name of a JPEG file to use as the wipe mask. This mask will be used instead of one of the built-in wipe masks. The file must contain a monochrome, 8-bits-per-pixel gradient. The gradient is used as a mask to define the wipe's progression.
HRESULT put_MaskName( BSTR newVal );
[in] Specifies the name of the file.
Returns S_OK or an error code.
To revert to a built-in mask, set the MaskNum property.
