/SMaskInData integer
(Optional for images that use the JPXDecode filter, meaningless otherwise; PDF 1.5) A code specifying how soft-mask information (see 11.6.5.3, "Soft-Mask Images") encoded with image samples shall be used: 0 If present, encoded soft-mask image information shall be ignored. 1 The image’s data stream includes encoded soft-mask values. A conforming reader may create a soft-mask image from the information to be used as a source of mask shape or mask opacity in the transparency imaging model. 2 The image’s data stream includes colour channels that have been preblended with a background; the image data also includes an opacity channel. A conforming reader may create a soft-mask image with a Matte entry from the opacity channel information to be used as a source of mask shape or mask opacity in the transparency model. If this entry has a nonzero value, SMask shall not be specified. See also 7.4.9, "JPXDecode Filter". Default value: 0.
Qualifier: Optional for images that use the JPXDecode filter, meaningless otherwise; PDF 1.5
