ImageSoftMaskResourceID Property

Apitron PDF Kit help
Apitron.PDF.Kit library for .NET
Gets or sets the soft mask resource ID of the image XObject defining a soft-mask image that shall be used as a source of mask shape or mask opacity values in the transparent imaging model. The alpha source parameter in the graphics state determines whether the mask values shall beinterpreted as shape or opacity. If present, this entry shall override the current soft mask in the graphics state, as well as the image’s Mask entry, if any. However, the other transparency-related graphics state parameters—blend mode and alpha constant—shall remain in effect. If Soft Mask is absent, the image shall have no associated soft mask (although the current soft mask in the graphics state may still apply).
