    Public Methods
     NameDescription
    Public MethodGetCacheKeyFor internal use. Returns a key uniquely identifying the object in its GrapeCity.Documents.Pdf.GcPdfDocument, can return null if object can not be uniquely identified.  
    Public MethodGetImageStreamInfoReturns the GrapeCity.Documents.Pdf.Spec.PdfStreamObject containing unparsed image data and information about the PDF filter and decode parameters.

    Note that not all derived classes support this method (for example, PdfImageHandler).

     
    Public MethodGetNativeImageCreates and returns a GrapeCity.Documents.Imaging.GcBitmap object representing the current PdfImageBase object.

    IMPORTANT NOTE: the returned bitmap must be disposed after use.

    An image in a PDF can be specified as an "image mask" (see ImageMask), in which case the image data is used as a stencil mask for painting in the current color specified by currentUnmaskedColor, maskedColor specifies the color of the area excluded from filling (it is transparent in most cases).

     
    Public MethodGetPdfStreamGets the System.IO.Stream object containing the data of GrapeCity.Documents.Pdf.Spec.PdfStreamObjectBase owned by this wrapper. Note! The stream should be disposed after usage. (Inherited from GrapeCity.Documents.Pdf.Wrappers.PdfWrapperBase)
    Public MethodGetPdfStreamDataGets the data of GrapeCity.Documents.Pdf.Spec.PdfStreamObjectBase owned by this wrapper. (Inherited from GrapeCity.Documents.Pdf.Wrappers.PdfWrapperBase)
    Public MethodGetPdfStreamInfoGets the GrapeCity.Documents.Pdf.Spec.PdfStreamInfo object containing the data of GrapeCity.Documents.Pdf.Spec.PdfStreamObjectBase owned by this wrapper. Note! The stream should be disposed after usage. (Inherited from GrapeCity.Documents.Pdf.Wrappers.PdfWrapperBase)
    Public MethodToGcBitmapRetrieves the underlying GrapeCity.Documents.Imaging.GcBitmap object, or creates a new GrapeCity.Documents.Imaging.GcBitmap that contains the image data.

    Note that you should dispose the returned GrapeCity.Documents.Imaging.GcBitmap if disposeAfterUse is true.
