TImageEnMIO.DuplicateCompressionInfo
TImageEnMIO.DuplicateCompressionInfo
Declaration
procedure DuplicateCompressionInfo(IncludePDFInfo: Boolean = False);
Description
Clone the compression information of page 0 to all frames of the current image.
If
IncludePDFInfo=True, PDF page properties are also duplicated.
The following properties are duplicated:
General◼BitsPerSample◼SamplesPerPixelTIFF◼TIFF_Compression◼TIFF_PhotometInterpret◼TIFF_PlanarConf◼TIFF_Orientation◼TIFF_EnableAdjustOrientation◼TIFF_JPEGQuality◼TIFF_JPEGColorSpace◼TIFF_FillOrder◼TIFF_ZIPCompression◼TIFF_StripCount◼TIFF_Normalize32fImagesGIF◼GIF_InterlacedICO◼ICO_FormatPS◼PS_CompressionPDF◼PDF_Compression◼PDF_PaperWidth (if
IncludePDFInfo=True)
◼PDF_PaperHeight (if
