TIEMultiBitmap.DuplicateCompressionInfo

Declaration

procedure DuplicateCompressionInfo(IncludePDFInfo: Boolean = False);

Description

Clone the compression information from the image at index 0 to all other images.
If IncludePDFInfo=True, PDF page properties are also duplicated.

Note:
◼Only relevant if ParamsEnabled = True
◼Has no effect in IsVirtual mode
