TIEMultiBitmap.DuplicateCompressionInfo

TIEMultiBitmap.DuplicateCompressionInfo


Declaration

procedure DuplicateCompressionInfo(IncludePDFInfo: Boolean = False);


Description

Clone the compression information from idx 0 to all indexes.
If IncludePDFInfo=True, PDF page properties are also duplicated.

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