Overview

Refer to Loading and Saving Large TIFF Files

Remarks

Specifies the offset within the current file of the page to load.

The LoadIFD property can be used to speed up the loading of TIFF files with many pages.

If the value of this property is <= 7, the LoadXXX methods will ignore this property. This property is only valid for TIFF files. The default value is 0, which indicates that the file format does not support IFDs.

If the value of this property is >= 8, then when information about a TIF file is retrieved, the page at the offset given by this property will be page 1. The page after will be page 2, etc. When the current TIF file is no longer needed, this property must be reset to 0, otherwise the processing of any other TIF files will be incorrect.
