Public Property TIFFIFDOffset As Long |
The number of bytes preceding the IFD.
This property applies when using the FileName property, or the LoadBlob, LoadBuffer, or LoadBufferPtr methods. When reading the file or memory buffer, the control begins at the offset specified by the FileOffset property. This property is useful when reading non-standard files with embedded image data, files with multiple images, or where a header of known size is pre-pended to an image file.
This property is zero based, such that the beginning of the file is considered 0, not 1.
