Hello,
Do you mean the FillOrder TIFF tag?
If yes, this tag is controlled automatically by the toolkit when you save TIFF images. If you want to reverses the bit order when writing CCITT Group 3 and 4 files (and also RAW uncompressed data), so that the least significant bit (LSB) is first, you need to set the ESO_REVERSEBITS value in the Flags member of the SAVEFILEOPTION structure before using our L_Save... functions.
However, if you must change a tag manually, you can always use the L_SetTag and L_WriteFileTag functions to do that.
About the IFD offset, this is also handled automatically by the toolkit, and we don't have a function to set it manually.
Thanks,
Maen Badwan
