The TIFF-F sub-format requires a number of tags, some of which I can not seem to set with ImageEn:
1) NewSubFileType - This is included in the output, but is set to 0 (it needs to be set to 2: bit1=1). There does not appear to be a way to explicitly set it.
2) PageNumber - Setting TIFF_PageNumber, TIFF_PageCount, and/or TIFF_ImageIndex does not insert this tag into the output (the PageNumber tag should be two shorts: [0] = page number (base 0); [1] = total pages in file.
3) DateTime - No way to set.
PS - Just out of curiousity, what does TIFF_ImageIndex do? I can't find any reference to an ImageIndex tag in the TIFF standard and no such tag appears in the output file.

Hi Eric
That is correct. It is not data of frame, but the index of the image with which to load.

To follow up on TIFF_ImageIndex, is this param even relevant when writing/appending a TIFF image to a file? I had assumed that it set a tag in the file, but from your description, it seems like it's actually for reading/display purposes. |

Hi,
starting from version 4.1.2 NewSubFiltType is settable with other values other than 0.
DateTime is settable with IOParams.EXIF_DateTime (TIFF tag 306) |

Hi
I'm afraid we do not fully support the TIFF-F format.
TIFF_ImageIndex is simply the current image that is displayed of a multiframe TIFF, i.e. set to 0 to display the first frame, 1 to display the second frame, etc.
