Yes, AX-1 reads and writes multiple-image TIFF files. TIFF specifications define the TAGs for Page-Number and Page-Total as being optional. As a result many multi-page TIFF files do not have these TAGs.
When reading a non-existing subfile AX-1 returns an error. To find the last image in a TIFF file an application must enter into a loop that includes a Read and increment ReadSubfile until a Multi-Page-Error is returned.
When AX-1 is called to append an additional image to a TIFF file, it writes the Page-Number and Page-Total TAGs into the file, unless the corresponding properties are set to zero.
The Axtel DEMO program keeps reading successive images from a TIFF file if the same file is opened over and over again. To write a multi-image TIFF file with the Axtel DEMO click on Options in the toolbar, select TIFF write, and mark the field for: Allow multi image TIFF.
