C# / .Net: Tiff file page properties?

[BCT]

Hi there,
i am new to GDPicture library, having trail license for developing in C# .Net.
Wanting to merge (multi/single-page) tiff files together, for getting a multi-page tiff file as output.
Knowing each tiff file has its own file properties --> thinking each tiff file page can have its own page properties/tags.

Like merging a scan of a document (text; 1 page) and a scan of a drawing (image; 1 page), to one file, having page 1 as text and page 2 as image.

Is it possible to detect/ get out of page 2 that it has jpeg compression by example?

I have a loop over all pages in the output document, then method TagCount i have a loop over the tags, reading them with TagGetName(imageid, tagno) and TagGetValueString(imageid, tagno), but getting everytime the same tags (name and value) over all the pages.
I am getting the compression on page 1 which is the same as on page 2, i dont see differences in the compression, as i would expect it to see.

Do the methods support page tags/properties, or only at document level (there is no page number to be supplied, and i use the SelectPage(imageid) insided my page loop)?

Looking forward for a reply.
