We have a compound PDF layout that uses relative positioning of components.

Recently, we added a component that displays an image read from a BLOB. Unfortunately, the component seems to ignore the image dimensions, displaying the image behind the next component and beyond the page area limits.

Is this supposed to work? We are on a fairly buggy 8.1.03 server (upgrade to 8.2 is due).
Alternatively, is there some method to obtain the BLOB's image dimensions so that we can be specific about the required component dimensions?

Our compound document looks like this:

SET PRINTPLUS = ON
SET HTMLARCHIVE		= ON
SET FILECOMPRESS	= OFF

...is there some method to obtain the BLOB's image...

Can you place those images in an associated App Folder and address them in that location?

I don't know of a way doing so from within WF. The BLOBs are in an Oracle 11.2 DB.

However, we do have these images available through a separate (custom) servlet, which places them under a URL - does that help us in any way? It would give us a MIME-type, that's a start...

I suppose we could extend our servlet to also allow fetching meta-data about the images... How are we going to query that source though, since we don't have the webservices adapter?
I suppose the least problematic approach would be to add this information to the Oracle database somehow (a stored function seems a good idea), but I'll have to shift the burden onto some colleagues in that case.

So, I gather that WF is supposed to behave like it does with respect to the image size vs. the component dimensions? I suppose in either case I should open a PR.
