What makes pdf_text_align fail in pdfinclude?

[Bruce Noble]

I have been using pdfinclude for years, and never came across this one. I have a call to pdf_text_align that works perfectly when the data comes from source "a", but generates no text in the PDF file when the data source is "b". I have thoroughly debugged the code to ensure that there are no problems with the PDF file being open, font name and point size are correct, X and Y coordinates are correct. What have people experienced with this routine that results in no text being generated?

I am still having this problem. Since nobody has responded, that's usually a strong indicator that nobody else has experienced this - likely meaning my logic issue, etc. Does anyone have any way of debugging what goes on with a pdf_text_align call so that I might see why it is generating blank space instead of printable text? Are there any debugging procedures/calls/etc. that give you a window into what is going on?

I message the data to the screen immediately after the call to pdf_text_align, and it is always correct, not blank.
