Topic: Matrix question

hi - have a question on the matrices used in PDFs - hope someone can help.
I understand the q, Q and cm to a degree, and my implementation currently keeps the matrix stack and all that other stuff. Iím only working on images atm; but Iím moving over to text soon.
Is the text matrix dependant on the CTM, as built up from the q, Q and cm in the stream, or is the text matrix independent. E.g.: if I want to find the location of a stringlet of text, do I have to first transform with CTM, and then by the text matrix, or just transform with the text-matrix?
Any and all help appreciated :)
