            Description

            The forums user updated a sample file with inverted text. After a little debugging it turns out that we where not correctly handling a cm token when in a text block. This is a very rare issue, most PDF writers will use a Tm token to do the text transforms and or the affinetransform in question is the identity matrix.

            However in this case the matrix define (ie. -1 0 0 -1 641.76 1036.35 cm) define the vertical and horizontal flip needed to draw the PDF text correctly.
