Hello, I use PdfContentStreamProcessor and a listener to extract text from certain rectangles on pdf pages, for instance a customer number always appearing at the same position on the pages of a file.
I assumed I could use a single PdfContentStreamProcessor object and call ProcessContent() with it for every page of the file. It looked as if this would work until I had to work with a pdf file that contains a modification of the CTM in the graphics state on every page. This was shift to right of about 16 points. I found out that this shift was cumulative, i.e. the text positions where shifted for 16 points on the first, 32 points on the second page and so on. I could get rid of the problem by using a new PdfContentStreamProcessor object for every page. My question: is this behaviour: cumulative effects of changes to the graphics state between calls to ProcessContent() intended or is it a bug?
