Example: pdf.addDataMatrix(srcDoc, page, "Sometext", 87 * POINTS_PER_MM, PAGE_H - 60 * POINTS_PER_MM - DM_H_ABS, 1f); This for example would mean that the text had to be positioned 87millimeters from the left hand side and 60 millimeters from the top of the page minus the expected height of the data matrix. It allows the user of the API to directly use typical CI/CD guideline measurements in metric format, while the drawImage() method of the PDPageContentStream object inside PDFBox always expects points in floats as input. Your mileage might vary on this level of abstraction. I found them to be very useful and certainly wished that those be accessible via public interface instead inside PDFBox. Cheers Roberto
