The origin (0, 0) of the coordinate system of most PDFs is positioned in the lower left corner. As defined in the PDF reference and in ISO-32000, positive X values are to the right and positive Y values are upwards. This is different from the specification of the coordinate system in other technologies. For instance: in Java AWT, positive Y values point downwards. In other words: it's normal, but it may seem awkward if you're used to another type of coordinate system. ------------------------------------------------------------------------------ This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev _______________________________________________ iText-questions mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/itext-questions Buy the iText book: http://www.itextpdf.com/book/ Check the site with examples before you ask questions: http://www.1t3xt.info/examples/ You can also search the keywords list: http://1t3xt.info/tutorials/keywords/
