DrawText

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Simple task is to draw text, add an annotation, in one of the 4 corners of the page.  This annotation will be added to either just the first page or all pages.  Please note that I do not control how the PDFs are created.  I am using the code at the bottom.

The issue I am having is that some pages contain a single object and if that image is rotated 90 degrees clockwise, then an annotation added to the bottom-left corner will run up the bottom right corner when displayed in a PDF viewer, Adobe or FoxIt.  Using the API is there a way to account for the single object pages and recognize page orientation in order to draw the text as required for display in a viewer.

Thanks, Mike...

	Hi! You can check if there's rotation on the page and then you have to calculate... These links will give you an idea what to do: http://www.quickpdflibrary.com/faq/image-rotation-can-it-be-an-angle-like-60.php http://www.quickpdflibrary.com/faq/a3-stamping-rotation.php http://www.quickpdflibrary.com/help/quickpdf/PageRotation.php Cheers, Ingo

	What is the direction of rotation? Appearance is 90 degrees clockwise, top of the page at 3oclock. When I ran the following command it returned 270. int pr = qp.PageRotation();

	After QP.SelectPage(i) add a call to QP.NormalizePage(0); This will reset the page rotation to 0 so that you can safely add Annots an DrawText commands. Andrew.

	Hi! "What is the direction of rotation?" Rotation 0 means 12 o'clock... and it goes clockwise (right): Rotation 90 means 3 o'clock, 180 means 6 o'clock and 270 means 9 o'clock. Rotation 360 isn't possible 'cause that's again 0 and 12 o'clock ;-) Regarding your issue rotation 270 means that the page was mirrored. Cheers, Ingo

	We receive a lot of PDFs produced by scanners and some by fax machines. It is my understanding that the scanners produce the PDFs based on templates. Typically, one for B&W and one for Color. What is the advantage of using templates to produce PDFs that use color inversion, rotation, or mirroring of the scanned images? Thanks, Mike...
