Vector Graphics, What's the coordinate System?

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

   I have lines that I want to draw to pdf pages at specific coordinates.  Can someone explain what coordinate system the parameters are for DrawLine?  I can call Height and Width on the page but not sure if that gives me the same coordinate system as DrawLine uses.  Does SetMeasurementUnits have any effect on either Page Width/Height and/or DrawLine?  I am perplexed on how the coordinate system works with DrawLine.

TIA for the Help.

	Please have an eye on SetMeasurementUnits and SetOrigin. If there are functions which doesn't work with SetMeasurementUnits then you can read this in the descriptions. Here's the online reference: http://www.debenu.com/docs/pdf_library_reference/FunctionGroups.php Here's the developer guide: http://www.debenu.com/products/development/debenu-pdf-library/help/developer-guide/ Cheers and welcome here, Ingo

	Thank you for the response. SetOrigin was my issue. I assumed all the coordinates started in the upper left of the page. However, that is not the default and you have to explicitly set it to the upper left.
