Get Page Size

Is there a way to get the page height of a diagram.

When FCX displays its page markers, it queries either the default printer or the "PreferredDevice" to determine how to break the document up visually into sections.

Since we print on large format printers, these diagrams need to print on one page(34x100), and still be legible.  Many times there are branches which are border aligned that exceed the page height.  What I need to do is calculate the height of the branch and how much it exceedes the page height and split it up into smaller branches that are laid out centrally.

Thanks,
Alan

It seems the control keeps the page width and height in internal fields, so we can expose them as properties in the next release. Or you could calculate them yourself using this formula:

pageWidth = (long)(physicalWidth / (printerDPI / screenDPI));
pageHeight = (long)(physicalHeight / (printerDPI / screenDPI));

That will let you know the page width in screen pixels. Use the GetDeviceCaps Windows function on the printer HDC and the screen HDC to find out the physicalWidth/Height and DPI values.
