Is there any way to flip the rulers over so that they measure from the bottom left corner?

I'm using the measuring tools in Adobe Acobat Professional version 8.1 & 9... All of the XY coordinates on the PDFs I'm measuring have 0:0 located in the bottom left corner... the Adobe rulers have 0:0 set to the top left corner. Any help would be greatly appreciated.

My Product Information:
Acrobat Pro 8.1, Windows

May be a little late but you need to translate the device space coordinates ( ruler return) to user space coordinates.

ASFixedPoint userPointAS;
AVPageViewDevicePointToPage( view, devicePoint.X, devicePoint.Y, &userPointAS );

Thanks very much for replying ecoyne.

I'd really like to give this a try, but I'm not sure how to translate the device space coordinates... I didn't see any options for this in the measuring or units&guides preferences... am I looking in the right place?Many thanks.

@cd7698 - the simple answer is you can't. The rulers are like that because the position of objects on a PDF page are internally referenced from that corner, just as they are in Word, etc.

The reply from ecoyne is not relevant - he/she is talking about the idea a plugin written in C++ could access the low-level data and do something with it, but that won't affect the rulers you see on screen nor the way Acrobat's measuring tools work.

Yes it was the rulers on screen that I had hoped to affect.

Oh well, I guess what I'm asking for just isn't possible. Thank you both anyway.
