Re: [flexcoders] Absolute Sizing

[Daniel Freiman]

I've seen this issue and didn't figure it out (although it was a lower priority so I doubt I spent too much time on it).  If anyone wants to clarify what screenDPI actually means I'd be interested as well.  Right now it seems like a constant equal to 72.

Hi all -Does anyone know a strategy for creating an application window sizethat is an absolute size in inches (vs pixels) independent of screensize or reslution?My goal is to simulate one of these new UMPC devices with a 7 inch
screen, then compare the visual output to a 9 inch screen device -this simulation needs to run on whatever the client is running.My problem is that Capabilities.screenDPI is not returning a usefulvalue.
Example: on my laptop with 15 inch screen (12 inch horizontal, 9 inchvertical) is set to 1280x1024. Simple math tells me that I have 106.7pixels for each horizontal inch of screen, and 113.8 pixels per inch
of vertical. Skipping the math, I end up with a layout of 6.1x3.4inches for my 7 inch device, which (via pixels per inch) gives a pixelresoultion of 651x353. And, this works pretty well when actuallymeasured with a ruler.
However - Capatilities.screenDPI tells me that I have 72 pixels perinch (at least the docs say that dots = pixels).. in other words,using the screenDPI figure results in a completely missized window.
Is there a better way?thanks!david buitenveld--Flexcoders Mailing ListFAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt
