The opposite of pixel doubling? From VGA to QVGA?

[Brad Isaac]

Hi,

I am developing a PPC app. Currently, I'm building it for VGA
devices. But wanted to plan a QVGA version too. How do you all
handle the switching from VGA to QVGA?

Thanks!

VS 2005 and onwards should handle this by magic. In terms of calculating the
form factor for custom UI (GDI), you will need to reverse your calculation ie:

[value] * Dpi.X / [designTime DPI]

So essentially there is no difference assuming you are using variables for
[designTime DPI]. So [designTime DPI] might be 192DPI where normally you
design at the lowest level 96DPI.
