Setting the device's screen resolution


Setting the device's screen resolution

Postby Nic-Gun » Feb 14, 2008 @ 9:35am

hi there,

is it possible to change a device's resolution so it'll match my application's graphics?

currently i'm making a game using the 240x320 resolution, and then i wanted to import the game to a 480x640 resolution device without making new graphics.

will be waiting for your response. thanks.

Hi Nic-Gun,

It's not possible to change the resolution of a mobile device. You can use GAPI (which stretches 240x320 to 480x640), but it leads to a wide range of problems and isn't recommended.

I suggest scaling your resources 200% at load time for high-resolution devices, and make your application resolution aware.

if i'm scaling at load time, does it mean i need to create a new surface for the graphic i want to scale? won't it slow the loading process then?

and what about scaling at run time? which one is better?

by the way, which function should i use to create the new scaled object? thanks.

the Resize() works great. but can I get the resolution used by the device that's running my application?

I wanted to check the resolution used and then divide it bt 240x320 to get the desired scaling factor for the Resize() method.

I just found out that the default setting for config->width and config->height is 240x320 so I can't use that. any suggestion? thanks.

Hi Nic-Gun,

You can use GetWidth and GetHeight on the backbuffer surface to get the size of the display.
