Hi

I have a background image of 2318x1594px

I load it and copy the part I need to use depending on device size.

For my PC on Windows, it's good in window and full screen mode.

On a Mac and iOS devices, the picture is truncated !

On iOS (iPad, iPod Touch and iPhone), the size is 579x398 after LoadImage.

On Mac OS (iMac and Mac Book Pro), its size is 1159x797.

Why AppGameKit don't load the image correctly ?

I'm using AppGameKit 108b19

Are you using the default percentage system? Try using SetVirtualResolution(). Also, not all devices can use images that large. Not sure what happens in that case, your problem could be related to that. 1024x1024 is the recommended maximum size for mobile devices. Not all graphics cards can handle images larger than 2048x2048 either.

maybe try this command and use power of 2 size textures.
SetResolutionMode( mode )
1 to use a high (native) resolution
0 to use a low (scaled) resolution

I'm using pixel mode et tried the two SetResolutionMode. Same problem.

I think it's a limit with graphic library. On mobile devices like iPhone or iPod Touch, I can understand, but why Mac and Windows don't have same capabilities ?

then maybe you are over the max. size limit that the graphics card can handle. else i would also expect the original image size
at native resolution mode.

there exist also a SetIntendedDeviceSize( width, height ) func.

It's not an OS problem. I would guess that your Mac can't handle an image larger than 2048x2048, due to limits in the graphics hardware.

It depends on the Open GL drivers.

on the Mac Book Pro Retina, I have don't think it's the hardware limits

I suppose we can't change it in AppGameKit interpreter without having bad surprises ?

So, if TGC can do it with AppGameKit 2, it would be great.

Sorry if I'm being stupid, but I don't get the "it's too large for the graphics card to handle" part. Surely if you can open an image larger than 2048 x 2048 normally, as in just opening a jpeg in a folder on your computer. Then why is this not possible in a game? Is it a forced limitation due to the fact that a game will obviously load many images?

It's Open GL - it treats all images as textures, and imposes a limit. This frequently 1024x1024, but will be 2048x2048 on some systems. As far as I can see the max is 2048x2048 on a Macbook, and must be a power of two.
