No worries i figured it out, I reverted from Stock to LauncherPro with HomeSwitcher and it's now sorted :)

Think this is a know bug. Use the forum search button and you should find an answer hopefully.

A forum search brought up no answers for me (apart from the erroneous and unreliable 'switch between launchers' one). I would use LauncherPro all the time and completely abandon the default one if only it displayed wallpapers correctly (i.e. showing the whole picture, instead of zooming in on the top two thirds)! Using Home Switcher didn't fix the problem either. :)

There is 'wallswitcher' on the marketplace that did a better job of setting the background, just point it at a folder with your backdrop in, it did the best job so far of not zooming in too much..

I think the issue is LP's rotation code, the display is actually a 1024 * 600 (H x W), and for scrolling purposes, you do need (as mentioned, twice the width), so for portrait you need a 1024*1200 image in theory for 1:1 perfect backgrounds, but when in landscape, you need a 600 * 2048 (H x W) image using the same rule..

So to support both, you really should have a 2048 * 1200 image, and it should 'cut' the right section out according to orientation, but I don't think LP takes this into account properly... I'm going to try making various size images up, and use LP and then Wallswitch, and see which regions of the image are used..

Interesting comment. Thanks!

Did you do any testing?

Did you do any testing?

Being a nice lazy day today, I've started doing some testing, and have sussed it out..

1. The first tip is to use 'Wallswitch' available free on the marketplace, This preserves all the detail in the image, using the 'Wallpapers->Gallery' menu option to select/crop an image just ends in a very low quality image..

2. Always set the wallpaper in portrait mode, and in Wallswitch options set it's processing method to 'crop' if you want to ensure no black bars. If the image is the perfect ratio, none of this matters..

3. The perfect image aspect ratio/size is 1200*1024 (WxH), which is exactly what is reported for Android devices (Twice Screens Native Width X Screens Native Height), everything is referenced from portrait mode (600x1024)..

4. In Landscape, It obviously takes the top 58.5% of the image (600 pixels of 1024), but it doesn't seem to do a 'twice the width' scroll thing, it's less then that, it does seem if you use 1200 Wide, you get pretty much as sharp an image as you'd expect..

5. Setting LP to 'disable wallpaper scrolling' is nearly pointless, it will just stay on the centre part of the image, it won't resize it in anyway..

I suspect that it's an android thing amongst other stuff, really the launcher needs to take 2 images, one for portrait, one for landscape, otherwise whichever way you do it, you are going to get large chunks cropped when you switch orientation..

So to sum up

1. Use 'Wallswitch' , free on the marketplace, Point it at a folder with your Wallppaper(s) in it, and you can set it to auto-switch, or not..

2. Image sizes should be 1200x1024 (WxH) or any ratio of that as long as it's bigger (the ratio is 1.172:1), so for example in you have a 1600 pixel image width, multiply that by 1.172 and the image hieght should be 1875..

I'm off to make a few wallpapers now!
