[Nexus 7 Themes and Apps] styckx:
I see wallpapers asked for a lot so I figured I'd write up a easy tutorial for people on how when they find great pictures to properly frame it out to work as you imagined it. I think among those less tech savvy and familar with image editing struggle with this so I'm going to attempt to help them here. :) We all know the built in wallpaper functionality of Android isn't exactly the greatest thing ever and usually does a better job of frustrating you more than it does actually getting the wallpaper you picked framed how you imagined it.. There are two great apps in the market that help makes this easier. Simple Image Wallpaper and MultiPicture Live Wallpaper...The problem with both is that they are basically cropping it for you to the correct aspect ratio using a center average. This means unless the wallpaper you picked out has the `cool part' dead center, it will still probably look terrible. For this demonstration I will be using Simple Image Wallpaper.

Secondly you're going to need a paint program that allows you to set custom aspect ratios with the selection tool/crop tool. Since this is a demonstration for the general public we're going to do this with a free program anyone can download. Paint Dot Net.

Recap.. Items needed

1. Simple Image Wallpaper

2. Paint Dot Net

3. Wallpaper

I linked an example wallpaper I will be using in this demo in recap item #3. Below is what this wallpaper looks like using Simple Image Wallpaper without any cropping.

As you can see it cropped the center portion for you. You could go into any paint program and just cut out the glass and plop it on your screen but the problem is that it probably still won't fit how you imagined it because you cut the picture in an aspect ratio that is incorrect for the Nexus 7 (or any device) screen and the program will still have to stretch it and squeeze it onto the screen. So.. Assuming now you installed paint.net open it up and load the wallpaper I provided. Once it is opened select the rectangle tool, then change it to fixed ratio and enter in 800x1280 as shown here.

Now using your left mouse button click and drag on the image. The size you make this rectangle doesn't matter since it is always in the correct aspect ratio for your Nexus 7 screen. This will translate to your screen EXACTLY as you see it inside this rectangle. You probably tried a few times to perfectly draw out the rectangle to surround the glass perfectly but don't worry it doesn't even matter if you drew it off the glass.

Let's say this is what your screen looks like.

To `fine tune' this select the `Move Selection tool"

With this tool selected you should see dots appear around the rectangle. These are `drag points'.. Shift-Click, drag, and it will re-size the rectangle while keeping the correct aspect ratio. You only want to use the corner drag points for this to keep the aspect ratio correct. You can also click and drag inside the rectangle and position it around. Once done you should be able to perfectly frame the glass. Once you are done crop the photo, save it, copy it to your device and load it up in Simple Image Wallpaper in the Portrait selection.

Perfection

Use the same concept to now do your landscape picture (the image selection that is above Portait in Simple Image Wallpaper) except instead of cropping to 800x1280, you are now going to crop 1280x800.

Enjoy!
