[HOWTO] WallPaper Cropping guide for A101 and A70
Note: This is a work in progress.
Note: All Image manipulation is done with GIMP.
Note: This guide is mainly for the A101 but can also be applied for the A70.
I was getting sick of not be able to take a good picture and use it as a wallpaper so that it looked good. I know there is an alternative "MultiPicture Live Wallpaper" but that thing is a memory hog.
So I came up with this picture it's a PNG of 1200x1024. The different grids are the following sizes.
- Blue: 8px
- Green: 16px
- Red: 32px
- White: 64px
When this is set as a wallpaper we can finally see what is happening to the image.
Here are the screenshots for the 5 screens of the Stock Launcher of the Archos 101.
Since the status bar can not be hidden on the Stock Launcher we loose 32px at the top and on the right with the soft buttons we loose 40px. When positioned on the first screen we have a good view of the top left corner (1024x600) of the reference picture.
Now lets get to work with this picture below.
So what do we need to do. The result must be an image with a size of 1200x1024 for the A101 and 960x800 for the A70 where only the top 600px (A101) 480px (A70) will be visible in landscape mode.
- Scaling the image to a height of 600px and keeping the aspect in mind. The result is a picture of 960x600
- On the bottom add a 424px black border.
- On both sides add a 120px black border.
and the result is
And the screenshot to prove it works.
This was tested with the Stock Launcher and ADW.Launcher.
So this worked out because the original picture has a black background. So here is the solution for other pictures.
I made a multi layer xcf file with GIMP to address the problem. You can download it here
for the A101 and here
for the A70.
- Open WallPaper_cropping.xcf in GIMP.
- Select the "Background" layer.
- File -> Open as Layer -> select the picture you want to crop.
- Scale the layer to 1200px width and keep the aspect correct.
- Position the layer so that the visible part looks good.
- Turn visibility on/off so that only the layers "Background:, "The Picture", "Black Not Visible Part" are turned on.
- Save the image as PNG with option "Merge Visible Layers"
- Send to archos and apply as wallpaper with the Crop Wallpaper app and use the "Overall" button.
This is all for today. Next We'll see if we can do something with extending the background instead of cropping it.
