It is always nice to add spice to stuff that you have to view daily. This is the reason wallpapers exist, but even changing wallpapers gets boring after a while. WAlpha is a free tweak for jailbroken iOS devices, that adds a small degree of customization to the wallpaper. It allows you to reduce the wallpaper’s alpha value, effectively dimming it out – roughly the same effect you see within Spotlight search. It is already possible by default to change the size and placement of your wallpapers in iOS, and that can give you some customization. The functionality offered by WAlpha should be considered an extension of this minor customization capabilities. Of course, you can edit the whole image in some other app, reduce its brightness and then apply it as a wallpaper, but why go through all that trouble when you have got WAlpha, which does the stuff with a simple slider.
If you don’t already know that, the alpha value in photo editing terms is somewhat equivalent to the brightness coefficient of an image file. Increasing or decreasing the alpha value changes the visibility of a photo, and might even leave it looking a bit translucent (only happens for some images, and that too only when the alpha is just at the right value). The screenshots you see above have been taken after changing the alpha value of iPhone’s default wallpaper. The one on the left shows the wallpaper with alpha value set to approximately 50%, while in the one on the right, the value has been set to zero.
Doing so is easy. Once you have the tweak installed on your iPhone, iPad or iPod touch, go to the Settings menu of your device and select it from under the Extensions tab.
The tweak’s settings consist of nothing more than a simple slider that can be dragged to adjust the current wallpaper’s alpha value. The more you move the slider to the left, the dimmer the wallpaper will get. Note that the new alpha value will only be applied after you flip through the screens at least once. This also gives users a chance to admire their handiwork, and gauge the true change taking place with the change of an image’s alpha. If you want a normal wallpaper, just go to the tweak’s menu and toggle off the Enable button.
A pretty simple functionality, but it does make the icons on the Springboard a tad more prominent.
