The S-Pen is a pretty unique piece of hardware, especially on the latest generation of Note devices such as the Galaxy Note II and the Galaxy Note 10.1. However, the software for S-Pen is a little lacking. There are a number of fun drawing applications and other fun apps. However, there aren’t many killer S-Pen apps. Now, there is an image editing app optimized specifically for S-Pen.
XDA Forum Member lschiedel released a beta for an image editing application designed specifically around S-Pen functionality. As lschiedel explains:
Anyway, the app is a Photo Editor with paint tools, filter tools, and multiple floating layers including Image Layers, Text Layers, and Vector Layers.
The SPen support includes hover emulating moving the virtual mouse (a float brush icon that is see through when trimming layers) and uses the button on the pen to emulate left button/right button by click, letting you change from fore-ground color to back-ground color, as well as toggle between trimming layers by brush and untrimming layers by brush.
It supports large heap (meaning huge multi-mega-pixel images).
It has an image surface on the left, a toolbar on the top right, and a scroll pad/mouse pad on the bottom right.
It only needs some more icons and a little more debugging.
So for those who enjoy photography, image editing, and activities like these, this could be an extremely useful application. This is, of course, an open beta, so users will likely see some bugs here and there. Reporting them is generally helpful, so please report all you find.
