On Macintosh and microsoft Windows, Inpaint is a graphics program for photo retouching and object removal.
With the use of streamlined semi-automatic tools and mechanisms, Inpaint concentrates on photo editing. The software comes with a tool that is comparable to the Content-Aware Healing Brush tool in Adobe Photoshop CS5. To achieve a seamless repair of an image, the tool works similarly to Healing Brush by attempting to replace the faulty or damaged textures with good textures from other locations.
Photo retouch and restoration tips:
The pixels close to the area boundary are used by Inpaint to recreate the chosen image region.
Inpaint uses the surrounding pixels to reconstruct the selected area. The contribution area allows you to control the pixels used to fill the selection area. Read the tutorial
The Guide Lines tool is for complex images where the object you want to remove has two different backgrounds. Read the tutorial
Instead of trying to delete everything at once, try selecting and pressing the "Delete" button one by one, one after the other. Every Inpaint process is unique, so you'll get a slightly different result every time you press the "Erase" button.
