Eraser

This tool allows you to "erase" pixels (makes the effected area transparent)

Click on Eraser image\ppEraser.gif on the Tools bar.

Select a brush shape and style from the "Brushes" dialog (see Brushes). Depending on the brush chosen you can erase pixels in a variety of ways, sometimes getting a complete erasure and sometimes, with the use of the Opacity box, a faded effect.
