The stamp is a tool for painting with pictures.
The accompanying dialog allows to set the Intensity for that tool.
The menu Stamp enables you to load or save stamps. It is possible to use the current lasso as stamp, too.
All picture files in the folder Stamp in the folder Defaults in the PhotoLine directory are listed in a combo box. This way you have quick access to them. These picture files are quite normal, but the PLD file format is preferred. A picture file may have more than one layer. In this case the layers are used alternately.
Minimum Brush Distance controls the distance between two stamps when dragging the mouse.
