Using the Freehand Selection Tool you can draw on your page to define a pixel selection based on a freehand-drawn line, a straight-edged polygon or an area created by a line that magnetises to image edges.
Freehand selection in the process of being drawn. To draw a pixel selection:
From the Pixel Persona, select the Freehand Selection Tool.
From the context toolbar, choose a selection Type (from Freehand, Polygonal or Magnetic). Do one of the following:
With the Freehand type:
Drag to draw a freehand line that forms a selection on release.
With the Polygonal type:
Single-tap to define corners of a straight-edged polygon. Tapping back on the starting point converts the polygon to a selection.
With the Magnetic type:
Single-tap directly over strong edges in your image. Magnetic nodes will be laid down that will snap to those edges.
Adjust the Feather slider for a softer selection edge.
