Step 1. First use the Sharp mode to define color
zones:
Blue zones are the parts of
the image that must be kept. The points in this area have
Transparency = 0%.
Red zones are the parts of the
image that will be deleted. The points in this area have
Transparency = 100%.
Green zones are a "transition
border" between the kept and cutout areas. The points in these zones
have different Transparency values (between 0 and 100%).
Step 2. Use the following tools to edit the color zones:
To edit the blue zones, use
and , for red
zones - and ,
for green zones -
and .
Adjust the stroke width by changing the value of the Brush
Size parameter on the Settings panel.
Use the Green Zone Width parameter on the Settings
panel to change the size of the green zones. The higher the value of the
parameter, the wider
the green transition border is. This parameter influences
only the automatically generated green zones and changes their size on
their full length. To edit the green zones more precisely, use the corresponding
pencils from the Toolbar.
Step 3. If needed, adjust the
Sensitivity parameter on the Settings panel. This
parameter influences the amount of details revealed in difficult areas.
The higher the value of the parameter, the more semi-transparent details
are visible.
Step 4. Start image processing by clicking on .

mode, click on
