The fill settings are displayed by clicking the icon next to the name of the selected shape layer or by pressing in the Tool Options panel and switching to the Fill Shape tab. The parameters will be applied to the selected shape.
No Fill . The created shape will be transparent.
Color Fill . The created shape will be filled with one color.
To choose a color bring the cursor over the spectral line (the cursor takes the form of a pipette) and click on the desired color.
The rectangular plate below indicates the selected color. Double-click on it to open the color selection dialog. The recent colors are displayed in the adjacent fields to the right.
Gradient Fill . The created shape will be filled with the selected gradient.
You can specify gradient colors using the gradient line. Click on the gradient line to create a color point. You can adjust the color and opacity of any point by double-clicking on it.
Also, you can fill the shape with a gradient using the Gradient Fill tool. Select the tool from the Toolbar and apply it to the shape layer. The settings can be adjusted using the Gradient tool parameters or using the Fill Shape parameters.
Reverse . The button reverses the order of colors in the gradient fill.
Dithering check-box. Activate the check-box to make the gradient smoother and reduce the number of stripes.
Aligned check-box. If the check-box is enabled, the gradient is aligned to the shape and moves appropriately with it. If the check-box is disabled, the gradient is aligned to the document and doesn't move when dragging the shape. You can scale the gradient by turning the check-box on/off.
Smoothing (0-100). The parameter makes the gradient smoother by smoothing the transitions between the individual colors and shades of colors.
Opacity (0-100). The parameter is common to both fill types and sets the overall fill opacity: the lower the value, the more pale and transparent the shapes are on the selected layer.
To outline the selected shape, configure the settings in the Stroke tab.
