Left Toolbar > Create Nodes > Shapes
The Create Shapes node allows you to create shapes like circles, rectangles and Bezier splines. Each shape has its own properties: position, rotation, color, stroke width, etc.
The Shape node takes as input the lock image. In the shapes node a Bezier spline is drawn around the lock. The Bezier spline is rendered using the lock image as fill, and a red stroke.
On the left toolbar choose Create Nodes > Shapes. >
Drag the Shapes icon into the Node Graph.
Connect an input image if you need a image fill.
Draw the shapes in the image viewport.
Images that can be used to use as fill for the shapes.
The drawn shapes, with fill and stroke applied.
The Shapes node supports 3 types of shapes:
A circle with center and radius properties.
A rectangle with center, sizex and sizey properties.
A shape composed of control points and Bezier segments.
If checked, the image is generated.
If checked, the shapes are displayed in the viewport with lines and points.
Defines the background color.
Defines the background opacity.
The shapes list shows all the shapes that will be rendered. The order of the shapes define the rendering order, so the top most shape will be rendered first.
Clicking a shape in the list makes it the current shape. The current shape is displayed in bold font. The properties of the current shape are displayed and edited in the Shape group.
Moves the current shape up or down in the list.
Delete the current shape.
Converts the current shape to Bezier spline.
Duplicates the current shape.
The shape properties group displays the properties of the current shape.
The name of the shape.
If checked, the shape will be filled.
Fill combo box
Select the fill method.
Color: The shape is filled with a constant color.
Number: The id of the input image to be used as fill.
The color of the filling.
The opacity of the filling.
If checked, the stroke of the shape will be rendered.
The color of the stroke.
The opacity of the stroke.
The width in pixels of the stroke.
The shapes node adds a toolbar to the left toolbar panel when active.
Allows you to create circles in the image viewport using the mouse.
LMB press defines the center, drag to define the radius and release to accept.
RMB click cancels the creation of the circle.
Allows you to create rectangles in the image viewport using the mouse.
LMB press to define the center, drag to define the radious and release to accept.
RBM click cancel the creation of the rectangle.
Create Bezier spline
Allows you to create Bezier splines using the mouse.
LMB press defines the position of the control point, dragging defines the handle of the control point, and release finishes the control point.
RMB stops the creation of the Bezier spline.
If the Bezier spline is created with less than two control points it is deleted on stop creation.
Allows you to translate, rotate and scale shapes using the mouse and the transform manipulator.
A Transform Manipulator is shown in the image viewport.
Allows you to edit shapes using their control points.
The shapes node adds a toolbar to the top toolbar panel when active. This top toolbar is updated when the left toolbar tool changes, or when a new current node is activated.
Allows the user to create a new Bezier spline. The new Bezier spline will be added to the current shape.
Insert spline knots
Allows the user to click a Bezier segment to insert a new control point at that specific location.
;Delete: Allows the user to delete the selected control points. If all the control points of the spline are selected, the spline shape is deleted.
Break spline knots
Allows the user to break the selected control points. If the spline is closed, by breaking a control point it becomes an open spline. Breaking control points can create multiple Bezier splines.
Join spline knots
Allows the user to weld control points to connect open segments and splines.
Connect spline knots
Allows the user to connect the open ends of one or two Bezier splines that belong to the same shape. Connecting the two open ends of a single spline effectively closes the spline.
Reverses the selected splines. All the knots of the spline have to be selected for the reverse to take action. Double-click the spline to select all knots.
Allows the user to pick an existing shape. The shape will be converted to a Bezier spline and added to the current shape. The selected shape will be deleted from the shapes list.
