Edit Shapes Tool

shape-edit tool

The shape editing tool is for editing vector shapes. In Krita versions before 4.0 it would only show up in the docker when you had a vector shape selected. In Krita 4.0, this tool is always visible and has the Shape Properties docker as a part of it.

You can access the Edit Shapes tool by clicking on the icon in the toolbox, but you can also access it by pressing Enter when in the Shape Selection tool and having a shape selected that can be most efficiently edited with the edit shapes tool(Right now, that's all shapes but text).

On Canvas Editing of Shapes

As detailed further in the Tool Options, there's a difference between path shapes and specialised vector shapes that make it easy to have perfect ellipses, rectangles and more.

Path Shapes

Path shapes can be recognised by the different nodes they have.

Paths in Krita are mostly bezier curves, and are made up of nodes. For straight lines, the nodes are connected by a line-segment and that's it. For curved lines, each node has a side handle to allow curving of that segment using the cubic bezier curve algorithm.

What that means, in short, is that moving the side handles into a given direction will make the segment curve in that direction, and the longer the line of the node to the side handle, the stronger the curving.

Selecting Nodes for Editing

You can select a single node with left mouse button, they will turn bright green if selected.

left mouse button+Shift on unselected nodes will add them to a selection.

left mouse button+drag will make a selection rectangle. All nodes whose handles are touched by the rectangle will be selected. This combines with left mouse button+Shift above.

Selected Nodes

You can add and remove side handles from a selected node with left mouse button+Shift.

Krita has several node-types that allow you control the side handles more efficiently. These are the corner, smooth and symmetric modes.

Represented by a circle, the corner type allows you to have handles that can point in different directions and have different lengths.
Represented by a square, the smooth type will ensure a smooth transition by always pointing the handles into opposite directions, but they can still have different lengths.
Represented by a diamond, the symmetric node will force handles to always point in opposite directions and have the same length.

left mouse button+Ctrl on a selected node will cycle between the node-types.

del will remove the selected node.

Selected Segments

Segments are the lines between nodes. Hovering over a segment will show a dotted line, indicating it can be selected.

You can left mouse button and drag on a segment to curve it to the mouse point. Clicking on different parts of the segment and dragging will curve it differently.

Double left mouse button on a segment will add a node on the segment under the mouse cursor. The new node will be selected.

Other Shapes

Shapes that aren't path shapes only have a single type of node: A small diamond like, that changes the specific parameters of that shape on-canvas. For example, you can change the corner radius on rectangles by dragging the nodes, or make the ellipse into a pie-segment.

Tool Options

The tool options of the Edit Shapes Tool change depending on the type of shape you have selected. With the exception of the path shape, all shapes have a Convert to Path action, which converts said shape to a path shape.

Path Shapes

Path shapes are the most common shape and can be made with the following tools:

Node Editing
Edit the nodes.
Corner Point
Make the selected node a corner or cusp. This means that the side handles can point in different directions and be different lengths.
Smooth Point
Make the selected node smooth. The two side handles will always point in opposite directions, but their length can be different.
Symmetric Point
Make the selected node smooth. The two side handles will always point in opposite directions, and their length will stay the same.
Insert Point
Insert a new node into the middle of the selected segment.
Remove Point
Remove the selected node.
Line Segment Editing
Edit line segments between nodes.
Segment To Line
Make the current segment a straight line.
Segment To Curve
Make the current segment a curve: It'll add side nodes for this segment to the nodes attached to it.
Make Line Point
Turn the selected node into a sharp corner: This will remove the side handles.
Make Curve Point
Turn the selected node into one that can curve: This will add side handles to the node.
Break at Point
Break the path at this point.
Break Segment
Break the path at the selected segment.
Join with Segment
Join two nodes that are only attached on one side with a segment.
Merge Points
Merge two nodes into one, if the nodes are adjacent or if both nodes are only attached on one side with a segment.

Rectangle Shapes

rectangle tool

Rectangle shapes are the ones made with the Rectangle Tool. It has extra options to make rounded corners easy.

Corner radius x
The radius of the y-axis of the corner curve.
Corner radius y
The radius of the y-axis of the corner curve.

Ellipse Shapes

ellipse tool

Ellipse shapes are the ones made with the Ellipse Tool.

The type of ellipse shape it is.
An arc shape will keep the path open when it isn't fully circular.
A pie shape will add two extra lines to the center when the shape isn't fully circular, like how one cuts out a piece from a pie.
A cord shape will add a straight line between the two ends if the path isn't fully circular, as if a cord is being strung between the two points.
Start Angle
The angle at which the shape starts.
End Angle
The angle at which the shape ends.
Close Ellipse
An action to quickly make the ellipse fully circular.

Star Shapes/Flower Shapes

Star shapes and Flower shapes are dragged and dropped from the Add Shape Docker.

Whether the shape should be handled as a polygon(like a pentagon or hexagon) or a star shape.
How many corners the shape should have.
Inner Radius
The position of the inner node relative to the center.
Outer Radius
The position of the outer node relative to the center.

Spiral Shapes

Spiral shapes are the ones dragged and dropped from the Add Shape Docker.

The type of spiral
A round spiral.
A blocky square spiral, like a greek ornament.
The number that indicates how fast the spiral spirals inwards. A high number will mean it is a perfect circle, a low number means it spirals inward very quickly.
Whether the spiral goes clockwise or counter clockwise.
