贝塞尔曲线工具

toolbeziercurve

You can draw curves by using this tool. Click the mouseleft to indicate the starting point of the curve, then click again for consecutive control points of the curve.

Krita will show a blue line with two handles when you add a control point. You can drag these handles to change the direction of the curve in that point.

On a vector layer, you can click on a previously inserted control point to modify it. With an intermediate control point (i.e. a point that is not the starting point and not the ending point), you can move the direction handles separately to have the curve enter and leave the point in different directions. After editing a point, you can just click on the canvas to continue adding points to the curve.

Pressing the Del key will remove the currently selected control point from the curve. Double-click the mouseleft on any point of the curve or press the Enter key to finish drawing, or press the Esc key to cancel the entire curve. You can use the Ctrl key while keeping the mouseleft pressed to move the entire curve to a different position.

While drawing the Ctrl key while dragging will push the handles both ways. The Alt key will create a sharp corner, and the Shift key will allow you to make a handle while at the end of the curve. mouseright will undo the last added point.

工具选项

4.1.3 新版功能:

自动平滑曲线

Toggling this will have nodes initialize with smooth curves instead of angles. Untoggle this if you want to create sharp angles for a node. This will affect curve sharpness from dragging after clicking.

角度捕捉增量:

The angle to snap to.

Activate Angle Snap

Angle snap will make it easier to have the next line be at a specific angle of the current. The angle is determined by the Angle Snapping Delta.
