How to Draw on Paint Net

Revision Date: fourteen April 2021

Line/Curve Tool
O once

This tool is used to describe lines and curves. These two abilities are grouped into a single tool because a line is really a perfectly straight curve. In other words, this tool always draws curves, where a straight line is a subset involving no actual curvature.

Drawing a line is straightforward: click where the line begins and drag the mouse arrow to the end point. Releasing the mouse button ends the "cartoon" phase.

Notation

Using the Left Mouse button renders the line with the Primary color.  Using the Right Mouse Button renders the line in the Secondary color.

When the drawing phase is concluded, four control nubs appear on the line and the four-way move icon appears just off the end signal of the line.

Line/Bend Handles

The Control Nubs and Move icon pulsate to make them easier to distinguish.

If a single, straight line is desired, press the Enter fundamental or click the Finish push in the Tool Bar to commit the line to the sail.  Drawing elsewhere on the canvass finishes any previous line and starts a new i.

Tip

Holding down the Shift key before releasing the mouse button constrains the line to angles that are multiples of xv degrees, east.g. 0°, 15°, 30°, 45° 60° and and then on.

If a curve is desired, drag the control nubs to a new location by clicking and dragging.

Moving a Line/Curve

Before a Line/Curve is committed to the canvas, it can be moved anywhere on the sail. Click and elevate the pulsing four-arrows-in-a-foursquare icon (see diagram below) using the Left Mouse Button to reposition the Line/Bend.

The keyboard pointer keys ↑ ← ↓ → can likewise exist used to move a Line/Curve.  A single fundamental press moves the object by one pixel in the direction of the arrow. Simultaneously holding the Ctrl key moves the object past 10 pixels per pointer key printing.

Rotating a Line/Bend

Before a Line/Curve is committed to the canvass, it can be rotated about its geometric middle.

Rotate the Line/Bend about the eye using the Correct Mouse Button. Click and drag to rotate.  Every bit a visual guide that rotation is possible, the mouse pointer will turn into a double headed pointer (see diagram).

Rotate Cursor

If the Shift primal is held down while rotating the angle of rotation is snapped to 15 degree increments.

The keyboard arrow keys ↑ ← ↓ → can also exist used to rotate a Line/Curve while the Right Mouse Push is held downwardly.

Committing a Line/Curve to the canvas

Commit a Line/Curve to the active layer and exit editing manner using any ane of these methods…

1. Press the Enter key
2. Click outside of the bounding box of the current Line/Curve.
3. Click Finish in the Tool Bar
4. Draw a new Line/Curve.

Curve Types

There are 2 icons in the Tool Bar for irresolute between Cubic Spline and Bézier curves.  These replace the Right click & drag that paint.net 3.5x used.

Curve Types

If the Left icon (Spline) is selected, the line volition be curved using cubic spline interpolation.  It will ever continue through each of the Control Nubs, even if the nubs are relocated or dragged off canvas.  When a nub is moved, the curve will be redrawn so that it always goes through the center of each Command Nub.

If the Right icon is selected (Bézier), a Bézier curve results.  With this curve blazon, the bend will extend from the first or origin Control Nub to the last or destination Control Nub.  The second and third Control Nubs modify the bend along its path. The curve will non necessarily touch either the 2d or tertiary Control Nub.  Some types of Bézier curves cannot be fatigued using the Cubic Spline type.

Bézier Curve

Tip

Switch between curve types by toggling between the two Bend Icons in the Tool Bar.  The curve will be reinterpreted based on the curve blazon and current location of the Control Nubs.

Brush Width, Line Fashion and Make full

Lines and curves are subject area to the Brush settings in the Tool Bar. Brush Width, Line Styles & Fill Blazon are all configurable.

Line/Curve Options

The Line/Curve can have different beginning cap, dash style, and end cap. The kickoff- and end-caps can be flat (normal), one of two pointer caput types, or rounded. The dash style tin can exist either solid or a combination of dashes and dots.

Line Styles

Using Brush Width & Line Styles lines like these can be drawn:

Example Lines

Lines and curves can be rendered using a Make full Type every bit specified in the Tool Bar.  This feature allows the line/curve to be filled with one of numerous patterns rather than a solid colour.

Fill up Styles

Fills utilizing a fill style volition make use of both the Primary and Secondary colors.

Antialiasing

In that location are ii antialiasing modes associated with the Line/Curve tool.

Antialiasing Modes

These settings make up one's mind whether the line is rendered in a clip-to-pixel manner or not.

The effect of antialiasing on lines

When Antialiasing is enabled, lines volition appear slightly thicker and smoother (upper example).

When Antialiasing is disabled, lines are rendered in solid pixels and appear more jagged and thinner (lower case).

Antialiasing can be switched on or off via the Tool Bar when the Text tool is agile.

Alloy Modes

Lines and curves tin be practical using a Blend Manner selected from the Tool Bar.  The line/curve will exist practical in accordance with the other parameters then reinterpreted as if the pixels were on their ain layer with the layer blend mode ready.
