Description: Inkscape cannot create Quadratic Bezier curves without modifying XML but it can display them They are an overlooked SVG tool and easier to work with than the default Bezier curvesSection 1 Six quadratic Bezier curves A simple quadratic curve can be created with a starting point the letter q a control point and and ending point If the control point is midway between the start and end you get a nice symmetrical curve For example in a path tag use this d attributedm0100 q5050 1000Section2 Same thing but the starting point is on top and ending point is on the bottomSection 3 a A simple quadratic Bezier curve b To create repeating curves you can use a shortcut syntax which requires the letter q only once followed by a set of coordinates The q is implied between each coordinate c This can be repeated as many times as you likeSection 3 a To create two curves where the second curve is a reflection of the first curve you can use a further shortcut Just specify the letter t followed by a coordinate b horizontal cYou can repeat this for a longer curveSection 4 This writing was created only with quadratic Bezier curves It contains only the curves on this page scaled down and appended to each other to make a single pathInkscape will allow you to read files with quadratic Bezier curves and in some cases you can move them and they remain quadratic But modifying of them may cause Inkscape to turn them into cubic Bezier curves which is unfortunate because the syntax of quadratic Bezier curves is shorter and easier to work with
