Detailed Description

\qmltype Shear \nativetype QQuickShear \inqmlmodule QtQuick

Since: 6.9

Provides a way to shear an Item.

The Shear type provides a way to transform an \l Item by a two-dimensional shear-type matrix, sometimes known as a skew transform.

\qml Rectangle { width: 100; height: 100 color: "blue" transform: Shear { xFactor: 1.0 } } \endqml

This shears the item by a factor of 1.0 along the x-axis without modifying anything along the y-axis. Each point P is displaced by {xFactor(P.y - origin.y)} (the signed vertical distance to the \l{origin} multiplied with the \l{xFactor}). Setting the \l{yFactor} shears the item along the y-axis and proportionally to the horizontal distance.

Since the default origin is at {(0, 0)}, the top of the item remains untransformed, whereas the bottom is displaced 100 pixels to the right (corresponding to the height of the item.)

This code is equivalent to the following:

\qml Rectangle { width: 100; height: 100 color: "blue" transform: Shear { xAngle: 45.0 } } \endqml

Note: If both {xFactor}/{yFactor} and {xAngle}/{yAngle} are set, then the sum of the two displacements will be used.
