| 95 | \class QTransform | - |
| 96 | \brief The QTransform class specifies 2D transformations of a coordinate system. | - |
| 97 | \since 4.3 | - |
| 98 | \ingroup painting | - |
| 99 | \inmodule QtGui | - |
| 100 | | - |
| 101 | A transformation specifies how to translate, scale, shear, rotate | - |
| 102 | or project the coordinate system, and is typically used when | - |
| 103 | rendering graphics. | - |
| 104 | | - |
| 105 | QTransform differs from QMatrix in that it is a true 3x3 matrix, | - |
| 106 | allowing perspective transformations. QTransform's toAffine() | - |
| 107 | method allows casting QTransform to QMatrix. If a perspective | - |
| 108 | transformation has been specified on the matrix, then the | - |
| 109 | conversion will cause loss of data. | - |
| 110 | | - |
| 111 | QTransform is the recommended transformation class in Qt. | - |
| 112 | | - |
| 113 | A QTransform object can be built using the setMatrix(), scale(), | - |
| 114 | rotate(), translate() and shear() functions. Alternatively, it | - |
| 115 | can be built by applying \l {QTransform#Basic Matrix | - |
| 116 | Operations}{basic matrix operations}. The matrix can also be | - |
| 117 | defined when constructed, and it can be reset to the identity | - |
| 118 | matrix (the default) using the reset() function. | - |
| 119 | | - |
| 120 | The QTransform class supports mapping of graphic primitives: A given | - |
| 121 | point, line, polygon, region, or painter path can be mapped to the | - |
| 122 | coordinate system defined by \e this matrix using the map() | - |
| 123 | function. In case of a rectangle, its coordinates can be | - |
| 124 | transformed using the mapRect() function. A rectangle can also be | - |
| 125 | transformed into a \e polygon (mapped to the coordinate system | - |
| 126 | defined by \e this matrix), using the mapToPolygon() function. | - |
| 127 | | - |
| 128 | QTransform provides the isIdentity() function which returns true if | - |
| 129 | the matrix is the identity matrix, and the isInvertible() function | - |
| 130 | which returns true if the matrix is non-singular (i.e. AB = BA = | - |
| 131 | I). The inverted() function returns an inverted copy of \e this | - |
| 132 | matrix if it is invertible (otherwise it returns the identity | - |
| 133 | matrix), and adjoint() returns the matrix's classical adjoint. | - |
| 134 | In addition, QTransform provides the determinant() function which | - |
| 135 | returns the matrix's determinant. | - |
| 136 | | - |
| 137 | Finally, the QTransform class supports matrix multiplication, addition | - |
| 138 | and subtraction, and objects of the class can be streamed as well | - |
| 139 | as compared. | - |

| 143 | \section1 Rendering Graphics | - |
| 144 | | - |
| 145 | When rendering graphics, the matrix defines the transformations | - |
| 146 | but the actual transformation is performed by the drawing routines | - |
| 147 | in QPainter. | - |
| 148 | | - |
| 149 | By default, QPainter operates on the associated device's own | - |
| 150 | coordinate system. The standard coordinate system of a | - |
| 151 | QPaintDevice has its origin located at the top-left position. The | - |
| 152 | \e x values increase to the right; \e y values increase | - |
| 153 | downward. For a complete description, see the \l {Coordinate | - |
| 154 | System} {coordinate system} documentation. | - |
| 155 | | - |
| 156 | QPainter has functions to translate, scale, shear and rotate the | - |
| 157 | coordinate system without using a QTransform. For example: | - |
| 158 | | - |
| 159 | \table 100% | - |
| 160 | \row | - |
| 161 | \li \inlineimage qtransform-simpletransformation.png | - |
| 162 | \li | - |
| 163 | \snippet transform/main.cpp 0 | - |
| 164 | \endtable | - |
| 165 | | - |
| 166 | Although these functions are very convenient, it can be more | - |
| 167 | efficient to build a QTransform and call QPainter::setTransform() if you | - |
| 168 | want to perform more than a single transform operation. For | - |
| 169 | example: | - |
| 170 | | - |
| 171 | \table 100% | - |
| 172 | \row | - |
| 173 | \li \inlineimage qtransform-combinedtransformation.png | - |
| 174 | \li | - |
| 175 | \snippet transform/main.cpp 1 | - |
| 176 | \endtable | - |
| 177 | | - |
| 178 | \section1 Basic Matrix Operations | - |
| 179 | | - |
| 180 | \image qtransform-representation.png | - |
| 181 | | - |
| 182 | A QTransform object contains a 3 x 3 matrix. The \c m31 (\c dx) and | - |
| 183 | \c m32 (\c dy) elements specify horizontal and vertical translation. | - |
| 184 | The \c m11 and \c m22 elements specify horizontal and vertical scaling. | - |
| 185 | The \c m21 and \c m12 elements specify horizontal and vertical \e shearing. | - |
| 186 | And finally, the \c m13 and \c m23 elements specify horizontal and vertical | - |
| 187 | projection, with \c m33 as an additional projection factor. | - |
| 188 | | - |
| 189 | QTransform transforms a point in the plane to another point using the | - |
| 190 | following formulas: | - |
| 191 | | - |
| 192 | \snippet code/src_gui_painting_qtransform.cpp 0 | - |
| 193 | | - |
| 194 | The point \e (x, y) is the original point, and \e (x', y') is the | - |
| 195 | transformed point. \e (x', y') can be transformed back to \e (x, | - |
| 196 | y) by performing the same operation on the inverted() matrix. | - |
| 197 | | - |
| 198 | The various matrix elements can be set when constructing the | - |
| 199 | matrix, or by using the setMatrix() function later on. They can also | - |
| 200 | be manipulated using the translate(), rotate(), scale() and | - |
| 201 | shear() convenience functions. The currently set values can be | - |
| 202 | retrieved using the m11(), m12(), m13(), m21(), m22(), m23(), | - |
| 203 | m31(), m32(), m33(), dx() and dy() functions. | - |
| 204 | | - |
| 205 | Translation is the simplest transformation. Setting \c dx and \c | - |
| 206 | dy will move the coordinate system \c dx units along the X axis | - |
| 207 | and \c dy units along the Y axis. Scaling can be done by setting | - |
| 208 | \c m11 and \c m22. For example, setting \c m11 to 2 and \c m22 to | - |
| 209 | 1.5 will double the height and increase the width by 50%. The | - |
| 210 | identity matrix has \c m11, \c m22, and \c m33 set to 1 (all others are set | - |
| 211 | to 0) mapping a point to itself. Shearing is controlled by \c m12 | - |
| 212 | and \c m21. Setting these elements to values different from zero | - |
| 213 | will twist the coordinate system. Rotation is achieved by | - |
| 214 | setting both the shearing factors and the scaling factors. Perspective | - |
| 215 | transformation is achieved by setting both the projection factors and | - |
| 216 | the scaling factors. | - |
| 217 | | - |

| 219 | operations: | - |
