<P>
<p>The <a href="QTransform.html#QTransform()"><tt>QTransform</tt></a> class specifies 2D transformations of a coordinate system.</p>
<p>A transformation specifies how to translate, scale, shear, rotate or project the coordinate system, and is typically used when rendering graphics.</p>
<p><a href="QTransform.html#QTransform()"><tt>QTransform</tt></a> differs from <a href="QMatrix.html"><tt>QMatrix</tt></a> in that it is a true 3x3 matrix, allowing perpective transformations. <a href="QTransform.html#QTransform()"><tt>QTransform</tt></a>'s <a href="QTransform.html#toAffine()"><tt>toAffine</tt></a> method allows casting <a href="QTransform.html#QTransform()"><tt>QTransform</tt></a> to <a href="QMatrix.html"><tt>QMatrix</tt></a>. If a perspective transformation has been specified on the matrix, then the conversion to an affine <a href="QMatrix.html"><tt>QMatrix</tt></a> will cause loss of data.</p>
<p><a href="QTransform.html#QTransform()"><tt>QTransform</tt></a> is the recommended transformation class in Qt.</p>
<p>A <a href="QTransform.html#QTransform()"><tt>QTransform</tt></a> object can be built using the <a href="QTransform.html#setMatrix(double, double, double, double, double, double, double, double, double)"><tt>setMatrix</tt></a>, scale(), rotate(), translate() and shear() functions. Alternatively, it can be built by applying basic matrix operations</tt>. The matrix can also be defined when constructed, and it can be reset to the identity matrix (the default) using the <a href="QTransform.html#reset()"><tt>reset</tt></a> function.</p>
<p>The <a href="QTransform.html#QTransform()"><tt>QTransform</tt></a> class supports mapping of graphic primitives: A given point, line, polygon, region, or painter path can be mapped to the coordinate system defined by <i>this</i> matrix using the <a href="QTransform.html#map(com.trolltech.qt.gui.QRegion)"><tt>map</tt></a> function. In case of a rectangle, its coordinates can be transformed using the <a href="QTransform.html#mapRect(com.trolltech.qt.core.QRect)"><tt>mapRect</tt></a> function. A rectangle can also be transformed into a <i>polygon</i> (mapped to the coordinate system defined by <i>this</i> matrix), using the <a href="QTransform.html#mapToPolygon(com.trolltech.qt.core.QRect)"><tt>mapToPolygon</tt></a> function.</p>
<p><a href="QTransform.html#QTransform()"><tt>QTransform</tt></a> provides the <a href="QTransform.html#isIdentity()"><tt>isIdentity</tt></a> function which returns true if the matrix is the identity matrix, and the <a href="QTransform.html#isInvertible()"><tt>isInvertible</tt></a> function which returns true if the matrix is non-singular (i.e. AB = BA = I). The inverted() function returns an inverted copy of <i>this</i> matrix if it is invertible (otherwise it returns the identity matrix). In addition, <a href="QTransform.html#QTransform()"><tt>QTransform</tt></a> provides the <a href="QTransform.html#det()"><tt>det</tt></a> function returning the matrix's determinant.</p>
<p>Finally, the <a href="QTransform.html#QTransform()"><tt>QTransform</tt></a> class supports matrix multiplication, and objects of the class can be streamed as well as compared.</p>

<h3>Rendering Graphics</h3>
<p>When rendering graphics, the matrix defines the transformations but the actual transformation is performed by the drawing routines in <a href="QPainter.html"><tt>QPainter</tt></a>.</p>
<p>By default, <a href="QPainter.html"><tt>QPainter</tt></a> operates on the associated device's own coordinate system. The standard coordinate system of a <a href="QPaintDevice.html"><tt>QPaintDevice</tt></a> has its origin located at the top-left position. The <i>x</i> values increase to the right; <i>y</i> values increase downward. For a complete description, see the <a href="%2E%2E/coordsys.html">coordinate system</tt></a> documentation.</p>
<p><a href="QPainter.html"><tt>QPainter</tt></a> has functions to translate, scale, shear and rotate the coordinate system without using a <a href="QTransform.html#QTransform()"><tt>QTransform</tt></a>. For example:</p>
<p><table width="100%" align="center" cellpadding="2" cellspacing="1" border="0">
<tr valign="top" class="odd"><td><img src="%2E%2E/images/qtransform-simpletransformation.png" /></td><td><pre> void SimpleTransformation::paintEvent(QPaintEvent *)
{
QPainter painter(this);
painter.setPen(QPen(Qt::blue, 1, Qt::DashLine));
painter.drawRect(0, 0, 100, 100);
painter.rotate(45);
painter.setFont(QFont("Helvetica", 24));
painter.setPen(QPen(Qt::black, 1));
painter.drawText(20, 10, "QTransform");
}</pre>
</td></tr>
</table></p>
<p>Although these functions are very convenient, it can be more efficient to build a <a href="QTransform.html#QTransform()"><tt>QTransform</tt></a> and call QPainter::setTransform() if you want to perform more than a single transform operation. For example:</p>
<p><table width="100%" align="center" cellpadding="2" cellspacing="1" border="0">
<tr valign="top" class="odd"><td><img src="%2E%2E/images/qtransform-combinedtransformation.png" /></td><td><pre> void CombinedTransformation::paintEvent(QPaintEvent *)
{
QPainter painter(this);
painter.setPen(QPen(Qt::blue, 1, Qt::DashLine));
painter.drawRect(0, 0, 100, 100);
QTransform transform;
transform.translate(50, 50);
transform.rotate(45);
transform.scale(0.5, 1.0);
painter.setTransform(transform);
painter.setFont(QFont("Helvetica", 24));
painter.setPen(QPen(Qt::black, 1));
painter.drawText(20, 10, "QTransform");
}</pre>
</td></tr>
</table></p>

<h3>Basic Matrix Operations</h3>
<p align="center"><img src="%2E%2E/images/qmatrix-representation.png" /></p><p>A <a href="QTransform.html#QTransform()"><tt>QTransform</tt></a> object contains a 3 x 3 matrix. The <tt>dx</tt> and <tt>dy</tt> elements specify horizontal and vertical translation. The <tt>m11</tt> and <tt>m22</tt> elements specify horizontal and vertical scaling. And finally, the <tt>m21</tt> and <tt>m12</tt> elements specify horizontal and vertical <i>shearing</i>.</p>
<p><a href="QTransform.html#QTransform()"><tt>QTransform</tt></a> transforms a point in the plane to another point using the following formulas:</p>
<pre> x' = m11*x + m21*y + dx
y' = m22*y + m12*x + dy</pre>
<p>The point <i>(x, y)</i> is the original point, and <i>(x', y')</i> is the transformed point. <i>(x', y')</i> can be transformed back to <i>(x, y)</i> by performing the same operation on the inverted() matrix.</p>
<p>The various matrix elements can be set when constructing the matrix, or by using the <a href="QTransform.html#setMatrix(double, double, double, double, double, double, double, double, double)"><tt>setMatrix</tt></a> function later on. They also be manipulated using the translate(), rotate(), scale() and shear() convenience functions, The currently set values can be retrieved using the <a href="QTransform.html#m11()"><tt>m11</tt></a>, <a href="QTransform.html#m12()"><tt>m12</tt></a>, <a href="QTransform.html#m21()"><tt>m21</tt></a>, <a href="QTransform.html#m22()"><tt>m22</tt></a>, <a href="QTransform.html#dx()"><tt>dx</tt></a> and <a href="QTransform.html#dy()"><tt>dy</tt></a> functions.</p>
<p>Translation is the simplest transformation. Setting <tt>dx</tt> and <tt>dy</tt> will move the coordinate system <tt>dx</tt> units along the X axis and <tt>dy</tt> units along the Y axis. Scaling can be done by setting <tt>m11</tt> and <tt>m22</tt>. For example, setting <tt>m11</tt> to 2 and <tt>m22</tt> to 1.5 will double the height and increase the width by 50%. The identity matrix has <tt>m11</tt> and <tt>m22</tt> set to 1 (all others are set to 0) mapping a point to itself. Shearing is controlled by <tt>m12</tt> and <tt>m21</tt>. Setting these elements to values different from zero will twist the coordinate system. Rotation is achieved by carefully setting both the shearing factors and the scaling factors.</p>
<p>Here's the combined transformations example using basic matrix operations:</p>
<p><table width="100%" align="center" cellpadding="2" cellspacing="1" border="0">
<tr valign="top" class="odd"><td><img src="%2E%2E/images/qtransform-combinedtransformation2.png" /></td><td><pre> void BasicOperations::paintEvent(QPaintEvent *)
{
double pi = 3.14;
double a = pi/180 * 45.0;
double sina = sin(a);
double cosa = cos(a);
QTransform translationTransform(1, 0, 0, 1, 50.0, 50.0);
QTransform rotationTransform(cosa, sina, -sina, cosa, 0, 0);
QTransform scalingTransform(0.5, 0, 0, 1.0, 0, 0);
QTransform transform;
transform = scalingTransform * rotationTransform * translationTransform;
QPainter painter(this);
painter.setPen(QPen(Qt::blue, 1, Qt::DashLine));
painter.drawRect(0, 0, 100, 100);
painter.setTransform(transform);
painter.setFont(QFont("Helvetica", 24));
painter.setPen(QPen(Qt::black, 1));
painter.drawText(20, 10, "QTransform");
}</pre>
