<P>
<p>The <a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> class provides a hardware-independent image representation that allows direct access to the pixel data, and can be used as a paint device.</p>
<p>Qt provides four classes for handling image data: <a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a>, <a href="QPixmap.html"><tt>QPixmap</tt></a>, <a href="QBitmap.html"><tt>QBitmap</tt></a> and <a href="QPicture.html"><tt>QPicture</tt></a>. <a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> is designed and optimized for I/O, and for direct pixel access and manipulation, while <a href="QPixmap.html"><tt>QPixmap</tt></a> is designed and optimized for showing images on screen. <a href="QBitmap.html"><tt>QBitmap</tt></a> is only a convenience class that inherits <a href="QPixmap.html"><tt>QPixmap</tt></a>, ensuring a depth of 1. Finally, the <a href="QPicture.html"><tt>QPicture</tt></a> class is a paint device that records and replays <a href="QPainter.html"><tt>QPainter</tt></a> commands.</p>
<p>Because <a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> is a <a href="QPaintDevice.html"><tt>QPaintDevice</tt></a> subclass, <a href="QPainter.html"><tt>QPainter</tt></a> can be used to draw directly onto images. When using <a href="QPainter.html"><tt>QPainter</tt></a> on a <a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a>, the painting can be performed in another thread than the current GUI thread, that is except rendering text (because <a href="QFont.html"><tt>QFont</tt></a> is GUI dependent). To render text in another thread, the text must first be derived as a <a href="QPainterPath.html"><tt>QPainterPath</tt></a> in the GUI thread.</p>
<p>The <a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> class supports several image formats described by the <a href="QImage.html#Format-enum">Format</tt></a> enum. These include monochrome, 8-bit, 32-bit and alpha-blended images which are available in all versions of Qt 4.x. In addition, <a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> supports several formats that are specific to Qtopia Core</tt>.</p>
<p><a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> provides a collection of functions that can be used to obtain a variety of information about the image. There are also several functions that enables transformation of the image.</p>
<p><a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> objects can be passed around by value since the <a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> class uses implicit data sharing</tt>. <a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> objects can also be streamed and compared.</p>

<h3>Reading and Writing Image Files</h3>
<p><a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> provides several ways of loading an image file: The file can be loaded when constructing the <a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> object, or by using the load() or loadFromData() functions later on. <a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> also provides the static fromData() function, constructing a <a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> from the given data. When loading an image, the file name can either refer to an actual file on disk or to one of the application's embedded resources. See <a href="%2E%2E/resources.html">The Qt Resource System</tt></a> overview for details on how to embed images and other resource files in the application's executable.</p>
<p>Simply call the save() function to save a <a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> object.</p>
<p>The complete list of supported file formats are available through the QImageReader::supportedImageFormats() and QImageWriter::supportedImageFormats() functions. New file formats can be added as plugins. By default, Qt supports the following formats:</p>

<a name="pixel-manipulation"></a>
<h3>Pixel Manipulation</h3>
<p>The functions used to manipulate an image's pixels depend on the image format. The reason is that monochrome and 8-bit images are index-based and use a color lookup table, while 32-bit images store ARGB values directly. For more information on image formats, see the <a href="QImage.html#image-formats">Image Formats</tt></a> section.</p>
<p>In case of a 32-bit image, the <a href="QImage.html#setPixel(int, int, int)"><tt>setPixel</tt></a> function can be used to alter the color of the pixel at the given coordinates to any other color specified as an ARGB quadruplet. To make a suitable QRgb value, use the qRgb() (adding a default alpha component to the given RGB values, i.e. creating an opaque color) or qRgba() function. For example:</p>
<p><table align="center" cellpadding="2" cellspacing="1" border="0">
<tr valign="top" class="odd"><td><img src="%2E%2E/images/qimage-32bit_scaled.png" /></td><td><pre> QImage image(3, 3, QImage::Format_RGB32);
QRgb value;
value = qRgb(189, 149, 39); <span class="comment">// 0xffbd9527</span>
image.setPixel(1, 1, value);
value = qRgb(122, 163, 39); <span class="comment">// 0xff7aa327</span>
image.setPixel(0, 1, value);
image.setPixel(1, 0, value);
value = qRgb(237, 187, 51); <span class="comment">// 0xffedba31</span>
image.setPixel(2, 1, value);</pre>
</td></tr>
<thead><tr valign="top" class="qt-style"><th colspan="2">32-bit</th></tr></thead>
</table></p>
<p>In case of a 8-bit and monchrome images , the pixel value is only an index from the image's color table. So the <a href="QImage.html#setPixel(int, int, int)"><tt>setPixel</tt></a> function can only be used to alter the color of the pixel at the given coordinates to a predefined color from the image's color table, i.e. it can only change the pixel's index value. To alter or add a color to an image's color table, use the <a href="QImage.html#setColor(int, int)"><tt>setColor</tt></a> function.</p>
<p>An entry in the color table is an ARGB quadruplet encoded as an QRgb value. Use the qRgb() and qRgba() functions to make a suitable QRgb value for use with the <a href="QImage.html#setColor(int, int)"><tt>setColor</tt></a> function. For example:</p>
<p><table align="center" cellpadding="2" cellspacing="1" border="0">
<tr valign="top" class="odd"><td><img src="%2E%2E/images/qimage-8bit_scaled.png" /></td><td><pre> QImage image(3, 3, QImage::Format_Indexed8);
QRgb value;
value = qRgb(122, 163, 39); <span class="comment">// 0xff7aa327</span>
image.setColor(0, value);
value = qRgb(237, 187, 51); <span class="comment">// 0xffedba31</span>
image.setColor(1, value);
value = qRgb(189, 149, 39); <span class="comment">// 0xffbd9527</span>
image.setColor(2, value);
image.setPixel(0, 1, 0);
image.setPixel(1, 0, 0);
image.setPixel(1, 1, 2);
image.setPixel(2, 1, 1);</pre>
</td></tr>
<thead><tr valign="top" class="qt-style"><th colspan="2">8-bit</th></tr></thead>
</table></p>
<p><a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> also provide the <a href="QImage.html#scanLine(int)"><tt>scanLine</tt></a> function which returns a pointer to the pixel data at the scanline with the given index, and the <a href="QImage.html#bits()"><tt>bits</tt></a> function which returns a pointer to the first pixel data (this is equivalent to <tt>scanLine(0)</tt>).</p>
<a name="image-formats"></a>
<h3>Image Formats</h3>
<p>Each pixel stored in a <a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> is represented by an integer. The size of the integer varies depending on the format. <a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> supports several image formats described by the <a href="QImage.html#Format-enum">Format</tt></a> enum. The monochrome (1-bit), 8-bit and 32-bit images are available in all versions of Qt. In addition Qtopia Core also supports 2-bit, 4-bit, and 16-bit images. For more information about the Qtopia specific formats, see the documentation of the <a href="QImage.html#Format-enum">Format</tt></a> enum.</p>
<p>Monochrome images are stored using 1-bit indexes into a color table with at most two colors. There are two different types of monochrome images: big endian (MSB first) or little endian (LSB first) bit order.</p>
<p>8-bit images are stored using 8-bit indexes into a color table, i.e. they have a single byte per pixel. The color table is a QVector<QRgb>, and the QRgb typedef is equivalent to an unsigned int containing an ARGB quadruplet on the format 0xAARRGGBB.</p>
<p>32-bit images have no color table; instead, each pixel contains an QRgb value. There are three different types of 32-bit images storing RGB (i.e. 0xffRRGGBB), ARGB and premultiplied ARGB values respectively. In the premultiplied format the red, green, and blue channels are multiplied by the alpha component divided by 255.</p>
<p>An image's format can be retrieved using the <a href="QImage.html#format()"><tt>format</tt></a> function. Use the <a href="QImage.html#convertToFormat(com.trolltech.qt.gui.QImage.Format, com.trolltech.qt.core.Qt.ImageConversionFlags)"><tt>convertToFormat</tt></a> functions to convert an image into another format. The <a href="QImage.html#allGray()"><tt>allGray</tt></a> and <a href="QImage.html#isGrayscale()"><tt>isGrayscale</tt></a> functions tell whether a color image can safely be converted to a grayscale image.</p>
<a name="image-transformations"></a>
<h3>Image Transformations</h3>
<p><a href="QImage.html#QImage(com.trolltech.qt.core.QSize, com.trolltech.qt.gui.QImage.Format)"><tt>QImage</tt></a> supports a number of functions for creating a new image that is a transformed version of the original: The <a href="QImage.html#createAlphaMask(com.trolltech.qt.core.Qt.ImageConversionFlags)"><tt>createAlphaMask</tt></a> function builds and returns a 1-bpp mask from the alpha buffer in this image, and the <a href="QImage.html#createHeuristicMask(boolean)"><tt>createHeuristicMask</tt></a> function creates and returns a 1-bpp heuristic mask for this image. The latter function works by selecting a color from one of the corners, then chipping away pixels of that color starting at all the edges.</p>
<p>The <a href="QImage.html#mirrored(boolean, boolean)"><tt>mirrored</tt></a> function returns a mirror of the image in the desired direction, the <a href="QImage.html#scaled(com.trolltech.qt.core.QSize, com.trolltech.qt.core.Qt.AspectRatioMode, com.trolltech.qt.core.Qt.TransformationMode)"><tt>scaled</tt></a> returns a copy of the image scaled to a rectangle of the desired measures, the <a href="QImage.html#rgbSwapped()"><tt>rgbSwapped</tt></a> function constructs a BGR image from a RGB image, and the <a href="QImage.html#alphaChannel()"><tt>alphaChannel</tt></a> function constructs an image from this image's alpha channel.</p>
<p>The <a href="QImage.html#scaledToWidth(int, com.trolltech.qt.core.Qt.TransformationMode)"><tt>scaledToWidth</tt></a> and <a href="QImage.html#scaledToHeight(int, com.trolltech.qt.core.Qt.TransformationMode)"><tt>scaledToHeight</tt></a> functions return scaled copies of the image.</p>
<p>The <a href="QImage.html#transformed(com.trolltech.qt.gui.QTransform, com.trolltech.qt.core.Qt.TransformationMode)"><tt>transformed</tt></a> function returns a copy of the image that is transformed with the given transformation matrix and transformation mode: Internally, the transformation matrix is adjusted to compensate for unwanted translation, i.e. <a href="QImage.html#transformed(com.trolltech.qt.gui.QTransform, com.trolltech.qt.core.Qt.TransformationMode)"><tt>transformed</tt></a> returns the smallest image containing all transformed points of the original image. The static <a href="QImage.html#trueMatrix(com.trolltech.qt.gui.QTransform, int, int)"><tt>trueMatrix</tt></a> function returns the actual matrix used for transforming the image.</p>
<p>There are also functions for changing attributes of an image in-place:</p>

<tt>data</tt>. The <tt>width</tt> and <tt>height</tt> must be

If the image is in an indexed color format, set the color table
for the image using setColorTable().
<p>
Unlike the similar QImage constructor that takes a non-const data
buffer, this version will never alter the contents of the buffer. For
example, calling QImage::bits() will return a deep copy of the image,
rather than the buffer passed to the constructor. This allows for the
efficiency of constructing a QImage from raw data, without the
possibility of the raw data being changed.
