<h2>Member Function Documentation</h2>

<h3 class="fn"><a name="QBitmap-5"></a>QBitmap::QBitmap ( int <i>w</i>, int <i>h</i>, bool <i>clear</i> )</h3>

<p>Use the <a href="qbitmap.html">QBitmap</a>(<i>w</i>, <i>h</i>) constructor. If <i>clear</i> is true, call <a href="qbitmap.html#clear">clear</a>() afterward.</p>

<p>See also <a href="qbitmap.html#clear">clear</a>().</p>

<h3 class="fn"><a name="QBitmap-6"></a>QBitmap::QBitmap ( const <a href="qsize.html">QSize</a> & <i>size</i>, bool <i>clear</i> )</h3>

<p>Use the <a href="qbitmap.html">QBitmap</a>(<i>size</i>) constructor. If <i>clear</i> is true, call <a href="qbitmap.html#clear">clear</a>() afterward.</p>

<p>See also <a href="qbitmap.html#clear">clear</a>().</p>

<h3 class="fn"><a name="QBitmap-7"></a>QBitmap::QBitmap ( int <i>width</i>, int <i>height</i>, const <a href="qtglobal.html#uchar-typedef">uchar</a> * <i>bits</i>, bool <i>isXbitmap</i> = false )</h3>

<p>Constructs a bitmap with the given <i>width</i> and <i>height</i>, and sets the contents to the <i>bits</i> supplied.</p>

<p>The <i>isXbitmap</i> flag should be true if <i>bits</i> was generated by the <a href="winsystem.html#x11">X11</a> bitmap program. The X bitmap bit order is little endian. The <a href="qimage.html">QImage</a> documentation discusses bit order of monochrome images. Opposed to <a href="qimage.html">QImage</a>, the data has to be byte aligned.</p>

<p>Example (creates an arrow bitmap):</p>

<pre>  uchar arrow_bits[] = { 0x3f, 0x1f, 0x0f, 0x1f, 0x3b, 0x71, 0xe0, 0xc0 };

QBitmap bm(8, 8, arrow_bits, true);</pre>

<h3 class="fn"><a name="QBitmap-8"></a>QBitmap::QBitmap ( const <a href="qimage.html">QImage</a> & <i>image</i> )</h3>

<p>Constructs a bitmap that is a copy of the <i>image</i> given.</p>

<p>Dithering will be performed if the image has a <a href="qimage.html#depth">QImage::depth</a>() greater than 1.</p>

<h3 class="fn"><a name="QBitmap-10"></a>QBitmap::QBitmap ( const <a href="qsize.html">QSize</a> & <i>size</i>, const <a href="qtglobal.html#uchar-typedef">uchar</a> * <i>bits</i>, bool <i>isXbitmap</i> = false )</h3>

<p>Constructs a bitmap with the given <i>size</i>, and sets the contents to the <i>bits</i> supplied.</p>

<h3 class="fn"><a name="xForm"></a>QBitmap QBitmap::xForm ( const <a href="qmatrix.html">QMatrix</a> & <i>matrix</i> ) const</h3>

<p>Use transform(<i>matrix</i>) instead.</p>

<h3 class="fn"><a name="operator-eq-2"></a>QBitmap & QBitmap::operator= ( const <a href="qimage.html">QImage</a> & <i>image</i> )</h3>

<p>This is an overloaded member function, provided for convenience. It behaves essentially like the above function.</p>

<p>Converts the image <i>image</i> to a bitmap, and assigns the result to this bitmap. Returns a reference to the bitmap.</p>

<p>Dithering will be performed if the image has a <a href="qimage.html#depth">QImage::depth</a>() greater than 1.</p>
