<p>In other words, copies image data from a server-side drawable to a client-side RGB(A) buffer. This allows you to efficiently read individual pixels on the client side.</p>
<p>This function will create an RGB pixbuf with 8 bits per channel with the same size specified by the <em>width</em> and <em>height</em> arguments. The pixbuf will contain an alpha channel if the <em>window</em> contains one.</p>
<p>If the window is off the screen, then there is no image data in the obscured/offscreen regions to be placed in the pixbuf. The contents of portions of the pixbuf corresponding to the offscreen region are undefined.</p>
<p>If the window you're obtaining data from is partially obscured by other windows, then the contents of the pixbuf areas corresponding to the obscured regions are undefined.</p>
<p>If the window is not mapped (typically because it's iconified/minimized or not on the current workspace), then an invalid object will be returned.</p>

<p>Create a <a class="el" href="classGdk_1_1Pixbuf.html">Gdk::Pixbuf</a> from a flat representation that is suitable for storing as inline data in a program. </p>
<p>This is useful if you want to ship a program with images, but don't want to depend on any external files.</p>
<p>GTK+ ships with a program called <code>gdk-pixbuf-csource</code> which allows for conversion of GdkPixbufs into such a inline representation. In almost all cases, you should pass the <code>–raw</code> flag to <code>gdk-pixbuf-csource</code>. A sample invocation would be:</p>
<p><code>gdk-pixbuf-csource –raw –name=myimage_inline myimage.png</code></p>
<p>For the typical case where the inline pixbuf is read-only static data, you don't need to copy the pixel data unless you intend to write to it, so you can pass <code>false</code> for <em>copy_pixels</em>. (If you pass <code>–rle</code> to <code>gdk-pixbuf-csource</code>, a copy will be made even if <em>copy_pixels</em> is <code>false</code>, so using this option is generally a bad idea.)</p>
<p>If you create a pixbuf from const inline data compiled into your program, it's probably safe to ignore errors, since things will always succeed. For non-const inline data, you could get out of memory. For untrusted inline data located at runtime, you could have corrupt inline data in addition.</p>

ICO images can be saved in depth 16, 24, or 32, by using the "depth" parameter. When the ICO saver is given "x_hot" and "y_hot" parameters, it produces a CUR instead of an ICO.</p>
