<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>Drawing Primitives. </p>
<p><a class="el" href="classGdk_1_1Drawable.html" title="Drawing Primitives.">Gdk::Drawable</a> is the base class for all of the objects that accept drawing commands. The available drawables include pixmaps, windows, and bitmaps. <a class="el" href="classGdk_1_1Drawable.html" title="Drawing Primitives.">Drawable</a> is abstract as there is no such type on the server side.</p>
<p>To use a drawable, create a concrete <a class="el" href="classGdk_1_1Drawable.html" title="Drawing Primitives.">Drawable</a> of the type you wish to use and a <a class="el" href="classGdk_1_1GC.html" title="All drawing operations in GDK take a graphics context (GC) argument.">Gdk::GC</a> (graphics context) for that <a class="el" href="classGdk_1_1Drawable.html" title="Drawing Primitives.">Drawable</a>. With the <a class="el" href="classGdk_1_1GC.html" title="All drawing operations in GDK take a graphics context (GC) argument.">GC</a> you can draw lines, text, arcs and such.</p>
<p>An alternative is to create a Cairo::Context with get_cairo_context() while you handle the 'exposed' event of the drawable. For more about this, please see "Using cairo with GTK+" in the "Common questions" section of the GTK+ Reference Manual. </p>

The format of a <a class="el" href="classGdk_1_1Image.html" title="This represents an area for drawing graphics.">Gdk::Image</a> depends on the <a class="el" href="classGdk_1_1Visual.html" title="A Gdk::Visual describes a particular video hardware display format.">Gdk::Visual</a> of the current display, which makes manipulating <a class="el" href="classGdk_1_1Image.html" title="This represents an area for drawing graphics.">Gdk::Image</a> extremely difficult; therefore, in most cases you should use the <a class="el" href="classGdk_1_1Pixbuf.html#a519fae58f951e669b3693a624661e076">Gdk::Pixbuf::create()</a> method that takes a <a class="el" href="classGdk_1_1Drawable.html" title="Drawing Primitives.">Gdk::Drawable</a>, instead of this lower-level function. A <a class="el" href="classGdk_1_1Pixbuf.html">Gdk::Pixbuf</a> contains image data in a canonicalized RGB format, rather than a display-dependent format. Of course, there's a convenience vs. speed tradeoff here, so you'll want to think about what makes sense for your application.</p>
<p><em>x</em>, <em>y</em>, <em>width</em>, and <em>height</em> define the region of <em>drawable</em> to obtain as an image.</p>
<p>You would usually copy image data to the client side if you intend to examine the values of individual pixels, for example to darken an image or add a red tint. It would be prohibitively slow to make a round-trip request to the windowing system for each pixel, so instead you get all of them at once, modify them, then copy them all back at once.</p>
<p>If the X server or other windowing system backend is on the local machine, this function may use shared memory to avoid copying the image data.</p>
<p>If the source drawable is a <a class="el" href="classGdk_1_1Window.html" title="A Gdk::Window is a rectangular region on the screen.">Gdk::Window</a> and partially offscreen or obscured, then the obscured portions of the returned image will contain undefined data. </p>
