The following example code illustrate how this is done. The bitmap is tiled around the given origin - the top left of the window is the default - and clipped to the given shape. The second bitmapped brush example shows the effect of moving the origin. </p> <section><title>Using a bitmap patterned brush, with the default origin</title> <ol id="GUID-0F5408B2-5F0C-5810-90F0-AF53F435A809"><li id="GUID-60F09B34-5E46-5CEB-BB18-836D144AAF9A"><p>Load the bitmap file in the standard way. </p> </li> <li id="GUID-6516A6C9-161E-5E15-8F27-624E95BFF78C"><p>Use the bitmap as the graphics context’s brush pattern. </p> </li> <li id="GUID-F2AF6104-7D12-5120-AB35-267AFB4DB80E"><p>Set the brush style to <codeph>TBrushStyle::EPatternedBrush</codeph>. </p> </li> <li id="GUID-290DBDCC-8159-54F4-9587-BEA4B9EBEF9B"><p>Discard the brush pattern using <codeph>DiscardBrushPattern()</codeph>. </p> </li> <li id="GUID-23CD56E3-603E-5415-A7CE-93218B7AF9FC"><p>Destroy the bitmap. </p> </li> </ol> <p>With no brush origin set, the tiling pattern starts at the top left corner of the window. </p> <codeblock id="GUID-B2A5D6F1-A22C-5015-945E-AFBADB2D607E" xml:space="preserve">CFbsBitmap* bitmap = new (ELeave) CFbsBitmap();
