<hr><a name="_details"></a><h2>Detailed Description</h2>
This is a windows DIBSection wrapped in a PLBmp-derived class. It can be used just like a <a class="el" href="classPLWinBmp.html">PLWinBmp</a> can be used. In addition, PLDIBSection can give access to the bitmap as a GDI bitmap handle. This bitmap handle can be selected into a device context. All normal GDI drawing functions can be used to write on the bitmap in this way.<p>
Internally, PLDIBSections are stored with header and bits in two separate buffers.

Calling this function causes the windows DIBSection to be detached from the PLDIBSection object. The bitmap data are not deleted in this function. This means that the bitmap handle and the bitmap memory (bits and BMI) must be deleted by some other object. The PLDIBSection object is in the same state as after a constructor call after this function is called. </td>

Returns a GDI handle to the bitmap. This handle can be selected into a DC and used in normal GDI operations. Under Windows NT, GDI operations can be queued.
