<hr><a name="_details"></a><h2>Detailed Description</h2>
A PLSubBmp is a way to manipulate bitmap data in an application-defined memory region or a rectangular subsection of another <a class="el" href="classPLBmp.html">PLBmp</a>. All operations on PLBmps that don't change the size or bpp of the image can be performed on a PLSubBmp. A PLSubBmp can be used as source for all filter operations. It doesn't own the pixel data it manipulates, so care must be taken to ensure that the data remains valid as long as the PLSubBmp exists.
