Well, it is not possible directly. But you can copy the image into other HBITMAPs which can be displayed in other windows on your computer.

The method "getPtr" of the membuffer (http://www.imagingcontrol.com/en_US/support/documentation/class/IFrame.htm) returns a pointer to the pixels.
The method "getBitmapInfoHeader" of the membuffer (http://www.imagingcontrol.com/en_US/support/documentation/class/meth_descMemBuffer_getBitmapInfoHeader.htm) return the BITMAPINFOHEADER of the membuffer, which contains information you need to copy a bitmap. I also suggest to have a look into the "childview.cpp" of the "demoapp" sample. In there you will find the use of "StretchDIBits()" (or similar), that shows, how to copy a membuffer using Device Contexts (DC). This is GDI programming.
