WebTo access the pixel content from C++/CX, you can query PixelBuffer for the IBufferByteAccess interface, which is a COM interface. Include robuffer.h. You can then call the the IBufferByteAccess::Buffer method to retrieve a pointer to the buffer of bytes that represents the pixel content. This is shown in the C++/CX code example. Applies to WebThen you can write the colour information into the bitmap's data. Note this is a bottom-up DIB; memory earlier in the buffer represents scanlines lower in the image. Another way of putting it is that the the first element of the bitdata relates to the bottom-left. Colour components are in BGR order.
