How to draw to buffer with transparent background GDI+?

Question

Delphi

Hello everybody.
Can GDIP draw to a buffer without a background? So that the output is a matrix of pixels of only those that I have drawn.
I need this so that I can apply any algorithms to the rendered fragment (blur for example).
Thanks in advance

You can use a 32 bit bitmap as a buffer and draw any fragments without a background on it.
A 32-bit bitmap is like uncompressed png.
Here is an example. I draw icons and text on GlassFrame.
