A Question regarding Graphics Filter Driver

NTDEV
1

Hi All,

Currently I am working on a project to manipulate Video Data before it gets displayed on screen for any Graphics Adapter.

To achieve this I intend to develop an Upper Filter Driver for the Display Class.

My question is in order to achieve my objective “Whether writing an Upper Filter driver is enough or I need to also write my display driver.”

I would like somebody to comment on my Driver Stack for the above objective.

GDI

My Upper Filter
|
Display Driver
|
Video Port
|
Video Miniport driver
|
Graphics Card

Thank you for your help.

Any coments would be appreciated.

Note that you will not be able to filter DirectDraw work.
