Intel 82865G Chipset Blit scaling method?

[mound]

My question has to do with what kind of scaling the Intel 82865G Graphics Controller will perform when issued the Blt() command with C++ using DirectX 8.1.

Generally referring to this MSDN Article:

http://msdn.microsoft.com/archive/default.asp?url=/archive/en-us/ddraw7/directdraw7/ddover_7ctz.asp

as well as comments in this thread:

http://groups.google.be/groups?hl=n...o.uk%26rnum%3D1

specifically:

-------------------

>>Does DirectDraw support Bilinear filtering of stretch blits?

>>If not, is there a reason?

Well, you mean resampling...?
It seems that it depends on the video cards.... Some do the filtering,
some simply resize the pixels, without softening the result.
--------------------

So, what doesthe 82865Gchipset do?

My application is always running on a machine with the Intel 82865G Graphics Controller, and we are using Blt() with DirectX to transfer a 1000x1000 device independant bitmap image into a 250x250 region on screen, and I need to tell my customer "what is happening to the pixels" - my search began in the code, which pointed me to the DirectX Blt() command, to the referenced links above and finally here. I haven't been able to locate any specifics on an abstraction layer on the Intel site, so I'm hoping somebody here knows.

Thanks!
