Saving a TBitmap to a VTDB

[Cataclysm]

Hi All!

Does anybody have any ideas to save a Bitmap to a VTDB?
I want to do this without using a TAGFImage (because then I'll need an IDirectDevice).

Actually I'm looking for a piece of code like the VTDBTool in which the bitmaps are saved to the VTDB!

Thanx in advance,

Coen

In examples section (for PD3 - it's in "PowerDraw2.x Examples" directory) there is VTDView sample. It only loads bitmaps, so you'll have to figure out how to do it vise-versa (sorry, right now got no time to provide an example)...

Here it is:

procedure BitmapToAGF;
var
LRect: TD3DLocked_Rect;
Res, i: Integer;
DestP: Pointer;
begin
b.PixelFormat := pf32bit; // convert bitmap format to 32-bit

a.Finalize;
Res := a.Initialize(TexWidth, TexHeight, PtCount, PtWidth, PtHeight, D3DFMT_A4R4G4B4);
if (Res <> errNone) then Exit;

Res := a.Lock(0, LRect);
if (Res <> errNone) then Exit;

for i := 0 to a.TextureHeight - 1 do
begin
DestP := Pointer(Integer(LRect.Bits) + (LRect.Pitch * i));
try
pdrawLineConv(b.Scanline[i], DestP, a.TextureWidth, D3DFMT_A8R8G8B8, D3DFMT_A4R4G4B4);
except
end;
end;

Res := a.Unlock(0);
if (Res <> errNone) then Exit;

a.TransparentColor := Color;
end;

I tried that, and it looks alright. I think it will work in Powerdraw 3, but the PDrawEx.Dll in PowerDraw 2.42 doesn't seem to have pdrawLineConv... Any suggestions how to get the code working in Powerdraw 2.42?

Thanx in advance!

It does only work in v3 I think. I never used any previous versions of PowerDraw.

Ok! That's what I thought... no problem, we'll just have to wait doing that until version 3 goes final

Thanx for your help!
