[smremde]

does anyone know the managed DX9 equivelent of DX8's D3DCOLORVALUE - im trying to convert an vb app to vb.net. also the functions that go with colouts like D3DXColorLerp ...

Hmmm... I think you can just declare your own struct, as in:

public struct ColorType
{
	public byte b;
	public byte g;
	public byte r;
	public byte a;

	public ColorType(byte r, byte g, byte b)
	{ 
		this.r = r;
		this.g = g;
		this.b = b;
		this.a = 255;
	}
	public ColorType(Color c)
	{ 
		this.r = c.R;
		this.g = c.G;
		this.b = c.B;
		this.a = c.A;
	}
}

 

At least, that's what I used for returns to the LockRectangle call.

 

The SDK might have a default color struct defined, I can't remember offhand.

the soluction i found was to use

System.Drawing.Color

and the

Microsoft.DirectX.Direct3D.ColorOperator

module to manipulate them

 

from the ms dx9 sdk documentation:
