DrawSetTextureRGBA

void ISurface::DrawSetTextureRGBA(int id, const unsigned char *rgba,
int wide, int tall, int hardwareFilter, bool forceReload)

This is a function that you should use to draw raw RGBA data to the HUD, for example when you are rendering a mask.

Sample

Initialization

unsigned char abPic[128 * 256 * 4];

• 128 is height
• 256 is width
• 4 is RGBA

Raw Data

for (j = 0; j < 128; j++) // up/down traverse
{ 
	for (i = 0; i < 256; i++) // left/right traverse
	{
		int offset = (j * 256 + i) * 4;
		char *dst = ((char*)abPic) + offset;
					
		dst[0] = (unsigned char)255;//red
		dst[1] = (unsigned char)255;//green
		dst[2] = (unsigned char)255;//blue
		dst[3] = (unsigned char)255;//alpha
	}
}

Set Up Texture ID

	m_iHudTexture=surface()->CreateNewTextureID();
	surface()->DrawSetTextureRGBA(m_iHudTexture,(unsigned char*)abPic,128,256,false,true);
	surface()->DrawSetColor(Color(255,255,255,128));
	surface()->DrawTexturedRect(0,0,GetWide(),GetTall());
