Alpha Zone just won't be Alpha

Hi Everyone, I found a targa loader that works great and implemented it in my code.

But for some reason, the alpha region of my texture , just won't be alpha when I load the Texture in my code.

If I make a texture that is a full purple colored rectangle, and carve out the central part with an alpha zone, in-game the quad is all full purple, instead of having the central part being transparent.

I tried the following code too, and it doesn't work, I don't understand
//NPC
glEnable(GL_BLEND); // Enable Blending

NPC00->Draw();

glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); // Set The Blending To A Nice 50/50 Mode
glDisable(GL_BLEND); // Disable Blending


Draw Function, basically draws a Quad and applies the texture to it.


Can anybody help me understand whats missing I'm just trying to get textures with alpha to work, I usually work with targas, so thats why I got a targa loader.

Thanks.
Should you be setting the blend mode before you draw the quad? You're doing it after.

Though that probably should be done once at initialization and not every time you draw (unless you are frequently changing it).
