draw2DImage versus addImage

[asphodeli]

Hi all, I've noticed that there are two ways to draw an image on-screen - one is to use the video driver's draw2DImage, and the other is the IGUIEnvironment's addImage. I suppose draw2DImage will consume less memory? Also, does the fader work on draw2DImage images?

I'm going to take a very quick guess and say that draw2Dimage draws an image but addImage creates a widget that draws an image. I'm not entirely sure, but that's definitely what the names suggest.

This is true.

well, okay, but i'm just wondering if the fader works for draw2DImage, i.e. the fader will "cover up" the draw2DImage

Sounds like it should be easy enough to test, but looking at the source code it seems that it should. Why don't you give it a try?

there is SColor parameter in draw2DImage. just set and decrease the alpha value.

Have done it, fader does not change the alpha values. Ah well, I could always custom-class a IGUIElement.
