transparency ALPHA & ofAndroid

hei!

today I was looking at this: http://wiki.openframeworks.cc/index.php?title=OpenGL-in-openFrameworks

I wanted to show some image with transparency (png) and then set a dynamic alpha (basically I was wondering if I could do some transitions with alpha for my menus).

But this code doesn’t work as the images show.

  
void testApp::draw(){  
  
        // enable blending  
	glEnable(GL_BLEND);  
  
	// set blend mode  
	glBlendFunc(GL_SRC_ALPHA,GL_ONE);  
  
	// set to 50% alpha  
	glColor4f(1.0f,1.0f,1.0f,0.5f);  
  
	// draw the picture  
	myPicture.draw(0, 0);  
  
	// draw the picture again  
	myPicture.draw(53, 40);  
  
        // turn off alpha blending  
	glDisable(GL_BLEND);  
  
}  

It multiplies the image color, tinting it and making it completely white.

Is it because of Android OpenGl??

Have anyone figured out how to work with dynamic alphas in Android?

thks!!

What device? I’ve had alpha issues on Kindle Fire (not in OF though)
