VGA Output from Nios II program

[Altera_Forum]

Does anyone know if there is any VGA screen initializations that need to be done in a project where you want to output a picture to a VGA screen from a Nios II program through an Altera development board? 

 I have a VGA component in SOPC builder that I downloaded off the Altera website.  I have an Altera DE1 development board I am trying to use to put images on a VGA screen.

You can find the HAL drivers included with the core. 

There are the initialization and simple demo.

I'm also trying to use the VGA ouput of a DE2 board. Unfortunately i can't undestand how to set corectly the color of one pixel. 

 I tried to look at altera driver, but i'm there is not any documentation, and when i have a look in the vhdl file, there is not a lot of explanation.
