Hey, I just have a quick question. I am currently trying to create a method that "creates" lights. For this I need to set the transparency of what I am currently drawing. I tried using 
getImage().setTransparency(_t_);
But this sets the transparency of the whole Image. What I want is to set the transparency of the shape I am drawingg next, similar to the 
getImage().setColor(_color_);
method. Is there a way to do this? Or atleast a way to get around this? Thanks for helping, Tritos

You will need to zero the alpha of each pixel individually. This can be done by using the 'setColorAt' method within for loops.
