i'm working on game in java , trying create background without using image files. image consists of square split 4 triangles, each of different color. if point me towards of using graphics2d , saving bufferedimage , great. i recommend: first create bufferedimage using constructor takes 3 ints: width, height, , bufferedimage type, bufferedimage.type_int_argb work well, , width , height constants in program. you extract graphics2d object out of bufferedimage calling creategraphics() method. then draw graphics object using drawxxx(...) methods of have many select from. to change color, call setcolor(color c) on graphics/graphics2d object. when done drawing, sure dispose of graphics object via dispose() method. edit per adrian blackburn, check out bufferedimage tutorial part of standard oracle java tutorials.
