Best way to create an image file

Question

Hi,
I am drawing a huge image by using java 2d .to store that image into a image file i am using the following code...
BufferedImage bf=new BufferedImage(diagramHandle.getWidth(),diagramHandle.getHeight(),BufferedImage.SCALE_SMOOTH);
               Graphics2D gd=bf.createGraphics();
               diagramHandle.paintComponent(gd);--> this class will render the image and store into bufferred image
               ImageIO.write(bf, "PNG", file);
for the small images it is working properly. but when i am trying to generate bigger images more than 1240 width and 40000 height it is throwing out of memory error. with out increasing the heap size is there any way to store the images better way..can i directly use the gd object to draw the image..?
Please help me out

thanks for your reply. if i changed the type also it is throwing the out of memory exception ..
at java.awt.image.DataBufferByte.<init>(Unknown Source)
     at java.awt.image.Raster.createInterleavedRaster(Unknown Source)
     at java.awt.image.BufferedImage.<init>(Unknown Source)

it is throwing the error while constructing the bufferedimage with the specified width and height.is there any other way around to create an image file.please help me out.
