In my app I am using a bitmap of the earth as background for my
visualization. I found that the resample() method of FlatField is a
great method of zooming in and out of bitmaps without getting this big
rastered pixeldata because resample internally smoothes the bitmap. So
you can prevent your resolution while zooming your display. This is a
bit slower than a vector based solution but looks really beautiful.
