Message: [QUOTE="iamfractal, post: 567472"] Hi, folks! I have a BufferedImage onto which I'm drawing simple lines and polygons, but I want to allow the user to magnify the final graphic and allow, "Zooming-in," on a choice line or polygon. To cater for this magnification, I'd like the graphic to be placed in a JScrollPane, so that, as the user zooms, the graphic can be dragged about. My problem is that, as I magnify, I must double the size of the BufferedImage each time and draw the lines and polygons twice as big; but after a couple of magnifications, the BufferedImage throws an OutOfMemory exception. Is there a simple way to create allocate memory for only a particaly part of a BufferedImage, rather than for the whole thing? (I want neither to use the Image.getScaledInstance() to zoom-in (because of pixellation), nor to increase heap-size to allow for monster BufferedImages.)
