THE ALGORITHM CONVERTION 2DRE QUADTREE TO RASTER
2DRE四叉树—栅格结构的变换算法

This paper advances and analyses an algorithm converting 2DRE quadtree to. raster. The algorithm can be served as the inverse operation of raster to 2DRE quadtree, but it is not direct inversion, instead, it takes other simpler measur i.e. intersection of 2DRE quadtree and code transforming method in Raster to Quadtree conversion, to make the algorithm more effective. It can also avoid possible trouble of memory overflow caused by the operation on bigger images in smaller memory.
