v63 v64 38 38 * Storage in '''tiles''' instead of by row 39 39 * Reasoning: Glynn said on the mailing list: "In most cases, single-level tiled storage will give you close to the same performance with a lot less complexity." 40 * The G3d library already implements a tile based approach with tile caching and tile file buffer for arbitrary read and write access 40 * The G3d library already implements a tile based approach with tile caching and tile file buffer for arbitrary read and write access 41 41 * Function needed to check whether tiles are all null, or all the same value. 42 42 * What tile size should be used? Could be user/program specified, or standard value of something like 64x64. If there isn't a fixed value then there should be utility program that can convert tiled rasters to different tile sizes.
