Hi guys, i will implement a gis system, but my problem isn't gis, my problem is raster (bitmap) images I will save images at mariadb using longblobs And i will create a table with, datetime and image I will need read each r,g,b value from each pixel, example..
i sort of hate to say this on this list, but ... have you checked the new raster data features of PostGIS 2.0? I'm not sure whether they provide exactly what you are looking for, but from the little i heard about this new PostGIS feature i think it may be more suitable for your task, or at least worth a closer look ... -- hartmut
