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.. Select rvalue(1,2,loadimage(blobfield))
From table Order by datetime
Rvalue= red value of x1 and y2 What's the faster or at least, how to use less cpu and memory I didn't search about images udf functions for mysql Any help is wellcome and ideas too :) Well i will use others sum, max, min functions too I don't want to read all images at client side, i want that server do this job I don't know the image size (it can be any pratical size, max near to 16mega pixels), image format could be png, jpg, or another one but i can use client side to rewrite image file to right format I'm considering implement some imagemagick functions inside mariadb, what you think? Thanks guys
