This is an experiment. Would it make sense to make an image manipulation language? How about sql? What if you stored an image in a SQL database and manipulated it using standard SQL? Would this work?

This repo loads an image into a simple database.

CREATE TABLE imagedata ( imageid int(11) NOT NULL, x int(11) NOT NULL, y int(11) NOT NULL, r int(11) NOT NULL, g int(11) NOT NULL, b int(11) NOT NULL, a int(11) NOT NULL, PRIMARY KEY (imageid,x,y) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

You can store an image into the database by running

Usage: thelaboflieven.LoadIntoDatabase

Using this command you can store the image into the database.

Usage: thelaboflieven.StoreFromDatabase

Using this command you can retrieve the image from the database.

You can manipulate the image by using SQL queries:

-- greyscale of the image by taking the least value. INSERT INTO imagedata(imageid, x, y, r, g, b, a) SELECT 4 as imageid, x, y, least(r,g,b) as r, least(r,g,b) as g, least(r,g,b) as b , least(r,g,b) as a from imagedata where imageid=3;

-- greyscale of the image by taking the greatest value. INSERT INTO imagedata(imageid, x, y, r, g, b, a) SELECT 4 as imageid, x, y, greatest(r,g,b) as r, greatest(r,g,b) as g, greatest(r,g,b) as b , greatest(r,g,b) as a from imagedata where imageid=3;

-- increase brightness INSERT INTO imagedata(imageid, x, y, r, g, b, a) SELECT 4 as imageid, x, y, least(r+50,255) as r, least(g+50,255) as g, least(b+50,255) as b , least(a+50,255) as a from imagedata where imageid=3;

-- increase brightness INSERT INTO imagedata(imageid, x, y, r, g, b, a) SELECT 4 as imageid, x, y, least(r+50,255) as r, least(g+50,255) as g, least(b+50,255) as b , least(a+50,255) as a from imagedata where imageid=3;
