end
 
function love.draw()
    love.graphics.draw(image)
end
 
function love.keypressed(key)
    -- If the image is compressed, it will return CompressedData which doesn't have a mapPixel method.
    -- Currently only dds files can become compressed images.
    if key == "e" and not image:isCompressed() then
        local data = image:getData()
        data:mapPixel(function(x, y, r, g, b, a) return r/2, g/2, b/2, a/2 end)
        image:refresh()
    end
