Here's a quick hack that adds five functions to love that work with colors in the 0-255 range. I'm gonna use them while porting stuff from 0.10.2.
Code: Select all
local function rgba2raw(r, g, b, a)
return
math.floor(r * 255 + .5),
math.floor(g * 255 + .5),
math.floor(b * 255 + .5),
a and math.floor(a * 255 + .5)
end
local function color2raw(r, g, b, a)
if type(r) == 'table' then
r, g, b, a = unpack(r)
end
return rgba2raw(r, g, b, a)
end
local function raw2color(r, g, b, a)
if type(r) == 'table' then
r, g, b, a = unpack(r)
end
return r / 255, g / 255, b / 255, a and a / 255
end
local function mapRaw(fn, x, y, r, g, b, a)
return raw2color(fn(x, y, rgba2raw(r, g, b, a)))
end
local ImageData = debug.getregistry().ImageData
function ImageData:getRawPixel(x, y)
return color2raw(self:getPixel(x, y))
end
function ImageData:setRawPixel(x, y, r, g, b, a)
return self:setPixel(x, y, raw2color(r, g, b, a))
end
function ImageData:mapRawPixel(fn)
return self:mapPixel(function(x, y, r, g, b, a)
return mapRaw(fn, x, y, r, g, b, a)
end)
end
function love.graphics.setRawColor(r, g, b, a)
return love.graphics.setColor(raw2color(r, g, b, a))
end
function love.graphics.rawClear(r, g, b, a, stencil, depth)
r, g, b, a = raw2color(r, g, b, a)
return love.graphics.clear(r, g, b, a, stencil, depth)
end
It's mostly untested though. I probably missed a function or three, and there's always room for improvement. If there is any interest from the community, I'll make a lib and put it on github.
