LÖVE Image Transformations

[TechnoCat]

This library attempts to add some simple photo-manipulation functions into LÖVE.
It includes: black and white, saturation, brightness, color shift, and invert.


I am unsure if my saturation function is correct, it appears to have a similar result to other saturation functions out there.

Code: Select all

r, g, b ,a = imageData:getPixel(i, j)
			avg = (r+g+b)/3
			r = math.max(0, math.min(255, avg+(r-126)*saturation))
			g = math.max(0, math.min(255, avg+(g-126)*saturation))
			b = math.max(0, math.min(255, avg+(b-126)*saturation))

You are reading my mind!
I'm working on a megaman game and I was wondering if we could change the color of megaman without having to create a new image!

To change the color, you should also look at color modulation. love.graphics.setColor(r, g, b, a)

I think I have all what I need, I have to check the color of the pixel and if it is the right blue, I change it to the desired color.

No longer all crashy. Also pads images for odd graphics chipsets.

Nice.
