Author Topic: Tint an Image (Read 3748 times)

I am using SFML2 in Visual Studio 2010 (Windows). See this post for more background information.

I was looking through the sf::Image documentation and I didn't see anything about tinting an image. I previously used SDL, in which tinting is very easy. I have a white sprite with alpha that I would like to tint one of three colors then copy it onto another image.

What is the best way to do this in SFML2?

I'm not sure I understand right what you mean by 'tinting an image' - changing RGB values?. You can create an image filled with a specific color. You can change the colors of pixels in an existing image.

Sorry about the confusion.

For example, if I want to tint my white image to RGB(255, 0, 255) (assuming the source image is white, per color theory).

In XNA, there is a tint parameter easily accessible (documentation).

You would display that image using a Sprite in SFML, and Sprites have the SetColor method, which works like a tint. Alpha blending can also be achieved using this.
