Channel alpha
The images can have a fourth channel, the channel alpha , in addition to the three channels Rouge, Vert and Blue. This channel does not modify the colors of the image and is used in the majority of the cases to manage the Transparence image for example to make it possible to see what there is behind the image (example of image: ). For example the formats GIF and png can support a channel alpha. In the video games, the use of the channel alpha on the textures makes it possible for example to modify their reflection or their transparency.
