An image can be decomposed into the four channels red, green, blue and alpha. Each channel contains the information, how much of each color in each image pixel or the Alpha channel is the size of the transparency.

following image contains a green circle and a gradient from red to blue. Moreover, it is completely opaque. Green is in this picture only in the green circle there. The gradient contains its endpoints pure red and blue, but mixing between the two tones of colors. order to present information that the individual channels contain gray-scale images are used. White is there for the maximum share of a fully opaque color or black and that color is not available or the image at this point is completely transparent. Shades of gray represent values Dacian dar.


to have to make is to be completely transparent green circle, you have to modify the alpha channel so that there is at this point, a black circle.


seen with modified alpha channel the image then follows.
