Hello my dear friends,
in this post I will show you how to overlay one image over another image like if you would print an image over wood.
In this example we need two images, one is a wood image and another one is just a photo or whatever image do you like.
To make such effect we will do a few simple steps, here you are:
- create an empty image that will be a result image;
- draw your wood texture over that empty image;
- combine colors of the wood image and a photo, using the following formula c1 * c2 / 255.0;
The main thing here is to multiply each component of colors and divide it by 255.0. You do not need to do anything with alpha,
here is the short code:
for (int y = 0; y < surfWood.Bounds.Height; y++)
for (int x = 0; x < surfWood.Bounds.Width; x++)
color = surfWood.GetPixel(x, y);
color2 = surfSrc.GetPixel(x, y);
, x, y);
the result you will get is like the following:
so looks like you have printed out on a wood plate.
