Before you begin you need two images with the same height and an idea of what the blending area should be in both images. Then you can start with the following procedure:
Left Part | Right Part | ||
---|---|---|---|
Select the blending area from the left image, copy it and paste it as a new image. | Select a blending area of the same size from the right image, copy it and paste it as a new image. | ||
Create a new image of the same size as the blending area and fill it with a linear gradient which is white on the left edge and black on the right edge. | Make the colors of the gradient for the left part negative to get the gradient for the right part. | ||
Multiply the blending area from the left image with the gradient for the left part using devisor 255. | Multiply the blending area from the right image with the gradient for the right part using devisor 255. | ||
Add the two results of the multiplications using devisor 1. | |||
Copy the result and paste it into one of the selections which are still active in the original images. | |||
Then create a new image with the width of both images minus the width of the blending area and paste the unaltered original image into it. Then copy the altered original image and paste it partially over the just pasted image so the two images blend seamless into each other. | |||
The same technique can be used for vertical blending, creating seamless patterns and looping images horizontally or vertically.
