Tutorial: Sunburst con Gimp

Today, with a simple trick, we will see how to create a simple effect "Sunbirst" with Gimp. All we need is to have Gimp installed.

We begin to create a work surface white and square, I will use 1000x1000 pixel, but any other dimension (provided that the image is square) può andar bene.

Now select the instrument "Rectangular Selection" a first rectangle, measure 50px wide and 1000px height.

With the copy - Paste, glue the rectangle in the same position in which it is located and assign a level.

We can now color the new level of Black, to do this, just go to "Colors" - "Invert".

At this point will duplicate the level ten times and will position the new levels at a distance of 50px each other. In practice, between a black rectangle and the other there will be a white rectangle the same size of those blacks.

To align the rectangles can be placed blacks the guideline zero horizontal. In this way we will have to take care to be accurate only for the vertical pixels.

Now click with the right of any of the levels created and select "Merge Visible Layers".

To create the effect "Sunburst" we will use the tool "Polar Coordinates", below "Filters" - "Distortions" - "Polar Coordinates".

In the dialog box move the amount relating to the depth of the rim zero.

And here is the final result.

Obviously the result may vary depending on the colors, and depending on the requirements can vary the use to which it is.
