Create Background With Polka Dot Pattern in GIMP 2.8
In this tutorial I want to show you how to create a simple pattern in GIMP. As an example I decided to take Polka Dot pattern which can be met everywhere: on cloths, on the kitchen utensils, as a background etc.
If you don’t have GIMP yet, download it from here: GIMP
Open GIMP and make a new file by going to File / New / 100 x 100px
Make a new Transparent Layer by going to Layer / New / Transparency
Create Guides by going to Image / Guides / New Guide (by Present) / Horizontal / 50%
Now repeat step, but change Horizontal to Vertical. You should have image with two lines going across like in Fig 1.
Activate “Snap to Guide” by going to View / Snap to Guides and tick it.
Activate “Snap to Canvas Edges” by going to View / Snap to Canvas Edges and tick it.
Activating “Snaps” will help us with placement of the dots.
Select a 100% Hardness brush and set size to 30px.
Set your foreground colour to White, make the background layer invisible by clicking on the eye icon next to it and place 4 dots like shown in Fig 2. When making dots, you should feel how your brash is slightly magnetised to the guides and to the edges of the canvas.
Save your pattern by going to File / Export (note I’m using GIMP 2.8) / Username / GIMP 2.8 / Patterns.Create a pattern name of your choice and going to “Select file type (by extension)” click on GIMP pattern.Now the name of your pattern should finish with .pat
Now go to your Patterns dialog and click Refresh button as shown in Fig 3.If you don’t have your patterns activated, go to Windows / Dockable dialogs / Patterns.
Find your Polka dot pattern and click on it.
Create a new image by going to File / New / 1000 x 1000
Using Bucket Fill add red colour to your image.
With your Bucket tool activated go to Tool Options and switch from FG colour fill to Pattern fill. Make sure Fill whole selection is selected. Now click anywhere on the image, it should now get filled with dots as shown in Fig 4.
Save your background by going to File / Export / Select folder / Give name to your background and select JPG from “Select file type (by extension)”, press Export.
Final note: This pattern is seamless, so if you duplicate background with this pattern and place one next to another, you will get an identical continuous pattern.
