This GIMP (GNU) tutorial demonstrates how to Stroke Text with Rainbow Colours.
You can quickly Undo a step at any time by pressing Ctrl then Z. Alternatively, click a previous Undo History snapshot - Windows then Dockable Dialogues then click Undo History. In addition, to Zoom in (or Zoom out) of your image; from the top menu, choose View then select a Zoom Tool from the subsequent drop-down list.
Ensure the Layers and the Undo History Palettes are visible, and then drag them into position over your workspace - (Windows then Dockable Dialogues - then click Layers and Undo History).
Launch GIMP & Organise Its Workspace & Palettes
Stroke With Solid Colour; Add A Bevel & A Perspective Shadow
Create a New Image, and set the following Width and Height and Fill with Transparency attributes. Alternatively, select Width and Height dimensions of your choice.
If you are not printing your work, set a Resolution of 72.000 Pixels. If you are printing your work, a resolution of 300.000 Pixels will be better.
Now, from the left-side Toolbox, activate the Text Tool. (Text Tool Tutorial).
The size of the Text is determined by your Image’s Resolution (Size) - and the look you are seeking.
Set the Foreground Colour Swatch to the colour you would like your text to be -
I am selecting Solid Black. (I am also utilising a Font named Fairydust).
After you have set your Text attributes: left-click once over the White Image. And from the subsequent Gimp Text Editor dialogue box, type in a Text String of your choice, and then click Close - as illustrated below.
From the left-side Toolbox, activate the Move Tool.
Then left-click over your workspace’s Text; (and remembering to leave room for the subsequent Rainbow Stroke), drag your Text to a central position - as illustrated below.
Now, right-click the Text Layer - and from the subsequent drop-down list click Alpha to Selection.
Your text will now be isolated by the following Selection Marquee.
Now, create a New Transparent Layer by clicking the following Create a new layer tab - and name it something like Stroke. And then drag the New Layer below the Text Layer - as illustrated below.
Ensuring the Stroke Layer remains active. From the top menu, choose Select and then choose Grow. And from the subsequent Grow dialogue box, select a Grow Selection setting of your choice, (this will be the Rainbow Stroke’s Width), and then click OK.
I have selected a Grow selection by (Stroke Width) of 10 Pixels.
Then from the left-side Toolbox, activate the Blend Tool.
And choose a Rainbow Colour of your choice from the subsequent Options Box.
For personal results, experiment with different Gradients and Gradient Shapes.
Now, press down the Ctrl Key, and simultaneously left-click and stretch a Gradient Line across your Selected Text. As soon as you release the mouse button, a Gradient will be applied to your selected border - as illustrated below.
It’s important to experiment with the Gradient Line’s direction and find a look you are happy with.
8/ Remove The Selection Marquee
From the top menu, choose Select and then choose None.
9/ Blur The Rainbow
To blur the rainbow, (still working on the Stroke Layer). From the top menu, choose Filters then choose Blur and then choose Gaussian Blur. And from the subsequent Gaussian Blur dialogue box, set a Blur Radius of your choice, and then click OK.
From the Toolbox, activate the Crop Tool.
Then drag a Crop Bounding Box around your text.
And then left-click once in the centre of the image to commit the Crop.
Change The White Background: Tip
To remove the White Background: left-click to remove the Background Layer’s Visibility (Eye) Icon. This temporarily hides the Layer’s Contents - as illustrated below-right.
Fill Layer Tip
Now you have removed the White Background, you can create a Fill Layer, and Fill it with either a Solid Colour, Pattern or a Gradient - as demonstrated by my Create A Fill Layer Tutorial Here.
To finish, from the top menu, choose Image and then choose Flatten Image.
Congratulations, your Rainbow-stroked Text is complete, and is ready to Optimise and Save.
Now you are familiar with this technique, you can have lots of fun creating personalised Rainbow-stroked Text.
