Introduction to GIMP Brushes
Brushes are a very good and effective tool for art and illustration in any designing work same as in GIMP, we use brushes for many different purposes, such as in image manipulation, which includes hiding some area of any layer, making patterned line, or any particular shape or artwork in just one click and many more. Like other software tools, we have a number of parameters of this tool, and by changing them, we can have lots of variety in working of this brush tool. So I think you’re excited now for analyzing these features of the brush tool for getting good hands-on.
How to use Brushes in GIMP?
Working features and using this tool is quite simple because you can play with it with just a few simple clicks, so let us see what these clicks are.
Go to the tool panel, and you will have brushes with the name Paint Brush tool, so click on it or simply press the P button as a shortcut key.
You can also have the Paint Brush tool from the Paint tools option of the Tool Menu of the menu bar.
Once you have activated this tool, you will have this dashed circle cursor on your screen.
You just have to choose the first point by click anywhere on your document area or from where you want to start, then drag the mouse by holding that click. This way, you can use any brush tool. Isn’t that very simple?
Now let us have a look at the parameters of brushes.
- Parameters of brush tool:
We have a number of parameters in the brush tool, which includes opacity, hardness, size, aspect ratio, angle and some others.
Hardness means how hard edges of drawn shape will be with the brush tip of the brush tool. I draw this with hardness 50%.
Now changes the hardness to 100% by choosing it from presets of brushes.
And draw it again. You can see the difference between both of them; the second one has the hard edge due to the 100 % hardness of the brush tip.
You can also choose any preset pattern from this list, and when you draw anything with a brush, then you will get your chosen pattern stroke like this.
Size refers as the size of the tip of a brush. You can increase or decrease it as per your requirement anytime.
- Aspect Ratio:
Aspect ratio means the ratio between width and height of brush tip. If you increase this ratio, you will get this type of brush tip that has an oval shape compared to a normal brush tip.
By changing the angle, you will change the angle of the brush tip. See the difference between both brush strokes. The first one is at 0 degree, and the second one is at 55 degrees.
It defines a distance between pattern drawn by brushes. The top stroke of the brush is drawn at 10 spacing, and the bottom two are drawn at 91 spacing, so I think you understand what is spacing by seeing this.
We have discussed hardness above, which is our next parameter here; you can give the value of hardness as per your choice.
These are few important parameters of brushes. Now let us learn how we can have custom brushes in GIMP.
