Using Gimp - More Fun with Brushes


As our last meeting was short, due to the lack of heating, here are a few brief notes on making your own brushes.  Most Gimp users have used the Brush Tool at some time but most of us have never explored its full potential.  Any image can be converted into a brush.  The brush can then be used rather like a rubber stamp to make individual copies of the image, of any size, anywhere you like.  You can also programme the dynamics of the brush so that with a single stroke you can draw a line of images of varying spacing, size, colour, - - - - - - , the list is almost endless.  In the example above I have used a flower photo taken in my garden to make two brushes.  The first was saved as .gbr ("gimp brush") format, the second as .gih  ("gimp image hose") format.  See "Adding New Brushes" in Gimp Help https://docs.gimp.org/en/gimp-using-brushes.html  .  These brush files must be saved in the users Brushes Folder.  To locate this in Gimp go to Edit > Preferences > Folders > Brushes and look for the brush folder setting.  For Linux users this may be /home/*****/.gimp-2.8/brushes where ***** is your home directory name.  Microsoft Windows users it may be /C:/Users/****/Application Data/GIMP/2.10/brushes.

The Robin image was hand drawn using mainly the circle select tool and Bucket Fill.

In the example above I made a .gih Brush using an image with four layers of different colours.  I then set the spacing and dynamics of the brush to give the effect of a stream of flowers flowing from the watering can.  Note that this effect is produced with a single stroke of the brush!

If you want to know more about brushes in Gimp have a look at the Gimp help pages or come to the next Gimp Group meeting.  If you have any questions let me know beforehand so that I can prepare my defence!
