I request people to please post your requests in forum rather than sending me a direct email. I visit gimptalk forum all the time.
NOTE : This tool is not written by me, I am just a user of it as you are.
Before reading the tutorial below, download the great utility form following link
Here I will try to demonstrate some for windows users since I am windows user and have no idea how it works on other platforms.
First of all make a new folder in root of your drive C (I am sure you can do that). Name the folder gbr
1. After downloading the zip file just extract abr2gbr.exe to the newly created folder C:\\gbr.
2. Now put all the .abr and .jbr files also in the same folder named gbr.
3. Run the command prompt, by using button Start on taskbar, and then click Run, a new window will appear asking you what to run, type
in this textbox (only the word 'command') and press enter key.
You will now see a console window (black window).
4. Type in C: and press enter
5. Type in cd\\gbr and press enter
Now you will see something like C:\\gbr> and a blinking cursor.
Finally, suppose you have an .abr file named 'gimptalk.abr' and you want to convert it to .gbr version, simply Type:
and you are done.
Go to the folder C:\\gbr through 'My Computer' icon on desktop or Windows Explorer, and see if there are .gbr (GIMP brush files), it means conversion succeeded, otherwise (if not) it definitely means that the brush files are of a new vresion that cannot be decompressed by utility abr2gbr for conversion.
Now, question is how to use them in gimp?
Answer is simple.
Copy all the converted .GBR files to brushes folder of gimp
or if you have installed gimp in some other folder, then use
and restart the gimp (if already running), or simply rightclick within the brushes windows and select menu item Refresh.
BTW : I am writing a front-end gui for this great utility which will allow you to select folders (containing .abr .jbr files), and do the bulky conversion transparently. wait for that :w:
I hope it helps.
