Hi everyone!
In my project, I have a lot of image files, that I wanted to process using
a different tool. For this, after reading some posts about custom merge
drivers in this forum, I make the following modifications:
In the file .gitconfig I added the following lines:
[merge "imgfile"]
name = Driver for image files
driver = /usr/local/bin/git-merge-img.sh %O %A %B %L
recursive = binary
and in the .gitinfoattributes I put:
*.png merge=imgfile
As I can see, it works calling my custom script during a merge between
two branches that have a .png file. Unfortunately, even after a successfully
merge, the final image is not merged with the one in the other branch.
In order to test it, I've called my script using three images, giving me the
corrected result.
I don't know if it could help but instead of changing the content of the file
I create another one with the same name during a merge operation.
Does anyone could help me pointing what could be wrong with this?
Thanks a lot!

I have my image merge script configured it like this:
[merge "imgfile"]
driver = imgmerge %O %A %B %A
but if you do that, you must be sure that the script does not need to
access $2 after it has begun writing to $4.
(I know that it worked because at one time I had forgotten that I have a
custom merge driver, and was expecting a merge conflict due to an image
file, but there was no conflict, and the result was correct ;-)

Hi Johannes,
Thanks a lot for your help.
I have checked it and I'm writing to the right file after reading the data from
it. According to what I see, only the modifications made on the current
branch are saved, even after applying the delta to the right image file.
One question is: does it matter if I save the whole file, replacing the old with
this new one? Or do I need to open the old one and modify its content?
Thanks again!
