Change arrow color

[gogreen]

I've downloaded the script arrow.scm and can use it OK. But the arrow is black and I'd like it to be permanently red. I've found nothing in the script parameters window that allows me to change the arrow's color. How do I change the arrow color permanently? I'm on a 2017 iMac and new to Mac, having recently changed from Windows 10 to Mac. Thanks.

If it is the arrow script that looks like this?



The colour is whatever foreground colour is set. No easy way of setting the colour permanently.

OK. Got it. Thanks.

I've been able to create an arrow to my liking, one with a narrower shaft. How do I make the arrowhead proportionally smaller? Thanks.

Proportionally, the arrow head is controlled by the length of wings (LoW) value, increase that to make the arrow head smaller.

You might want to use fixed values (I prefer this) 
1. Length of wings type LoW pixels with a LoW value
2. Line thickness, change Brush thickness type to BT pixels and a fixed value.

Do not be afraid of experimenting with anything in Gimp

Your friend is always ctrl-z (Mac might be cmd-z) to undo last action

I’m having some problems with the arrow.scm script. First, on the web I’ve found instructions to place arrow.scm in four different places. I’m not sure if some of these locations are Windows—I’m on a Mac. Nevertheless, I’ve placed arrow.scm in my User’s library here: /Application Support/GIMP/2.8/plug-ins. Is this the correct place in MacOS High Sierra 10.13.3?

Also, in the “Script-Fu: Arrow” window, after drawing the arrow, I get the spinning beachball and cannot close the Script-Fu: Arrow window. Is this an installation issue? What am I doing wrong?

Thanks.

Since the file name ends with  '.scm', it is a script, so it goes in the scripts subdirectory (if you put it in plug-ins I wonder what Gimp is executing...). If you go to Edit>Preferences>Folders>Scripts the right pane will list two directories, one is R/W (in your own user directories) and one is R/O (in the Gimp installation).

If you use the "private" directory:

• you can add things there without requiring admin rights
  
• if you share the machine with other people, they won't be impacted by your addition
  
• it is more likely to be part of your regular backups
  
• it won't be lost if you re-install Gimp
  

If you use the directory in the Gimp installation:

• you can share it with other users of the machine
  

So in general, it is best to use the "private" location.

This is also true of other additions: brushes, patterns, gradients, and at least the simpler plug-ins (Python ones).

Script-Fu crashes when I create an arrow. After drawing an arrow, I get the unstoppable spinning beachball. I can continue working in GIMP, but the script will not close and the spinning beachball won't stop. I uninstalled GIMP, restarted, and reinstalled both GIMP (2.8.22) and then the arrow.scm script. The problem persists. Did I miss a setting in MacOS or in GIMP? Thanks.

Going back to your first post and the script worked.

What has changed since that earlier time? Any Mac updates for example.

Good question. The last MacOS update was January 24--before I noticed the problem. I don't recall any other changes. The script draws arrows just fine now. However, after I draw an arrow, Script-Fu goes gray, the unending spinning beachball appears, and I cannot close the script (or draw another arrow) until I close and re-open GIMP.

Addendum: I installed Gimp and arrow.scm on my MacBook Air, and the same thing happened after using the script. Does anyone know if there's a problem with GIMP or the script itself in MacOS High Sierra 10.13.3?
