Math would be useful only when you decided to do some complicated calculations within your plugin using python.

I haven’t checked the code yet, no time at the moment and sitting on the wrong machine. But it looks OK at first glance.

I’ve been trying to create a gimp script with python to create a border, and I just cant figure it out. I’ve yet to add the actual border creating part of the script, but i DO have a script that I believe would create a new layer. I put my .py file into the gimp “docs” folder, and reloaded gimp, but nothing shows up. Here’s my script so far –

#! /usr/local/bin/python

import math
from gimpfu import *

def add_border(img, drw):

img.disable_undo()

#program

layer_base = drw.copy(True)
layer_base.mode = NORMAL_MODE
layer_base.name = “Border”
img.add_layer(layer_base, -1)

img.enable_undo()
gimp.displays_flush

register(
“add_border”,
“Add a border to your text”,
“Add in the color once script is run”,
“Matt”,
“public domain”,
“2009″,
“/Filters/Artistic/A_dd Border”,
“RGB*, GRAY*”,
[],
[],
add_border)

main()

I’m not really sure what’s up. Please help!!

pdb.plug_in_map_object (img,layer_ovoid,
# mapt vpx vpy vpz
1, 1, 1, 2,
# posx posy posz 1staxisx 1staxisy 1staxisz
1, 1, 1, 1, 0, 0,
# .. and so on..

(spacing in the above may be incorrect)

Gimp Users would be the right list, I think.

Thanks for the response, I have a hard time imagining how I could keep up with a site like this.

You have lots of integers (1 2 3) in your parameters. Perhaps some of them are floating point numbers. In this case you would have to write 1.0 instead of 1.

img.disable_undo()

layer_ovoid = drw.copy(True) #make layer copy
layer_ovoid.mode = NORMAL_MODE
layer_ovoid.name = “Ovoid”

img.add_layer(layer_ovoid, -1)

pdb.plug_in_map_object( img,layer_ovoid,1,1,1,2,1,1,1,1,0,0,0,1,0,0,0,5,1,(255,255,255),-1,-1,2,-1,-1,1,1,1,1,0,27,True,False,False,True,1,0,0,0,0,-1,-1,-1,-1,-1,-1,-1,-1 )

img.enable_undo()
gimp.displays_flush

Cheers.

Good tutorial. I know you are not using windows but the link below describes some of the troubles real people had installing Python into GIMP ( if that is the correct terminology.) I think you described the easy part of using Python in GIMP once installed. The hard part appears to be installing the software. Anyway thanks and maybe a simple script-fu tut. might be more useful since it already appears to be in GIMP.

Btw, I’m a programmer too (I’m focused on ms .net stuff, not for preferences but for my job’s characteristics, but I’ve learned some python along the way).

The article is fine -among other things- because gets you to typing code in a smooth way, as you don’t have to be afraid of what programming is.

@Joseph & Serge: I’ll look if there are such collections except the gimp.org repository. I think it would not be prudent to clutter that with such one-liners. But if something turns out to be good it should be put there additional.

If I don’t find anything suitable I’ll set up a separate Blog at plugins.meetthegimp.org with a possibility to write articles for all.

Luv the show, Enjoy!!

As Joseph said, maybe a Meet the GIMP! plugin repository would be helpful.

As far as I am concerned I do not mind these more technical approaches to GIMP. But okay, I am biased: I am a programmer.

Perspective correction is not part of the lens correction. It doesn’t depend from the lens you use but from the angle between film/sensor plane and your subject. If you tilt it, you get these distortions. A correction is shown in the last show with the high rises at the Potsdammer Platz.
