[Gimp-user] python script for rectangle selection

2010-01-02 Thread Fab 
Hi,

I am new to gimp's scripting and would like to automate the rectangle
selection tool by defining the position and size using a script.
Afterwards, I would like to extract the selection, 'paste as new image' and
save the image as a png file without compression.

It would be nice, if you can give me some hints, how to achieve this. Maybe,
something similar exists already!?

Thanks in advance!
Fab

I am sorry that I cannot produce a script but why not put the question
to  http://forum.meetthegimp.org/ there are some very knowledgeable and
helpful script writers there.

 Hi to both,

 thanks for your help and thanks for the script! I tried the attached python
 script
 by using execfile(script.py) from the python-fu console. Unfortunately gimp
 (2.6.7 on ubuntu) crashed. Do you have a hint, what I am doing wrong!?

Yes - that was originally written as a plug-in (place in
~/.gimp-2.x/plug-ins, chmod +x, it registers as 'File-Export Area').

I think this code should work in the console - either via execfile or
typing/pasting it in.

Chris

import os
from gimpfu import *

# size and position of rectangle
areaWidth = 200
areaHeight = 200
areaPosX = 20
areaPosY = 20

# path to save PNG
path = os.path.join(os.path.expanduser('~'),'Desktop')

# operate on first image
img = gimp.image_list()[0]
filename = img.name + -sm.png
fullpath = os.path.join(path, filename);
tmp = img.duplicate()
tmp.flatten()
tmp.crop(areaWidth, areaHeight, areaPosX, areaPosY)
pdb.file_png_save(tmp, tmp.layers[0], fullpath, filename, 0, 9, 1, 1, 1, 1, 1)
#pdb.gimp_image_delete(tmp)

You should be able to do this using David's Batch Processor. It will let
you define a fixed region to crop from an image and save as png, then
apply that to multiple images. No scripting necessary. Google DBP.
