Re: [Gimp-user] A request for your input.
I have a issue about a couple of your questions. The one that prompted me to write this note is the one that says: [quote] Members of the open source community generally agree that 1) You will make money by working on open source projects. [/quote] This somehow strikes me as a loaded statement. The answer is obviously 'strongly disagree'. For instance, I've written a game, it is open source and GPLv2 or whatever GPL version you choose. I did not make any money because of it. There was no open source fund that I was drawing from in order to write this game and make it available free over the internet. Where's my pot of money for doing this? I believe that the proper way to state this is and get a variety of answers is: 1) You CAN make money by working on open source projects. -- Tony [EMAIL PROTECTED] wrote: > Hello > > My name is Lara Thynne and I am a PhD candidate at Deakin University > Australia.

Re: [Gimp-user] Unable to use 'system' command for script-fu <-- Almost done
Almost done!
One last thing that I cannot figure out is: how do you close the dialog
box that the image is sitting in? In Scheme you do it like so:
(gimp-display-delete Image)
I've tried the following (with variations), but it causes the python-fu
to hang:
pdb.gimp_display_delete(img)
Anyway ... here's the code so far:
#!/usr/bin/env python
# Send to Web - Re-samples an image, adds drop shadow, and saves it
# to ls1 www images directory so that it can be used
# in a 'Top News of the Day' article.
import os
from gimpfu import *
def python_send_to_web(img, drawable, filename):
img.disable_undo()
# local variables:
SRCFilename = "/tmp/" + filename
RemoteDirectory = "ls1:/home/tony/"
SCPProgram = "/usr/bin/scp"
width = img.width
height = img.height
# hack to make the next section work:
blank_layer = gimp.Layer(img, "blank", width, height, RGB_IMAGE, 0,
NORMAL_MODE)
img.add_layer(blank_layer, 0)
gimp.displays_flush()
# merge all the layers for just in case the user has done some editing:
pdb.gimp_image_merge_visible_layers(img, 0)
# screwed up the drawable when I merged the layers:
drawable = pdb.gimp_image_get_active_drawable(img)
# scale the image if it's too big:
if (width > 470):
newheight = ((height * 470) / width)
pdb.gimp_image_scale(img, 470, newheight)
gimp.displays_flush()
# add a drop shadow:
pdb.script_fu_drop_shadow(img, drawable, 8.0, 8.0, 15.0, [0,0,0],
80.0, TRUE)
gimp.displays_flush()
# final layer merge:
pdb.gimp_image_merge_visible_layers(img, 0)
drawable = pdb.gimp_image_get_active_drawable(img)
# save the image in png format to disk:
pdb.file_png_save2(img, drawable, SRCFilename, filename, FALSE, 6,
TRUE, TRUE, TRUE, TRUE, TRUE, FALSE, TRUE)
gimp.displays_flush()
# close the python-fu dialog box:
gimp.delete(img)
# send the image to our ls1 directory:
command = SCPProgram + " " + SRCFilename + " " + RemoteDirectory
os.popen(command)
# user needs some feedback:
pdb.gimp_message("Cool! Your picture is online. You may now
include it in a 'Top News of the Day' article.")
# I'd like to be able to close the dialog that the image is sitting
in ...
# but I cannot figure out how to do this. I'll leave it open.
Hopefully the
# user will not be too confused by this.

Re: [Gimp-user] Unable to use 'system' command for script-fu
Thanks for all the comments, I guess I'll investigate python-fu. I do not see a tutorial on the gimp website for python-fu (http://www.gimp.org/tutorials/#Script) so I'll be doing some googling ... would anyone happen to know of a good basic tutorial I could check out?

[Gimp-user] Script-Fu Question about Saving Image to Network Share
Hello,
I'm writing a script-fu for use in my office. The idea is to reduce the
amount of steps the user needs to take in order to save an acquired
screenshot to our website.
*
*The problem I am having is that I cannot seem to save a file to an
smb:// type address. This is the error I get when testing:
*[error]
*Could not open 'smb://ldad_images/screenshots/web-image.png' for writing: No
such file or directory
Error while executing
(script-fu-Send-to-Web 1 "smb://ldad_images/screenshots/" "web-image.png")
ERROR: Procedural database execution failed:
(file_png_save2 1 1 5 "smb://ldad_images/screenshots/web-image.png"
"web-image.png" 1 9 0 0 0 1 1 0 0)
*[/error]*
The script works just fine if I save the image to a local drive such as
'/tmp/'.
Also, if I type this in a terminal:
nautilus smb://ldad_images/screenshots/
A file browser opens just fine into the shared 'screenshots' directory.
If saving to a network drive is not possible (such as smb://), is there
some other trick I could use to get the image over there?
Suggestions would be helpful :-)
Here's the code I have thus far:
*[code]
*(define
(script-fu-Send-to-Web Image Location Filename)
; the directory our file will be saved in
(set! SRCFilename (string-append Location Filename))
; scale the image to our optimum web size
(set! width (car (gimp-image-width Image)))
(set! height (car (gimp-image-height Image)))
(if (> width 470)
(begin
(set! newHeight (/ (* 470 height) width))
(gimp-image-scale Image 470 newHeight)
(gimp-displays-flush)
)
)
; add a drop shadow
(set! drawable (car (gimp-image-get-active-drawable Image)))
(script-fu-drop-shadow Image drawable 8.0 8.0 15.0 '(0 0 0) 80.0 TRUE)
(gimp-displays-flush)
; save as png file to our www directory on ldad (or wherever the user
indicated)
(gimp-image-merge-visible-layers Image 0)
(gimp-displays-flush)
(set! drawable (car (gimp-image-get-active-drawable Image)))
(file-png-save2 RUN-NONINTERACTIVE Image drawable SRCFilename Filename
1 9 0 0 0 1 1 0 0)
(gimp-displays-flush)
; Close out the image
(gimp-display-delete Image)
; Let user know it's online
(gimp-message "Cool! Your picture is online. You may now include it
in a 'Top News of the Day' article.")
)
; Register the function with the GIMP:
(script-fu-register
"script-fu-Send-to-Web"
"/NWS/Send To Web"
"Scales the image to 500px width and saves it to www images rsync directory
