Re: [Gimp-developer] debugging and print messages in PyGimp for windows
So, the --verbose option definitely pops up a dos-looking window and prints lots of GIMP related messages, but it doesn't seem to get error messages from Python. I just accidentally tested this with a syntax error in a module of mine that my PyGIMP plugins import. In linux I get this very helpful message: r...@am2|07:02 AM|09_02_09$ gimp Traceback (most recent call last): File /home/ryan/.gimp-2.6/plug-ins/pygimp_lecture_utils.py, line 1, in module import os, rwkos, rwkmisc, re, time File /home/ryan/git/krauss_misc/rwkos.py, line 9 if not amiLinux() ^ SyntaxError: invalid syntax (gimp:17913): LibGimpBase-WARNING **: gimp: gimp_wire_read(): error and I can fix that in 30 seconds or so (it is a stupid syntax error on my part, missing the trailing colon). But in windows, I see no message related to it at all. The only indicator of a problem is that none of my PyGIMP plugins show up in the menus at all (none of them can register themselves because they all import this module). No idea how long it would take me to find the exact line that caused the problem if I didn't try it in Linux. Is there an easy solution to this? How do I get standard error messages from Python to display in Windows XP?

Re: [Gimp-developer] PyGimp on Windows XP
So, I found this http://www.gimpusers.com/tutorials/install-python-for-gimp-2-6-windows.html and think I am going to get things working. It turns out that even though the GIMP installer will let me intall Python as long as PyGTK is installed, it also needs PyCairo and PyGObject to actually work. And the confirmation that it is working is a Python-Fu menu item with an option to launch a console under Filters.

[Gimp-developer] PyGimp: letting the use pick coordinates
I am using the GIMP and a Wacom tablet as a digital blackboard for a course I am teaching this summer. With Python and PyGimp, it is going really well (other than my bad hand writing made worse by the tablet - it is weird writing on the tablet and having to look to the screen to see what you have written). Example lecture notes can be seen here: http://home.cs.siue.edu/rkrauss/452/lectures/07_02_09/index.html We are coming into a mathematically intensive part of the course and I feel like my handwritting has become a barrier. I am creating my own text tool that use Latex and dvipng. The hard part is already done: I have a wxPython application with a text control and a png preview portion and it is basically working. I am now working on better GIMP integration. Right now I type in the equations in my wxPython application and preview the png there. When I want to paste the png into my lecture slide, I have to switch back to GIMP and press a key that is a short cut for a PyGimp script to load the cached png. Then I position it on the slide with the move tool. Not bad, but not as nice as Gimp's text tool. I would like my Latex enabled approach to act like the regular text tool. The main thing I don't know how to do is allow the user (me) to click on a spot on the current image and pass those coordinates to PyGimp so that I can use that as the top left corner of my png. Does my question make sense? Is there an easy way to allow the user to click on a spot on the image and get the coordinates from PyGimp?

[Gimp-developer] Creating a layer from a selection or pasting to a specified x, y coorinate
OK, so following Alexia's suggestion, I am going to plan on selecting ahead of time the rectangle I want my text to paste into. The upper left corner of this selection will then be the upper left corner that I want to paste my png to. How do I do that? I thought about creating a layer the same size as the selection rectangle and pasting to (0,0) on that layer. I see in the pdb how to create a layer with a certain width and height, but I don't see how to specify the offset. And I don't see how to paste to a specific set of coordinates. Can this be done? If I use pdb.gimp_edit_paste_as_new, can I get the coordinates of the pasted selection and then move the floating selection before anchoring? What is the right approach?

OK, I think I have solved my problem. You have to know what to search for in the pdb.

Re: [Gimp-developer] API for bringing up a Save dialog
This is mildly hackish, but my approach is to pop up a Tk save as dialog:
filetypes = [('png files', '*.png'), ('jpg files', '*.jpg'),\
('all files', '.*')]
def save_as(initialdir=None, initialfile=None):
filename = tkFileDialog.asksaveasfilename(initialdir=initialdir, \
initialfile=initialfile, \

return filename
It would prettier to do a wxPython gtk one, but that requires a parent frame
AFAIK.

Of course, this being python, I could put up my own save-as
dialog and let the user choose the filename that way, then call
gimp_file_save() on the result; but I'd rather go through GIMP's
standard framework, with the File Type menu and other nice features.

Any particular reason you are not using a GtkFileChooserDialog? That is
the dialog that the GIMP user expects and knows to use. GTK+ is the only
toolkit that you can definitely rely on being installed and available.
GTK+ is part of the GIMP plug-in API.

[Gimp-developer] PyGIMP question: saving PNG and XCF versions of the same image
I have a Python Gimp question. I don't know if it belongs on the user or
developer list, but my feeling is that the people with the knowledge are
more likely to read this list. Let me know if this is the wrong list to
post to.
I have written a script to create PNG and XCF versions of an image I want to
save. I have a certain layer whose visibility I want to turn off before I
save the PNG but I also want the XCF to give me more editting power if I
want to alter the image later. I have this working fairly well, but the
problem is that when my script finishes, I am looking at the flattened PNG
version of the image. At that point, I would need to close the PNG and
re-open the XCF if I want to edit the file. This is less than ideal. I
think it could be solved by simply doing one undo step after saving the PNG
(since flattening was the last thing I did), but I don't see in the
procedural database a way to undo from a script. Is there a way to save a
flattened PNG and then save an unflattened XCF of the same image and leave
the XCF open?
Here is my code:
from gimpfu import *
def my_save(img, drawable):
ind = find_graph_ind(img)
if ind:
img.layers[ind].visible = False
filename = save_as(initialdir=folder, initialfile=new_name)#--- get
filename from Tk dialog
print('filename = ' + filename)
if filename:
pne, ext = os.path.splitext(filename)
xcf_path = pne+'.xcf'
pdb.gimp_xcf_save(1, img, drawable, xcf_path, xcf_path)
flat_layer = pdb.gimp_image_flatten(img)
pdb.gimp_file_save(img, flat_layer, filename, filename)#---
filename ends in .png
#pdb.file_png_save(img, flat_layer, filename, filename, \
# 0, 0, 0, 0, 0, \
# 1, 1)
#pdb.gimp_image_clean_all(img)
#gimp.displays_flush()
Thanks,
Ryan
