[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 don't usually open the error console, but I see the same behavior in linux with the console open.

I created a second much simpler path with Free-Select-Tool then converted to path and named it Path_B. With the two paths it showed: Length of Path_B: 383 px. It appears (based on swapping order of paths with drag+drop) that it always shows the length of the lowest path (the one a the bottom of the list) For me, it gives the length of whatever path is selected in the paths dialog.

Re: [Gimp-developer] Creating a layer from a selection or pasting to a specified x, y coorinate
OK, I think I have solved my problem. You have to know what to search for in the pdb. I think this will do what I need: pdb.gimp_layer_set_offsets There is nothing in the pdb browser for moving a layer, you have to offset it.

Note to all users of GIMP 2.6: The gimp-2.6 releases that we have done so far will not work with GEGL 0.1.0 (or babl 0.1.0). This is not because GEGL would be incompatible, but rather because of a stupid bug in the run-time version check. This is fixed in git and we plan to do GIMP 2.6.7 release with this fix soonish. There are however a few more patches pending that we'd like to get into 2.6.7 as well. So give us a few more days...

In linux and XP (both 2.6.6), it reports the length of whichever path is selected in the Paths dialog. I also fixed the 'Repeat' and 'Reshow' weirdness, and also disabled the plug-in when no image is open. Let me know how it works out...

If you need an image parameter, then you should have PF_IMAGE in your input parameters. If you also need a drawable, then this should be followed by PF_DRAWABLE. But these are by no means obligatory. If you don't need an image nor a drawable, then you can safely omit them.

When using the old, unnamed register() parameters, if you leave 'params' empty, the main plug-in function still receives two parameters - the current image and drawable. Using the new, named register() parameters does not seem to do this anymore. No big deal really, but I thought it odd that the behavior would be different.

That is exactly the odd quirks mode for backward compatibility that I mentioned. If you use the old register() API, then parameters are added for you depending on the menu location your script is registering to. As that is hard to understand and frequently leads to automatically added parameters that the script does not actually need, this behavior was changed. It is still there, for backward compatibility, if you use the old API though.
