Making a theme for Xfwm4

Just finished creating two variations of a Xfwm4 theme. That’s a lot of work! Not only do you have to come up with some idea as what kind of theme to create (the creative spark, the inspiration) but also have to slice, cut and modify the mockup you finally came up with.

And there are at minimum a whopping 42 XPM-images to a theme! And if you really want to take it that far, you can also create an overlay PNG-image for each of those. So a fully tricked out theme would have a total  84 (!) images you’d have to create.

That’s a lot of work and if you ever created one you know it’s also really repetitive and tedious. Hmm, repetitive and tedious, sounds like the perfect job for some scripts!

Since GIMP is seriously lacking in the slicing compartment I wrote a python-fu script that creates a new image for each visible path. It will set the mode of the new image to indexed, and then save it in the directory you specified, using the name of the path as file name.

That takes care of the slicing, but there is still the matter of editing the created XPMs to include the GTK theme color pickups. So I wrote a shell script to take care of that. You pass it two arguments, the first is the directory where you saved the slices to, and the second is the directory where it’ll put the modified XPMs.

But how does that script map a color in the image to a GTK theme color name? Well, I created a GIMP color palette that assigns each GTK theme color name to a color. If you now draw the mockup in those colors, that script can then modify it.

Since wordpress won’t let me upload tarballs or simple text files, you have to copy/paste the following… :-(

The python-fu plugin will/should add a new menu entry “Xfce Theme Tools/Export paths as index XPMs.”. Just create a few paths, name them, make ’em visible and use the script.

~/.gimp-<your gimp version>/plug-ins/

	get_selection_bounds = pdb.gimp_selection_bounds
	convert_indexed = pdb.gimp_image_convert_indexed
	file_xpm_save = pdb.file_xpm_save

	for vector in image.vectors:
		if not vector.visible:
		r = get_selection_bounds( image )[1:]
		width = r[2] - r[0]
		height = r[3] - r[1]
		copy_visible( image )
		new_image = paste_as_new()
		convert_indexed( new_image, NO_DITHER, MAKE_PALETTE, 255, False, True, "" )
		file_name = path_join( output_dir, "%s.xpm" )
			new_image, new_image.layers[0],
			file_name, file_name, 127 )
		gimp.delete( new_image )

So, that is exactly why I’m sticking to Linux. I can just quickly automate stuff I want done, without having to buy into obscure and messy solutions. Then again, shell and python scripting is considered mastery of the black arts by some ;-P.

Oh, and you can find the Xfwm4-themes I created here:

Leave a comment if you made something cool with it or you have suggestions, I’ll appreciate it!

    Wow man, not only you have done those fantastic XFWM themes, you have wrote scripts to help doing one! SImply great.

    Seriously, love your work. I’ll probe those scripts. Thanks for all, one more time ;)

  2. thezbyg says:

    The python script has bug
    menu=”<Imagegt;/Xfce Theme Tools”
    should be
    menu=”<Image>/Xfce Theme Tools”

    edit: Fixed, thanks ;-)
