Nathan's Wallpaper Setter 0.6

August 03, 2011 — BarryK
Nathan wrote this a long time ago (Nathan created Grafpup, a very nice Puppy derivative). The Wallpaper app has been hacked on by various people, including me, and the last version was 0.5.6 -- which is buggy, so I dropped it in favour of Pwallpaper (now at 1.1.2-1) which is an app discovered by ttuuxxx.

01micko and zigbert have been hacking on Nathan's Wallpaper Setter and have released version 0.6, which I presume is in Lucid 5.2.6RC.

However, it has a bug, and I have been trying to refresh my memory about this... it has been awhile... the app has lost the ability to crop images for widescreens.

Woof has rootfs-skeleton/usr/sbin/set_bg, which came out of an earlier Nathan's Wallpaper Setter. It has a modification to crop the image for wide screens.

The original Pwallpaper C source was modified by ttuuxxx to call set_bg (then by me to specify path /usr/sbin/set_bg) -- see pwallpaper.c in pwallpaper-1.1.1.tar.gz in my sources repo.

The latest Nathan's Wallpaper is calling it's own internal /usr/local/apps/Wallpaper/set_bg, which doesn't have the image cropping.

Note also, the original image gets moved to /usr/share/backgrounds_original.

The fix seems to be simple, just get Nathan's Wallpaper Setter to call /usr/sbin/set_bg -- I did a quick test, seems to work ok.

I'll send a pm to 01micko to get the app upgraded with the fix.

gtkdialog version

Note that Wallpaper 0.6 does not work properly with the gtkdialog that we have been using up to now, it needs at least this: However, thunor, the guy who is doing much of the work improving gtkdialog, has actually bumped the version number to 0.7.21, so the next PET I create will have that number (intend to do that tonight). I also plan to name it '', that is, drop the "3" off "gtkdialog3". So, I have some advice for all developers who are using thunor's improved gtkdialog, when you create a PET please put in the dependencies field: [i]|+gtkdialog&ge0.7.21|[/i] Woof now supports versioning of dependencies. There is the question of backwards compatibility I do hope that thunor's enhanced gtkdialog is still compatible with all the current packages/scripts that use gtkdialog3. I really don't want to have to name thunor's app as 'gtkdialog4'!

"Hi Barry Ok, I updated to 0.6.1 with widescreen cropping re-enabled. I took a slightly different approach for backward compatibility, since the wallpaper setter works in Puppy-4.2.1 with your older wary (rev-73?) gtkdialog pet and the addition of libgio. (probably 421 too). I moved the correct set_bg script into the wallpaper directory but added a test for existence of /usr/sbin/background_reshape (see comment in script, legacy). I left out the fancy menubar stuff (left the basics), calls are made to default apps anyway so I couldn't see the point in having it (you'll see what I mean if you do a diff) Also added the [i]+gtkdialog&ge0.7.21[/i] to dependencies field.
