Episode 053: In the USSR the Posters are watching YOU!

I have to do some corrections on last weeks episode. As I wrote in the update, I had made a blunder with the last layer.
Then we have another video from Andrew A. Gill, the guy who enlightened us about CYMK. He takes on the Comic style from episode 50 and tries to copy a style used by Soviet propaganda and today by Shepard Fairey. +Link +Link
The image on top of this post has been made by Andrew. It’s not exactly Soviet Propaganda. 😉
Then I have a challenge for you. I got set of images from Ted. He is researching family history. So he has to work a lot with reproductions of old documents. The rules are easy: You are happy about what you get and you don’t complain about quality. Here is a set of images (11MB) for you to cut your teeth in. The goal is to enhance readability. Please document your steps. Next week I’ll tell you how to report about your results.

Finally there are some news about GiMP 2.5.2.

How to install GiMP 2.5.2 on Ubuntu 8.4

According to billstei in this comments it should work this way:

(This is a compilation of his three postings, I haven’t tried it.)

I was able to compile and install Gimp 2.5.2 (alongside the normal Ubuntu Hardy Gimp 2.4.5, so I have both at once) by following the instructions here: http://www.gimpusers.com/…

However I did the following differently:

1) I did not find it necessary to compile GLib or GTK+ as the ones already in Ubuntu Hardy were fine. So I only compiled babl, gegl, and gimp.

2) In step #5 the only export that you need for compiling is this one:

export PKG_CONFIG_PATH=/opt/gimp-2.5/lib/pkgconfig

Both the gegl and gimp configure steps will demand that you do that export first, or it will complain that you do not have babl. Make sure that you actually do have the babl you just created installed first, or else it will be correct when it tells you that you don’t have it :)

Then to run the program I made a shell script like this (per the advice on the Gimp website here: http://gimp.org/release-notes/gimp-2.5.html )

#!/bin/sh
 PATH=/opt/gimp-2.5/bin:$PATH
 export PATH
 LD_LIBRARY_PATH=/opt/gimp-2.5/lib
 export LD_LIBRARY_PATH
 /opt/gimp-2.5/bin/gimp-2.5 “$@”

Whatever name you give to that shell script file is the one you use to start Gimp 2.5. Remember to do:

chmod +x [whatever-you-called-it]

so you can execute it.

3) I prefer to use deb packaging where possible and so I use the program “checkinstall” rather than doing the “sudo make install” step for each of the 3 compiles. Checkinstall is a little buggy at times so you may not want to use it, but if you do here is some advice:

3a) Checkinstall will fail until you create some directories ahead of time (there may be some I missed, but checkinstall will let you know):

 sudo mkdir /opt/gimp-2.5/share/locale
 sudo mkdir /opt/gimp-2.5/share/icons
 sudo mkdir /opt/gimp-2.5/share/icons/hicolor
 sudo mkdir /opt/gimp-2.5/share/gimp/2.0/fonts

3b) Checkinstall will list 10 options, and option line #2 is the name of the package itself, which will be by default “gimp”. Since you already have “gimp” installed as Gimp 2.4.5 you will have to change the package name to avoid a conflict, to something like “gimp-2.5″ or similar, just so it’s different.
4) Start checkinstall like this:

sudo checkinstall --install=no

Then when it finishes you will get a deb, which you can install like this (babl package shown, similar for the others):

sudo dpkg -i babl_0.0.22-1_i386.deb

and of course the advantage is that this will show up in Synaptic if you later decide you want to get rid of it (or upgrade it).
I wish I could say all this is “easy”, but perhaps not. If it seems confusing, then just stick with the original instructions and not mine.

According to the weather report I have a lousy weekend in front of me, (my Croatian friends: it’s afternoon and 16°C in front of my window….. 😉 ) so perhaps I’ll give it a try.

New in 2.5 (2.6) “hybrid polygon/free select tool”!

David gowers wrote a comment that I pull to the front page.

Another exciting thing that will be in 2.6 (and the next 2.5 release) is the hybrid polygon/free select tool! It is truly a thing of beauty, the way you can edit it as you go, easily rotate or scale any freehand section by moving an endpoint, or edit a polygonal segment just by moving an endpoint — and no longer requiring the entire selection to be completed in one stroke is also great! It might be an interesting topic to cover as part of a future show.

Anyone who is curious, also, I strongly recommend you get a SVN checkout of the latest GIMP and try it! It’s worth the effort.

I’ll do that – sometime next week.

Episode 042: Don’t Panic!

This time I am not in Bremen but in Seefeld near the North Sea. I was there for a weekend training in school management.

The show starts with a live view at Gimp 2.5.0. Tobias Jakobs sent me a video about some new features and I add another one. This is alpha software, keep away if you are not helping with debugging. And never do “real work” with it.

Tobias Jakobs is well known in the German Gimp community for winning an image manipulation contest ahead of all the Photoshoppers.

Seefeld is in a nice area, as you can see from the aerial view. A lot of fresh air and the sea near by. We had not enough time for long walks but I could grab the shot above. You’ll see how I made that out of a pretty boring original image The original shot with a bit of curves and the healing tool. You can download the original and the processed shot in their full size at 23hq.com.

You all know Joseph AKA bluemojo. He covers the Foreground Select Tool and shows all the details. He also has a link covering the SIOX algorithm behind it. For all concerned minds – he dug his three girls out before the tide came in. 😉
