Episode 110: Some new Paths (2)

Made by Seth/W_NightshadeToday I go into the details of the path tool. It has a real lot of different modes and states – so one gets easily confused. I try to sort that out – but you’ll have to train yourself to master this.

Seth aka W_Nightshade has made a video about making ambigrams with paths. You see the one he did here on the side. I couldn’t make a show out of his video – but you’ll get a fast version of it with music in the video and if you are interested can download the whole package in the companion file. The music is from John Pazdan, the composer of the podcast music.

I start with a book review. Akkana Peck‘s book “Beginning GIMP – from Novice to Professional” is gone into a second edition. And now it’s even better than before. If you are looking for a book about GIMP – this would be my first choice. Apress has given me the second edition book – I bought the first one before starting with this project.

And I have two of the books to give away. To you. We’ll make two challenges, one from Philippe, one from me. And Apress will send a book to each of the winners.

The Wacom button problem is discussed in this forum thread. Look in the later pages for the script – it’s there in several incarnations.

  1. I really wish I could have gotten some audio to you for that video, but I am really looking forward to watching this episode – -I have it queued up on my iPod, ready for my commute home (train, not car – that would be dangerous!).

  2. Maybe a little hint relating the path tool: When selecting an object in design-mode, just hold (beginning from second node) the left mouse button pressed between adding nodes (while following the desired form with mouse pointer). This generates corresponding Bezier-handles automatically (so you need the edit mode less often).

    You can see a similar technique with Photoshop’s pen-tool (found no GIMP counterpart ;-) in the following video (start at 1:20): http://www.youtube.com/watch?v=Zn2JZMG2t1Y

  3. @Tobias: Oh, yes, I forgot that.

    @w_nightshade: I hope you are not too mad about me because your video is reduced to an intermezzo. (But your pachkage has been downloaded 50x already.)

  4. Rolf, you successfully reduced my fear of contact concerning this complex tool. Thanks!
    w_nightshade, your art is jaw-dropping!!

  5. No, Rolf – I was actually really pleased with how well it translated in that format. And I am glad folks are taking a look at the process – I find it interesting, and it is nice to know I am not the only one.

    My content aside, that was one of my favourite episodes to date. Thanks for letting me get involved!

  6. P.S. Bert (or anyone else), I design these for fun, so if you would like me to do one for you, let me know. Forums are probably best, as I check the blog only occasionally.

  7. Also (am I posting too much?) a couple tips for using the paths tool:

    1) to get a symmetrical curve, you need to make the handles for two adjoining nodes parallel. If they come straight away from the segment (i.e. perpendicular), and are the same length, you get a nice semi-circular curve.
    2) As you explain in the episode, holding shift while dragging a handle makes it’s mirror handle symmetrical so the curve is smooth. But you can add fine tuning by changing the LENGTH of the handle. As long as the ANGLE is the same as its partner, the curve will remain smooth, but one side will be shallower than the other.
    3) When stroking paths that contain sharp angles, don’t forget the thickness of the line when setting up your path. A sharp angle’s vertex will jut out significantly past a similarly lined-up straight line. You can see this happen in the first shape I draw in my ambigram video.
    4) You can join two nodes temporarily to move several disconnected paths at once, then remove the joining segments when placed.
    5) Stroking along paths using different brushes or lines thicknesses and colours, each on thier own layer, can be used to make some excellent lighting/shadow effects. And because you are simply stroking over a path, it is fairly non-destructive, so… experiment!

  9. Hi Rolf,

    would it be posible to leave some Coments in one of the next shows what grafictablett is nice for gimp. Maybe the advantages or disadvanteges of such hardware.
