MindSpace diagram and vector drawing app

Hi folks,

After a lengthy hiatus, it looks like I might have a bit of time to work on MindSpace over the next few months.

As a starting point, I have recompiled MindSpace 1.3 and the (very early) work done so far on MIndSpace 2. Both programs are in a single archive, currently sitting in the OS4depot upload queue.

MindSpace 1.3a is a drawing app that enables the user to create mindmaps, UML diagrams and daft bits of clipart style graphics.

MindSpace 2 is a complete rewrite and a much more ambitious program (think Inkscape-lite). Key improvements include the ability to work with mutliple views of multiple documents, better colour handling, transparency etc. The current version is very much incomplete, with many key features (such as save/load, undo/redo) not yet implemented. However, there is enough of a program there to play with and to get some feedback on.

There is a fantastically out-of-date 1990s style website for some basic info, screenshots of MindSpace 1.3 etc

Feedback and ideas always welcome, but maybe have a read of the readme files before pointing out things that are already documented... ;)

@yoodoo2
That's great news. I really like Mindspace and I think it is one of the apps we surely need. Are you going to maintain the first version for bugs? Do you consider to open source it, so that people can contribute or learn from your code?

Keep up the good work you are doing.

Thank you Yoodoo2 for spending your time on mindspace once again :)

I like mindspace and it have a really good potential.

@yoodoo2

Thank you for the effort, this programma is becoming better every release :)

On minor thing is that a pdf is connected to your 'wb 41' instead of sys:


And to start it do I have to rename files ?

libfreetype.lha
libfreetype.so.21 to libfreetype.so.16

libpng.lha
libpng16.so.16 to libpng.so.16.20.0

@walkero
Any critical bugs will be fixed in 1.3, but the focus is in getting MS2 more feature complete. The 1.3 code is of such poor quality, that the only thing to learn, would be the wrong way of doing many, many things.

@benny
Well spotted with the pdf default tool
I've still got the old versions of the .so files on my system. You should be able to make links to the newer versions rather than clog up you drive with multiple copies of the same file or rename newer versions. I'll check that works later and update the readme if appropriate.


So after a quick check:

Current version is linked to libcairo.so so the following are needed
libpng16.so.16.20.0 which can just be a softlink to libpng.so
libfreetype.so.18, which can just be a softlink to libfreetype.so

eg makelink sobjs:libpng.so.16.20.0 sobjs:libpng.so
etc

@yoodoo2

Have played a little bit with MS2 and it looks promising. The urgent features are load, undo, freehand, curve, IMO.
What I really, really like is a borderless toolbar, without close, resize, etc. gadgets. Eets less space which is very important plus it looks clean and orderly. You have put a lot of effort in a toolbar preferences. Now drawbacks ;) I tried all tools and after some time they stopped working. When I open a second project window and then try to close the first one I have a crash. Need to learn a little bit more before further comments. :)

@mr2
Thanks for having a look.
Glad you like the freedom to set up the toolbars as you prefer them..
Could you be a liitle more precise wiith the tools not working? I dont get any issues here like that. What hardware and OS version are you using?
Crash log can be senrt to me at the email in the readme.
Cheers

Hi,I need more time to try again problem with tools but Its easy to reproduce the crash:
Start MS2. Open new, empty project. Try to close first one (empty) which was automatically created after start.

Ta. That doesn't happen here on a SAM460, but the trace is v useful. I'll have a look at the weekend.
