Dia grid snapping

2013-06-23 Thread Dumitru Ursu

Hello,
I'm doing some UML diagrams in Dia, and while I'm very satisfied with 
the program itself,

I've runned into some issues.
The thing is, it's very hard to draw "straight" diagrams. I use grid 
snapping, but the diagram looks like hell.
Then I disable grid snapping, and I can come pretty close to what I 
need, but it's far from perfect.

http://storage8.static.itmages.com/i/13/0622/h_1371917042_8552590_2c8f9d65f8.png

One more thing is very annoying: object snapping. It doesn't work as 
supposed, it's very tricky to make

an arrow to snap in the place I want.

Since I'm writing this email (I'm so tired, it took some effort), I want 
to give an an improvement advice.

I used for some time yed Graph. It's a very interesting program
with some drawbacks - it's not free (as in freedom) an will never be , I 
sent an email.

- it's written in java

What is good in it, is the way you draw lines (usually arrows) - you 
drag on one object - then on the second
one you stop, and it will find the best route (avoiding crossing other 
objects).
2'nd use-case - you drag on the object, you click anywhere on canvas and 
it makes a corner, click on the canvas as much as you like, making 
corners, and the click on the second object. The path is there, fast and 
on the route of your choise.
3'rd use-case - you drag on the object, then stop dragging while on the 
same object, and it will make a loop. (very useful in flowcharting)

It would be cool to have a feature like this in Dia. It makes you 
ultra-fast.

Thank you,

Changing styles on selected objects

2014-01-18 Thread Dumitru Ursu

Hello,
My name is Dumitru Ursu, I'm a Computer Science student from Republic of 
Moldova.
I'm using Dia to make the UML diagrams for my thesis project. It works 
nicely, it's much more stable than Umbrello (although that on got better 
too),
and it has more features. One feature that I was interested in was EPS 
export, which doesn't work in Umbrello.
I also recently found about the --integrated flag, which was vital for 
me, as I'm using a tilling WM, and having a lot of windows floating 
around is annoying.


I've run into a into an issue, and I'm not sure whether is a bug or feature:
Steps to reproduce:
1. Open Dia
2. Switch to UML diagrams
3. Add 2 class diagrams on the canvas
3. Change the text color of one of them, from the styles tab
4. Select both diagrams, duble click them
5.  Try to change the color of text. Click "Apply" or "Ok"
6.  The new color is not applied to the diagram with the changed styles.

If you modify the text color of both, neither will change the colors 
when trying to do a "mass" color change.

Is this the expected behavior?
I'm running Dia complied from git.

Dumitru.

Tested in master: Pango text rendering is broken again. I don't know if
it's Dia or Pango's fault. All letters of each word overlap in a single

Except that this time switching fonts doesn't make a difference.

Then again I tested it in 0.97.2 and it's broken too. :-/ This is a show

I have experience with writing tests for web applications (Ruby on

Also, is there a list with easier issues to work on, in order to get to 
know the code base?
I searched through Dia's bugzilla, but many are unconfirmed, many have 
patches (but are not closed for some reason), and is hard for me to pick 
something.

For the issue at hand it might be useful to write a minimal but 
complete test program to show the Pango or cairo bug. It would either 
help the library developers to identify their bug or help the 
application developer to find a  work around.


I can reproduce the bug, when exporting to cairo PNG. All characters 
positions are messed up. I just compiled the master.

cairo 1.12.16-1
pango 1.36.1-1
I exported to EPS with Pango fonts, and it was ok, also as PDF with Cairo.
I will try to investigate further.

The last commit in git is from 2 days ago. Mostly translations, but also

Shoud have changed the title to " Commandline export not working for

the commit message of 
https://git.gnome.org/browse/dia/commit/?id=c3dcf1eec1b4ef57c45c58410048b77c83ea50dd


The pixbuf export requires a diaplay. Use gtk_init_check() to allow 
command line export from an X terminal without sacrificing the command 
line mode without X11.


Do you say it does not work in that margin for you?


Aha. On my computer it didn't work form xterm, on a X11 environment: if 
that's the expected behavior, so be it.




These are the bugs that I could test. The rest are Windows/Mac 
related, and

I haven't used for several years such machine.

E.g. https://bugzilla.gnome.org/show_bug.cgi?id=683700 should be 
reproduceable on Linux as well. The OS field is initialized by the 
reporter (or machine setting). Often I'm setting it during analysis to 
All if the bug is cross platform.
But even if the bug is reproduceable only on one platform the fix for 
it could potentially introcude cross platform bugs;)

I doubt you want to supply Dia along with your chart...
Either you picked a wrong tool for the job, or you should rethink your
expectations and adapt to the desired result with the tool on hand in mind.
I agree with Andrey, you are probably using the wrong tool for the job: 
I suppose what you need is Inkscape, a vector graphics program: you can 
slice the svg and make a web page out of it, or animate the SVG directly 
(Inkscape doesn't support that directly). A bit of Javascript would do 
what you need.

Also, consider Synfig as a tool for animations.

For anyone else having troubles with this, the solution is to go to File

The red grid is the one who marks the page border.

Also, as a note for developers: can't the infinite canvas be made 
optional? Having one A4 sheet by default is the way people are acustomed 
to work.
Or maybe some watermarking at each grid intersection: 600x800px>

Well I for one have (more than once) said that I'd like it to be much

Surely the usual way most people thank about a 'picture of something'
is one that can be presented fairly sensibly on a sheet of paper.
Creating a huge diagram and printing bits of it seems an rather odd
way of going about things.

Also, the 'big diagram printed in separate bits' doesn't produce
something that's easy to bind into a document.  What one wants is
*separate*  diagrams with annotated interconnections, lines simply
going off the edge to somewhere on another page are not really very
helpful.
Yup, it's a user experience problem. I think fexibility is what 
developers had in mind, and I agree that a good
program should allow for flexible workflows, and advanced features: but 
the defaults should be sensible, oriented towards
common use-cases (one could argue what a common use case is, but that's 
not that hard to find out, with a poll or something)
