Re: Dia development info

[Alejandro Imass]

The move to GTK3 and general modernization is a good idea, BUT...

Is it too crazy to take the core values of DIA and think about a
collaborative and/or Web-based version? Lucidcharts is very rapidly
spreading and there doesn't seem to be an open source of free software
alternative. An Open Source collaborative diagraming tool that could also
produce code (like dia2code) I think would be a way to revive this. If not
a pure-web version, at least think about the way Apple Productivity tools
have done it: native apps, that allow real-time collaboration AND also
provides a Web component for people that are non-Mac users.

For mainstream use, collaboration and the seamless integration with other
widely used tools such as Attlasian Confluence is essential. The concept of
stand-alone desktop tools is rapidly fading, at least IMHO.

Best,
Alex

Re: Dia does not start under MacOS 10.14.2 (Mojave)

[Alejandro Imass]

I just use the standard MacPorts version and start XQuartz first, open an
xterm and type dia from the command line. Works every time, on every
version of Mac since I started using Mac back in 2011 and I use DIA every
day.

Hi Stefan,

I would advise you to take a look at the source code for dia2code original
C code (not the new C++ port), especially at the logic for SQL DDL
generation. It will show you how to traverse a class diagram with
associations and you can probably extrapolate that to your needs with state
machines. Moreover, the dia2code C code already has some routines that are
common amongst the different code generation options.

One interesting feature you will notice is that objects are traversed first
and then the associations on a second round for ALTER statements. It’s a
practical solution which does not require to figure out the associations
beforehand. One unintended feature of this which I think you will find
interesting (and that we use extensively) is splitting the class diagram
into different DIA files. So for example if we have a 400 table database,
we can split the diagram into “realms” of tables. By putting an empty class
(just the class name with no attributes) we can “connect” to the actual
class defined in another diagram, because the generator will not generate
DDL code for the empty class but will pick up the association, thus
generating the foreign key. I noticed this “ feature” whilst I was
contributing to some patches to the SQL DDL part of the dia2code project.

May I suggest that instead of starting off a new project, that you reach
out to the dia2code guys and contribute to that project instead.

Best,
Alex

Right now DIA has the ability to create information from a diagram. Imagine
the opposite: take information and make a diagram and/or animate a diagram.

Some time ago I built a POC using SVG to demonstrate how easy it was to
build SCADA type screens by animating SVG produced from Inkscape. It was
just a POC and not too practical but proved a point of how JS was already
(back in 2012 or so) to manipulate SVG on the Web.

Imagine DIA for making IoT dashboards, SCADA screens, etc. whether it's an
output format that can be easily manipulated (e.g. SVG) or maybe through an
engine/API. In other words, change a property of an object and see how the
drawing changes. Example: a tank object has a level property from 0 to 100
that animates the liquid level.

Anyway, I think we can all agree that DIA is much more than a drawing tool.
The concept that the templates can produce structured objects with named
properties is probably the most important aspect of this software. We use
it extensively for UML to SQL DDL but I can think of so many other
applications

That's fine. My idea was just to stir things up a little and see what would
come out of this discussion.

I think the main objective is saving DIA from being shunt out of the Linux
distros and see how to maintain the Windows and Mac binaries.

BTW, IIRC Steffen's widow received some revenue from the
http://dia-installer.de/ Website so I think that even if Gnome takes over
the maintenance of the Windows and Mac binaries somehow, perhaps they could
still be distributed through http://dia-installer.de/ in coordination with
her, in respect to Steffen all the years of effort that he put into
maintaining these binaries all by himself.

Best,
Alex

What I was thinking is that we could channel some funds to a University and
have them work on it. My native country (Venezuela) is in pretty bad shape
but top-notch Universities are still operating despite the crisis. This
would be a win-win IMHO.

For sure not right now, and it's quite obvious to me that a straight GTK 3
upgrade is the logical next step for DIA. But if we work towards the goal
of at least foreseeing that additional UIs to be able to bolt-on, then I
think it would be great for DIA. Especially a web-based version that
competes with draw.io.

No reason at all. Just thought that since the effort is relatively big to
modernize DIA to GTK 3 it would be worthwhile to at least discuss it.
Moreover, I think a future Web-based interface to DIA (even if not the
primary/native one) will be important for the long-term survival of DIA
from a product standpoint.

Thanks for the insight and it's a good benchmark to compare to.

But that doesn't mean that a stand-alone App developed with Chromium and
Node.js would perform any worse and require that much more resources.

For example the Atom editor uses around 100 MB of RAM on my Mac.

Well, actually I did suggest that, at least that we discuss the different
options and listen to the users to where they want this product to go next.

My comments are just general and I haven't honestly looked into the
technical details and up to this point.

You seem to know exactly what needs to be done to get through the GTK 2
bump, and it awesome that at least someone does and understands the urgency
to AT LEAST bump it up to GTK 3. We use DIA on daily basis and don't want
to see it die. So we could cough up some cash and finance some of this
effort.

In your opinion is is too crazy to suggest separating the UI/UX from the
logic and salvaging the C code, templates and all the other non-UI stuff
 as a "backend".

For reference. One day, in the very near future we may wake up and find DIA
has been removed from Linux distros altogether:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=885686

"As announced [1], we do not intend to release Debian 10 "Buster" with the
old libgnome (and related) libraries. These libraries have been deprecated
and unmaintained for several years."

So it's not an academic discussion. DIA as it stands is really on it's way
out but no one seems to understand the severity of no releases since 2010.

Also, you are forgetting the Mac binaries. Although the MacPorts version
works flawlessly at least up to High Sierra. Not sure who maintains the
MacPorts version but it could be derived from the FreeBSD ports (not sure),
and these distros are compiled so they are generally easier to maintain
that installable binaries.

Linux versions would be generally no-issue since they are mostly maintained
by the two main distribution sources: RPM and DEB.

Disagree. I don't think that maintaining the Windows and Mac binaries
solves the underlying problem here. Maintaining those binaries is probably
very tedious and people will avoid this like the plague. Precisely the
problem is aging technology (e.g. GTK2) that may eventually prove
impossible to maintain.

So why not think in this direction or node-gtk or something along these
lines and get some fresh blood in here.

Yeah these things are important. But there are other problems. For example,
GTK2 is completely obsolete. GTK 3 was released in 2011. I mean, seriously?
The port to GTK3 is probably not straightforward (and never mind 4 which
should be quickly approaching) , so again, IMHO it would be a good time to
re-think where people want to take this project.

I have heard of people suggesting to use JSX for GTK 4, so not sure why the
"shit" comment about React earlier. In fact, React would probably be the
best bet of survival or rebirth for DIA. But heck what do I know, right ?

The main advantage for DIA IMHO is being able to integrate the drawing into
another workflow. For example UML Class diagrams into SQL DDL or imagine
Ladder Diagram to IEC 61131. If the purpose is just to vector-draw with
templates, then DIA has little hope for the future. IMO it must focus on
the ability to turn the diagram objects into other information and provide
APIs to this. That is why I’m suggesting a complete revision on both the
purpose and the architecture.

React is not “ fancy shit” but a way to write JS that can create complex
and maintainable apps. Why JavaScript? Well the reasons are obvious, and of
course it could work “off-line”. But better than that is that it would be
truly universal and run in any JS container. The back-end should be clean
and portable, and perhaps it could also be JS. The idea of the back-end is
to provide a consistent API into the information contained in the diagrams
and integrate those diagrams into a live system. Imagine for example an IoT
dashboard built with DIA.

Lastly, XML May be a strong foundation but it’s quickly becoming obsolete.
Besides, if DIA was so XML formal it should have had formal XSDs and things
like dia2code should have used XSLT a long time ago, but all of those
technologies are quickly fading away.

Look, you can sit here and argue all you want and be blind. But the truth
is that anywhere we try to push DIA in our customer’s workflow we get
pushback and Draw.io is providing all these things and more, and it’s free.
It would be great if DIA could evolve into an OpenSource draw.io or
something even better.

Re: Maintaining / Helping out on Dia

[Alejandro Imass]

Just my $0.02 Background: I have been using DIA extensively since the 90s.
I use DIA and dia2code for UML and even do all my database modelling in DIA
with class diagrams and then create the DB models based on that. I have
even contributed to dia2code on enhancements that we've needed over the
years and we just give for free to the dia2code community.

The reality is that DIA is an amazing piece of software but it's old and
the diagrams it produces are ugly. I know this doesn't sound very technical
but people love eye candy and DIA has been falling short on this for a
while now.

IMHO maybe a fork is required to take DIA to the next level and separate it
from GNOME even if you decide to keep using GTK and move to 3 or whatever.
More than the actual graphics library I would look into taking the things
that are really valuable from the current code and perhaps think of a
complete re-write with React, Anguar, Ember or whatever. I would get out of
XML and go to JSON and re-write the app into a React front-end with a
corresponding backend and API. IMHO the greatest long term existential
threat to DIA is not Visio or Omnigraffle, it's draw.io

Problem is "eye candy". If a project is stable and good then it's
dead. Quite the contrary, I think A LOT of people use DIA from their
Linux distros and don't even know about this list 'cause it just
works.

So sad that we have this mentality that if it's not shiny and new then
is shit or "is dead". Consumerism and Edward Louis James Bernays at
he's best.

Try document scale. Not sure if you are referring to the diagram as such or
the objects of the template sheet you are using.
For example, the UML objects do not resize either but if I want to fit more
objects per page I just change the documents scale. For UML 40% works
pretty well for most diagrams in US Letter.

Also make sure you have the latest version from Sourceforge, not the older

should redirect to the SF download site. But you still need to edit the

You get the window back through the XQuartz menu, not through OS X icons.
In other words, all X11 apps run inside the XQuartz container so to speak,
so even though the OS as such sees the process, then native OS X Windowing
system only knows about XQuartz.

We've been using DIA for many years now and wonder the same thing. Sadly we
don't have the economical resources to do it but it does need some work for
sure. I recently evaluated all the UML tools out there (and their ability
to translate diagram code into something valuable akin to dia2code) and
frankly none of them impressed us too much so we are still using DIA.
Although we are considering Astah.

DIA is really a great tool, and surprisingly stands up to most commercial
counterparts, and to me it's a shame to move away from DIA but it's also
sad to see a project with so much potential fade away or with such little
active development.

 Hello,

 I'm trying to create java code from a workflow diagram. I'll look into

 share it.


Well that sounds like a pretty wild request and I believe there must
be some misunderstanding on the requirement.

Usually you don't translate Workflow to code directly (e.g. Java) but
rather to some declarative workflow definition and is usually in one
of two forms: EPC or Petri net.

So for example you would take a UML 2 Activity Diagram (similar to a
flow chart) and translate yo some Workflow XML such as:
http://search.cpan.org/~jonasbn/Workflow-1.41/lib/Workflow.pm#SYNOPSIS

I can't speak for the Java world but there are surely some standard
off-the-shelf Workflow engines that work much the same way as the one
above. I mean it would be very hard to develop a workflow code
generator from  scratch and is not even practical or useful.

The actual (e.g. Java) code should already exist in the actions
themselves as atomic procedures that are re-used in your workflow. In
Bonita for example the action itself is usually a Groovy script or a
call to an API of some sort. Same concept here.

Just as an idea a good architecture to deploy such a Workflow in Java
would probably be OSGi, where you could have a SOA model in JVM. So
individual actions are modelled as services and the workflow just
calls these services with IN/OUT params specified in the workflow
OSGi would make it easy to add/evolve services without even restarting
the engine. Would surely beat the crap out of many commercial WF
engines I have played with.

 Dia file is a flat or GZIP'd XML file.
 Use any XML mapper you are familiar with to retrieve the information

To transform it to something else you don't need Java just use XSLT.
If you are generating SQL or some other case-style application don't

Hi Paul,

Which version of dia2code are you using? There is a dia2code list IIRC
and I made some patches to the SQL module some time ago. But there was
a bit of a glitch between 0.8.4 and 0.8.5 which I have never come
round to fix but is a perfect time for me to recheck this and also do
some work on DIA which I have put aside for far too long.

The sql converter uses the direction of the association. The pk and fk
columns need to follow the surrogate key convention where the fk
field needs to be named foo_id and always point to the pk of the other
table which must of course be named id. The name of the association is
also important. I will try to post some complex examples on the
dia2code web site. The pk is determined by setting class scope to
the pk attribute or attributes (it supports multiple attribute pk)

DIA and dia2code is REALLY powerful and we use it on a daily basis. I
have maintained complex models for Pg with hundreds of tables. Maybe
we have an old project somewhere that is no longer active and I can
publish the whole process.

Anyway, is a perfect opportunity for me to retake some of this work
and maybe fix the small issues in 0.8.5

You could try UML Class Diagrams and transform them to DDL with

Re: dia-installer.de / Steffen Macke

[Alejandro Imass]

Hi Felix,

Whilst not an expert I can surely get up to speed with the Mac
distribution, not the Windows one though.

Let me know if nobody else offers to maintain the Mac installer and I will
pick it up.

Best,
Alejandro Imass

 hello dia developers and users,

 as you may have read in a previous post, Steffen has died last year.
 Steffen maintained dia-installer.de which consists mostly of:
 - a windows installer (including dia portable)
 - a mac installer
 - Debian and openSUSE packages
 - dia shapes repository + installer
 - documentation
 - ...

 His wife, Yasemin, told me that she has administration rights for
 dia-installer.de (and most probably also access to his source codes).

 It would be great (and probably satifying for Yasemin and Steffen's
 familiy/friends) if someone could pick up things like the windows/mac
 installers (maybe by Windows/Mac experts who also use dia) or other
 parts like the shape collections or keep dia-installer.de running or ...

 Unfortunately I cannot do this, as I work on Freeplane, Debian and
 GTypist already and am running almost exlusively Linux.

 The good news is that some of his probjects are available as
 official Debian packages:
   https://packages.debian.org/sid/dia-shapes
   https://packages.debian.org/sid/dia2code (not from Steffen himself I
   think)

You would get better answers if you ask a better question, please see:
http://catb.org/~esr/faqs/smart-questions.html

How is your Mac model relevant to solving the software problem? What is
your OS X version? Did you really search the archives lately? Your
reference is from 2010!! and this topic has come up several times just in
the past month. Here is a solution I posted just a couple of weeks ago:

https://mail.gnome.org/archives/dia-list/2014-November/msg00032.html

Also, FYI the maintainer of the OS X binary distribution (
http://dia-installer.de) apparently died recently, rest his soul,  so
unless you want to take over it is unlikely it will be fixed any time soon.

You can use the MacPorts or Homebrew versions and they should work just
fine.



 How do I fix this so I can get some work done today?


Use MacPorts or Home brew and forget about binary distributions of Open
Source in general. Especially if you are using a Mac.

This DIA binary for Windows and OS X is maintained by
http://dia-installer.de

I have written the maintainer of this package 2 times w/o response, yet.

You can download and build latest DIA via Macports without deleting your
previous dia-installer.de binary and then perform this trick to keep
launching from icon. This procedure will emulate the binary package which
runs integrated window, etc. Anyway, this works for me until maintainer
decides to publish new package for Yosemite, or you can keep using the
MacPorts version this way for ever.

 Hi Dia team!



 You guys have done a wonderful job just making it really simple.  The last

There is a common misconception that putting out new versions regularly
gives some sort of reassurance that the product is alive and well. This is
somewhat true with proprietary/commercial software as new versions usually
mean active development and staying ahead of competition. In the open
source world it is usually quite the opposite. There is no need to put out
new versions to stay ahead and new versions are the product of small
contributions that eventually find their way to a new version.

If you like the software and it gives something to you, then you could also
give back by contributing in any way you can and help drive new versions:

 I achieve this functionality by selecting the desired object/group and

 desired file type, load the png or pdf file into the other app and discard
 the temporary document.

 An export selection option in the save as dialogue would be of great
 conveinience in this regard.


Yeah I think that's what the OP wants to avoid. In any case you are correct
and it would need to be something like export [to clipboard if they want to
avoid the intermediate file].

One way to accomplish this is to just add a trigger to save and process
the DIA file (which is just zipped XML) with an XSL transform into some
temp file and pick it up from there. DIA also works with a de-compressed
version of the DIA file and we use this for source control of what has
changed in a diagram. One of the actual most valuable features of DIA is
the structured objects that can be transformed into other things with tools
like dia2code. But you don't really need dia2code because any XML/XSL
programmer can easily do a lot of magic with just XSL and a some generic
parser like Jame's Clark XP or libxml2.

Another option would be to extend export into something like export to
clipboard in some known exchange format for that platform (Windows Enhance
Metafile?). Maybe GTK2 has some features/facilities to interact Win
clipboard.

I c what you're saying.

Yeah, Inkscape has that feature and is really useful. I find myself
creating one small DIA diagram per figure for a doc whereas with this
feature you could have a single diagram with all the figures and then just
export selection the individual targets in whatever format. A simple
checkbox/dropdown saying export to clipboard would kill 2 birds with one
stone.

For the OP's requirement I think they would also need to add export to WMF
and they would be done. Pretty sure the GTK clipboard can interoperate with
Windows clipboard but not sure how. I wonder if the current Windows port
deals with this.

  Alex,

 Very good advice on the 40%.  I tried that but for my multi-page diagram,
 Dia still printed the same 6 pages to pdf with the 40% part at the upper
 left of each page.


That's odd. Can you post (or privately send me) an example? What OS and DIA
version are you using?

We have been using multi-page diagrams for years, first in Linux and lately
on OS X. We use landscape mode and the printing is so good it actually
allows to tape large models together. Printing starts at top left sheet and
moves to the pages on the right, then row by row, so our diagrams usually
start on 0,0 and we grow them down and right from there.


 So I tried importing the svg into Inkscape set to cm, but it then printed
 the text at 1/16 instead of 1/8 (Inkscape does not do well with
 measurements!).  So just exporting an svg and shrinking it will be the way
 to go, as you say.


As with any tool you need to figure out if DIA is the right tool for you.
It's not a CAD tool for precision but it's an awesome modelling tool. For
example we model in UML class diagrams and then export the DDL using
dia2code. You can parse the DIA XML with basically any tool perhaps even
with XSL and a standard XML parser.


 What I'm after mostly is nice svg files for the web anyway. Printing will
 work itself out :-).


If you are looking for a generic CAD-style SVG editor perhaps Inkscape is
better suited or maybe even a combination of both tools.

Alex

 As I make my shapes, I would want to make them so they fit 9 pt font size
 (1/8 tall), which is what I consider to be the perfect size (so studies
 say for us CAD users), and the borders would be 0.5 mm thick instead of
 0.1cm.  This means I would make much smaller shapes.  Would anyone be able
 to use those shapes, or want to?



Just scale the page to whatever you want I use around 40% for UML diagrams
and works pretty well but YMMV

DIA is probably as intuitive as any other diagraming tool like Visio
or Omnigraffle and nothing in DIA can cause it to uninstall all of
your programs.  So I'm guessing you probably downloaded some malware
posing as DIA, or your operating system is broken, or your machines
is infected with some virus or other software that caused this
behaviour. DIA is downloaded and used on a daily basis by hundreds of
thousands of people around the globe and has been around for many
years. If you came here seeking answers you should specify your
operating system and version and where you downloaded your DIA package
and the steps you took that caused this problem. Ranting out against a
community of volunteers that provides such great software for free is
not the smartest or productive move. I for one have used DIA for more
than a decade and for the past 7 years I use it to model complex UML
Class Diagrams that convert automatically to SQL DDL. So please don't
come here bashing out something that is really practical, works just
fine and open and free.

Hi Gene,

Perhaps you should start by explaining what you're trying to do. If
your expectation is schematic diagram drawings Dia (or Visio) are not
the best tools for that. Dia is a general purpose diagraming tool, as
in not specialized. If your expectation is ladder for example, then
DIA might fit the bill but there's also some open source IEC 61131

 This is not the same thing. Printing a file to PDF makes the content

 If it is already a feature and it is not present in Fedora 19, what should I

You did not state up to this point that this particular feature was
not present in your Fedora version. I told you specifically that you
should have the Cairo option and you never answered saying it was not
available to you or not.

Since you mentioned Latex later on one of your answers I believe there
are far better options to embed your images in a Latex document than
using  embedded PDF. That is exactly what EPS (if you want to maintain
vector), SVG, PNG and other more embedded formats are for. Using PDF
is not the most optimal way because PDF was designed for another
purpose, namely printing much like plain'ol PostScript.

PDF and PS __are not__ graphics file formats and should not be used
for embedding because their are targeted to a page, not a predictable
bounding box. EPS is exactly designed for this task[1], but most Latex
nowadays will support PNG and many other graphics formats. PDF is
actually the worst choice for this task because Each PDF file
encapsulates a complete description of a fixed-layout flat document,
including the text, fonts, graphics, and other information needed to
display it.[2]

Nevertheless if you are using pdflatex (which you don't mention
either) it does not support EPS which is actually very stupid IMHO,
but teTeX distribution includes a tool, epstopdf, to convert EPS files
to PDF. pdflatex notwithstanding does support JPEG and PNG directly,
but scaling, anti-aliasing and choice of export font requires some
additional effort to get right.

You can also use EPS directly in your LaTex doc by following by using
DeclareGraphicsRule much like the recipe here:

 Excellent question. I don't know of one and would probably be hard to

 You're confusing structure with functionality.
 XML Schema describing the document structure, not document contents.
 UML, and whatever else, is part of the same structure.


Hi Andrey,

I phrased it wrong. The structure is actually pretty basic but depends
so much on the type of object (UML, etc.) that a schema would be of
little use to extract or transform to anything useful without knowing
how the module implements the structure. That's what I was referring
to, not that an XSD itself would be hard to manage.

Don't give it too much though and just dive in and get what you need
for your particular scenario. We transform DIA and use it natively in
our software development process. For example we use dia2code to
transform class models to DDL and we also extract info from the dia
file itself to create Docbook tables to document the data dictionary,
and some other uses as well.

What are you trying to do?

 From: Alejandro Imass aim...@yabarana.com


 What exactly are you missing for UML 2? We use the UML 2 standard with
 DIA (albeit not religiously a la OMG/Rational) but we are very fluent
 in V2 and we use DIA for all our work. Can you provide an example of
 what you are trying to do?


 Alejandro: a fair question. Unfortunately this was a bit of a
 'fire-and-forget' post, as the UML modelling work I did that brought up some
 apparent shortcomings was quite a long time ago. I'm in the middle of some
 other work and don't have time to go back over it (I'm not even sure which
 particular diagram types I had frustrations with), but I appreciate that I
 probably can't expect too much help without more details!

 I may also not have 'thought laterally' enough in terms of adapting existing
 shapes for my needs.

 If/when I have time, I'll go back through everything and post again. Out of
 interest, what are the normal set of diagram types you use and where (if at
 all) do you need to use shapes outside the UML set? (I know that, in
 principle in UML 2, these are not rigid divisions...)



We are not UML experts by any means, being a small and dynamic shop so
we only use about 5/6 artifacts in most of our work:

1) Use Cases: extensively used during requirements phases and also
internally to discuss scope, etc.
2) Activity Diagrams: for business process definitions, specifications
and also scoping.
3) Communication Diagrams (prev known as Collaboration Diagrams in UML
1): we use these extensively for design, to count components,
packaging work and planning. Perhaps we abuse Communication Diagrams
because we are probably combining Object and Component in a
behavioural view but they have been very useful for us since UML 1.
They are easy to understand by everyone so we bend the rules here.
Besides, we use UML as a guideline not as religion.
4) Class Diagrams: we use these twofold. Sometimes for software design
or to emphasize some particular design feature, though not common
because we program full iterative + TDD so class design is mostly on
the fly. However, we do use Class Diagrams extensively in database
design and we create the SQL-DDL scripts directly from the diagrams
using dia2code. This also allows to document any triggers as methods
on the tables though it's only informational. All comments on
properties are used to automatically create the data dictionaries for
documentation simply with an XLS sheet that extracts this info from
the DIA file.
5) OSD: Only in cases where timings are really important we use OSD.
6) Package Diagrams: we have used them but usually #3 above does the
job for most of the development we do.

I have used DIA since about 1998 with UML 1 and then switched to UML2
style probably around 2010. Actually it's a funny story because we
wouldn't have changed anything if it wasn't for a customer who
happened to be a university professor and rejected all our documents
because they were all wrong. We were in fact somewhat updated to UML
1.4-1.5 at the time, but he forced us to adapt to UML 2 so we forced
to catch up. In reality though, our problems had nothing to do with
UML versions but rather was abuse of use cases (as we would violate
the requirement - design frontier) and that we didn't use Activity
Diagrams at all, things we could have corrected using UML 1, but we
had already read-up on the new stuff so we upgraded.

For our work the impact was very low and we found no limitations with
DIA to keep up with the new UML 2 styles. If you do find them, let's
discuss theme here and see if we can contribute together to solve
them.

Dia runs on many platforms. Printing is one of those things that is

 I have a trouble. I'm trying to do a UML diagram, which has a class that

 and I need to know: Is there any way to keep all these lines attached to the
 class?, or I can only attach lines to the points specified in the rectangle?


Yep, you can only connect to the connection points on the classes. On
some element you can add extra connection points (e.g. the basic line
primitive) but not on the UML class. Tip: the UML class will create a
new connection point on each side for each attribute or method.

If you are going to post-process your diagrams, say for example to
create SQL DDL from UML classes using dia2code then you must take care
of creating correct associations so the foreign keys and indexes
generate correctly. Note that FK relationships are akin to UML
associations not aggregations or compositions.

I think you are referring to the page scale factor:

File-Page Setup

Look at scale and fit-to sizes. If you want your objects to fit in one
page you can use fit-to 1 by 1 or play with the scale factor until you
get a satisfactory fit in the pages you want. I typically use a scale
factor of between 20 and 40 for the UML sheet but of course YMMV.

It could be a simple refresh. Try moving the screen around and see if

Hi Justin,

DIA is a great tool for making diagrams with pre-defined sheets, and
it's especially useful if you'd like to convert the drawing to
information to be used by other programs. In our company we use DIA
UML sheets and transform the diagram into information that connects
the diagrams to other parts of our development process. For example,
our UML Class Diagrams are converted to SQL DDL automatically and thus
drives our complete development model.

BUT, if you are looking to replace Corel Draw, I don't DIA will fit
the bill because it's not designed to do so. For that sort of
application I think you will have better results with InkScape:

Back in the days I used Windows I used to keep a companion PowerPoint
presentation with all the images contained in a doc. This is because
Word would sometimes freak out and lose all the images with a crossed
X and I would lose al my images. Once I lost 2 months of work and
backups did not help. With a companion presentation it is easy to
import images and then copying a slide and pasting it as a windows
metafile in Word. It works pretty well and you can keep your images
somewhat stable in one place that is NOT M$ Word.

Fortunately I haven't used Windows for many years and I now code my

For short documents and small manuals I used LibreOffice but it sucks

UML set for far too many years now ;-)

We dome some really magical stuff I would like to publish one day.
Well in fact we have, for example I made some contribs to dia2code in
the SQL DDL generation but we really have to publish this very
interesting end-to-end methodology we have with DIA. From use-case to
actual model and documentation in Docbook tied directly with the code.
Really neat. 10x better than any attempts to do the same with Rational

Re: DIA - Labeling arrows

 Hi,

 Any way to add labels to arrows in dia?  It's a pretty critical function.


I attach text labels to lines. You can connect them in the middle node. So
the procedure is this:

1) Create your line
2) Create a text object and when you finish editing you should see the
connector on the bottom left corner of the text.
3) Click on the connector (will not work if you drag the text itself, only
drag by the connector)
4) Connect the text to the middle of the line (should turn red to connect).

It's not perfect but it works for me.

 I use UML associations and messages for this. It's overkill and a bit ugly,
 but it works.


Interesting. We discovered the attaching of text labels to simple
lines because in UML use cases we needed simple straight lines, and
simple lines with labels for extends, includes, etc. We could have
used UML messages with the simple message type, but it would only
work for include, so we decided to stick with simple lines and
attached text labels because it works for all cases and gives us more
flexibility.

We've wondered why there are no connectors for use cases in the UML
sheet. Anybody know?

Michael, you are correct. My last email was incorrect, only one
connection point that can receive connection in the middle.

 But if you have a connection point the you can move that point around and
 the two lines will follow it.  Seems like the perfect solution for the
 diagram he is trying to make.

Yes. If you add a few they will get close enough to the end.


If the ends of lines can connect (i.e. are connection points
themselves) why can't they connect to each other?? it seems like

Cool feature UML and text labels

[Alejandro Imass]

Hi folks,

Just wanted to share something cool. Since AFAWK  there is no formal
connector for use cases we use ordinary lines. But for includes and
extends it had become cumbersome to move manual text labels around
with lines. Today we discovered you can actually connect a text label
to a line so the text moves when you move the line. It works quite
well for UML use cases.

Enjoy!

 A single A4-format Dia sheet only exports to about 470x300px, which is

 Is it possible to increase the exported image size?


When you export, at least to PNG you have the option to select the
image size. But you should try to export to a vector format so the
final images can scale and/or print correctly. Try EPS if you want to
embed these output images in other documents (e.g. DocBook, Libre
Office, etc.). For printing, use PS or PDF or print directly from DIA.

So when you do File-Export, choose png and click ok you don't get a

Close DIA and open it again and you should get the second dialog (PNG

What version? What OS?

 SADT/IDEF-0 diagrams. I have loaded the shape sheet SADT, but I only
 see on kind of activity flow: Vertical-Horizontal-Vertical. How do I
 make the Horizontal-Vertical-Horizontal flow arrow that will be like
 the VHV arrow? I read about deleting/adding segments, but then I can't
 figure out how to make HVH shape work like the VHV shape (greying the
 shape and arrow head) nor can I make sense of trying to get that new
 HVH shape actually saved in the SADT sheet.


1) Take the flow arrow and connect it where you want it. For example
from activity box 1 lower right connection point to activity box 2
upper left connection port. The arrow will be pointing downwards and
you will have one segment with a yellow square and the two end should
be connected by showing red squares.

2) Drag the current segment upwards by clicking on the yellow square
until it passes the top of activity box 2 (which in IDEF0 will usually
be bellow box 1). Now right click on the vertical part of the line
that is sticking out of box 2 and select add segment. A new yellow box
should appear on that vertical line, and the line should turn black
because it's now a horizontal flow.

3) Click on this new yellow box and drag it to the left. The new
segment will grow to the left and the arrow should now point correctly
to the right. To change the flow style double click on the line to
open it's properties. Don't know too much about IDEF but AFAIK
horizontal flows should always be black, and the only option (at least
in DIA's SADT/IDEF0) is to grey the vertical ones, but if you want you
can force grey the whole line by changing it's colour in the object's
properties.

 Buon giorno,

1) Dia is translated into many languages including Italian. It uses
the common gettext method and po files for this. I noticed that the
Italian po file seems quite old and it's ISO-8859-1 whereas most
others have already moved to UTF-8.

2) I'm not really sure how Dia works on specifically on Windows so
maybe some Windows expert can fill in the gaps. But I would suspect
that GTK on Windows is ported in a way to understand the current
user's regional settings and this should get Dia to work automagically
in the language that the OS is in. In other words if your Windows is
in Italian then most probably your Dia will show up in Italian as
well.

So to answer your question it may be as simple as setting your
regional settings in Windows to Italian and that should get Dia to
work in Italian. Maybe there is a way to keep your Windows in English
and to set some environment variables before launching Dia to get it
to display in Italian. This means that the language variable in your
OS has to be something like it_IT.ISO8859-1

The locale must be available and the underlying C library must see it.

As to how easy or hard is to get your Windows to work in Italian you
have to check with Microsoft.

 Hi, are the FOREIGN KEY constraints supported?


Yes, but dia2code is a separate closely related project.

Primary key: properties that are class scope. Just set it to class
scope and it will generate a foreign key. It supports multiple-col PK.

FK: Make an association from the owner of the data to the class that
uses the FK. In that direction only. Example:

Person -- Role (Role class references Person class person.id and FK
is named person_id).

1) Select the UML association tool. Click on center of Person (the
owner of the referenced key) and drag it to the center of the Role
class. Name the association person_id. The surrogate key model is
assumed so the Person table has a serial id and the Role table has
person_id.

2) The id on Person should be  class scope

3) Run dia2code -t sql -sqlx fkidx mydiagram.dia

This will generate the DEFINITION.SQL DDL for all tables. Then you
should see the alter for the primary key and and alter for the FK
something like:

ALTER TABLE role ADD
CONSTRAINT  FK_role_person  FOREIGN KEY(person_id) REFERENCES person (id);


Associations are processed last as ALTERS to avoid dependencies on
tables. So the basic DDL is done first and associations are done last.

The -sqlx fkidx will also create the indexes for the FKs.

You will need late dia2code 0.8.4 or 0.8.5

I'm guessing something is seriously broken in your particular version.
You need to specify exactly what versions you were using in RedHat and

 2) DIA automatically opens a saved file in a best fit mode. If I have a
 works in progress and want to expand the canvas, my only option is to resize
 by zooming to a smaller scale and adding the new layer. Eventually, that
 scheme will run out of steam because the objects will become too small to
 properly manipulate. I would like to see a expand canvas option which
 would retain the current zoom level, but add more canvas accessible by the
 scroll bars. Plus, one should be given the option of specifying which
 direction to expand into.


Not sure if I fully understand this particular limitation you are
referring to in point #2. Some objects are able to scale and some not
(e.g. UML) so you can just scale the page by using File-Page Setup
and look at the scale field. When you reduce it (e.g. 40) it will
allow for more non-scalable objects to fit on the sheets.

We've been using this mechanism for years and our diagrams scale quite
well by reducing the scale mentioned above.

 I want to know if I can send a copy of the diagram by email to another
 person?


 Export it to PNG (beware that there are more than one PNG export filters)
 with a fairly good resolution and attach it.


Or, a vectorial version (SVG, PS, etc.) that can scale

 That's what I do.

Re: Dia layout drawing

[Alejandro Imass]

Basically yes, but if you need a lot of precision you should evaluate
a more CAD-style solution, though Dia is pretty decent once you lear
to use it.

Open File-Page Setup

And the first thing is to decide the paper size and for your
application you probably want to select the horizontal layout as well.

Then look at the scale factor which is the scale relationship between
objects and the paper size. The smaller the scale the more objects fit
on a screen, that is, when using the object templates[1], but in your
case you need to figure out the grid scale versus the paper scale just
like using a scale rule.

[1] Some template objects seem to have a fixed relative size and grow
automagically (e.g. the UML template) while others allow for you to
scale them, so keep that in mind.

Assuming you are using USLetter horizontal, then your page will be
21.6cm 27.9cm and the default margins will be 2.54cm on each side,
which is 5.08 that is not visible on the grid. This means that the
actual grid, starting at 0,0 should go from 0 to 22.82 on the
horizontal and 0 to 16.52 on the vertical. This is for the first sheet
and the rest is a continuum so you can actually print and then tape
the sheets at the margins. Most printers will require 1 margin anyway
so the default 2.54 margin is safe.

Finally you can tweak the grid properties in File-Diagram Properties
but the dynamic grid will work well for most applications.

Best,

 I have been testing the Dia app for layout drawings such as floor plans and
 was wondering if its possible to set and display dimensions of lines as well
 as set a specified scale for the entire drawing?



 Thanks
