Custom SVG shapes uncaught exception [message #1755487]

Fri, 03 March 2017 12:22

Eclipse User

Hi,

I am trying to create custom SVG shapes on a Papyrus profile following the video tutorial on Papyrus youtube channel (sorry but I can't send the link; no idea why).

I have associated an SVG shape with each stereotype in my profile. When I apply the profile to a new Papyrus model I get an error "Uncaught exception in transaction pre-commit task" caused by the org.eclipse.papyrus.infra.core plugin.

Here is the stack trace:

Any thoughts why this is happening? Am I missing something or is it a Papyrus bug?

Thanks,

Hi Simos,

Can you share the problematic svg?

I looked in the code and papyrus is calling the SVGLength.getValue()
The NPE seems to come from the batik library, which probably can't correctly parse your svg.

You may try 2 things:
- use a more recent version of batik (hopping they fixed that)
- fix your svg (something seems wrong in the lenght value)

Regards,
Benoît

Hi guys,

it seems I'm facing a similar issue. I tried to reference the SVG via Profile (UML>icon>kind=shape & location=platform: \resource\...) as well as by CSS reference (svgFile:"platform:/resource/..). Both shows the subsequent phenomena:

- the SVG first shows up after moving the UML element or a refresh of the entire diagram
- each refresh of the diagram throws the error below (independant if it shows the shape correctly or not)
- I've created different SVG with differnt tools (Visio, inkscape, MS Picuture Manager)
- depending on the SVG some are rendered correctly some are destroyed

So I don't think the SVG itself is the issue - but you never know. I've attached two SVG for testing.

Is there any workarround to show a shape graphic? I would be happy with a fixed size. I tried PNG & JPG via UML profile property. I can see the graphic in the small preview but it does not show up when I use it in the model. Is there maybe a CSS command to make it visible?

I was able to make it work for icons referenced via UML profile property (UML>icon>kind=icon & location=platform: \resource\...). The 16/16px PNG are properly shown in the model tree. With CSS command "displayIcon:true;" it also shows up in the name compartment.

Regards
Bernd

Hi all,

I'm facing a quite similar problem. Basically my Papyrus 2.02 is able to render SVG specified within my SysML profile for shapes. Unfortunately each rendering action of stereotype application within my model throws exeptions (see below). It does make no difference a if I reference the SVG via:

a) Stereotype properties > Icon > Add
Kind=Shape
Location=platform:/resource/..

b) CSS
[appliedStereotypes~="MyStereotype"]{
svgFile:"platform:/resource/..";
}

I'm not convinced, that a corrupted SVG is the root cause. To verfy this if tried SVG creation with Visio, MS Picture Manager & Inkscape. Attached you find 3 files.

I also tried to use non-resizeable formats (PNG, JPG) for the shapes instead - as I did for the icons. This formats are not rendered in my model at all. I would be happy with that solution until the SVG issue is solved. Do I need a special CSS command to make pixel formats visible on shapes?

Hi,

I face a similar problem. I created my SVGs using Inkscape. I attach 6 symbols in the GSN_Shapes.rar. What I identified with these symbols in *my custom diagram* is that the exception is thrown when the 2nd shape is added. For the first it works fine (no matter which symbol I will pick).

I also attach the shape Simos Gerasimou refers to in his original post, named ring.svg

Hi,

I gave the ring.svg a quick try. It does not throw any exception. Ok, we are coming closer. Anyone an idea how to create "propper" SVG?

I believe it's definitely the SVG files that are wrong because in my implementation if I use SVG files that I borrowed from another project (Archimate for Papyrus [1]) then I got no exception without changing anything else. It would be good to have a justificiation on why some SVGs fail and some do not.

I totally agree. We need to know how to generate clean SVG. And I would be very grateful to not do this by coding them.

Until that stage, does anyone can explain how to work with pixel formats in between?

To generate a clean SVG use Inkscape. this tool has gott a menu in order to clean SVG file.

Hi Patrick,
this isn't working for me. I'm using in Inkscape 0.92. I gave it a try for a circle & a square. After creation of the form I used the option File>Clean Document. Still errors with that graphics Sad

I will try to take time to see that. I hope for this week.

I've also tried saving the SVGs as Plain SVGs in Inkscape but the problem still exists.

I think that I have found the solution. When one creates a SVG (using Inkscape at least) inskcape adds the following regarding its width and height:

 width="430.28571mm"
height="258.85715mm"

The "mm" refers to the units that the size is calculated (millimeters in this example). It can also be pt, cm, px and many more. When you set the size in px (pixels) then Papyrus stops complaining (at least in my implementation).

What did I do to "fix" my shapes:
1) Open the SVG shape using Inkscape
2) Open the Document Properties window (either File->Document Properties or Ctr+Shift+D in Windows).
3) Select px in the units (see screenshot below)
4) Click the button "Resize page to drawing or selection"

This will resize your canvas to the size of the SVG (as you have most probably been doing previously) but this time the measurement unit will be set to px. If you save your SVG and open it as SVG file you will notice that the width and height are now expressed as floats without any string value to denote the measurement unit. Hopefully, this will fix your shapes as it did for me. Please let me know.
