Loading exported SVG by Illustrator into Geomerative error: OutOfBounds: -1

in Contributed Library Questions • 3 years ago

I was having success so far, importing svg's into Processing using Geomerative, but have run aground.

RShape grp = RG.loadShape(filepath);

suddenly leads to:

processing.app.debug.RunnerException: ArrayIndexOutOfBoundsException: -1

at processing.core.PApplet.run(PApplet.java:1496)
at java.lang.Thread.run(Thread.java:637)

This only happens at one of the 6 different files that are being loaded, which all have been created by the same program, and all have been edited by Illustrator and resaved.

The funny thing is that this happened AFTER I opened a SVG that was exported by a GIS program in Illustrator, cleaned it up (removed fills) and saved it again as SVG 1.0. Before this, it loaded fine.

Previously, one of the files that came directly from the GIS program immediately throwed this exact same error, and I solved this by doing exactly the same as what now causes it: editing it in Illustrator, removing fills and resaving it.

I'm at a loss here.

So I went back to Processing's SVG implementation, but can anyone confirm the methods listed here (especially the getVertex(int) method) don't work yet?

Might it be that the problem lies with the inclusion of multiple inner shapes? I read some early versions of Candy had that problem..

hi,

could you send me the file that is failing in Geomerative? I would like to see what's wrong and try to fix it. If you cannot disclose the file for any reason you can maybe just send me a private message with it or something.

cheers

Sure, the data has been harvested from open source sources, here they are:

http://tiemen.pruts.nl/processing/svg_problems/

I exported the urban.svg from the ai (ICS4) by removing all other layers first, to make sure no hidden data makes its way into the svg. I'll include the coastline svg too (that is working) as a reference (but you can export it yourself from the ai)

Thanks btw.. I'm very impressed by the library. Why isn't it part of the Processing core code yet? You seem to have figured out everything that is listed on the PShape page..?

Ok. You can try now the latest geomerative (rev 31), this problem should have been fixed.

thanks for the testing file

Another quick question though, does your RSVG also extract the document width and height? Couldn't find it in the docs, and am currently extracting it with xml, effectively loading the file twice :/

Just curious, i was following this thread but couldnt give an answer. what was the problem ?

I was wondering that too. I remember someone having a problem where values in the SVG data were in exponential format. IIRC that involves the letter 'E' and I'm sure that was the cause of a compile error in that case...

yep, was my first thought as well... i remembered philo saying "well spotted blindfish" ;) thats how i found the threat again, hehe

Wow thanks.. A special geomerative revision, made just for me and my problems... that's cool! :)

Open source code can advance greatly thanks to user feedback!

Your problem is the problem of anybody trying to use similar files...

RSVG doesn't extract viewport information from the SVG, this is something that I still haven't figured out how to handle. Because RShape are effectively only shapes and SVG are documents with shapes in it. When Geomerative loads an SVG it's really loading all the shapes it contains and grouping them in a big group shape.

However document attributes such as width, height, viewport, etc... I wouldn't know where to put them/return them. Currently yes, you will have to load it twice.

Yep, the problem in Geomerative's SVG parser was almost this, but not exactly. Exponential numbers are correctly parsed, however when the first coordinate of a shape was negative it would fail.

The exact problem in Geomerative's code was that I was checking whether the previous character was an 'e' or 'E', and since it was the first character we would get a OutOfBounds: -1 exception.

Wow thanks.. A special geomerative revision, made just for me and my problems... that's cool! :)

And yeah! as phi.lho said that's what's great of open source code and Processing's great community. Thanks for the feedback!

Well, you have already something in place called getOrigHeight(), what hurting would there be if the RShape loadShape returns would have a getDocHeight() or getOrigDocHeight() method, which in any other case would simply return null?

Like I said before, you've done great work with this library. I love it.

Ok, I have added the .width and .height properties to the RShape where the SVG document's width and height are set.

This should work like PShape .width and .height.

Geomerative 32 is out there.

Looking forward to seeing how your project ends up looking!

Richard, rev32 suddenly gives me

RG.init(this);

Cannot find anything named "RG"

Running any example included in the zip.

?

Hmm... it seems to work just fine here.

Maybe there is a problem with the installation. Be sure you remove old versions of the geomerative library and that it is in a place that processing can find it.

/your_sketchbook_path/libraries/geomerative/library/geomerative.jar

And finally make sure to relaunch Processing after installing the lib.

hope it helps,
