[Plugin] ImageTrimmer

TIG

thanks for the quick reply,
the "EdgeDetector.jar" file has already the correct Properties.
There is an application called Java-preferences in the utilities folder, but I am nut sure which settings I should change.
It has Settings for Security, Network and - I'm trying to translate since my OS is in German - two options for:
"Run applets" > 1) "within own Process" or 2) "within browser process"
Does that have any relevance?

I don't know.
Try using alternatives and retry 'ImageTrimmer' for each.
If it works one one thane that's the setting you need
If you do find the fix I'd appreciate it if you posted the settings as a few other MAC users seem to have issues too - although many don't

Thank you,

I am fiddling with the settings already, with no luck so far.
I did a quick google search for "setting java permissions osx" and that opens up a whole new scary landscape for me, which I am not sure I should embark upon right now.

TIG

If there are any MAC users out there successfully using ImageTrimmer then please contribute your settings etc so that other MAC users can benefit too...

Hi again TIG,
The problem persists, it appears the same Console Error:

Console error

The EdgeDetector.jar file goes if you double-click on it, the permissions are correct, i think the problem on mac is that the plugin don't access to the EdgeDetector.jar file, i can't say you more.

TIG

Thanks Oxer... I've got some other MAC users [via PM] investigating the issue... watch this space...

The banana_tree at that size has ~3.5 million pixels that would need processing into viable edges !
At 1/2 the size [scaled in Gimp] it's 1/4 of the pixels and although it's still too many to be sensible it probably won't splat - but it just doesn't do miracles, it just takes time... !
You have a lot of semi-transparent bleeding edges that also up the processing time dramatically - edit those out too - they're probably the biggest processing time killer, as it might have to find all sorts of small loops from the small semi-transparent 'islands' before discarding them.
You also have a lot of other small areas of pixels that will be ignored as edges as they are too thin [<2px] BUT these still need to be examined which slows things down too - so pre-edit the image a bit to simplify it!
[but you probably need 3Gb+ RAM too!]
Here's a result at about 1/2 size - original image, then as trimmed unsimplified and simplified x2.0...banana_tree.skp

Thank you very much for heads up and for a nice plugin !!

Here's v2.2 http://forums.sketchucation.com/viewtopic.php?p=294815#p294815 - follow the links to the 'download' page in SKMtools......
The MAC jar file execution has at last been addressed
[My thanks to Dave R for helping with the MAC testing etc ]
On a MAC you might find you are asked if you want to run a particular jar file - if so answer 'yes' - it's a one off prompt per jar-type so it should stop after the first run.

Feedback please...

Flawless !!!
It now runs without Interruptions. Prefect results - especially with the ImageTrimmer-Simplifier afterwards.
Thanks a lot TIG et al !
If it is not too complicated I would be interested, what the problem was running the scripts on the mac.
Thanks again

It was a bit obscure!
The command UI.openURL('file:/'+path_to_jar) works fine on all PCs AND on MACs where the path doesn't start with a '/' - e.g. PC's 'C:/Program.../...'.
BUT some MAC users install their Plugins in an alternative location which starts with a '/' therefore 'file:/'+path_to_jar fails as it doubles up the '/' to '//' and the file isn't then 'found'

So I added an additional test: if ' path_to_jar' starts with a '/' then jar='file:'+path_to_jar else jar='file:/'+path_to_jar.

So in the end a simple problem was masked by lots of other issues - but at least it's fixed [at last]
[Actually Oxer HAD spotted the nature of the problem a few weeks ago, BUT "the penny hadn't dropped"... ]

Hi TIG,
Finally the problem have been resolved, sometimes you have the solution in front to your eyes but the forest don't let you see it.
Thanks TIG for you perseverance.

TIG,
on a MAC, the pathname always starts with a '/' because that's the root directory. Volumes follow behind that slash.
Oxer stated two alternative Pathnames on his Mac earlier in this thread, the second of which started with "Library/...".
It should really read "**/**Library/...".
Hope I don't come across as beeing pedantic; maybe it helps avoiding similar problems in the future.

OK - but it works now as the PC and MAC versions are differentiated by the inclusion or not of a trailing '/' after 'file:'

krath

Yes, it does!
Thanks to your persistence in solving the problem.

Heather hasn't tried the 'TIG PLAN' diet and comes in at >200% heftier...

finally I got it to work on 10.5.8, and just incase it saves others some time searching.

if you have them put them in this order, else download so you can.

Hi TIG

I have migrated my version of skp to a new pc running windows 7 (former pc running winxp) and my image trimmer is not working at all.

The tool does appear to start to run on an imported png file (as image) but won't progress to the first prompt to stand up the component etc. It simply stops and allows you to go back to using the skp tools.

Ruby console report is below:

Error: #<Errno::ENOENT: No such file or directory - C:\Users\Apache\Documents\TrimmedImages\Untitled-1[Edges].dat>
C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/SKMtools/ImageTrimmer.rb:232:in readlines' C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/SKMtools/ImageTrimmer.rb:232:in make_edges'
C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/SKMtools/ImageTrimmer.rb:185:in process_image' C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/SKMtools/ImageTrimmer.rb:162:in initialize'
C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/SKMtools/ImageTrimmer.rb:759:in `new'
C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/SKMtools/ImageTrimmer.rb:759

This is a strange error about not being able to find a file...
This runs just fine on my laptop with xp using the same file so i'm guessing that this is operating system based?
Also when migrating the plugins, i did a simple copy and paste into the skp directory on the new machine... don'tknow if any files should be elsewhere given that you use a bit of java on this one.

Any help will be much appreciated....
Thanks

Dave

This indicates that on your new PC either there is not a suitable version of Java installed, or it's not properly enabled, or if it is it does not have its options set correctly to allow 'jar' files to execute. There are several posts about what Java settings to have to allow all of this family of tools working - they all use 'jar' - Java executable applets - that you setting must allow to run in 'Java options'...

Also please check access-rights to the Plugins folder and the SKMtools subfolder and its contents, which must allow read/write/execute etc for everything and everyone... This could cause problems to as some temporary files are written here.

Please come back either with your fix or continuing problems...

Forgive me but i am no expert in these matters.
I have checked and got the latest java and it is enabled so far as I can see.
As far as permissions are concerned, I have little experience in setting specific tags for particular apps but as i mentioned before, the other installed plugin in winxp worked straight out the 'box' and required no additional changes so i'm not sure where to even start switching things in the new windows 7 OS....

Is there anyone out there who has got this working on win7 pro 64bit and skp 8? Did you have to do anything fancy to get it to work?
Maybe they can help point me in the right direction.

Java is currently installed in the x86 directory so as far as i know this is the 32bit version... might it help to get the 64bit version?

Dave, one of the big changes between XP and 7 is that in 7, you'll have to set permissions to make changes to folders. At least the ones that are in the Program folder. As TIG mentioned, make sure you have permissions set to allow changes to the folders he indicated. I did a little thing here about installing zipped plugins and have a paragraph about setting those permissions. Maybe it will help.
