Image Trimmer Plugin issue

TIG

it doesnt work though. and why does this winzip file pop up? there should be a pop asking me about scale etc that doest happen either
If you [re]read the usage notes you will see that ImageTrimmer uses some '.jar' applets to perform certain tasks like image manipulation.
For a .jar file to execute properly you need Java installed and active.
Check it's listed in Programs and Features [it usually shipped by default].

Also [as it appears in your case] you CANNOT have the .jar file-type extension associated with any other program.
In your case looks like it's been given over to WinRar.
When you install some compression/decompression programs the default set of file-types which they are set up to open often includes .jar - which is actually a re-suffixed ZIP file - just like a SKM, Style or Layout file.
To stop this happening, open WinRar's preferences and un-check [unassociate] that .jar file-type, save changes and close WinRar.

Now retest ImageTrimmer in SketchUp and see if the .jar applets execute properly [rather than open]...

If it still opens check what app's now 'stolen' .jar... and stop that too...

Dprince

Java is installed and the .jar extension is unchecked in winrar preferences as defaults. how do I find out which program has 'stolen' ,jar

TIG

Clearly WinRar has/had stolen the .jar file-type.
Your screenshot shows that it had actually opened the first of the jar files.
Thus blocking ImageTrimmer's progress...

Do you have both 32 and 64 bit versions installed ?
Have you double-checked their file-type associations exclude .jar ?
Have you any other compression apps installed - if so check their associations too ?

Have you restarted your PC after removing that association ?
Perhaps that is needed to remove the previous associations from the Registry, and let Java claim it once again ??

Dprince

Winrar is 64bit , i have no other compression software installed. I did restart also

TIG

Let's try and force .jar files always to open in Java...

Find the folder:
C:\Users\YourUserName\AppData\Roaming\SketchUp\SketchUp 2018\SketchUp\Plugins\SKMtools
It might be hidden - either reset folder-options to show hidden files, or paste the whole path into a Windows Explorer window's path-bar...
Find one of the .jar files in that folder: e.g. EdgeDetector.jar
Select its icon, right-click > context-menu > "Open with"
In the dialog which opens see what it's set to open with...
Whatever it is set to, choose 'Java' [it might have a longer name, you might have to brose to find it ?] and remember to check the box to set it always to open with this app.
You will undoubtedly get some error messages - don't worry, these are to be expected since we aren't passing a valid in/out file path when we 'Run' a .jar this way...

Retry SketchUp > ImageTrimmer - any improvement ?

Dprince

IT no longer open with Winrar but now sketchup crashes while immage trimmer is in process

TIG

Can you run it with the Ruby Console open, and report any errors you see before the crash...

Can you also post the failing PNG file so I can test it...

PS:
Another thing occurs to me...
It might be an issue with file creation and permissions...
When you installed SketchUp did you do it properly ?
There is only one correct way to do it.
Other ways cause weird and unpredictable permission issues...
Here's how to do it...

Close SketchUp.
Find the installer exe file - probably in your Downloads folder ?
Select its icon, right-click > context-menu > "Run as administrator"
When prompted choose "Repair" [if it's already installed] or "Install" [otherwise].

When it's done restart SketchUp and retry the tool...

If it's still flaky try the above process, but this time choose Uninstall, then immediately rerun it and Install it.

Any custom installed Plugins etc should be unaffected by these processes...

I'm having this issue again downloaded java but got this error when i try to open edgedectator with java

java error.PNG

TIG

It's a somewhat agèd toolset...

Please read all of the usage guidance...

You must have an Image entity selected.

Your system must have Java installed and activated.
Also the .jar file-type must be set to be executed under Java.
Some de/compression apps can hijack that file type, thus preventing Java from executing the file...

The various .ini files are written [temporarily] into a special Temp folder - do you see those ?

Please supply any Ruby Console errors you might get when trying to use the tool...

Dprince

i do have java installed and i use the tool correctly but everytime i try this error happens. the edge detector file name is not selected in winrar. i go inside skm tools folder open with java and then i get the java error as show before

TIG

Your de/compression app WinRar has hijacked the .jar file-type, thereby preventing Java from executing.

It's clear from your screen-shot image that all of your .jar files are associated with WinRar !

Open WinRar and change its Options to ignore .jar file type !!
Nothing but Java should be associated with opening .jar files...

When fixed Java might get to execute them !!!

The retry...

Dprince

I already did that but the issue still remains

TIG

You have NOT disassociated .JAR files from opening in WinRar.
If you had they wouldn't be displayed as 'belonging' to WinRar, and they wouldn't be opening in WinRar - both clearly shown in your screen-shot.

It is a setting in WinRar...
Ensure that .JAR file type is NOT ticked and save changes.

Note that other de/compression tools can also hijack this file-type, causing similar unexpected problems...

.JAR files should be set to always open [execute] with Java.
If they don't automatically revert when the WinRar settings are fixed, you can try Folder Options on a JAR file using 'Open with...' and setting Java as 'always'...

"there were no shapes that could form faces"

the plugin runs, does its work, but in the end gives this message
"there were no shapes that could form faces"

and an empty component is created.

could someone please let me know what i can do.
is the trans png the prob?

thanks,
bob

@Bob
It's almost certain that your PNG is not set up properly.
ImageTrimmer needs the PNG image to contain 2 types of pixel - transparent and opaque.
If you have some semi-transparent pixels they are still seen as being transparent !

So use something like Gimp to edit the PNG...

Flatten it, so that then no pixels are transparent at all.
Now add an Alpha channel [transparency].
Now use the magic-wand to select the colored pixels [probably == 'white'] which you want to be transparent.
Check that the pixels that you'd expect to be 'transparent' are selected properly.
[If needed you can select another 'colored' area - e.g. == 'off-white']
Then Delete them.
Save the PNG with the changes.
Reimport the corrected Image and try ImageTrimmer gain...

Alternatively, attach the problem PNG and I'll fix it... BUT it's best if you understand how to sort our your own mess........

Please read the post, just before yours: https://sketchucation.com/forums/viewtopic.php?p=646097#p646097
I suspect that your PNG's transparency is not set up correctly...

Dprince

I got the same error message after doing what you suggested

Thanks. here's the image
