Your PNG file is not suitable for processing.
The transparent background is 0% Alpha [==good]
The foreground is 99% Alpha - ==bad, because it must be 100%, as it is the ImageTrimmer tools sees everything with some transparency - so it's assumed to be all background and there's nothing left to process !
Hence the error message at the end.

It's easily fixed.
I opened the PNG in Gimp [other tools like Photoshop will also do the fix].
Flattened the image to remove all Alpha.
Added an Alpha Channel Layer.
Used the magic-wand to select all of the background pixels [now 'white'].
Delete.
Saved the changes.

Imported the PNG as an Image and processed it with ImageTrimmer.
Took a minute or two, because it has a lot of pixels to go through.
I skipped the 'Smoothing' step at the end as it's so finely pixilated...

The updated PNG is attached - but I suggest you try doing the fix yourself.

There's also a screenshot of the result...

Is this pluging compatible with SU2017?

Dave R · 21 Dec 2018, 22:02

Yes it is compatible with SketchUp 2017.

Updated for compatibility of the ImageTrimmer tool with newer SketchUp versions...

Your plugin issues this message SU2017:
"Could not find the main class: EdgeDetector. Program will exit."

@Vizan

Please read this post about JAR files...
https://sketchucation.com/forums/viewtopic.php?p=642919#p642919
Once you are sure you have your compression tools and Java set up correctly, please retry it...

If the issue continues... It might be because files are copied and written to a Temp folder, and it could be that you have not installed SketchUp properly, and thereby the Temp folder / files have incorrect permissions for reading/writing etc...

To try an resolve this, you can do the following...
Whilst logged into Windows as your usual Windows user, ensure SketchUp is closed.
Find the SketchUp installer's exe file - it's usually in your Downloads folder.
Select the exe file's icon.
Right-click > context-menu > "Run as administrator"
When prompted choose "Repair"
When it completes retry SketchUp and see if it works...

If it still fails, then it might be some latent permissions issues...
Try the following...
Close SketchUp.
Find the folder: C:\Users\YOUR_USER_NAME\AppData\Local\Temp\SKMtools
This is where the needed JAR files get created.
Delete that folder.

Note that folders in the AppData path are hidden by default.
If you enter the path to the Temp folder in a Windows Explorer window it should open directly...
Alternatively, copy/paste this code into the SketchUp Ruby Console and press <enter>, the Temp folder should open for you.
UI.openURL("file:///#{Sketchup.temp_dir}")

When SketchUp restarts and the tool is used, then it will remake that folder and also copy in new JAR files, which should now have proper permissions.

Hi TIG, the ImageTrimmer lets Sketchup crash . in both Versions SKPV17 Make and V19pro.
what am I doing wrong?
Java is installed and not linked with WinRAR etc.

Thank you

TIG · 12 Jun 2020, 13:26

When you say 'crash' what happens - in detail...
If you run it with the Ruby Console open - errors ?
Are there any other errors ?
Have you got a simple PNG to share to test ...

Why not upload the files directly into your post ?
I'll look at them anyway...

PS: the error msg only shows the end - the start is usually the most informative !

deaneau · 12 Jun 2020, 17:17

some forums dont provide this.

I thought I've got your PNG to trim OK.
But SketchUp crashes silently after processing all of the pixels !
I'll re-look at your PNG...

It works with other PNG !
Just did this one...

TIG · 12 Jun 2020, 17:41

If I flatten your PNG it works fine !
See attached...
So it must be some weird interaction of pixels ?

TIG · 12 Jun 2020, 18:01

I thought it's because you have several pixels within the main image [eyes/glasses] that are transparent...
I filled them, flattened the PNG, then made the blue background the alpha-channel and it still crashes !

I'm still investigating...

deaneau · 12 Jun 2020, 19:29

without glasses this works hm, very mysterious

deaneau · 12 Jun 2020, 19:34

TIG if you want you can try this here. I have only safe the svg to the PNG in different resolutions.

It is something to do with some semi-transparent pixels around the eyes/glasses which mess up the outline of the form when the main transparent areas are discounted...

Try flattening the image then deleting only the main 'blue' areas around the body to add back in the transparent alpha-channel...

deaneau · 12 Jun 2020, 21:29

ok Thank you TIG.
and stay healthy.

joshtays · 28 Jan 2021, 18:17

Stumped:
Deleted root level plugin folder and rb file
Downloaded fresh from Sketchucation
re-installed from extension manager
Uninstalled ALL compresssion apps
Ensured all jar files default to java
Ran 2021 installer as admin, repair
deleted SKMTools temp folder

Still getting creating edges, then no dialogue box for simplify, standup, etc, like plugin used to do, processing ends, image remains png.

File is 100% alpha on image and 0% on background, confirmed in PS

TrimmedImages folder with png from SU file is generated in root folder that SU file lives in.
