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...

ok Thank you TIG.
and stay healthy.

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.

What version of SketchUp are you using? SketchUp 7 as indicated in your profile?

TIG · 30 Jan 2021, 15:58

Run it with the Ruby Console open and see if there are any error messages.
Also you PNG image has not been 'optimized' there are large areas of 'blank-space' around the tree...
Ensure that only the background pixels have transparency and that the image is cropped to minimize those, to speed up processing...
What files in in the temp folder after processing ?

Dave R, no sorry been a while since I've updated my profile, LOL. I'll update shortly

SU V20.0.391 Win 64

Machine is a gen 10 I7 desktop with RTX 3070 64GB RAM

TIG - I'll try cropping the image harder, but this is happening with images that I have had success with in the past as well. In the temp folder that comes up in model location, the only file inside is a copy of the PNG.Edit not the temp folder you were asking about... Going to run with console on then check the temp folder and get back.

The error relating to the creation of the ..\TrimmedImages\Etsy_Oaxacan_rug_zapotec[Edges].dat file suggest several possible issues...

A possibility...

Could you post the PNG you are using...
If that image has all of its pixels with even some transparency, then they will get ignore because they'll be regarded as 'background', so you might end up with nothing to form 'edges' - and no .dat file...

A known cause...
2. Are your .JAR file-types set to be executed [opened] in Java ?
Some compression applications can hijack that file-type, and so they try to open the file instead of letting it run as a the small Java applet [aka JAR] - vital to parse the image's pixel-data.
Check any compression app's setting for file-types and do NOT include .JAR...

Hello TIG,

Your extension offers a lot of promise, and I would like to know your recommendations for trimming and using this image as stampers for an F-14D Tomcat. Thank you!

I cannot install this. Why?
Please help me!

According to your screen shot it is installed. Unsigned doesn't mean it's not installed. As long as you have the loading policy set to allow unsigned extensions to load, they will load. This extension works just fine.

So how to make it work? pls help!!

TIG · 7 Oct 2021, 17:08

If you have your Extension Manager's Loading Policy set to 'Unrestricted' then you need to restart SketchUp...
Then the SKM toolset loads...

There are several code method additions defined.
However, I suspect you want to use one of its specialize tools - e.g. ImageTrimmer...
you haven't explained what your exact problem is...
ImageTrimmer has its own thread in which its usage is explained and discussed in great detail...
It runs from an entry in the Tools menu...

Please explain what you want to do...

Dave R · 7 Oct 2021, 17:22

What do you want to use the extension for? There are some different tools included in the set.

rustar123 · 9 Oct 2021, 16:43

I want to import this jpg to sketchup for push/pull. Then print 3d.
So what is the easiest way to do this? thank's

Dave R · 9 Oct 2021, 16:55

The Image Trimmer feature of SKM Tools would be a good way to go but you need to follow the directions. It requires a PNG not a JPG and the white area needs to be transparent, not white. Use an image editor to make a suitable image and go to town.

Frankly, it's not a very complex thing. I'd probably just import the image as an image and use it as a reference for drawing it with the native drawing tools. The image you uploaded isn't very high resolution either so running Image Trimmer will likely result in pixelated edges.

Here's an example. This was with simplification set to 0.25. Any higher and the curves get straightend out quite a bit.

rustar123 · 9 Oct 2021, 17:10

I have edited transparent for my pic already. But my problem is i can not use ImageTrimmer

Dave R · 9 Oct 2021, 17:24

The message is very clear. You need to save the SketchUp file before you run Image Trimmer.

TIG · 9 Oct 2021, 18:04

@rustar123

You have two problems...

1:
You cannot ImageTrim a PNG in a model that has never been saved - there are temporary files to be saved with the model, so it needs a destination folder....
Save the model then trim it [assuming the PNG is correctly configured]
Looking at it, you could speed up processing time by cropping the PNG to exclude the transparent parts around the edges - every pixel is inspected, so having as few transparent pixels as is possible [e.g. by cropping] will give a quicker result...

2:
More importantly - You have NOT resolved the incorrect file associations for JAR files.
It is explained in various usage tips in the tool's posts.
JAR files MUST be set to open with Java.
Some decompression apps can hijack this JAR file-type - hence the message from your decompression app !
Reset the JAR file-type to open with Java [as it should be...]
Then retry...
