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!

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

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

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

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

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.

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

Dave R

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

TIG

@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...

So how to reset the JAR file-type to open with Java? thank's

TIG

Find a .JAR file - there are 10 such files in the SKM subfolder...
C:\Users\YOURUSERNAME\AppData\Roaming\SketchUp\SketchUp 2021\SketchUp\Plugins\SKMtools
Select a JAR file's icon > right-click > Open with...
I your case the entry won't show 'Java*' but some compression tool, so click Choose Another App...
Find Java in your available apps, then set the .JAR file-type to always open with that... OK to save changes.
Now JAR files will open properly in Java...

If you don't have Java installed, then download and install it...

Seem to be having trouble again getting image trimmer to work.

I've tried this with multiple png files and have also flattened a few of them and removed the background saving them as transparent pngs.

The files were saved prior to importing the image.

Java has been installed and is set to open Jar files

When the image is imported and selected, Image Trimmer runs, but when it stops, nothing appears to have happened. If I explode the image, it completely disappears. There is an image saved in the Image Trimmer folder but it is the same image.

I've tried this many times with different versions of the file. Want to eventually push/pull to get an engraved effect. Any help would be appreciated. I may be missing something but I don't know what it is. Thanks

I've attached some of the image files I attempted to use

Image 003.jpg
Image 002.jpg

TIG

Your [simplified] PNG works for me...
I did 'crop' it slightly in Gimp to optimize its processing time, because any excess transparent pixels around it will be ignored, but are still looked at during the processing.
The two images show the un-smoothed and smoothed outline results...

You seem to have JAR files set right - are there the files show in the TrimmedImages Folder ?

blueman2

Thanks Tig,

Yes I do have a folder of trimmed images

I just tried it with a cropped version and still the same result. Am I doing something wrong in the procedure?

Select surface on model to apply to
import png as image
with image selected, run image trimmer
once it stops running, I explode image

after image trimmer runs

after exploding
Image 004.jpg

Thanks Tig,

I think I see where I was making a mistake, I could not find the trimmed files. I expected them to appear where the original image was. When I expanded the view, I saw them sitting off to the side.

However, now I'm having trouble getting this onto the face of the object so that I can push/pull. I did redo this one more time and requested that the component he stood up. That worked well but then could not accurately get it onto the face. Any tips for doing this?

Thanks again

TIG

If you had told it to make the image-trimmed component stand up it'd be easier to see, and you could then move it into the face, using Move and perhaps Rotate if appropriate.
Since the edges if the facets in the instance are hidden and you'll be PushPulling later I suggest you edit it and Select All, them use Entity-Info to remove and Hidden attributes...
Once it's in place explode the instance and it should 'merge' into the surface, letting you PushPull its faces as desired...

IMPORTANT NOTICE!

There has been a lone report of these tools not working - with a '.jar' file 'opening' rather than 'running'!
Many of these tools use small Java '.jar' executable files that do specific tasks like zip/unzip and image manipulation.

I have found that I can reproduce this weirdness IF I let a 'zip/unzip' application like AlZip or WinRar 'poach' the '.jar' file-type as one that it will open. If so then when Ruby tries to 'open' a '.jar' file instead of it 'executing' in Java [like it should], it 'opens' in the decompression application...

The solution = look at your WinRar etc settings and ensure '.jar' is NOT one of its file-types for opening...

Hi TIG. Hope you are well.
Sorry for another "it's not working for me" post but that is what this is.

I installed the plugin through Extensions Manager, saved a new file, imported an image and run the image trimmer script and get the dots at the bottom and then it blips and nothing happens.

I think I made sure the .jar files open with java like you mention above but I guess I have done something wrong.

I have attached the SketchUp file I am working with if it helps.

Thanks for any help.
