How do I use TIG's Image trimmer?

Greetings, after some research, and extension downloading I can’t seem to figure out how to use the Image trimmer. When I try to use it on an image I imported it always give me a " You selected the Image first" message. And yes, im using a .png file.

I’ve tried exploding and it does nothing. I tried searching for a video, which I found but it was in another language. I just don’t know what I’m doing wrong.

Please help.

Quick back story, I was asked if I could create an svg file from a drawing so that it could be used on the Shaper Origin CNC router. That i was able to do with an extension download with no problem. Then I was asked if I could somehow use an image to create a profile for the svg file. And that is where I’m stuck.

Why didn’t you ask this question in the ImageTrimmer thread at SketchUcation ?

Did you use the SKM-tool RBZ download which ImageTrimmer is a subset of ?

I’d be far more likely to notice it there, and others there would be helpful…
That said, please read the usage notes in the first post in the thread…

Note the requirement to have Java installed and for JAR files to be associated with Java and NOT some decompression app.
Also note it only works on PNG files and assumes all pixels with some transparency are to be discarded, so only gave what you ant to lose transparent.
In your PNG there is no transparent pixels so the trimming is almost instantaneous - resulting in the same thing !
Also crop your PNG as tightly as possible, otherwise it’ll waste time checking pixels that you don’t want any way.

ImageTrimmer is really intended for use with something more complicated…
The PNG you attached is so simple you could easily import it as an Image, then explode, then draw a rectangle over it and fillet the corners, the add the twiddly bits for the central ‘masonic badge’…
I’ve attached a v2017 SKP I did in a few seconds ‘by hand’ - no Plugin needed…

The quality of the texture’s image is not great but if you have a better image then use that…
Logo.skp (230.4 KB)

PS: As a result of this post I have found that v2019.2 fails with ImageTrimmer - earlier SketchUp versions are OK… Raising this with the powers that be,

As far as the image I shared, what I was hoping to do it to push/pull the different aspects of the logo for engraving. have the letters, for example be extruded above the the background for depth or somehow make it into a usuable SVG file.

I do see what you did as far as cropping the image closer , thank you for taking the time to do that. I will check out that thread.

I did download the SKMtools extension. I will check about the Java/JAR relationship. My IT department will probably have to help with that.

Thank you again for your time

That’s not something that is within ths scope of Image Trimmer. You could use Bitmap Tracer but you would need to create a BMP file from your PNG, first. It’s available from here.

Thank you. Im putting alot more work/research than I had planned when our guy asked about svg files. Now im in a research worm hole.

Thank you, just installed the tracer. Let’s see how that works out.

I already gave you a manually made SKP with the outline.
If you want to add internal faces and PushPull them up/down it’ll be easily done by hand.
Just draw over the image to make new loops, then select/PushPull the face…

I think you are making this harder than it needs to be :face_with_raised_eyebrow:

You’re probably right about me making it harder than it should be. I think it’s the general idea of tracing it, as I imagine I have to trace it free hand which doesn’t seem easy to do with mouse.

You can make outlines of lines, rectangles, arcs/fillets etc, the freehand tool is not normally needed for this kind of thing.
Drawing some guides might also help…
Some of your drawn shapes might intersect with others, and then you will need to erase unwanted edges, to leave the required shape behind.

Much the same as I did with the main outline I already made for you…

If you want complex Bezier curves there are Plugins available for this - although I think that what you need is all possible with native tools…

PS: Use a Style where the profiles are set thicker than other edges, then you can easily distinguish when you have ‘cut’ the face as you wish…

Hi,
I was just wondering if the ImageTrimmer is now ok for SketchUp v2019.2?

Cheers

My ImageTrimmer works in all current SketchUp versions, but you must heed the oft’ repeated advice about .jar file ssetup etc…
Please look at the tool’s thread at SketchUcation, you’ll get better tips and feedback there…
It’s part of my SKM toolset downloadable from the PluginStore…
