[Plugin] ImageTrimmer

It is recommended that you as a 'user' have 'administrator rights'.
If you do not / cannot, then at least have the rights to the SKMtools folder and it's contents' permissions set so 'users' can read/write/execute files from that folder...
A automatic Windows [Vista & 7] 'Program Files' set up is often too draconian in limiting your permissions for any program folders/files in it... -

You are indeed correct. This works fine from the master administrator account but for some reason, not from my account in which I am in fact specified as an administrator... ?
I am also listed as having full control of the SKMtools folder.For some reason the 'full' rights are not being given to me.
There are a number of write ups about this on the net... I have followed a few tips on gain full ownership of the OS but no success as yet...If anyone has any bright ideas on how to solve this please step up.... I am not sure that I would be able to live with having to switch users to have to use a plugin...

Have you tried running 'Sketchup as Administrator' [right-click icon menu item] ?
Does that change anything ?
If so change the Sketchup exe [shortcut icon on your desktop will do] to 'run as administrator' permanently.
Then after running it, change it back to be 'ordinary' - this may well kick things into allowing you to run it as expected.
Have you also looked down the Java options for your account?
I have a similar setup to you, without any problems.
Here are my setting that work

TIG...
That's it... working just fine now... !
Incidently, my java settings were the same as yours so i don't think that is to blame. And...before I read your post, as a further test to using the main admin account, I created a new user (with administrator rights)and logged in and everything worked just fine.
So i'm guessing that somewhere in my normal account some access rights are messed up preventing the writing of temp files and it would just be a matter of finding out where to switch things... but i haven't got the time or patience for that.If i follow your advice about setting the shortcut to run as an admistrator, things trim just fine...
I had to reactivate my 1001bit tools but that was easy... so i think i'm just going to leave it running as such for now and one day if i ever to an OS reinstall I'll correct the problem properly.unclebim, you may have success using the same 'patch'... at least it will be an end to your switching users...
Thanks again... have a good weekend

Thank you TIG and davidlouis!

I just found this magnificent plugin, exactly what I was looking for! Unfortunately, I do not and cannot have administrator access to anything on my Windows 7 work computer. Not to mention I don't have Java on it and am not allowed to install it.

If you can't have Java installed you are knacked!
If you could have Java working there are work-around to get the tools loading/running from a 'personal directory' - your IT guys would need to allow a small ruby to run from their side to let your personal files' load...
BUT without Java the SKM tools can't function...
So the only solution is to do it at home and bring it in - thereby shaming your office into dragging themselves into the 21st century !
Alternatively send [email/PM] me the PNG images and I'll email/PM the cutout SKP back to you within 12hours at $20 each [Pre-PayPalled] ???

Thanks for the response, TIG. Always quick and helpful. I'll see if I can convince IT to install Java and give me appropriate rights. No matter how many sources of 2d and 3d people, trees, furniture, cars, backgrounds, textures, etc, I always seem to need/want to find/make some more...
-
First thanks TIG for one more wonderful plugin. I tried to use it to make some face me components of trees, but for me it was painful slow...I read earlier in this topic that the best thing to do is to make smaller image. I could do that, but I want best resolution SU can handle. So, what I have in mind is - could U make this internal process? I mean, first scale down the image, than the rest of code, than brings back original resolution, all by plugin?

Hi,
for this workflow I have used a very time-consuming method in the past. I have vectorized the "PNG", using an external application and than imported the "DXF" into Sketchup than I erased manually all unwanted edges.
The "TIG" tool seems to be a great tool for this purpose. I've just now taken notice of it. But unfortunately it does not seem to work for me. When I start it the progress bar started also and a window of my compression program opens. The tool works and terminates the operation normally. But the "TrimmedImage" folder is empty. I don't know what is wrong. Any help would be appreciated.

You must have Java enabled and the control-panel preferences set to allow 'jar' files to execute locally - these are needed to execute the code needed to manipulate the image data outside of Ruby...
A 'jar' file is a compiled Java-applet - in this case the various SKM/Image jar files are devised to do individual simple tasks not possible with basic Ruby...
You currently have 'jar' files set to open with you compression program!
These 'jar' files need to be left as executable-files set to open/run with Java...
Edit your compression program options to exclude 'jar' as one of the file types to open with that app' and ensure they run with Java itself... This is my Alzip settings NOT to open 'jar' files when I double-click on them...

Hi TIG,
I had not thought about this simple solution. Now it works as it should. A great tool and a great developer. Thank you very much TIG.

Hi,
I've used the plugin again with two PNGs. With the EURO PNG it works flawlessly. The second generated PNG with the lady does not work. So I suspect that the Second PNG is flawed. Does anyone know what could be the error in this PNG?

First off the time taken to process is related to the number of pixels and although you can't see them there are hundreds around the woman. You could crop it to just her and some background...
If there is even the slightest transparency associated with the woman's pixels they are taken as transparent too, so they could all be ignored when finding edges and therefore there are then no edges to process - hence the error message...
I'll have a look at the woman.PNG and check it out... -
Here goes... I did the following...
Edited the PNG with Gimp.
Auto-cropped it to minimize the background area.
Flattened it to remove all transparency.
Layer > Added Alpha-channel, to allow transparency again.
Selected the now white background with the magic-wand and deleted it.
Saved it.
Used as an Image in a SKP approximating it to the height of a woman.
It ImageTrimmed quite quickly and produced this result...
WomanImageTrimmed.skpHere's the edited PNG too

Have you any tips for trees?
-
Hi TIG,
thank you for the explanation and effort. I took the photo in Photoshop and cropped again and it worked so well. Thanks again.

Hi Rich,
For trees, it basically works just like it "TIG" has described above. Unfortunately, within the image transparent areas may not be present as I noted in a experiment. The edges must first be processed cleanly. The picture shows a try with GIMP.

On LoRes .png I don't have an issue but with HiRes it goes for a long think and sometimes crashes SU.
I was wondering if there was a particular set of guidelines that allow for optimum output with relatively low processing times.
Nice tree Charly

Don't do it you fool!
"Just step away from the tree... put your mouse down where I can see it..."But seriously though folks
Spend time up front getting the PNG right.
Crop it tightly so there's minimal transparent background.
Make sure that the outline isn't too complex, e.g. any thin leaves, twigs, branches etc, that are less than ~2pxs wide will be ignored because the edges they define will be considered 'coincident' and therefore won't make a face, BUT they'll still clog up the processing time if they are included in the pixels to look at - so either erase them so they are not considered OR fatten them up so they are used.
The edges of every 'hole' in the PNG have to be individually processed, 'smoothed' etc - so the more holes the longer it'll take to complete.
Be patient - if it whites-out it's almost certainly still working away on things, but it's just taking its time - so have a coffee [or a glass of beer!] or two and chill out...
This palm took too many hours to process in the background while I did something else [>7!]...
It has a lot of thin 'fronds' to process...
