      I keep getting the can't find or load main class c:\users\Rick\appdata\local\temp\skmtools\edgedetector.jar

      The files are there ? So it's a failure to load ??
      Where do you get this message ?
      Is it a Java dialog that pops up ?
      This suggests Java is NOT set up to execute the .jar files ?
      My settings are attached...

      There's nothing wrong with your png file[s] as Dave has shown...

        The image "example-1.jpg is what I've been expecting from "imagetrimmer".
        Please verify.

        Also attached is a screen shot of the java error message box which flashes on and then off so fast I had to do a screen capture video to be able to read the message.

        My java settings are identical with the exception of the one about Java plug-in.
        My Java control panel doesn't have this check box category.

          This is weird, as jar seems to be associated with Java πŸ˜•
          Please confirm that the jar files are in the correct Temp folder... πŸ˜’

              Attached are images of both directories (google and user/temp)
              They are identical since i copied the google one to the temp one earlier.
              If you know that's a problem let me know.
              I know less than squat about Java and I've only been using Windows 8.1 for about a month.
              I use quite a few other ruby scripts (some are yours) in Sketchup 8 without any problems.
              This is the only one however that uses .jar files.

                I don't have windows but this is the link page to test your java instal

                http://java.com/en/download/installed.jsp

                might be a good place to start

                  Ran the test.
                  Seems to be the right version that I installed.

                  Do you know of at least one other person running this ruby script in win8.1 and sketchup 8?
                  Just trying to figure out where the problem might be. (other than me)

                    interestingly if I run this[includes the link] in Menu >> Window >> 'Ruby Console' using

                    @dlg = UI;;WebDialog.new("Java", true,"java", 900, 900, 200, 200, true, true)
                    @dlg.set_url("http://java.com/en/download/installed.jsp")
                    @dlg.show_modal
                    

                    I get a missing plugin alert? which may be signs of a permissions issue?

                    I'll dig deeper

                      I'm using Win7 on this PC.
                      I find that running your @dlg code in the Ruby Console worked fine for me - no errors, and it confirms latest Java is installed [v7.45].

                      @rahdad1
                      One very odd thing I noticed in your 'SKMtools' folder...
                      Where did that 'META-INF' subfolder come from?
                      It's not in the standard install RBZ etc ?
                      What's in it ?

                      Incidentally, are you an Administartor ?
                      If not, then give yourself that power in the Users Control-Panel...
                      Also, as well as FULL security permissions 'for all' to your Plugins folder... is SketchUp.exe set to 'always run as administrator' under Properties > Compatibility ?

                        After total frustration, I decided to delete the SKMtools files and folder and START over.
                        The problems probably started in the installation itself.

                        This is the same procedure I originally used........

                        I downloaded the file SKMtools_V20121214.rbz
                        While in Sketchup under preferences/extensions/ install extension
                        I "chose" SKMtools_V20121214.rbz

                        It seemed to load however when I went looking for image trimmer under the tools drop-down
                        it was missing.

                        I then separately downloaded the file "SKMtools_loader.rb and put it in the plugins folder.

                        Now Imagetrimmer is listed in the drop-down menu.

                        Clicking it the first time brings up an error window that says it can't find SKMtools_loader.rb even though it's in the Google SketchUp 8\Plugins folder

                        Obviously I've done something wrong from the very beginning.
                        Please explain the correct way to install this.

                          If you auto-install the toolset from its current RBZ that is all you need to do.
                          You get a 'SKMtools.rb' and its subfolder of several helper files, called 'SKMtools'.
                          The obsolete 'SKMtools_loader.rb' file is NOT needed.
                          In fact having it will break things !
                          I assume you found it and then downloaded that from somewhere else, and installed it in frustration.
                          It is now several years out of date !
                          Please remove it from your Plugins folder...
                          It will break things if it's forced in there !

                          If you have proper FULL security permission for your Plugins folder then the current toolset actually deletes that very file from the Plugins folder [if you have it installed] as it loads, and it does a tidy-up.
                          If you have limited permissions, or you have subsequently manually reinstall the '_loader', then you could get issues as it loads and messes with the latest code...

                          Can I suggest that you manually delete all SKM files and the whole 'SKMtools' subfolder.
                          Then reinstall the SKMtools toolset from its latest RBZ.
                          Then restart SketchUp and then retry the tools.

                            I totally removed the SKMtools folder, SKMtools.rb, SKMtools_loader.rb and anything left in the user-temp-skmtools folder.

                            I am administrator and I have full control in the plugins folder and SKMtools folder as shown in the attached images.

                            From the SketchUcation toolbar within Sketchup, I found and auto-installed the SKMtools.
                            It confirmed successful install when it was completed.

                            I ran imagetrimmer and, like always, the java error window pops up with the same message about "can't find or locate main class c:......\edgedetector.jar"

                            It's probably a java / win8 problem which I don't expect you to help me solve.
                            Your program obviously works fine based on other users successfully using it.
                            I'll keep researching and hopefully figure it out.
                            If you want to continue to suggest other things to try, I'm welcome to that also.

                                  Reread the instructions, and comments in the thread.
                                  The Image must be imported as an Image, NOT a texture.
                                  It must be a PNG.
                                  It must have a transparency alpha-channel.
                                  The background pixels to be removed must on that.
                                  ALL other pixels must be 100% opaque.
                                  If they have any transparency at all they will also be removed !
                                  The simplest way to sort this is to open the PNG in Gimp [or PhotoShop] and 'Flatten' it to remove transparency, then add in the transparency alpha-channel, then use the magic-wand to select all of the background pixels and <delete>.
                                  Save the PNG and import it as an Image into your SKP.

                                  Select it.
                                  Choose ImageTrimmer on the Tools menu.
                                  Answer the prompts...

                                  Run with the Ruby Console open to see if there are any error-massages...

                                  Because this tool uses Java '.jar' files [small executables] to process images, you need to have Java installed and enabled on your computer [the usual default].
                                  Also check that the .jar file-type is set to open with Java [execute] and NOT to open in your [de]compression application - some hijack various file extensions that are used by things like Java and stop them executing...

                                  If all of this fails, post clear details of what is wrong...

                                    I have tried this numerous different ways and couldn't get it to work.
                                    -Saved PNG as GIF to remove semitransparent pixels, then back to PNG
                                    -Most of the time doesn't get past 'scanning pixels'even on a 600x600px image
                                    -When it does complete I am left with a hidden outline of the image with no actual image in it.

                                    I am trying to put a plant library together and this would make life soo much easier.

                                      All transparent pixels are assumed to be background and are ignored by ImageTrimmer.
                                      So even slightly transparent ones go !

                                      Using Gimp.
                                      Flatten the PNG to remove transparency.
                                      The 'background' usually reverts to opaque white pixels [or sometimes black]
                                      Add a transparent alpha layer.
                                      Use the magic wand to select all of the opaque white pixels forming the background.
                                      Press the 'Delete' key to remove them,
                                      Now you should see a transparent background - two-tone gray checks.
                                      Save the PNG file [in Gimp this is called 'Export...'].
                                      That PNG when Imported as an Image into SketchUp should now ImageTrim properly.

                                      Note that the ImageTrimming is only accurate to a 'pixel width' - so areas of opaque pixels that are only one [or sometimes two] pixels wide will be missed out too - because the transparent ones are taken as the 'border' and if a border's edges are effectively 'coincident' no face can form and the unfaced edges are auto-removed too...

                                        What face style do you have selected? The image becomes a texture during the process so if you have Monochrome selected as the current face style, you'll get the result you describe.

                                          That might well be the issue πŸ˜’

                                            Face style is shaded with textures.
                                            -I loaded a 500x600px plant png with transparent background into photoshop
                                            -I flattened the image, selected colour 'white' and deleted out pure white pixels, leaving the white frame around my plant, i.e. no semi-transparency.
                                            -import the image into sketchup 2014 pro with only imagetrimmer plugin installed.
                                            -scanning pixels frozen at 91%.

                                            I should point out that I have got this to work for some files, just not these plants.
                                            Are there any other specific png settings?

                                            I get 'not responding' from sketchup plugins all the time on big jobs, but this doesn't seem to complete no matter how long i leave it, and on such a small image it seems there is something else wrong.

                                            Cheers

                                            edit: for anyone wanting to try it out with these images, they are at ozbreed.com.au.

                                            having tried a few images now it seems the edge complexity of these plants is killing it
