      Here's an updated toolset: http://sketchucation.com/forums/viewtopic.php?p=293677#p293677
      The SKMtools Temp folder that is needed to process Image files etc, is now made in the User's Temp folder [OS specific] rather that the ../Plugins/SKMtools folder, avoiding potential permission issues...

        Here's another updated toolset: http://sketchucation.com/forums/viewtopic.php?p=293677#p293677
        It fixes a silly typo in the ImageTrimmer code which prevented it from completing its tasks... 😳

          I'm running into a similar problem with image trimmer running and hope mine has a simple answer. After clicking image trimmer from the dropdown box, it appears to start processing but quickly diplays an windowed dos error message indicating it can't find EdgeDetector.jar.


          At the top of the window it reads: C:\Program Files\Java\jre7\bin\java.exe

          The message reads: Error: Could not find or load main class C:\Users\Rick\AppData\Local\Temp\SKMtools\EdgeDetector.jar


          Why java is looking there, I don't know because the file is where it's supposed to be at Google SketchUp 8\Plugins\SKMtools\EdgeDetector.jar

          Quick Background..... New computer with Windows 8. No java came preinstalled so loaded the latest 64bit version from their website. jar files were originally associated to another program so I had to change associated program to java.exe

          All folder permissions in SKMtools (and below) have "full control" rights

          What am I missing???

            To avoid issues with permissions to the SKMtools folder the files are now replicated in your own personal folder tree, to which you should have FULL rights...
            The minimum rights that 'everyone' needs to the main SKMtools folder is READ - FULL read/write is best...

            If you open:
            C:\Users\Rick\AppData\Local\Temp\SKMtools
            are there any files in there ?
            The jar files needed should be copied across...
            Does C:\Users\Rick\AppData\Local\Temp\SKMtools have FULL permissions ?

            This CAN be fixed πŸ˜„

              <<If you open: C:\Users\Rick\AppData\Local\Temp\SKMtools
              are there any files in there ?>>

              There is one subfolder called.... META-INF
              and 4 files EdgeDetector.class
              Edgedetector.jar
              from.ini
              to.ini

              <<The jar files needed should be copied across...>>

              jar files are now copied across

              <<Does C:\Users\Rick\AppData\Local\Temp\SKMtools have FULL permissions ?>>
              Yes

              After opening the SU file, clicking the "image" and then clicking "imagetrimmer" from the drop-down list under tools,
              I can see it processing. The error box (content is the same as before) pops up again very briefly and dissappears like before.
              This time it processes much longer and then finishes. Nothing new in the window. There is a new folder in the project directory called "TrimmedImages" with the png file in it.
              The script appears to stop at that point. I'm expecting to see a new componant in the SU window with the trimmed image.

              Any ideas of what I need to do next???

                Do you definitely have Java enabled and .jar files set to execute [open] with Java and NOT a decompression tool.

                I suspect that you might not got your PNG files transparency set up suitably.

                Remember that ALL pixels with some transparency set [even a tiny %] will be discarded and trimmed off.

                So... you might need to edit the png in an image editor like Gimp or Photoshop...

                Firstly 'Flatten' the image to remove transparency from every pixel.
                Now use its 'Layers > Transparency > Add Alpha Channel...' [or something like that]
                Then use the editor's 'magic-wand' tool to select all of the background pixels and <delete> them.
                The background should now disappear, and be 100% transparent.
                It's also a good idea to use 'Crop' on the image to trim it exactly to the bounds of the solid parts: every pixel has to be considered and processed by ImageTrimmer so it is always best to minimize the number of pixels in the image you are going to process...

                Save [export?] the png and import it into an empty SKP... retry ImageTrimmer on it...

                If still no joy then... then post the image as an attachment here - or PM it to me if it's 'sensitive'.

                  Attached are two pngs

                  Is java working? I don't know but I presume not. I keep getting the can't find or load main class c:\users\Rick\appdata\local\temp\skmtools\edgedetector.jar
                  Even though the progress line says "making edges", I don't think it has the image/data to actually do this. It's just running the loop until it times out.

                  I have both the jre and jdk java packages loaded and the web test on their web site indicates it is loaded and working correctly.
                  File association is set to run jave.exe (even tried javaw.exe)

                  I know java won't run on the "start"(metro) screen in win8 or win8.1 but I'm running sketchup on the desktop mode anyway.

                  Any other suggestions?

                    There's nothing wrong with Image Trimmer, anyway. It works perfectly for me.

                      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.

                              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.

                                  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

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

                                      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].

                                      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.
