zooming on a region

Hello ImageJ Users,
I am wondering if there is a pluging to do zooming in/out in an image or image stack and save this action as a movie. any help is highly appreciated in advance. Sincerely, Younes |

Hi. Wayne recently helped me with the below plugin, which I used to make some animations for a presentation. It zooms in until the selected area is the full screen size then you save the stack of images as an animation in ImageJ. I have been saving the stack as avi or animated gif files, but in the code here I slipped in a line that will also save it as an avi into the ij path, which you can uncomment // IJ.saveAs("AVI... ", "myfileZoom.avi") and change to save where you want. For animated gifs, I use the gif stack writer plugin. This code zooms from the onscreen image down to the selection size, using a gradient set differently each time, which is what I needed, but Wayne wrote some code that zooms starting with the selection and the way he did it is smoother and faster, I just haven't fully implemented it in this yet; you can find it in the list a few weeks back or email me and I will find it for you. Hope this helps.

Hello Dear Audrey,
Thanks so much for your nice attention to my email and sending the macro. I saved the text as a macro in the IJ macros folder, opened an image and then run the macro. it shows an error that ''undefined variable in line 1 <import> ij.*". this comes up either I chose a region or not before running macro. sorry i am not good in macro writing. If I put "//" in the first line, the same error comes up for the next lines. I would appreciate it, if you could let me have a macro that I can run it easily. Thanks so much and best regards, Younes On Dec 5, 2007 1:56 PM, audrey karperien <[hidden email]> wrote: > Hi.

That wasn't a macro, it was a plugin.
You need to save it in a file called zoomer_.java, and put it in your plugins folder. You can then use the Plugins->Compile and Run... --David ---------------------------------------- David Hovis Senior Research Associate Department of Materials Science Case Western Reserve University [hidden email] On Dec 6, 2007, at 10:44 AM, Younes Leysi Derilou wrote: > Hello Dear Audrey, > > Thanks so much for your nice attention to my email and sending the > macro.

You are missing a } somewhere. You need to copy and paste starting

Hello Audrey and David,
Thanks so much for your help. I found that the text was misplaced in my email (gmail service). Copying the correct form of the text solved the problem. The plugin works very well, as perfect as the Google map. it sounds 95% scaling is a proper zooming rate to make a movie.

Hi, I just got back from a few days away. I'm glad we could help!
Audrey ----- Original Message ---- From: Younes Leysi Derilou <[hidden email]> To: [hidden email] Sent: Thursday, December 6, 2007 2:07:37 PM Subject: Re: zooming on a region Hello Audrey and David, Thanks so much for your help. I found that the text was misplaced in my email (gmail service). Copying the correct form of the text solved the problem. The plugin works very well, as perfect as the Google map. it sounds 95% scaling is a proper zooming rate to make a movie.
