Hi,
I found the plugin ROIScaler on this list: http://rsb.info.nih.gov/ij/developer/api/allclasses-noframe.html With details: http://rsb.info.nih.gov/ij/developer/api/ij/plugin/RoiScaler.html How is this plugin installed and used?

Hi Avi,
this RoiScaler is the built-in ImageJ command responsible for Edit>Selection>Scale. You see this if you type CTRL-L (cmd-L on Macs) in ImageJ and enter "scale": It will tell you that the "Scale..." in Edit>Selection calls ij.plugin.RoiScaler. In a java program such as a plugin, you can call newRoi = RoiScaler.scale(roi, xscale, yscale, centered); Michael ________________________________________________________________ On Mar 20, 2015, at 16:30, Avi Leftin wrote: > Hi, > > I found the plugin ROIScaler on this list: > > http://rsb.info.nih.gov/ij/developer/api/allclasses-noframe.html > > With details: > > http://rsb.info.nih.gov/ij/developer/api/ij/plugin/RoiScaler.html > > How is this plugin installed and used? > > Regards, > > Avi > > > -- > ImageJ mailing list: http://imagej.nih.gov/ij/list.html -- ImageJ mailing list: http://imagej.nih.gov/ij/list.html |

Hey,
Any idea of how to write this into a macro with double/numeric input instead of the ordinary usage? run("Scale... ", "x=0.80 y=0.80 centered"); I'd like to use a loop in my macro that increments the x= and y= inputs, while keeping centered a constant.

Thanks Michael,
In the java call newRoi = RoiScaler.scale(roi, xscale, yscale, centered); The xscale is double/numeric, as is yscale? I'd like to use this in a loop within a macro that increments the xscale and yscale factors, while leaving centered where the original ROI was centered. What are the inputs for roi, and centered? How would such a call be used in a loop?

Hi Avi,
is the problem having variables in the run("Scale... " command? theScale = 0,7; or theScale = getNumber("enter the scale", 0.8); then run("Scale... ", "x=&theScale y=&theScale centered"); or run("Scale... ", "x="+theScale+" y="+theScale+" centered"); The latter uses the '+' for String concatenation.

Thanks Michael. That did the trick. Thank you for the syntax lesson :)
