Progress bar during resizing
 
|
Dear all,
How can I get the progress bar to appear during a resizing manipulation ? Let say that you have a 1 000 x 1 000 px image and want to resize it to 10 000 x 10 000 px. It takes more than a second (20 seconds on my system), though the progress bar does not appear. Is there a limited list of functions for which the progress bar is supposed to appear ? Thanks !

Hi Nico,
ImageJ shows the progress bar only for some operations, mainly for those that are slow with more "typical" image sizes (0.1-10 Mpixels). Your output image has 100 Mpxl. Resizing is done at a rather low level (ImageProcessor) and it is just a small part of the operation in several other commands (e.g. "Make Montage"), so adding a progress bar for resizing would give a meaningless (or flickering) progress bar for other operations that use resizing. So ImageJ just shows a status message when resizing, counting the images that have to be resized (for the case that a stack is resized). Unfortunately, that status message goes away as soon as the mouse is moved over an image, it yields for the coordinates & value readout.

Dear all,
Could anyone please instruct me how to rotate an ROI that was drawn by the "Polygon Selections" tool? Also after rotation, the ROI should be still editable, say, can change its size by dragging its vertices. Thanks any help. Kind regards, Ping -- ImageJ mailing list: http://imagej.nih.gov/ij/list.html |

Hi Michael !
Thank you for your clarifications ! Is there any chance that, in a macro, one can display a "progress bar" in the log window using parallel threads ? Or any other way to get an idea about the progress of a resizing step in a macro ? Thanks !

Hi Ping,
if you rotate a polygon with Edit>Selection>Rotate, it remains a polygon and can be still edited. http://rsb.info.nih.gov/ij/docs/guide/146-27.html#toc-Subsubsection-27.12.13 Michael ________________________________________________________________ On Apr 15, 2015, at 18:03, WangPing wrote: > Dear all, > > Could anyone please instruct me how to rotate an ROI that was drawn by the "Polygon Selections" tool?

Hi Michael, thank you so much for the quick response, yes it works for the Polygon ROI!!
Additional question is about an ROI drawn by Oval tool: after rotation I found I can move it but its size is no longer editable, any idea to make the size of Oval ROI still changeable after rotation?

Also how could you draw an Oval ROI with its axis in any orientation? Ping

Hi Ping,
After rotation of the ellipse, you can do Edit/Selection/Fit Ellipse to get access back to the knobs for size adjustment.

Hi Ping,
if you use Elliptical Selections instead of Oval Selections, they can be drawn in any orientation and rotated with the mouse. Right-click the 'Oval Selection' icon to get them. http://rsb.info.nih.gov/ij/docs/guide/146-19.html#sub:Elliptical-Selection-Tool P.S. sometimes it pays off to read the manual (though this is an old-fashioned approach ;-) Michael ________________________________________________________________ On Apr 15, 2015, at 18:24, WangPing wrote: > Hi Michael, thank you so much for the quick response, yes it works for the Polygon ROI!! > Additional question is about an ROI drawn by Oval tool: after rotation I found I can move it but its size is no longer editable, any idea to make the size of Oval ROI still changeable after rotation? > > Kind regards, > Ping > >> Date: Wed, 15 Apr 2015 18:14:38 +0200 >> From: [hidden email] >> Subject: Re: How to rotate an ROI that is drawn by "Polygon selections" tool? >> To: [hidden email] >> >> Hi Ping, >> >> if you rotate a polygon with Edit>Selection>Rotate, it remains a polygon and can be still edited. >> http://rsb.info.nih.gov/ij/docs/guide/146-27.html#toc-Subsubsection-27.12.13 >> >> Michael >> ________________________________________________________________ >> On Apr 15, 2015, at 18:03, WangPing wrote: >> >>> Dear all, >>> >>> Could anyone please instruct me how to rotate an ROI that was drawn by the "Polygon Selections" tool?

Hi Nico,
sorry, you can't get the progress of a resize operation from outside the ImageProcessor method that does the job. One could have a parallel thread with that shows just some progress bar with arbitrary speed, and terminates if the operation is done, but a solution with macros only will be a rather tricky hack. It is easier with a plugin than with a macro for the progress bar, because then one could stop it via a 'call' command. I have written a quick and dirty one, below. After 'Compile&Run', you have to do "Refresh Menus" to make it appear somewhere in the Plugins menu, then you can start it in a separate thread with doCommand.
