ROI questions

[WangPing]

Hello everyone,
 
I have two questions about using ImageJ:
 
1. Can I rotate an ROI that is drawn manually on the image?
2.  How to change the line color of the ROI drawing?
 
Thanks,
Ping Wang

Use the Edit>Selection>Rotate command.

Use the Edit>Options>Colors command to change the default selection color. Double click on the point tool icon as a shortcut. Use the Edit>Selection>Properties command to change the color of the current selection. Press the “y” key as a shortcut. In the “Properties” dialog you can change the selection’s name, its stack position, its stroke color and its fill color. To set a color, enter a name such as “red”, “yellow”, etc., or a three digit hex number, for example “00ff00” (green). Enter a four digit hex number to set a transparent color, for example “80ff0000” (50% red).

wayne,
Sorry to bother you again, do you know how to stop the auto-close feature for Polygon selections?
(when I draw an ROI with polygon selection, the ROI often closes automatically before I finish it)
Best,
Ping

Hi Ping,

the "Polygon Selection" (3rd tool from the left) is for closed polygons only.

For open polygons, right-click the line icon (5th tool form the left) and select "Segmented Line".
