Arrows

[Knecht, David]

The pdf manual recently released has a section on adding arrows to images. It indicates that you get a choice of arrow types in the dialog and you can add non-destructively.  I have not been able to make it do either.  I do not see the red arrowhead in the arrow box indicating you can double click for options and I do not have a selection that I can add non-destructively to an image.  Am I missing something?  I am running the latest ImageJ on Mac OSX.  Dave

What version of ImageJ are you using? I see by searching the release notes at http://rsbweb.nih.gov/ij/notes.html that the arrow tool was added in v1.43n and that support for double-headed arrows was added in v1.43o. You access the arrow tool by right clicking on the line tool.
