Apologies for the extreme basic nature of this question. When I draw a line and type “control d”, the line gets “permanently” drawn (I want this) but the line color changes to gray. Is there a way I can specify the color of the drawn line after control d is typed? Thanks for your help.
There may be two problems …
- The image type is either 8bit, 16bit or 32bit gray-scale.
- There is no color selected in the color chooser (ImageJ main window).
re1: Change the image type to “RGB Color”.
re2: Make an adequate color choice.
- Study the ImageJ User Guide.
Thank you very much. The “RGB” issue was the problem. I had looked at the manual and understood how to specify colors but unfortunately I did not make the leap that my image type was the problem. I’d like to thank you again for your help and patience. All the best, John
