trouble pasting in plugin

[jvander]

I am having a problem with pasting.  I have a workaround, but I would like to know the underlying issue as it may explain other issues I see from time to time.  In the code below I show that I copy the contents of one image into the clipboard, then (not showing all the code below) I make a larger image and then replicate the smaller image over and over to fill the larger image.

When I use IJ.run("Paste"); it works fine

When I use imp1.paste(); it only copies the last location

Below is the code.  Please advise on the difference in behavior.

(Running ImageJ 1.50g4    Java 1.8.0_60 64 bit  Mac OS 10.10.5)

thanks,

Joe

Hi Joe,

you might try roi.endPaste() after each paste operation, to ensure the
operation is properly completed.
You can get the roi via imp1.getRoi() after imp1.setRoi(...).

Hello Michael,

The addition of endPaste did indeed fix the issue.  I need to do some more reading on understanding Roi operations.  In any event I have a working plugin.

thanks very much for the help.

Joe
