Copy and Paste in a plugin

[Gabriel Landini]

Hi,
Rather than calling:  IJ.run("Copy"); and IJ.run("Paste"); in a plugin, can
somebody please suggest a way to directly copy from an existing ROI in an
ImagePlus and paste it directly into another ROI in a different ImagePlus?  
(the ROIs are the same type and size).

And similarly is there a way to execute a "Duplicate..." command so it is
guaranteed that a particular image is being duplicated ?
I just want the ROI to be duplicated, as when using the Duplicate... command,
but I wonder if calling IJ.run("Duplicate...", "_temp"); one runs the risk (as
in macros) of not accessing the right image if one mistakenly clicks into
another image while the plugin is being executed.

Many thanks

Gabriel

Hi Gabriel,

you could use imp.copy(false) and imp2.paste. It does the same  
without "IJ.run", also using the clipboard.

One level deeper - without the clipboard - I fear that you would have  
to write it yourself, with a loop and ip.getPixel, ip.set (or  
ip.putPixel).

The Blitter commands like ip.copyBits always take a full ip as a  
source; this won't help.

Thank you Michael, yes that is what I was looking for.

For this 2nd question, I found the Duplicater class so I will use just that.

Many thanks again!
