Linux & IJ System clipboard

[Gabriel Landini]

Hi,
For quite some time I have been wondering why I could not use the clipboard
from IJ into another application such as Libreoffice. I always suspected that
it was a Java bug.

It turns out that that under KDE, Klipper (the clipboard) has an option
(configure Klipper) that comes as a default with an "ignore images" and "text
selection only". Doh!

De-selecting those allows copying from a ROI in IJ into a Libreoffice document
and lets you see which images have been copied too.

Maybe somebody else finds this useful (I never thought that there was a lot to
be configured for the clipboard!).

Cheers

Gabriel

For what it's worth, I have the same problem on Linux, and found out that
Java's clipboard handling does not offer images in .bmp format while
LibreOffice *only* accepts that format (on X11 specifically, i.e. Unix, no
less).

My common work-around is to have a GIMP instance open that can paste
images when they are offered in .png format, copy that to the system, and
then paste in LibreOffice.

Ciao,

The clipboard on X11 is traditionally quite a bit broken. The problem is
that the original cut buffer really only allows for text. The clipboard
was introduced later as a kind of call-back mechanism, where you can
enquire for the clipboard contents in a certain format.

For images, the format the LibreOffice asks for *exclusively* is in bmp
format. Java only offers the images in xpm, png and jpg format, though.

GIMP is cleverer and asks for png format, but offers also in bmp format.

Hence "Copy to System" in IJ, Ctrl+Shift+V, Ctrl+A, Ctrl+C in GIMP and
Ctrl+V in LibreOffice work.
