linux image from clipboard

I'd like to access the graphics in the linux clipboard, to save it as a file. I'm doing this in a Python/Tkinter program, so I asked about it (http://stackoverflow.com/questions/6817600/save-the-image-in-the-clipboatd-in-python-tkinter) but internally (in python) there's no hope.

Instead, I can accept to use an external utility to do it - yet I cannot find one.

Do you know of any terminal-based utility able to take the clipboard c开发者_如何学Content and save it as an image file?

Copy:

xclip -selection clipboard in.png

Shorter:

xclip -se c in.png

Paste:

xclip -selection clipboard -target image/png -out > out.png

Shorter version:

xclip -se c -t image/png -o > out.png

From this Unix & Linux question:

https://unix.stackexchange.com/questions/145131/copy-image-from-clipboard-to-file

You can also use image/tiff and image/jpeg.

I couldn't find any tool to do it, so I wrote this small Python script. It requires pygtk.

#!/usr/bin/python
"""
Save image from clipboard to file
"""

import sys
import glob
from optparse import OptionParser

def def_file():
    """
    Return default file name
    """
    files = glob.glob("img???.png")
    if len(files) < 1:
        return 'img001.png'
    maxf = 0
    for f in files:
        try:
            n = int(f[3:6])
            maxf = max(n, maxf)
        except ValueError:
            pass
    return 'img{:03d}.png'.format(maxf+1)


usage = """%prog [option] [filename]
Save image from clipboard to file in PNG format."""

op = OptionParser(usage=usage)
op.add_option("-o", "--open", action="store_true", dest="open", default=False, 
        help="Open saved file with default program (using xdg-open)")
(options, args) = op.parse_args()

if len(args) > 1:
    parser.error("Only one argument expected")
    sys.exit(1)
elif len(args) == 1:
    fname = args[0]
else:
    fname = def_file()

import gtk
clipboard = gtk.clipboard_get()
image = clipboard.wait_for_image()
if image is not None:
    image.save(fname, "png")
    print "PNG image saved to file", fname
    if options.open:
        import subprocess
        subprocess.call(["xdg-open", fname])
else:
    print "No image in clipboard found"

Take a look at xsel and xclip.

Otherwise, you might find some more information on wikipedia.

Using pyqt is easy.

def copy_image():
    clipboard=variableofapp.clipboard()
    if (clipboard.mimeData().hasImage()):
        img=x.pixmap()
        img.save('file.png',"PNG")
