Hi,
For a standalone Pyqgis App I needed such function, so here it is (implemented
for a QgsMapTool) :
from PyQt4 import QtCore
from PyQt4.QtGui import QPixmap , QApplication
# QGIS bindings for mapping functions
from qgis.gui import QgsMapTool
import tempfile
try:
_fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
_fromUtf8 = lambda s: s
class SnapshotTool(QgsMapTool):
''' Provide a tool copy map canvas to clipboard '''
def __init__(self, parent):
QgsMapTool.__init__(self, parent.canvas)
self.mainwindow = parent
self.canvas = parent.canvas
#-------------------------------------------------------------------------------
''' Overridden QgsMapTool Events '''
#-------------------------------------------------------------------------------
def canvasPressEvent(self, event):
''' Get point and transform to map coordinates '''
point = event.pos()
self.transform = self.mainwindow.canvas.getCoordinateTransform()
# returns a QgsPoint object in map coordinates
qgsPoint = self.transform.toMapCoordinates(point.x(), point.y())
self.copyPaste2Clipboard(point, qgsPoint)
def canvasReleaseEvent(self, event):
pass
def copyPaste2Clipboard(self, point, qgsPoint):
''' Get canvas and copy to clipboard '''
# debugging
print "copyPaste2Clipboard()"
pxmap = QPixmap.grabWidget(self.canvas)
QApplication.clipboard().setPixmap(pxmap)

Hi List-members -
Is there in Qgis a function / button / menu-item / short-cut / plugin to make a
simple bitmap copy of the current content of the map-canvas and save it to the
clipboard ? My users need this to make a copy of the map and paste into MS-Word
or other software.
While not part of the QGIS app, one could use this PyQGIS snippet to do so
(tested quickly on macOS 10.11.6 under QGIS 2.14) from the PyQGIS console:
from PyQt4.QtGui import *
QApplication.clipboard().setImage(QImage(QPixmap.grabWidget(iface.mapCanvas())))
This avoids having to re-render the QGraphicsView (QgsMapCanvas) to a paint
device, like an image. Code can be wrapped in a plugin, then have some key
bindings applied (would need some more PyQt).

I really need the functionality for my users and I can't seem to find it. The
closest I've come is the "save as png" menu-item in the project menu. But it's
to cumbersome to use in this case.
Afaics, there's no "save as png" option but "save as image" in Project menu,
option from which you can choose the image file format (bmp, jpg...). It's not
on the clipboard but easier and more accessible than print composer.

I'm familiar with the composer function. My users can't use this neither
because it takes to long to activate (to many choices and to many buttons to
click)
So I've decided to make a simple plugin to cover this functionality. But first
I want to be very sure the function actually is missing ;-)
