Ok -

A very rough, but functional first version of the plugin is now in https://github.com/Frederikssund/QGIS-canvas-to-clipboard/

  • No shortcut
  • No about-box, nice explanations or help text
  • No copyright statements
  • Only one button that create a bitmap of the current map-canvas and put into the clipboard
But it works  !

Is it possible that I could get some feedback on how it works on other platforms than Windows from someone(s) with access to Linux and/or Mac?
Plugin works fine here on macOS 10.11.6 with QGS 2.14. Thanks for putting it together. Glad to see it works cross-platform without quirks!
Here on macOS, the clipboard contents are recognized as a TIFF-formatted image (of course, not GeoTIFF, that would be too cool - though I don't know where one could *paste* a GeoTIFF). Guessing that the clipboard format might be platform-specific and managed by Qt.
Also here on macOS, there is a thin gray border, which I think is always part of the widget's scene. IMO actually makes the capture better, if there is a partial or wrapped white background shown in the canvas and the user is pasting into a white-background document (common scenario).
Richard, if you are looking to add this to master, maybe it should go under the View menu, e.g. View -> Copy to Clipboard (maybe right under 'Zoom Out'?), since Edit menu seems to be just for editing features and is fully greyed-out if only working with rasters. Another appropriate menu might be Project -> Copy to Clipboard, under 'Save as Image...', though I think under View is maybe better.
Be good to have a default key binding, though I can't think of a decent cross-platform keystroke right now.

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).

Black Hills, South Dakota   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 ;-)
