Description
Please provide a simple, high resolution image export. Our only choices appear to be the File > Save as Image, which has no options, or the Print Composer, which takes several steps and is really designed for creating a hardcopy print.
It would be nice to just have a way to do something like File > Save as Image, but be able to choose a bounding rectangle for the export and specify certain export properties, like resolution or DPI, image format, etc.

This is the only way I know to do it now: http://underdark.wordpress.com/2010/11/30/creating-high-resolution-images-using-qgis/
This way seems to produce mediocre quality images.

I'm going to be bold and say that this is more than normal priority. It's really important that a graphical information system be capable of producing good quality graphics.

From https://issues.qgis.org/wiki/quantum-gis/Bugreports#Steps :
High - a bug which has a major effect on the usability of a package.

It's currently 8 not-so-intuitive steps using the Print Composer: http://arencambre.com/blog/2013/06/02/getting-high-quality-graphics-out-of-qgis/

I would have to agree with Aren on this, I had a client complain how the image resolution was just sub optimal. I spend some time investigating the issue until I came to this issue which references a blog post "output size cannot be specified directly. It simply saves the currently visible map. Most of the time this resolution will not be satisfactory."
I believe with latest improvements in Print Composer is a shame this is still an issue and that I can't set the DPI as in other COTS.

Map Composer/Printing)
If you're working from a print composer you can set the DPI, and export in high resolution. This request is for a way to specify image size when exporting the map canvas from the main window.

qgis development is user driven, if someone will really need this option I guess that could be easily implemented.

Hello, bug triage...
still present in QGIS 2.13. Some hints:
- there is QgisApp::saveMapAsImage method which opens the QFileDialog...
- ...and then launch QgsMapCanvas::SaveAsImage
If a QPixmap is passed as an argument to QgsMapCanvas::SaveAsImage, the saved file gets the resolution of the QPixmap. So perhaps we need to modify QGisApp::saveMapAsImage to ask for a width/height or DPI, compute a QPixmap and use it for QgsMapCanvas::SaveAsImage ? Or is there something else that we can try ?
