Thanks Matt + other respondents to my question.
I should have been more specific - The raster image/data I am trying to export is a DEM which I would like to transfer to a 3D modelling system. Using the raster/conversion/translate menu I have managed to get most of the way, using the ASCII gridded XYZ format output. This produces a text file with XY coordinates and the elevation Z. BUT I would like the X and Y in planar grid coordinates (metres). I have selected a plane grid projection as the “target SRS” but it still produces X and Y as lat/long coordinates. Any suggestions about what I am doing wrong?

If you look at the box that states the command line gdaltranslate is using, the -o flag is the output format. You can check the box next to the command line and change that manually if it doesn't change to tiff automatically. Think it's a bug. the output format options can be googled "-o zmap" works.

RGB/greyscale photographic type images such as an aerial photograph or a georeferenced scan of a map are one. There's not a lot of point exporting those as text. There are also Raster images where the RGB / black bands represent a frequency or attribute from a satellite or remote sensing instrument, you might want to convert those to a different format to use in a different package or just select a single band to work on. Single band raster such as grids or DEMS are another type of raster. The last 2 types above can be saved in alternate formats under the "convert format" option in the raster dropdown options somewhere, can't remember the exact name. I usually do this with grids / single band rasters. the command line option is gdaltranslate. "save as" doesn't work the same way it does as with vector data. I don't have QGIS open at the so I can't recommend a format but I think CSV is one of them.
