It can be done using setResolution, but you need to do it before loading an image.Try something like this:
The quality of the image produced from the PDF can be changed by setting the density (which is the DPI) before reading in the PDF - this gets past to ghostscript (gs) underneath which rasterizes the PDF. To get a good result, supersample at double the density you require, and use resample to get back to the desired DPI. Remember to change the colorspace to RGB if you want an RGB JPEG.
A typical command line version for convert might be:
If you need to crop it, a -shave command following the resample is usually sensible, if the image is centred within the page.
