Yes, QImage should be able to do it all. QImage gives you almost full control 
over images. To convert to monochrome, you would use convertToFormat(). I 
think "density" is ImageMagick's name for dots-per-inch, and QImage has 
dotsPerMeterX() and dotsPerMeterY(). Compression happens when saving the 
image. A quality setting of 100 should do it, but if you need more control 
over compression you can use QImageWriter.
