I have a simple .tif, created in Photoshop, that consists of a horizontal line,
a vertical line, and some text, and that (thanks to Frank) is now a
georeferenced GeoTIFF. Is there a command line tool that will read in the
georeferenced GeoTIFF and write out a georeferenced vector file, likely a

Hi: when we try and display a DigitalGlobe image in QGIS we only see a dark

we are obviously late on the initial schedule... We aim at issuing

the opportunity to commit the driver if you're confident enough it won't
