The display server can not invent information, at best it could achieve the zoom-gimp.png result, which is really not enough for visually-impaired people. Here I have only magnified a couple of times, people quite often request for 10x-30x magnification. Also, the control on zooming should really not implemented in the server. Usually you'll also want color inversion or mangling, adding position hints etc. I don't think freedesktop people will be happy to see that added to the display server, so an external solution is needed, currently implemented in Compiz (but lacking access to re-rendering on a bigger pixmap). > Having said that, we do have a magnifier inside GTK, used by the > Inspector. We could make that feature public, and improve it. Interesting. Having mentioned adding the feature to AT-SPI, I'm however interested in putting the interface there, so that not only GTK application can benefit from it, but also Qt, etc. and GTK can just plug its support into AT-SPI. > We definitely do not want to let people inject code into running applications.
