I'm working on a webMathematica application using a linux server (Ubuntu 12.0.4 LTS) with Xtightvnc. Even though the system administrator has done all the possible to set the anti-alising features, we get a poor quality images. Here is an example of code and related results:
image = Style[TraditionalForm[f[x] == (x^2 + 3)/(x - 1)], 50, FontFamily -> "Times New Roman"]; Developer`UseFrontEnd[Export["test.png", image, "PNG", Background -> None]]
here are the results we get In Linux
and here is the same on a Windows server
We also made tests with RealVNC, with the same results. The only way to get a better image is to logging into the console of the web server machine from another machine with an X server running. But, this is not a valid approach, because we have to keep alive the session using a PC only for that. We read many other posts about anti-aliasing configuration for Linux, here on stackexchange and somewhere else, with no avail. Is there anyone experiencing the same problem? Any help is appreciated.
