Jpeg and pixel

Hi guys,

I've got tthe following question:

Why do my fonts look a bit grubby when I use the jpeg() function? I see
the pixels of the font. The quality is set to 100%.
If this is normal with jpeg(), which function would you propose me to
use instead?
png(), as the help page suggested.  The 'P' in JPEG stands for 
'Photographic', and the format is not intended for text and line diagrams.
Kind regards,
Thomas
