The GD driver produces png, jpeg, and gif images, using devices by the same name. The GD driver is unicode enabled. Text is anti-aliased, but lines and shades are not.
The available driver options are:
optimise: Optimise PNG palette when possible
def_black15: Define idx 15 as black. If the background is "whiteish" (from "-bg" option), force index 15 (traditionally white) to be "black"
swp_red15: Swap index 1 (usually red) and 1 (usually white); always done after "black15"; quite useful for quick changes to web pages
8bit: Palette (8 bit) mode
24bit: Truecolor (24 bit) mode
text: Use driver text (FreeType)
smooth: Turn text smoothing on (1) or off (0)
