@Tim Edwards I was using Xcircuit for drawing a schematic. How can the schematic file be exported in other formats apart from Xcircuit extension??

Menu

Netlist->Write SPICE netlist

No I mean a image format to represent the schematic.

Xcircuit's file format is PostScript, so it is an image format. You can use

ps2pdf

or

convert

(ImageMagick) if you want to change it to something else.
