a2ping is a Perl script command line utility written for Unix
that converts many raster image and vector graphics formats to
EPS or PDF and other page description formats. Accepted input
file formats are: PS (PostScript), EPS, PDF, PNG, JPEG, TIFF,
PNM, BMP, GIF, LBM, XPM, PCX, TGA. Accepted output formats are:
EPS, PCL5, PDF, PDF1, PBM, PGM, PPM, PS, markedEPS, markedPS,
PNG, XWD, BMP, TIFF, JPEG, GIF, XPM. a2ping delegates the
low-level work to Ghostscript (GS), pdftops and sam2p. a2ping
fixes many glitches during the EPS to EPS conversion, so its
output is often more compatible and better embeddable than its
input.
