I have a .bmp image file, and always returns the error when i convert from a bitmap:

gs -sDEVICE=png256 -o ./teste.png ./teste.bmp

Solution

  • Ghostscript doesn't process .bmp files, it accepts PDF or PostScript. You could write a PostScript program to place a .bmp image (see for example viewgif.ps) but that's not the same thing at all.

    You need an image processing application such as ImageMagick, as suggested by Mark Setchell above.
