Graphics Formats for Linux Having looked at some of the common
graphics formats, we finish up with a quick look at some
available programs and libraries for converting images. xv and
ImageMagick These two X programs display, convert, and
manipulate images. xv can read and write JPEG, GIF, TIFF,
PBM/PGM/PPM, and X formats, although it cannot display 24bit
images as 24bit. In addition to format conversions, xv can
perform simple image manipulations, e.g., rotate, flip, crop,
magnify, and gamma correction. ImageMagick supports the formats
xv does, plus TGA. It can send output directly to a postscript
printer and has more image manipulation capabilities than xv:
cut, copy, paste, resize, flip, flop, rotate, invert, emboss,
and more, on the whole or on part of the image. The canonical
way to view and convert from PostScript (including EPS) is
ghostscript. Ghostscript operates both from the command line
options and interactively. Input is always a PostScript file and
output may be any of several different file form
