Is there any library that can easily manipulate Bitmap (bmp) file?

[sin kanti]

Hi all,

In my project, i wanna resize original bmp file to 60x40 and make them
1-bit color.
Then, store each bit it into an array for data processing.

Is there any library that can do what i want in Ruby?

Thank you,

Sinchai

Often, the easiest way to manipulate images is to convert them to PNM=20
format, and then manipulate that (and then convert back). You can do this=20
with something like the netpbm package <http://netpbm.sourceforge.net/> or=
=20
ImageMagick, or something similar.

It's not a ruby-specific solution, but it's cross-platform, and I use often=
=20
use that to manipulate images with ruby. =3D)

(And I'm sure someone else could point out a native ruby PNM library, or a=
=20
binding to netpbm or ImageMagick.)
