RHBA-2012:0287 - Bug Fix Advisory

Topic

Updated netpbm packages that fix several bugs are now available for Red Hat
Enterprise Linux 5.

Description

The netpbm package contains a library of functions which support programs for
handling various graphics file formats, including .pbm (portable bitmaps), .pgm
(portable graymaps), .pnm (portable anymaps), .ppm (portable pixmaps) and
others.

This update fixes the following bugs:

• Prior to this update, the pnmtofiasco and fiascotopnm utilities could not

correctly read the bitfile on IBM System z and PowerPC platforms. As a
consequence, images were not correctly converted. This update modifies
pnmtofiasco so that the files are successfully converted. (BZ#509366)

• Prior to this update, the manual page for the pamperspective utility contained

several misprints which could be confusing for users. This update corrects the
misprints. (BZ#510501)

• Prior to this update, the pgmtopbm utility encountered problems when

converting grayscale pgm images to black and white pbm images. As a consequence,
the pgmtopbm utility generated an empty white image. This update modifies the
conversion process so that the pbm image is displayed in black and white as
expected. (BZ#510759)

• Prior to this update, the xwd image header contained incorrect information

about the layout and the bit order when running on the rdesktop window. As a
consequence, the xwdtopnm utility generated the wrong image colors. This update
modifies the the xwd image header so that the correct output is displayed.
(BZ#574362)

• Prior to this update, the manual pages for the pnmtojbig and pcdovtoppm

utilities were missing. This update adds the missing documentation. (BZ#699633)

All users of netpbm are advised to upgrade to these updated packages, which fix
these bugs.
