Hi,

I tried to take a screenshot by "xwd -root | xwdtopnm |
pnmtopng" but the picture appeared as stretched like below.
I used a week or so old xsrc and pkgsrc/graphics/netpbm.

I also tried to use ImageMagick.  This worked fine like
below.  This is the screenshot what I tried to take.

Google has found following log from netpbm commit logs.
Not sure whether this problem is related to this log.

  Changes 10.11.15:
  * xwdtopnm: Doesn't work with at least one direct color 24 bits-per-pixel
    xwd generated by Xfree86's Xwd.

Few more additional info:
