Any attempts / ideas / thoughts from your side?
EDIT: So four and more digits should be removed? Your sample unfortunately doesn't give examples which data to keep. What if there's alpha or punct chars in there?

ximtoppm(1) General Commands Manual ximtoppm(1)
NAME
ximtoppm - convert an Xim file into a portable pixmap
SYNOPSIS
ximtoppm [--alphaout={alpha-filename,-}] [ximfile]
DESCRIPTION
Reads an Xim file as input. Produces a portable pixmap as output. The Xim toolkit is included in the contrib tree of the X.V11R4 release.
OPTIONS
--alphaout=alpha-filename
ximtoppm creates a PGM (portable graymap) file containing the alpha channel values in the input image. If the input image doesn't
contain an alpha channel, the alpha-filename file contains all zero (transparent) alpha values. If you don't specify --alphaout,
ximtoppm does not generate an alpha file, and if the input image has an alpha channel, ximtoppm simply discards it.
If you specify - as the filename, ximtoppm writes the alpha output to Standard Output and discards the image.
Actually, an Xim image can contain an arbitrary fourth channel -- it need not be an Alpha channel. ximtoppm extracts any fourth
channel it finds as described above; it doesn't matter if it is an alpha channel or not.
See pnmcomp(1) for one way to use the alpha output file.
All options can be abbreviated to their shortest unique prefix.
