NAME
xcftopnm - convert xcf files to pnm files SYNOPSIS
xcftopnm [-layer N] [xcffile] DESCRIPTION
This is a rough and slow implementation of a xcf2pnm filter, to be used by other programs that want to be able to read xcf images. If ussage increases this program will doubtlessly be sped up as well. OPTIONS "-layer N" Select the "N"th layer, instead of flattening the whole image. perl v5.8.0 1999-07-29 XCFTOPNM(1)

NAME
PerlIO::via::dynamic - dynamic PerlIO layers SYNOPSIS
open $fh, $fname; $p = PerlIO::via::dynamic->new (translate => sub { $_[1] =~ s/$Filename[:ws-./\]*$/$Filename: $fname$/e}, untranslate => sub { $_[1] =~ s/$Filename[:ws-./\]*$/$Filename$/}); $p->via ($fh); binmode $fh, $p->via; # deprecated DESCRIPTION
"PerlIO::via::dynamic" is used for creating dynamic PerlIO layers. It is useful when the behavior or the layer depends on variables. You should not use this module as via layer directly (ie :via(dynamic)). Use the constructor to create new layers, with two arguments: translate and untranslate. Then use "$p-"via ($fh)> to wrap the handle. Once <$fh> is destroyed, the temporary namespace for the IO layer will be removed. Note that PerlIO::via::dynamic uses the scalar fields to reference to the object representing the dynamic namespace. OPTIONS
translate A function that translate buffer upon write. untranslate A function that translate buffer upon read. use_read Use "READ" instead of "FILL" for the layer. Useful when caller expect exact amount of data from read, and the "untranslate" function might return different length. By default "PerlIO::via::dynamic" creates line-based layer to make "translate" implementation easier. AUTHORS
