I am using tools::compactPDF for reducing the size of some pdf-files
with GhostScript. I had some trouble in the beginning as the
documentation seems not to match the usage of the function. For
GhostScript, one has to set the argument gs_cmd, which has the following
description:
gs_cmd - Character string giving the path to the GhostScript executable,
if that is to be used. On Windows this is the path to 'gswin32c.exe' or
'gswin64c.exe'. If "", the function will try to find a platform-specific
path to GhostScript.
The first part seems not to work as described. If gs_cmd is given, this
is passed to find_gs_cmd. This function will then call:
Sys.which(gs_cmd)
which rather takes the name of the executable as input. I guess either
the documentation should be changed to refer to the name of the
GhostScript executable, or the function should be changed to use the
given path.
Best wishes,
Jon
