; Allow command
line usage
of GIMP such
as:
;
; gimp -i -b
'(with-files "*.png" <body>)'
;
;
where <body>
is the
code that handles whatever processing you want
to
;
perform on the files. There are four variables that are available
; within the <body>:
'basename',
'image',
'filename' and 'layer'.
; The
'basename' is the name
of the
file with its extension removed,
;
while the other three variables are self-explanatory.
; You basically
write your
code as though it were processing a
single
;
'image' and the
'with-files' macro applies it
to all
of the files
; matching the pattern.
;
;
For example,
to invert the colors
of all
of the PNG files
in the
; start directory:
;
; gimp -i -b
'(with-files "*.png" (gimp-drawable-invert layer FALSE) \
; (gimp-
file-save
1 image layer filename))
'
;
;
To do the same thing, but saving them
as jpeg instead:
;
; gimp -i -b
'(with-files "*.png" (gimp-drawable-invert layer FALSE) \
; (gimp-
file-save
1 image layer \
; (
string-
append basename
".jpg") ))
'
; butlast
is needed below.
; Not
in R5RS but
in simply-scheme
and chicken dialects.
; aka drop-right.
; Returns new list with right element deleted.
