INP=A Input IBIS graphics-1 file
OUT=B Output IBIS graphics-1 file
ITIE=(x1,y1,x2,y2) specifies two tiepoints in the
input.
ITIE=(x1,y1,x2,y2,x3,y3) specifies three tiepoints in
the input.
OTIE=(x1,y1,x2,y2) specifies two tiepoints in the
output.
OTIE=(x1,y1,x2,y2,x3,y3) specifies three tiepoints in
the output.
IUSIZE=(r,s) gives the aspect ratio (r/s)
of the input coordinate sys-
tem. r is the size of one
unit in the first coordinate,
s is the size of one unit in
the second coordinate. This
parameter is used when only
two tiepoints are provided.
OUSIZE=(r,s) gives the aspect ratio (r/s)
of the output coordinate sys
tem. Note: r and s must
correspond to r and s following
the IUSIZE parameter.
This parameter is used in
conjunction with IUSIZE and a
twopoint "polyreg".
SKIP=n Used for skipping nominal data.
Two data words are read and then
n words are skipped, etc.
The skipped data is carried along
unchanged to the output file.
IGNORE=(x,y) causes all points with the
value (x,y) to be ignored by
the transformation. The de-
fault is to ignore (0.,0.).
'FLIP Used for coordinate reversal
(if necessary) when two tie
points are given. For example
LONG-LAT to LINE-SAMPLE or y-x
to LINE-SAMPLE.
'NOPRINT Suppresses program messages to
the screen.
