15
MODIFY/GCURSOR frm_in frm_out y-coord xstart,xend no_curs,degree
16
interactive modification of pixel values in a frame
19
Change data in a line (the input image) interactively via cursor
20
input, by interpolating polynomially between cursor positions.
21
NOTE: The original data will be overwritten.
24
MODIFY/GCURSOR frm_in frm_out y_coord xstart,xend cursors,degree
26
frm_in = input frame name
28
frm_out = output frame after modifications; default input frame
30
y-coord = y-coordinate of the line to modify (default @1)
32
xstart,xend = first and last point on the line to be displayed,
33
entered either as line (pixel) number when
34
prefixed by @, or as real world coordinates
37
cursors = no. of cursor positions (<= 100, default 2)
39
degree = degree of polynomial fit for the interpolation
43
Use any key except (incl. RETURN), or the mouse enter button to
44
validate a cursor position. When the specified number of cursor
45
positions has been specified the interpolation is done and the
46
data is modified. To display these modified data use the SPACE BAR.
47
To exit use the SPACE BAR or exit button on the mouse once more.

MODIFY/GCURSOR GL GLO @1 5,50 2,1
56
Modify frame GL, line 1, between the world coordinates 5 and 50,
57
with 2 cursor positions and linear interpolation. The modified
58
date will be stored in frame GLO.
