fkbox Compute the bounding box of a Fcurves
fkbox [-z z] in . . . . [box ]
-z z : magnification factor to apply to the box
in : input (Fcurves)
. (screen output) : minimum along X coordinate
. (screen output) : minimum along Y coordinate
. (screen output) : maximum along X coordinate
. (screen output) : maximum along Y coordinate
box : create bounding box as a Fcurve
void fkbox (cs , xmin , ymin , xmax , ymax , z , box )
Fcurves cs ;
float *xmin , *ymin , *xmax , *ymax ;
float *z ;
Fcurve box ;
This module computes the bounding box enclosing a set of Fcurves. The output
xmin, xmax, ymin and ymax are the minimum and maximum
values taken by the x and y coordinates over all points of all curves.
-z option is used, then the size of the bounding box is
magnified by z along each axis (the center of the box being kept).
If requested, the bounding box is stored in a Fcurve.
