9.2.2 UETONF

1.
Function
Performs fill of 2-D contours using the image-data draw function.
2.
Call
CALL UETONF(Z,MX,NX,NY)
3.
Explanation of Parameters
Z (R) A 2-D array of MX * NY. The NX * NY portion is used in the draw routine.
MXn (I) The first adjustable dimension of array Z.
NX (I) The first adjustable dimension of array Z used in the draw routine
NY (I) The second adjustable dimension of array Z used in the draw routine

Notes
(a)
This is nearly compatible with the UETONE, but only solid tone patterns can be specified.
(b)
This routine cannot be used on devices without image draw functions.
(c)
The color is determined by linearly interpolating the value (z) from the surrounding 4 points for each pixel. Therefore, the boundary between colors is usually a curved line.
