plstransform
( | coordinate_transform, |
coordinate_transform_data) ; |
This function can be used to define a coordinate transformation
which affects all elements drawn within the current plot window.
The
function is similar to that provided for the coordinate_transform
plmap
and
plmeridians
functions. The
parameter may be used to pass extra data to
coordinate_transform_data
.
coordinate_transform
coordinate_transform
(void (*) (PLFLT, PLFLT, PLFLT *, PLFLT *, PLPointer)
, input)
Pointer to a function that defines a transformation from the input (x, y) coordinate to a new plot world coordinate. A NULL pointer means that no transform is applied.
coordinate_transform_data
(PLPointer
, input)
Optional extra data for
.
coordinate_transform
Redacted form:
General: plstransform(coordinate_transform, coordinate_transform_data)
This function is used in examples 19 and 22.
