NAME¶
plstransform - Set a global coordinate transform function
SYNOPSIS¶
plstransform(
coordinate_transform,
coordinate_transform_data)
DESCRIPTION¶
This function can be used to define a coordinate transformation which affects
all elements drawn within the current plot window. The
coordinate_transform function is similar to that provided for the
plmap(3plplot) and
plmeridians(3plplot) functions. The
coordinate_transform_data parameter may be used to pass extra data to
coordinate_transform.
Redacted form: General:
plstransform(coordinate_transform,
coordinate_transform_data)
This function is used in examples 19 and 22.
ARGUMENTS¶
- 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.
