WCI_NEWPX

Create a pixellation object describing regular pixellisation

Invocation

CALL WCI_NEWPX( DIMS, BASES, SCALES, UNITS, ROTA, ID, STATUS )

Description

Creates a linear pixel to native spherical coordinate mapping. The pixels describe a grid linearly spaced in both axes centred on a special point in the standard coordinate system. The grid may be rotated by an amount ROTA with respect to the standard system.

Arguments

• DIMS[2] = INTEGER (given)
  Number of pixels in each axis. If first element is zero then no pixels are defined and the arguments BASES and SCALES are not accessed
• BASES[2] = REAL (given)
  Local coordinate value in axis units at centre of first pixel
• SCALES[2] = REAL (given)
  Pixel widths in axis units at reference point
• UNITS[2] = CHARACTER*(*) (given)
  Unit strings
• ROTA = DOUBLE (given)
  Rotation of supplied Y axis from latitude like axis, through +ve longitude axis (ie. position angle), in degrees
• ID = INTEGER (returned)
  The ADI identifier of the new Projection object
• STATUS = INTEGER (given and returned)
  The global status.
