NAME
plscmap1la - Set color map1 colors using a piece-wise linear relationshipSYNOPSIS
plscmap1la(itype, npts, pos, coord1, coord2, coord3, coord4, rev)DESCRIPTION
This is a version of plscmap1l(3plplot) that supports alpha transparency. It sets color map1 colors using a piece-wise linear relationship between position in the color map (from 0 to 1) and position in HLS or RGB color space (see the PLplot documentation) with alpha value (0.0 - 1.0). It may be called at any time. This function is used in example 30.
ARGUMENTS
- itype (PLBOOL, input)
- true: RGB, false: HLS.
- npts (PLINT, input)
- number of control points
- pos (PLFLT *, input)
- position for each control point (between 0.0 and 1.0, in ascending order)
- coord1 (PLFLT *, input)
- first coordinate (H or R) for each control point
- coord2 (PLFLT *, input)
- second coordinate (L or G) for each control point
- coord3 (PLFLT *, input)
- third coordinate (S or B) for each control point
- coord4 (PLFLT *, input)
- fourth coordinate, the alpha value for each control point
- rev (PLBOOL: *, input)
- reverse flag for each control point. (rev[i] refers to the interpolation interval between the i and i + 1 control points).
