plscmap1la: Set cmap1 colors and alpha transparency using a piece-wise linear relationship
Declaration
public void scmap1la(ColorSpace itype, Double[] intensity, Double[] coord1, Double[] coord2, Double[] coord3, Double[] alpha, Boolean[] alt_hue_path)Parameters
| Type | Name | Description |
|---|---|---|
| ColorSpace | itype | true: RGB, false: HLS. |
| Double[] | intensity | A vector containing the cmap1 intensity index (0.0-1.0) in ascending order for each control point. |
| Double[] | coord1 | A vector containing the first coordinate (H or R) for each control point. |
| Double[] | coord2 | A vector containing the second coordinate (L or G) for each control point. |
| Double[] | coord3 | A vector containing the third coordinate (S or B) for each control point. |
| Double[] | alpha | A vector containing the alpha transparency value (0.0-1.0) for each control point. |
| Boolean[] | alt_hue_path | A vector (with npts - 1 elements) containing the alternative interpolation method Boolean value for each control point interval. (alt_hue_path[i] refers to the interpolation interval between the i and i + 1 control points). |
Remarks
This is a variant of plscmap1l that supports alpha channel transparency. It sets cmap1 colors using a piece-wise linear relationship between cmap1 intensity index (0.0-1.0) and position in HLS or RGB color space (see ) with alpha transparency value (0.0-1.0). It may be called at any time.
