scol0a(Int32, Int32, Int32, Int32, Double)

plscol0a: Set 8-bit RGB values and PLFLT alpha transparency value for given cmap0 color index

Declaration
public void scol0a(Int32 icol0, Int32 r, Int32 g, Int32 b, Double alpha)
Parameters
Type Name Description
Int32 icol0

Color index. Must be less than the maximum number of colors (which is set by default, by plscmap0n, or even by plscmap0).
Int32 r

Unsigned 8-bit integer (0-255) representing the degree of red in the color.
Int32 g

Unsigned 8-bit integer (0-255) representing the degree of green in the color.
Int32 b

Unsigned 8-bit integer (0-255) representing the degree of blue in the color.
Double alpha

Value of the alpha transparency in the range (0.0-1.0).
Remarks

Set 8-bit RGB value and PLFLT alpha transparency value for given cmap0 (see ) index. Overwrites the previous color value for the given index and, thus, does not result in any additional allocation of space for colors.
