 byte[] b,
 boolean isOCS)

Creates a new HAM Color model using the specified base colors.

Parameters:

aHAMType - Type, must be HAM6 or HAM 8.

size - The size of the color palette.

r - The red colors as 8 bit or as 4 bit values.

g - The green colors as 8 bit or as 4 bit values.

b - The blue colors as 8 bit or as 4 bit values.

isOCS - Set this to true if the colors are 4 bit values.

AmigaHAMColorModel

public AmigaHAMColorModel(int aHAMType,
 int size,
 int[] rgb,
 boolean isOCS)
