Always returns DirectColorModel (may be based on MemoryImageSource used as source for the PixelGRabber...see code).

Code used:

byte[] indexArray = new byte[256];

for (int i=0; i<indexArray.length; i++) {
indexArray[i] = (byte)i;
}

int[] bitArray = {8,8,8};
int[] maskArray = {0xff0000,0x00ff00,0x0000ff};

ColorModel[] cms = {
new IndexColorModel(24,8,indexArray,indexArray,indexArray,-1),
new ComponentColorModel(new ICC_ColorSpace(ICC_Profile.getInstance(ColorSpace.CS_sRGB)),bitArray,false,
false,-1),
new DirectColorModel(24,0xff0000,0x00ff00,0x0000ff)
};

int[] testPixels = new int[1000];

for (int i=0; i<testPixels.length; i++) {
testPixels[i] = 0xffffff;
}

DirectColorModel dCM = new DirectColorModel(24,0xff0000,0x00ff00,0x0000ff);

MemoryImageSource source = new
MemoryImageSource(50,50,dCM,testPixels,0,50);

int x,y,w,h;

x = 10;
y = 10;
w = 10;
h = 10;

ColorModel currentCM = null;

int[] pix = new int[1000];

PixelGrabber pg = new PixelGrabber(
source,
x,
y,
w,
h,
pix,
0,
w
);


for (int i=0; i<cms.length; i++) {

currentCM = cms[i];

pg.setColorModel(currentCM);

result = (pg.getColorModel() == currentCM);

if (!result) {
msg += "PixelGrabber(" +

").setColorModel(" +

"\n";

                     System.out.println(msg + "\n");
