Read ICC profile information of an image

Question

Dear community,
for my further implementation I need some information about the ICC profile used for an actual image edited inside Photoshop. How can I read the ICC informations about an image?
I am implementing an export plug-in and found some ICC component inside the ExportRecord struct, called:
Handle iCCprofileData; /**< Handle containing the ICC profile for the image. (NULL if none.)
                                            Photoshop allocates the handle using the Photoshop handle suite.
                                            The handle is unlocked while calling the plug-in.
                                            The handle is valid from  \c ExportSelectorStart to \c ExportSelectorFinish
                                            Photoshop frees the handle after \c ExportSelectorFinish. */
int32 iCCprofileSize; /**< Size of profile. */
int32 canUseICCProfiles; /**< Non-zero if the host can accept or export ICC profiles .
                                            If this is zero, the plug-in should not set or dereference \c iCCprofileData. */
What I am not understand:
How can I read the iCCprofileData and which information will be delivered by the iCCprofileSize?
For iCCprofileData I got int values like @179952120 or @179952176. They differ for every loaded image. Seems that I just read the memory address. The "Handle" points to an empty char '\0'. I have no idea how to work with the datatype "Handle" correctly ...
For the iCCprofileSize I got integer values like 544 for the embedded profile Adobe RGB (1998), 3144 for the working color space sRGB IEC61966-2.1 or also 3144 for the embedded profile without color management:
embedded profile  = Adobe RGB (1998) -> iCCprofileSize = 544 (or sometimes 560)
working color space = sRGB IEC61966-2.1 -> iCCprofileSize = 3144
embedded profile = without color management -> iCCprofileSize = 3144
embedded profile = SWOP2006_Coated3v2 -> iCCprofileSize = 2747952
working color space = Coated FOGRA39 (ISO 12647-2:2004) -> iCCprofileSize = 654352
embedded profile = without color management -> iCCprofileSize = 654352
The variable canUseICCProfiles delivers always the value 1. As well if I selected the embedded profile without color management.
Can I infer from the iCCprofileSize which profile will be used by each image?
Does somebody has more experience with these there members (iCCprofileData, iCCprofileSize and canUseICCProfiles) of the struct ExportRecord?
I would be grateful for some hints.
King regards,

hai,
i paste the java source code for getting each pixel value of an image.i think that this code is usefull to you.
import java.awt.image.PixelGrabber;
import java.awt.Toolkit;
import java.awt.Image;
class getpixel2
public static void main(String args[]) throws Exception
Image image = Toolkit.getDefaultToolkit().getImage("D:\\one.jpg");
if(image==null)
System.out.println("NO FIle");
PixelGrabber grabber = new PixelGrabber(image, 0, 0, -1, -1, false);
if (grabber.grabPixels())
int width = grabber.getWidth();
int height = grabber.getHeight();
if (isGreyscaleImage(grabber))
byte[] data = (byte[]) grabber.getPixels();
else
int[] data = (int[]) grabber.getPixels();
for(int i=0;i<data.length;i++)
int r = (data[i] >> 16) & 0xff;
int g = (data[i] >> 8) & 0xff;
int b = (data[i] >> 0) & 0xff;
System.out.println("(R,G,B)=("+r+","+g+","+b+")");
public static final boolean isGreyscaleImage(PixelGrabber pg)
return pg.getPixels() instanceof byte[];
}
