Android HC: maGetImageData problem

Hi,

RES_IMG_RGB is a 3 pixel png embedded image w/ a red, a green and a blue pixel created w/ MS Paint.

The code:

char s[100];
int *i = new int[100]; 
MARect r = {0, 0, 3, 1}; 
maGetImageData(RES_IMG_RGB, i, &r, 3); 
sprintf(s, "%x %x %x", i[0], i[1], i[2]);

Returns:

FFFF0000 FF00FF00 FF0000FF on Android 2.x/MoRE
0000FFFF 00FF00FF FF0000FF on Android 3.x

Regards,

Diego
