nanogui: Thread: Drawing Iamge from buffer

Dear all,
I written code to draw an image ,reading data from 
memory. I used following code , but it not worked.
Image size is [512 * 512] W * H in pixels.

////////// code ////////////////

int* ImageData;
int nCount=0;

ImageData = (int*)malloc(sizeof(int)*(512*512));

// to show black image i filled allocated mem with // zero
// this not worked

GrDrawImageFromBuffer(rawwidgetid,rawwidgetgc,0,0,512,512,ImageData,512,0);

if any one knows answer to this please mail me.
Thanking You,
Sheetalkumar.

Its the 8th argument that got you.  'size' should be the size of the buffer
(in your case, thats 512 * 512 * sizeof(int)).
