Hi all,

I need u guys' help, I am a newbie in this area. I want to save an image as tiff file. I have able to save the file successfully. However, the saved tiff file is only part of the image intended to save. This is my code below. I think the error lies in the intialisation of the array. So may I know what would be the actual correct intialisation of it? Looking forward for u guys' reply. Thank you.

#define XSIZE 256
#define YSIZE 256
CString name1;
CString name2;
unsigned char array[XSIZE * YSIZE];

    for (int i = 0; i < YSIZE; i++)
            for(int j = 0; j < XSIZE; j++)
                    array[i * XSIZE + j] = (unsigned
char)(j * i);

        CFileDialog dlg(FALSE,"tif","*.tif",
                OFN_HIDEREADONLY | OFN_FILEMUSTEXIST |
OFN_NOCHANGEDIR | OFN_PATHMUSTEXIST |
            OFN_OVERWRITEPROMPT,
                "TIFF Files (*.tif)|*.tif|"
                "All Files (*.*)|*.*||",
                NULL);

    char title[]= {"Save Tif Image"};
        dlg.m_ofn.lpstrTitle= title;

    if( dlg.DoModal() == IDOK )
        {
        name1 = dlg.GetFileName();//must be filename
nt pathname==> crash
                name2.Format("image\\%s.tif",name1);//format the
file

                TIFF* dif = TIFFOpen(name2, "w");
                TIFFSetField(dif,TIFFTAG_IMAGEWIDTH, Gwidth);//get
the imagewidth from the read file

                TIFFSetField(dif, TIFFTAG_PLANARCONFIG,1);
                TIFFSetField(dif, TIFFTAG_PHOTOMETRIC, 1);
                TIFFSetField(dif, TIFFTAG_BITSPERSAMPLE, 8);
                TIFFSetField(dif, TIFFTAG_COMPRESSION, 1);

                for (int k = 0; k < Gheight; k++)//same size of the

original image(Gheight)
                {
                        TIFFWriteScanline(dif, &array[k], k);
                }

                TIFFClose(dif);
        }
        else
                return;
