i want to convert a tiff file in to a bitmap file. can anybody help me regarding that. i have some problem with the following code

        TIFF *inpimage=NULL;
        inpimage=TIFFOpen("D:\\output_files\\appurgb280multi13x18.tiff", "w");
        uint32 imwidth=800;
        int imheight=800;

//      int h=TIFFGetField(inpimage, TIFFTAG_IMAGEWIDTH, &imwidth);
//      TIFFGetField(inpimage, TIFFTAG_IMAGELENGTH, &imheight);
        tsize_t imlinesize_bytes=TIFFScanlineSize(inpimage);
        uint8 *read_buff=(uint8 *)malloc(imlinesize_bytes*imheight);
        BYTE *bits=read_buff;
        for(int row=1;row<=imheight;row++)
        {
                if (TIFFReadScanline(inpimage,bits, row, 0)==-1)
                        AfxMessageBox("Complete or error",MB_OK,NULL);
                bits=read_buff+row*imwidth;

        }

The return value of TIFFScanlineSize is wrong.

Hi Aparna,

What value returned by TIFFScanlineSize()? Whay do you think it is wrong? What tiffinfo command tells about your file?
