Save Tiff with color palette

[Cipper]

Hello!

I am trying to save an image to a .tif file. When saving as an RGB standard image everything is ok. But when I try to save the file as a LUT/palette color image the app crashes.

Here is the piece of code

int _tmain(int argc, _TCHAR* argv[])
{
TIFF* tif = TIFFOpen("test.tif", "w");

TIFFSetField(tif, TIFFTAG_IMAGEWIDTH, 100);
TIFFSetField(tif, TIFFTAG_IMAGELENGTH, 100);

TIFFSetField(tif, TIFFTAG_XRESOLUTION, 96);
TIFFSetField(tif, TIFFTAG_YRESOLUTION, 96);

TIFFSetField(tif, TIFFTAG_RESOLUTIONUNIT, 2);
TIFFSetField(tif, TIFFTAG_PLANARCONFIG, PLANARCONFIG_CONTIG);
TIFFSetField(tif, TIFFTAG_BITSPERSAMPLE, 8);


TIFFSetField(tif, TIFFTAG_SAMPLESPERPIXEL, 1);
TIFFSetField(tif, TIFFTAG_PHOTOMETRIC, PHOTOMETRIC_PALETTE);
TIFFSetField(tif, TIFFTAG_ROWSPERSTRIP, TIFFDefaultStripSize(tif, (unsigned long)-1));


unsigned short *r, *g, *b;
r = (unsigned short *) _TIFFmalloc(sizeof(unsigned short) * 3 * 10);
g = r + 10;
b = g + 10;

srand(time(0));

for (int i = 0; i < 10; ++i)
{
r[i] = (unsigned short) rand() % 255;//((*(pImageLUT->_pColorTable))[i]._R);
g[i] = (unsigned short) rand() % 255;//((*(pImageLUT->_pColorTable))[i]._G);
b[i] = (unsigned short) rand() % 255;//((*(pImageLUT->_pColorTable))[i]._B);
}


TIFFSetField(tif, TIFFTAG_COLORMAP, r, g, b);

unsigned char* lineBuffLUT = new unsigned char[100] ;

srand(time(0));

for(int y = 0; y < 100; y++)
{
for(int i = 0; i < 100; i++)
lineBuffLUT[i] = rand()%10;

TIFFWriteScanline(tif, lineBuffLUT, y) ;
}

_TIFFfree(r);

TIFFClose(tif);
return 0;
}

The app crashes on TiffClose(tif), to be more accurate, in crashes on TiffCleanup().

Do you have any idea why this might happen?


Thank you,
