2011.05.31 10:54 "Write Tile", by Jorge Martin
Hello,
I am trying to write a tiled TIFF file but the
function TIFFWriteTile is always returning "Can not write tiles to a
stripped image" I have set the fields Tilewidth and TileLength and I do not
know what is happening because I did not set any field about the strips. How
can I solve this issue? I pasted some code that I used to write the TIFF:
TIFF * TIFFDst = TIFFOpen(pszDstFileName, "w");
//Store the differen TAG info from the TIFF input file
TIFFSetField(OutTIFF, TIFFTAG_IMAGELENGTH, 3559);
TIFFSetField(OutTIFF, TIFFTAG_IMAGEWIDTH, 701);
TIFFSetField(OutTIFF, TIFFTAG_BITSPERSAMPLE, 8);
TIFFSetField(OutTIFF, TIFFTAG_SAMPLESPERPIXEL, 1);
TIFFSetField(OutTIFF, TIFFTAG_PHOTOMETRIC, 1);
TIFFSetField(OutTIFF, TIFFTAG_RESOLUTIONUNIT,RESUNIT_CENTIMETER);
TIFFSetField(OutTIFF, TIFFTAG_COMPRESSION, COMPRESSION_NONE);
TIFFSetField(OutTIFF, TIFFTAG_THRESHHOLDING, THRESHHOLD_BILEVEL);
TIFFSetField(OutTIFF, TIFFTAG_IMAGEDESCRIPTION, "L1A_PAN");
TIFFSetField(OutTIFF, TIFFTAG_ORIENTATION, ORIENTATION_TOPLEFT);
TIFFSetField(OutTIFF, TIFFTAG_XRESOLUTION, 1);
TIFFSetField(OutTIFF, TIFFTAG_YRESOLUTION, 1);
TIFFSetField(OutTIFF, TIFFTAG_PLANARCONFIG, 1);
TIFFSetField(OutTIFF, TIFFTAG_DATETIME, "2011:05:18 14:15:15");
//TILES INFO
TIFFGetField(OutTIFF, TIFFTAG_TILEWIDTH, 128);
TIFFGetField(OutTIFF, TIFFTAG_TILELENGTH, 128);
TIFFSetField(OutTIFF, TIFFTAG_XPOSITION, 1);
TIFFSetField(OutTIFF, TIFFTAG_YPOSITION, 1);
TIFFSetField(OutTIFF, TIFFTAG_SAMPLEFORMAT, SAMPLEFORMAT_UINT);
int index =0;
for ( y = 0; y < ImageLength; y += TileLength )
{
for (x = 0; x < ImageWidth; x += TileWidth )
{
//Loop to write the matrix data into a buffer.
index =0;
for (int i = y; i < y+TileLength; i++)
{
for (int j = x; j < x+TileWidth; j++)
{
//get the data from the matrix
buffer[index] =
(uint8)(*m_TIFFImage.m_ImagMatrix[0].Values).coeff(i,j);
index++;
}
}
TIFFWriteTile(TIFFDst, (tdata_t)buffer, x, y, 0, 0);
}
}
TIFFClose(TIFFDst);
TIFFDst = NULL;
Best Regards,
Jorge
