Now I can generate TIFF file .However,when I check my tiff file with photoshop,my picture's DPI value is strange!
On setting tag ,I setted like this.
TIFFSetField(tif, TIFFTAG_IMAGEWIDTH, imageW);
TIFFSetField(tif, TIFFTAG_IMAGELENGTH, imageH);
TIFFSetField(tif, TIFFTAG_BITSPERSAMPLE, 8,8,8);
Poom,
On an unrelated point, I believe you are only supposed to pass a single value when setting TIFFTAG_BITSPERSAMPLE.
eg.
TIFFSetField(tif, TIFFTAG_BITSPERSAMPLE, 8 );
Best regards,
