If I use this below to write a tiff that started as single strip tiff, there is no problem. But when I try to write an image that started out as multiple strips it crashes. Do I "need" to save the image multiple strips? And if I do, can someone help in the right direction (I have experimented to try and force multiple strips with a group 4 image, with no luck).

TIFFSetField(out,TIFFTAG_PLANARCONFIG,PLANARCONFIG_CONTIG); if(mbCompression){TIFFSetField(tif, TIFFTAG_COMPRESSION, mTiffCompression);}; if(mbSubfileType){TIFFSetField(tif, TIFFTAG_SUBFILETYPE, muliSubfileType);};

if(mbResolutionUnit){TIFFSetField(tif, TIFFTAG_RESOLUTIONUNIT, musiResolutionUnit);}; if(mbXResolution){TIFFSetField(tif, TIFFTAG_XRESOLUTION, mfTiffXresolution);}; if(mbYResolution){TIFFSetField(tif, TIFFTAG_YRESOLUTION, mfTiffYresolution);}; if(mbImageWidth){TIFFSetField(tif, TIFFTAG_IMAGEWIDTH, muliImageWidth);}; if(mbImageLength){TIFFSetField(tif, TIFFTAG_IMAGELENGTH, muliImageHeight);};

if(mbPhotometricInterpretation){TIFFSetField(tif, TIFFTAG_PHOTOMETRIC ,musiPhotoMetric);}; if(mbBitsPerSample){TIFFSetField(tif, TIFFTAG_BITSPERSAMPLE ,musiBitPerSample);}; if(mbFillOrder){TIFFSetField(tif, TIFFTAG_FILLORDER, musiFillOrder);}; if(mbSamplesPerPixel){TIFFSetField(tif, TIFFTAG_SAMPLESPERPIXEL, musiSamplePerPixel);};

if(mbuf){TIFFWriteEncodedStrip(tif, 0, mbuf, (muliImageWidth * muliImageHeight) / 8);};

//My attempt at creating multiple strip. //if(mbRowsPerStrip){TIFFSetField(tif, TIFFTAG_ROWSPERSTRIP, muliRowsPerStrip);};

//tdata_t outbuf;
//char * p = (char*)mbuf;
//for(tstrip_t counter = 0; counter < mstrip; counter++){

//   outbuf = (void*)&p[counter * (muliImageWidth * muliRowsPerStrip)/8];
//   TIFFWriteEncodedStrip(out, counter, outbuf, (muliImageWidth *

muliRowsPerStrip)/8);
//};
