Brad, first of all I would like to thank you for your answer. But I still have problems.

imagen is a black and white image that I have loaded from a bmp file. It is

imagen->height=3290
imagen->width = 2552
imagen->bits_per_pixel=8;
the imagen->data includes only 0s (background) and 1s (foreground)

I wish to save it as a tiff image. Your remark sounds logical and I did it, however now it stops running when y=2 in

if (TIFFWriteScanline(out,bits, y, 0)==-1) cout<<"Complete or error";

I am not sure if in either of

TIFFSetField(out, TIFFTAG_SAMPLESPERPIXEL, 1);

TIFFSetField(out, TIFFTAG_BITSPERSAMPLE, 1);

the 1 should be 8. I tried all of them but the program always stops at the same point. any more suggestions? Please help!

I attach the code here.
thank you again

struct gen
{
unsigned char ** data;
unsigned short int width;
unsigned short int height;
unsigned short int bits_per_pixel;
};

struct gen imagen;

TIFF *out= TIFFOpen("ar.tif", "w");

TIFFSetField (out, TIFFTAG_IMAGEWIDTH, imagen->width); TIFFSetField(out, TIFFTAG_IMAGELENGTH, imagen->height);

TIFFSetField(out, TIFFTAG_SAMPLESPERPIXEL, 1);

TIFFSetField(out, TIFFTAG_BITSPERSAMPLE, 1);

TIFFSetField(out, TIFFTAG_ORIENTATION, ORIENTATION_TOPLEFT);

TIFFSetField(out, TIFFTAG_PLANARCONFIG, PLANARCONFIG_CONTIG);

TIFFSetField(out, TIFFTAG_PHOTOMETRIC, PHOTOMETRIC_MINISBLACK); BYTE *bits;

for (int y = 0; y < imagen->height; y++)
{

bits= imagen->data[y*imagen->width];

if (TIFFWriteScanline(out,bits, y, 0)==-1) cout<<"Complete or error";
}
