Hello,

I am a new user of libtiff library and I have some doubts. I am developing a program to read a tiff file G3 and I need to clear the last white lines from file, I would like to know what api can I use?

my code:

TIFF *image;
tsize_t stripSize;
unsigned long imageOffset,result;
int stripMax,stripCount;
char *buffer;
unsigned long bufferSize;
uint32 rowsperstrip;
int count;
uint32 width;

// Abre a imagem TIFF.
if((image = TIFFOpen(pathArquivo, "r")) == NULL)
{
 fprintf(stderr, "Could not open incoming image\n");
 return FALSE;
}

// Lê a possibilidade de multiplos strips.
if((stripSize = TIFFStripSize (image)) == -1)
{
 return FALSE;
}

if((stripMax = TIFFNumberOfStrips (image)) == -1)
{
 return FALSE;
}
bufferSize = TIFFNumberOfStrips (image) * stripSize;

if((buffer = (char *) malloc(bufferSize)) == NULL)
{
 fprintf(stderr, "Could not allocate enough memory for the uncompressed image\n");
 return FALSE;
}

imageOffset = 0;
for (stripCount = 0; stripCount < stripMax; stripCount++)
{
 if((result = TIFFReadEncodedStrip (image, stripCount, buffer + imageOffset,stripSize)) == -1)
 {
   fprintf(stderr, "Read error on input strip number %d\n", stripCount);
   return FALSE;
 }
 imageOffset += result;
}
