Good morning all,

The problem concerning the error on the instruction TIFFClose: First-Chance exception in test.exe (NTDLL.DLL): 0x0000008: Invalid Handle is resolved.
To resolve the problem, I installed tiff version 3.8. I had the 3.7.4

But now, it's new problem that I did not have before (maybe i must create a new topic :/)

I have a memory leak when i create several tiff files.

I made a simple test: I open, write and close several tiff files and i see in the task manager of windows that the memory increases 4Kb for every new files.

---------------------------------------------------------------

unsigned char page_portrait_fine[2290][216];

void Pause(){
     cout<<"Push a key to resume ..."<<endl;
     getch();
}

void main(){
        char nom[20];

TIFF *in;

    for(int i=0;i<=10000;i++){

            sprintf(nom,"test_%d.001",i);
            in = OpenTiff(nom);
            CreateHeader(in);
            TIFFWriteEncodedStrip(in,0,page_portrait_fine,216*2290);
            CloseTiff(in);
            Pause();

        }

}

// Open TIFF File
TIFF* OpenTiff(char file[NOM]){
     TIFF *out;
     if((out = TIFFOpen(file, "wl")) == NULL){
             return NULL;
     }
     return(out);
}

// Close TIFF file
void CloseTiff(TIFF* file){
    TIFFClose(file);
}

void CreateHeader(TIFF *out){
    // We need to set some values for basic tags before we can add any data
    TIFFSetField(out, TIFFTAG_IMAGEWIDTH, 1728);
    TIFFSetField(out, TIFFTAG_IMAGELENGTH, 2290);
    TIFFSetField(out, TIFFTAG_BITSPERSAMPLE, 1);
    TIFFSetField(out, TIFFTAG_SAMPLESPERPIXEL, 1);
    TIFFSetField(out, TIFFTAG_ROWSPERSTRIP, 2290);
    //Méthode de compression

TIFFSetField(out, TIFFTAG_COMPRESSION, COMPRESSION_CCITTFAX3);

TIFFSetField(out, TIFFTAG_PHOTOMETRIC, PHOTOMETRIC_MINISWHITE);

// Ordre des bits inversé

TIFFSetField(out, TIFFTAG_FILLORDER, FILLORDER_LSB2MSB);

TIFFSetField(out, TIFFTAG_PLANARCONFIG, PLANARCONFIG_CONTIG);

TIFFSetField(out, TIFFTAG_XRESOLUTION, 204.0);

TIFFSetField(out, TIFFTAG_YRESOLUTION, 196.0);

TIFFSetField(out, TIFFTAG_RESOLUTIONUNIT, RESUNIT_INCH);

}

---------------------------------------------------------------

i don't know if it's a bug...

PS: to update libtiff to the 3.8, i just replace:

• libtiff.lib in "C:\Program Files\Microsoft Visual Studio\VC98\Lib"
• tiffvers.h

  tiff.h
  tiffconf.h
  tiffio.h
  in "C:\Program Files\Microsoft Visual Studio\VC98\include"
- and add dll depedencies in System32 directory

Thanks for your help :)
