Hi,
I'm the upstream author.
This appears to be change in behaviour for tifflib and is present in
the original non-Debian sources, eg.
#include <tiffio.h>
#include <stdio.h>
int main(void) {
TIFF *tif;
int i, y;
char buf[100] = "\0";
tif = TIFFOpen("foo.tif", "w");
if (!tif) {
fprintf(stderr, "Cannot create file\n");
return 1;
}
for (i = 0; i < 2; ++i) {
int bytes_pp;
TIFFSetField(tif, TIFFTAG_IMAGEWIDTH, 20);
TIFFSetField(tif, TIFFTAG_IMAGELENGTH, 20);
TIFFSetField(tif, TIFFTAG_SAMPLESPERPIXEL, 3);
TIFFSetField(tif, TIFFTAG_PLANARCONFIG, PLANARCONFIG_CONTIG);
bytes_pp = TIFFScanlineSize(tif);
for (y = 0; y < 20; ++y) {
TIFFWriteScanline(tif, buf, y, 0);
}
TIFFWriteDirectory(tif);
}
TIFFClose(tif);
return 0;
}
gcc -otifdirtest tiffdirtest.c -ltiff
./tiffdirtest
tiffdump foo.tif | grep StripByteCounts
# Etch:
StripByteCounts (279) LONG (4) 1<160>
StripByteCounts (279) LONG (4) 1<160>
# Sid:
StripByteCounts (279) LONG (4) 1<0>
StripByteCounts (279) LONG (4) 1<0>
# original libtiff 3.9.0
(using LD_LIBRARY_PATH=/home/tony/local/tiff/lib ./tiffdirtest with tiffdirtest
builting against an installed tifflib 3.9.0):
StripByteCounts (279) LONG (4) 1<0>
StripByteCounts (279) LONG (4) 1<0>
>From the Imager side of things, the single image function *doesn't*
produce the problem StripByteOffsets - and the only real difference
between that and the multiple image writer is the call to
TIFFWriteDirectory for each image in the multi-image code.
