This document describes the changes made to the software between the

<I>previous</I> and <I>current</I> versions (see above). If you don't
|
|
find something listed here, then it was not done in this timeframe, or
|
|
it was not considered important enough to be mentioned. The following

supporting large files on Unix-type systems with a 32-bit 'long'
|

type and a 64-bit 'off_t' type.

|
|
|
|
<UL>
|
|
|
|
<LI> tiffiop.h:
|
|
<UL>
|
|
<LI> Macros added to use 64-bit equivalents for all standard I/O
|
|
and POSIX APIs used by libtiff and its tools which are limited
|
|
to 2GB in Windows builds. Note that these 64-bit equivalents
|
|
were introduced by the CRT provided with Visual Studio 2005 and
|
|
if the necessary CRT is not installed on the target computer,
|
|
the program will not run. The wrapper macros will not be
|
|
activated unless the definition _MSC_VER is at least 1400 or
|
|
__MSVCRT_VERSION__ is at least 0x800.
|
|
</UL>
|
|
|
|
<LI> tif_unix.c:
|
|
<UL>
|
|
<LI> Updated to support large files under Microsoft Windows.
|
|
This makes tif_unix.c a completely viable candidate for use
|
|
under Windows (in spite of its name) if the CRT is modern
|
|
enough. Please note that tif_win32.c already supported large
|
|
files, but only 'tiffinfo' and 'tiffdump' made any provision to
|
|
support large files under Windows.
|
|
<LI> _tiffReadProc() and _tiffWriteProc() are modified to chunk
|
|
I/O to a maximum size of 2GB for extremely large I/O
|
|
requests. This surmounts limitations in the Microsoft Windows
|
|
read() and write() APIs (which are limited to the range of a
|
|
32-bit 'int'), and may avoid poor behavior with extremely large
|
|
I/O requests on other systems.
