晋太元中，武陵人捕鱼为业。缘溪行，忘路之远近。忽逢桃花林，夹岸数百步，中无杂树，芳草鲜美，落英缤纷。渔人甚异之，复前行，欲穷其林。 　　林尽水源，便得一山，山有小口，仿佛若有光。便舍船，从口入。初极狭，才通人。复行数十步，豁然开朗。土地平旷，屋舍俨然，有良田、美池、桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。 　　见渔人，乃大惊，问所从来。具答之。便要还家，设酒杀鸡作食。村中闻有此人，咸来问讯。自云先世避秦时乱，率妻子邑人来此绝境，不复出焉，遂与外人间隔。问今是何世，乃不知有汉，无论魏晋。此人一一为具言所闻，皆叹惋。余人各复延至其家，皆出酒食。停数日，辞去。此中人语云：“不足为外人道也。”(间隔 一作：隔绝) 　　既出，得其船，便扶向路，处处志之。及郡下，诣太守，说如此。太守即遣人随其往，寻向所志，遂迷，不复得路。 　　南阳刘子骥，高尚士也，闻之，欣然规往。未果，寻病终。后遂无问津者。 .

ABOUT THE OPENEXR LIBRARIES
----------------------------

IlmImf is our "EXR" file format for storing 16-bit FP images.  Libraries in
this package depend on the IlmBase library.

See the IlmImfExamples directory for some code that demonstrates how
to use the IlmImf library to read and write OpenEXR files.  The doc
directory contains some high-level documentation and history about the
OpenEXR format.

If you have questions about using the OpenEXR libraries, you may want
to join our developer mailing list.  See http://www.openexr.com for
details.


LICENSE
-------

The OpenEXR source code distribution is free software.  See the file
named COPYING (included in this distribution) for details.


BUILDING OPENEXR
----------------

Building OpenEXR requires the IlmBase and the zlib library.

You can obtain the source code for zlib from:

   http://www.zlib.net

If you're building OpenEXR on a Windows platform, see README.win32 for
instructions on how to build OpenEXR.  The remainder of this file
applies only to GNU/Linux or other UNIX-like systems.

After installing the required libraries, to build OpenEXR on
GNU/Linux or other UNIX-like systems, do this:

./configure
make
make install

unless you obtained IlmBase directly from git, in which case you
should first read README.git


Please type :

./configure --help

for a list of options in relation to building IlmBase libraries. In 
particular, peruse README.namespaces for information regarding the 
use of namespaces in IlmBase and OpenEXR.

See README.OSX for details on building OpenEXR in MacOS X.

Do `make check` to run the OpenEXR confidence tests.  They should all
pass; if you find a test that does not pass on your system, please let
us know.

Other UNIX variants haven't been tested, but should be easy to build.
Let us know if you're having problems porting OpenEXR to a particular
platform.

All include files needed to use the OpenEXR libraries are installed in the 
OpenEXR subdirectory of the install prefix, e.g. /usr/local/include/OpenEXR.


USING OPENEXR IN YOUR APPLICATIONS
----------------------------------

On systems with support for pkg-config, use `pkg-config --cflags
OpenEXR` for the C++ flags required to compile against OpenEXR
headers; and `pkg-config --libs OpenEXR` for the linker flags required
to link against OpenEXR libraries.
