PDF Documentation
by Dustin Spicuzza 24 Sep '08

Hey, I've noticed that its mentioned in the docs that you can generate PDF documentation via boostbook, however it appears to fail violently when I try. I can build the HTML docs with little effort. Additionally, there are a number of links on the boost website to PDF versions of the docs that no longer exist and give 404 errors. Is PDF still a supported output format for the docs? Thanks.

A compilation problem at function10.hpp in the function library

Hi guys, I cannot compile without error for function10.hpp in Visual Studio 2005 Pro. A simple source file to reproduce the problem is attached(Test.cpp). There is no such problem with other function0-9.hpp, except for function10.hpp. The error message encounter is as below, 1>d:\downloads\boost_1_36_0\boost_1_36_0\boost\mem_fn.hpp(318) : warning C4180: qualifier applied to function type has no meaning;

Re: [Boost-users] XML optional field
by Tan, Tom (Shanghai) 24 Sep '08

I am in the similar need and am trying RapidXml(http://rapidxml.sourceforge.net/) . I am still in the middle of modifying the code to support UTF-16 with wchar_t, as far as I can tell now, it's quite well designed and easy to use, esp. with the utilities wrapping around the core parser. If you are interested in my modifications to UTF-16, leave me a message at rockonedge at gmail. >Date: Tue, 23 Sep 2008 06:56:18 +0000 >From: Emanuele Rocci <rocciemanuele(a)hotmail.com> >Subject: [Boost-users] XML optional field >Hi AllI would like to build a configuration file for my application in XML.The Configuration files includes also optional sectionsi.e. there might be properties that are not required to be defined by the user.

[filesystem] has_branch_path()
by Robert Jones 24 Sep '08

24 Sep '08

I'm upgrading the Boost release in use at work from 1.33.1 to 1.36.0, with surprisingly few issues actually, but I am stuck on one thing. There's a function in 1.33.1, has_branch_path(), for which I cannot see the equivalent functionality in 1.36. Part of my difficulty is that the 1.33.1 header declares but does not define the function, and I cannot see where the body code is! Any suggestions would be appreciated at this point. Thanks. - Rob.

[gil] new io extension
by Christian Henning 23 Sep '08

23 Sep '08

Hi there, I've been busy working on the next version of gil's IO extension. The last iteration was very slow to compile especially when reading or writing tiff images. This and other problems have been fixed. As a result compilation is a lot faster but also a lot more tiff formats can now be read or written. Please grab the latest from: http://gil-contributions.googlecode.com/svn/trunk/gil_2/boost/gil/extension… This download is a little bigger than to usual since there are test images included. Please see my original announcement below for documentation. The goal of this extension is to substitute the original io lib which is part of gil, and though shipped with boost. To do this a review is probably needed. I'll work on a proper documentation as the next step. Can anyone tell me where to find a tutorial for creating quickdoc? There is one problem I cannot fix and would like to ask the experts on this list. Please read the readme.txt in libs\gil\io_new\unit_test which explains the scenario. This problem has something to do with erroneously choosing the wrong functions by the compiler. The enable_if metafunction doesn't work correctly here. As usual any feedback is welcome. Thanks, Christian ------------------------------------------------------- Hi there, over the past few months I have been working on a new version of gil's io extension. In this release I've added support for: * more image formats, most importantly bit_aligned images ( like 1bit images ), * reading of subimages like one row at a time for huge images, * reading image information, only. * having a unified interface for all sorts of devices, subimages, and converter objects. So far, png, jpeg, and tiff images are supported. In the not so distant future there will be bmp and pnm images added. You can grab the current version via subversion from: https://gil-contributions.googlecode.com/svn/trunk/gil_2/boost/gil/extensio… If desired I can supply a zip file to the vault. The images libraries can be grabbed from: ftp://ftp.uu.net/graphics/jpeg/jpegsrc.v6b.tar.gz ( www.ijg.org isn't responding ) http://www.libpng.org/pub/png/libpng.html http://www.libtiff.org/ It's highly advised to built your own version of the image lib you need. I installed the GNU's binaries for Windows, but unfortunately, I only had problems with them. The library is still header-only. When using boost::filesystem's paths, of course, you add a dependency to the filesystem lib. The Read Interface ------------------------ Reading an image can be done in multiple ways depending on what your need is. Like the old io lib there are 4 different ways of reading images. As there are: * read_image: Read image, the right amount of memory will be allocated beforehand. The supplied image type needs to be compatible with actual image file. * read_view: Read image, the image's memory must be already allocated. The supplied image type needs to be compatible with actual image file. * read_and_convert_image: Same as read_image, but the user can specify an color converter. * read_and_convert_view: Same as read_view, but the user can specify an color converter. There is a new function for reading image information. Since every image format has it's own set of tags, the library defines seperate image_read_info<format_tag> structures. Please see, for instance, the jpeg_tags.hpp header. As for the function parameters the following sections in the same order. 1. String for file name ( std::string, std::wstring, char*, boost::filesystem::path ) OR devices ( FILE*, TIFF*, std::ifstream ) 2. Image or view type 3. Optional: Subimage definition ( top_left corner + dimensions ) 4. Optional: Color converter. This parameter is only valid for converting functions. The default parameter is gil's default_color_converter 5. Format Tag. Reading the image information only takes parameter 1 and 5. Here are some examples for reading images: #include <boost/gil/extension/io_new/jpeg_read.hpp> // Read image information std::string filename( "..\\test_images\\jpg\\found online\\test.jpg" ); image_read_info< jpeg_tag > info = read_image_info( filename, tag_t() ); // Read image FILE* file = fopen( filename.c_str(), "rb" ); rgb8_image_t img; read_image( file, img, tag_t() ); // Read image ifstream in( filename.c_str(), ios::in | ios::binary ); rgb8_image_t img( 136, 98 ); read_view( in, view( img ), tag_t() ); // Read and convert image, use gil's default converter. rgb8_image_t img; read_and_convert_image( filename, img, tag_t() ); // Read a 10x10 subimage, starting from the top_left corner. rgb8_image_t img; read_image( filename, img, point_t( 0,0 ), point_t( 10, 10 ), tag_t() ); I have created some header files to support the old read interface. For example: #include <boost/gil/extension/io_new/jpeg_io_old.hpp> std::string filename( "..\\test_images\\jpg\\found online\\test.jpg" ); rgb8_image_t img( 136, 98 ); jpeg_read_view( filename, view( img ) ); The Write Interface --------------------------- The write interface is a much simpler than the read interface. Here, we only have write_view as the entry point. As for parameters the following sections are supported: 1. String for file name ( std::string, std::wstring, char*, boost::filesystem::path ) or devices ( FILE*, TIFF*, std::ofstream ) 2. View type 3. Optional: image_write_info< FormatTag > 4. Format type The image_write_info<...> structure defines a format specific properties which can be used when writing an image. A good example is jpeg's image quality value. Examples: #include <boost/gil/extension/io_new/tiff_write.hpp> // Write image string filename( "..\\test\\tiff\\test1.tif" ); gray8_image_t img( 320, 240 ); write_view( filename, view( img ), tiff_tag() ); // Write image string filename( "..\\test\\tiff\\test2.tif" ); TIFF* file = TIFFOpen( filename.c_str(), "w" ); rgb8_image_t img( 320, 240 ); write_view( file, view( img ), tag_t() ); I have created some header files to support the old write interface. For example: #include <boost/gil/extension/io_new/tiff_io_old.hpp> string filename( "..\\test\\tiff\\test3.tif" ); gray8_image_t img( 320, 240 ); tiff_write_view( filename, view( img ) ); The primary goal of this new version is to eventually replace the old io library which is part of boost's distribution. Do I need to apply for a review? I'm not sure how to go from here. I know there is still some work to do before a possible review. Documentation is lacking and support for dynamic image needs to be added. But what I want for now is to get some feedback on design and implementation. I would like to thank Lubomir Bourdev and Andreas Pokorny for their most valueable input. Thanks, Christian

[boost] File_lock bad compilation - 1.35.0
by Germain BARRET 23 Sep '08

23 Sep '08

I'm actually using boost 1.35.0 When I just include boost/interprocess/sync/file_lock.hpp in a very simple programm, then I have a list of error very surprising : "member function already defined or declared" So what, is file_lock unusable in 1.35 ? It was my only hope, other boost locks don't satisfy me. I didn't see such an error in the last 6 month ML log, so I guess nobody had it yet. log : 1>c:\boost_tri\include\boost-1_35\boost\interprocess\sync\file_lock.hpp(167) : error C2535: 'bool boost::interprocess::file_lock::timed_acquire_file_lock(boost::interprocess::file_handle_t,bool &,const boost::posix_time::ptime &)' : member function already defined or declared 1> c:\boost_tri\include\boost-1_35\boost\interprocess\sync\file_lock.hpp(110) : see declaration of 'boost::interprocess::file_lock::timed_acquire_file_lock' 1>c:\boost_tri\include\boost-1_35\boost\interprocess\sync\file_lock.hpp(195) : error C2535: 'bool boost::interprocess::file_lock::timed_acquire_file_lock_sharable(boost::interprocess::file_handle_t,bool &,const boost::posix_time::ptime &)' : member function already defined or declared 1> c:\boost_tri\include\boost-1_35\boost\interprocess\sync\file_lock.hpp(138) : see declaration of 'boost::interprocess::file_lock::timed_acquire_file_lock_sharable' 1>c:\boost_tri\include\boost-1_35\boost\interprocess\sync\file_lock.hpp(119) : error C3861: 'try_acquire_file_lock': identifier not found 1>c:\boost_tri\include\boost-1_35\boost\interprocess\sync\file_lock.hpp(147) : error C3861: 'try_acquire_file_lock_sharable': identifier not found 1>c:\boost_tri\include\boost-1_35\boost\interprocess\sync\file_lock.hpp(175) : error C3861: 'try_acquire_file_lock': identifier not found 1>c:\boost_tri\include\boost-1_35\boost\interprocess\sync\file_lock.hpp(188) : error C3861: 'sleep': identifier not found 1>c:\boost_tri\include\boost-1_35\boost\interprocess\sync\file_lock.hpp(203) : error C3861: 'try_acquire_file_lock_sharable': identifier not found 1>c:\boost_tri\include\boost-1_35\boost\interprocess\sync\file_lock.hpp(262) : error C2039: 'timed_acquire_file_lock' : is not a member of 'boost::interprocess::detail' 1>c:\boost_tri\include\boost-1_35\boost\interprocess\sync\file_lock.hpp(298) : error C2039: 'timed_acquire_file_lock_sharable' : is not a member of 'boost::interprocess::detail'

functors with function_traits
by Christoph 23 Sep '08

23 Sep '08

Do function_traits work with functors? I tried with struct XYZ { bool operator() (int x) const { return x+2; } }; template<typename FUNCTION> class BindingImpl1xxx { public: typedef FUNCTION function; typedef typename boost::function_traits<FUNCTION>::result_type res_type; typedef typename boost::function_traits<FUNCTION>::arg1_type arg1_type; }; but the following won't compile: XYZ xyz; BindingImpl1xxx<XYZ> xxx(xyz); Is there a way to achieve the function_traits functionality with function_traits or some other type_traits? Thank you. Christoph
