Dear All, Today, I announced we are close to the end of the review: http://lists.boost.org/boost-announce/2010/12/0275.php Later on, Christian asked for extension of the review. The Review Wizards agreed and suggested to extend the review until Friday, December 17th, 2010 So, I'm happy to announce that the new cut-off date of the reviews submission is December 17th. Let's say Midnight, UTC Time. Thanks to all reviewers who submitted their comments, to the Review Wizards for the extension and we are hoping to receive more feedback from the reviewers.

Dear All,

The formal review of the IO and Toolbox extensions terminates tomorrow. I'd like to set the cut-off time at Midnight on Saturday, 11 December 2010, UTC Time

I think we have been doing well and received decent amount of feedback. However, anyone feels there is a need for extension, please let me know as soon as possible, so I will have time to negotiate it with the Review Wizards.

Dear All,

According to the Boost Formal Review Schedule [1], review of Christian Henning's extensions to the Boost Generic Image Library (Boost.GIL, [2]), it is: * Boost.GIL.IO * Boost.GIL.Toolbox starts on December 1st and lasts until December 10th, 2010.

=========== What is it? ===========

The Boost.GIL.IO extension provides an easy to use interface for reading and writing various image formats. It also includes a framework for adding new formats. The Boost.GIL.IO is indent to replace the current IO extension which is part of Boost for several years now.

Features:

* A unified way to read and write image encoded in BMP, JPEG, PNG, PNM, and TIFF formats. The capabilities to read and write in various formats have improved dramatically.

* Image data can be provided via standard file or string streams

The Boost.GIL.Toolbox provides new color spaces and other small code to ease programming with Boost.GIL.

Features:

* Implementation of color spaces: Gray_Alpha, HSL, HSV, LAB, and XYZ * Utilities to support dynamic image workflows and color conversions. * Collection of metafunctions to determine alignment, similarity and homogeneity at pixel level.

The Boost.GIL as well as the proposed extensions are provided in form of a headers-only library Although, some image formats come with their format dependency, it is corresponding third-party libraries:

JPEG - libjpeg PNG - libpng TIFF - libtiff

=================== Getting the library ===================

The latest version of both extensions can be downloaded as Zip package:

http://gil-contributions.googlecode.com/files/boost_review.zip

or directly from the Subversion repository:

http://code.google.com/p/gil-contributions/source/browse/trunk/gil_2/

and the docs can built as usual with bjam and quickbook tools

...

from within libs/gil/io_new/doc directory

The libs/gil/io_new/test/readme.txt provides a step by step guide to configuring, building and running the unit tests.

The boost_review.zip is about 20MB due to its extensive collection of test images. They are part of the test suite to make sure that different variations of each image format is read and written correctly.

Please, be aware no guarantee can be given that all formats in their all variants are completely supported.

================ Writing a review ================

If you feel the new IO and Toolbox are interesting extensions to the Boost.GIL library, then please submit your review to the developer list (preferably), or to the review manager (mateusz at loskot dot _n_e_t_)

Here are some questions you might want to answer in your review:

- What is your evaluation of the design? - What is your evaluation of the implementation? - What is your evaluation of the documentation? - What is your evaluation of the potential usefulness of the extensions? - Did you try to use the extensions? With what compiler? Did you have any problems? - How much effort did you put into your evaluation? A glance? A quick - reading? In-depth study? - Are you knowledgeable about the problem domain?

And finally, every review should answer this question:

- Do you think the extensions should be accepted as a part of Boost.GIL library?

Be sure to say this explicitly so that your other comments don't obscure your overall opinion.
