Adventures with Computers
Mikkel and I have been studying for our first exam in DAIMI:dSoegOpt, he will be having his exam today (good luck!) and I will have mine on Thursday. Reading up on the stuff went surpricingly well — I was afraid that it would be really hard considering that I have made way too few exercises during the semester. The exercises were simply too difficult, but when the exam is oral then making the exercises doesn’t really matter — I hope! :-)
That’s all for now.
The latest version of PEL sports support for TIFF images and lots of other improvements. Read the announcement below, and go to the project page to download it.
Support was added for parsing TIFF images, leading to a mass renaming of files and classes to cleanup the class hierarchy. The decoding of EXIF data is now tested against known values (over 400 individual tests), this lead to the discovery of a couple of subtle bugs. The documentation has been updated and expanded.
Renamed all files and classes so that only EXIF specific code is labeled with Exif. So, for example, PelExifIfd is now PelIfd, since the IFD structure isn’t specific to EXIF but rather to TIFF images. The same applies to the former PelExifEntry* classes.
Fixed offset bug in PelDataWindow::getBytes() which caused the method to return too much data.
Added support for the SCENE_TYPE tag.
Fixed display of integer version numbers. Version “x.0″ would be
displayed as just version “x” before.
Unit tests for EXIF decoding. PEL is now tested with an image from a Sony DSC V1 and one from a Canon IXUS II.
Changed all occurrences of include_once() to require_once() since
the files are indeed required.
Updated documentation all over.
The PHP EXIF Library (PEL) is getting better and better, and version 0.2 was released today — go grab it if you want to play with it.
This release brings updated documentation and better support for the EXIF user comment tag and tags containing version information. The code is now tested using SimpleTest.
All PelExifEntry descendant classes now use setValue() and
getValue() methods consistently.
Signed and unsigned numbers (bytes, shorts, longs, and rationals) are now handled correctly.
The SimpleTest (http://sf.net/projects/simpletest) framework is used for regression testing.
Added new PelExifEntryUserComment class to better support the EXIF user comment tag.
Added new PelExifEntryVersion class to support the EXIF tags with
version information, namely the EXIF_VERSION, FLASH_PIX_VERSION, and
INTEROPERABILITY_VERSION tags.
Updated doc comments all over.
Even
though I’m not particularly royal-minded I cannot help writing a little
something about the wedding between Mary Donaldson and the
Danish Crown Prince Frederik today in Copenhagen. The wedding will be
today at 16:00.
I was up early (7:00) to put up the Danish flag “Dannebrog” at Skejbygård, and in doing so I noticed how many other flags there were up. I counted 31 flags in just the near surroundings of Skejbygård!
We’ll have a special bar later today at Skejbygård, and tonight there will be dinner at the basement — at the same time as the royals will have their dinner. I’m looking forward to it, even though I still don’t know what we’ll be eating :-)
While Mary and Frederik will enjoy their first weeks of being Crown Princess and Prince of Denmark, I’ll be studying for my exmas… But I wish them well anyway!
Although SourceForge is slow with their updates of the statistics on the PEL project pages, I hope a few people have taken the oppotunity to download it. And accourding to the Freshmeat PEL page, then there has indeed been several hundred visits to either the PEL homepage or one of the files available at SourceForge for download.
I realize that PEL will have a limited audience the first few months, since it’s written in the yet-to-be-released version 5 of the PHP. This version is greatly improved, and I can only encourage people to download it right away and start playing with it — and why not use PEL which uses a lot of new PHP5 features. Go download PEL and play!
