You can obtain exactly the same final image quality on both formats, but png will have smaller disk size. Final result only depends on RGB->1 bit indexed conversion method used. AFAIK png decompression is not resource hungry. Compression *IS*. PS For minimal png archive size, you *MUST* convert image to 1 bit indexed palette before saving it.

The problem isn't so much about WikiMedia or OpenMoko, but that the original authors did not free the images. As such, whilst maybe they can be on Wikipedia, which is on a non-profit environment, distributing on the WikiReader (which is for-profit) may be legally problematic. If there's a way to automatically determine if the image is safe to copy (for instance, being licensed with a good CC license like by, by-sa) then it's doable.

Re: [wikireader] Images on the WR not so imposible :P [was [wikireader]Error on parsing the spanish wikipedia]
Regarding compression, I believe lzma is already builded in the wikireader application and it compress the images a 50%. enough for start I guess. but I have to recongnize than the image on png looks really good do maybe it worth the meaning to implemente it on the device if it's not much resource hungry Regarding licensing , well until OM or/and Wikipiedia doesn't say the contrary (for example considering Wikireader as an extension of the Wikipedia and allow all wikipedia image to be on Wikireader) we must stay in the save side so only explicitly free licenced images will be safe to use, I'm working on the http://download.wikimedia.org/enwiki/latest/enwiki-latest-image.sql.gz table to know how many pictures we are talking about. Also some way to not infringe the authoring and licencing text includings clauses must be used by the images viewer. but I guess it can be done by links to text as other wikipage more. Regarding machine needed to do so, due we just need at maximum of 240 pixel with we can tweak the Wikix to use the thumb url like this http://upload.wikimedia.org/wikipedia/commons/thumb/f/f9/HN_Pegasi_B.jpg/240px-HN_Pegasi_B.jpg instead of the full url http://upload.wikimedia.org/wikipedia/commons/f/f9/HN_Pegasi_B.jpg and this will save us a lot disk space and a step in the process :P Also Wikix must be tweaked to just download "free licenced images" using the info on the enwiki-latest-image.sql.gz file then sure we will save a lot more disk space.

That character gets removed in a later build stage. We had to add that because of a integer conversion issue with SQLite. It was automatically converting articles like "1984" into integers (not strings) and storing them in the database. SQLite, BTW, claims this is a "feature".

OK that's fixed now. Chris already checked in the code. Our build

Yeah we're trying exactly that Nelson. It's just a long process to render all this stuff. We actually have 9 quad-core systems running in parallel now.

Re: [wikireader]Error on parsing the spanish wikipedia

We're working on exactly the same thing now :-)
I'll ask Chris to email the list once we get past it. I think the
problem is with the mixtures of different encodings (latin-1 and
UTF-8) in the Spanish Wikipedia and the way our code is handling this.
For some reason Python's print (at times) wants to default to ascii,
even after we explicitly tell it to use UTF-8.

[wikireader]Error on parsing the spanish wikipedia
Hi I'm trying to generate the file for a spainsh wikipedia on the WR ,
after compiling succsesfuly the source on the git and solve some
annoyings with utf8 encoding on phyton error was somthing like this:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in
position: ordinal not in range(128)
this was solved changing the default encode "ascii" to "utf8" int the
/usr/lib/python2.6/site.py file
after this I was hable to execute ok the instruction:
make DESTDIR=image WORKDIR=work
XML_FILES=xml-file-samples/eswiki-latest-pages-articles.xml index
parse render combine
Every thing seem fine for a couple(about 6-7h) of hours parsing the
70 articles in spanish but then ... the horror
Count: 38
Traceback (most recent call last):
File "./ArticleParser.py", line 224, in
main()
File "./ArticleParser.py", line 172, in main
process_article_text(title.encode('utf-8'), f.read(length), newf)

I have relaunched the process again with the (few)hope that was a
temporary fault but If any one has a clue will be helpfull.
BTW.- I documenting all this proccess to make a step by step howto on
how to put the wikipedia in other languages on the wikireader.
