Lohit Odia 2.91.0 ready for testing under Lohit 2 project

   Started working on this in last month with Shilpa. When initial started working on this script, found it bit difficult. But Odia script is very similar with Devanagari and over the time found comfort with it.

   Shilpa did most of the work and i did verification and fixed few issues. One thing again i noticed during release is using of AFDKO. It is good and we should use AFDKO fully in Lohit project for better quality. Will see if we can do it in long term.

  For now regarding 2.91.0 release. Following are important points:

  • Followed Unicode specifications.
  • Re-writing all GSUB rules.
  • Open type rules are available in .fea file for easy re-usability.
  • Feature file compiled with AFDKO.
  • Supports 'orya' and 'ory2' opentype specifications tag.
  • Developer friendly glyphs names with AGL syntax format.
  • Corrected glyph class for all glyphs. 
  • Improved shape of ka-viramasignodia-taodia.
  • Added Glyph positioning rules for below based matras.
  • Test file available with release tarball.
  • Auto testing support with harfbuzz hb-shape.Tested with Harfbuzz and Uniscribe (W8 and XP)
   Update Lohit project page for information regarding download. During release i found few issues which are noted in TODO file. Will fix them before next release. If you find any issue do report on github. Also note TTF file available on my fedorapeople page.

   I remember in FUEL conference i got some improvement suggestions. Couple of them were related to adding Latin to Odia fonts. Presently dont have resource for same but looking forward to solve it in future.

Typoday 2014 At Pune

    This blog was pending on me from long time.  I got a chance to attend typoday.in 2014 conference At Symbiosis International University, Viman Nagar, Pune  in February. This was the my second conference specifically on typography domain after National workshop on calligraphy and typography in 2007.





    It was great to meet typography domain experts and also students with excellent research on different topics.

    I got a chance to meet Kishor Patil (GIST, CDAC), Achyut Palav, Dave Crossland, Girish Dalvi (IITB),  Adam Twardoch (Fontlab), Sarag Kulkarni, Prof.  Santosh Kshirsagar (Sir J. J. Institute of Applied Art, Mumbai) and Prof. Manohar Desai (Head, Communication Design, Symbiosis Institute of Design).


    We had a good discussion on Devanagari script standardization with Girish Dalvi, Dave and Kishor Patil. There was few improvements suggested in Lohit but as a system default font we cant do certain changes without proper references. Girish pointed out there is already discussion happening At Maharashtra state government and soon something will happen.

    Also Dave shared number of things on his plans for commissioning Devanagari typefaces in coming years. It excited number of typographer around.

    We had expert from Adobe, Fontlab there. There was workshop from Fontlab after the conference specifically for students, i did not attended it due to some other work.

    We also had discussion on Google Noto fonts and Lohit2 project. Overall it was good experience of attending typoday conference.

    There were number of interesting topics but few i noted were "Sensory Experiences in Typography", Matilda A Typeface for Children's with Low Vision. There was number of interesting posters available.

    Looking forward for attending typoday 2015 and learn new things.

Few points of Fedora 21 release party @ TIFR, HBCSE, Mumbai

    Fedora 21 release party was planned in quick time, we can say in one week. Attendees were around 25. Few points regarding the event.

Planning experience for Fedora 21 release party At TIFR, HBCSE, Mumbai

    It was good experience to organize Fedora 21 release party At TIFR. Started this idea November last week by initial discussion with Rahul Bhalerao. Long time we did not had any Fedora release party in India. Fedora 21 Final release declared on 9th Dec 2014. Rahul agreed to be co-organizer for same. Second we started thinking for Venue. First place name came to our mind was TIFR, HBCSE. This is the place where we started our open source contribution in 2004 under the guidance of Dr. Nagarjuna G.

    We started initial email conversion with Dr. Nagarjuna G. we got go ahead response for same but finalizing date was tricky due to ICFOSS, Swatantra (http://icfoss.org/fs2014/) was happening during our planned date (20 Dec). We decided date 21st Dec (Idea was Celebrating Fedora 21 on 21st ☺).

    Got $100 budget from Fedora and also some travel budget for Pune-Mumbai from Red Hat.

    Second things was looking for qualified speakers. Fedora community is really nice. I discussed this with Ambassadors in Pune and Praveen kumar quickly jumped in for help with talk on cloud. Due to some reason Parag was not available during same time. Anish volunteered for Talk on Workstation. Me and Rahul took care for Fedora intro and How to contribute in Fedora. I wrote one blog earlier for speakers introduction.

    We had meeting on 15th Dec At TIFR for planning remaining activities. Created event page on Eventbrite  . This was my first event as an organizer and i was wondering on Sunday relaxing afternoon how many people can actually make it. Surprising 38 ticket got booked on eventbrite, it was really motivating.

    We got Fedora 21 DVD's just in time. Hats off to Siddhesh for helping for it and Rahul for collecting it from Siddhesh. We somehow managed it and made it available on 21st. Got few Fedora stickers from Rupali At Red Hat Pune.

    I placed order At http://monginis.net/. Online interface has less option. But once one place the order online, we can talk with there customer care with reference number. They delivered order on time.

    I would like to thanks Dr. Nagarjuna for allowing us to host release party At TIFR. It almost solved 50% of part. Next to Rahul Bhalerao for doing all things to make it successful release party. Praveen Kumar and Anish for volunteering as a speaker and also all attendees for making this successful

Talked on Lohit2 project AT 38th Internation Unicode Conference (IUC)

Last month (4th Nov) i gave talk AT 38th IUC[1], yes i did. :)

Did not able to attend conference due to traveling issues. Lucky enough got a chance to give presentation over Google Hangout. IUC is full with interesting and fruitful talks. Most of the attendees used to be busy for attending talk and networking with key contributors. Would like to give special thanks to Behdad for helping to setup GHangout session during conference and also Rick McGowan for allowing me to give talk over hangout.

Trust me it was difficult as per IST my talk [2] was schedule early morning at 4:00am. Everything went well and given presentation at IUC 38.

My talk was on Lohit2 project. I took workshop in IUC 36 conference for creating open type fonts for complex script. In that workshop i explained how its tricky to develop OT fonts for complex script due to involvement of technical, designing and linguistic. In this different domain there is fair possibility of standardizing technical stuff related to open type fonts. Its almost repeatative.

In IUC 38 i presented Lohit2. Project which aims to create easy to reuse standard, effective and efficient open type tables. For Lohit things even become easy for reusability since it is under open source license.

IUC is special conference since this is the time when most of the expert in language computing domain come together. I got nice audience for my talk and had interesting Q&A session later.

Thanks Behdad for this snap. Was not able to see early with whom i am talking :)

I ended my talk with the hope of achieving next milestone in making font developers life easy by making just click and import templates for complex script fonts. Then only things left for designer is to design typeface.  My slides are available in slideshare.  [3]

Next releases (2.91.1) of Tamil, Assamese and Bengali available with critical bug fixes.

   We did alpha release of Tamil, Assamese and Bengali earlier. During testing we found following issues.

  • Lohit Tamil was not rendering correctly due to issue with auto hinting with fontforge in font.  [1]
  • Lohit Assamese and Bengali fonts conjucts were breaking with Matras. [2]
    Both critical bugs are resolved in 2.91.1 version.

    Other than this, we did thorough testing of these fonts in Windows XP. Fixed number of rendering issues with XP.
    Few issues still exist [3][4] . These issues are mentioned in README file of specific fonts. Planning to resolve these issues in coming release.

    Font are available to download from fedorahosted. [5]  Need your help for further testing and making it more perfect. Feel free to report issues or provide suggestion at github [6] or mailing list.

    Thanks to Nilamdyuti Goswami, Shantha Kumar, Felix and capellsk for testing and providing input.
