Bug ID: 1648612 Summary: bad hinting instructions from bug in ttfautohint Product: Fedora Version: 29 Component: lohit-telugu-fonts Assignee: petersen@redhat.com Reporter: htl10@users.sourceforge.net QA Contact: extras-qa@fedoraproject.org CC: extras-qa@fedoraproject.org, fonts-bugs@lists.fedoraproject.org, i18n-bugs@lists.fedoraproject.org, i@cicku.me, petersen@redhat.com, psatpute@redhat.com, yselkowi@redhat.com

Font Validator identifies this to be another font affected by the ttfautohint bug. The affected glyph ID is 796.

Yes it is quite sh*t - "ftview 200 /usr/share/fonts/lohit-telugu/Lohit-Telugu.ttf" , go to glyph id 796, and zoom in and out between 201 ppem and 200 ppem

Version affected: lohit-telugu-fonts-2.5.5-4.fc29.noarch

+++ This bug was initially created as a clone of Bug #1646687 +++

Description of problem:

This was discussed in freetype-devel for much of early October under the thread "rendering issues with xpdf (and other viewers)".

upstream patch (this was applied after 1.8.2) - you will need to push this to all the fonts affected - in particular, lohit-devanagari-fonts-2.95.4-5.fc29.noarch

commit f18b7c859c92111446ca991743dd709e347d0301 (HEAD -> master, origin/master, origin/HEAD) Author: Werner Lemberg wl@gnu.org Date: Sat Oct 6 09:04:35 2018 +0200

tafpgm.c: Fix stem width offset handling in storage area.

Problem reported by Hin-Tak Leung htl10@users.sourceforge.net.

Version-Release number of selected component (if applicable): ttfautohint-1.8.1-4.fc29.x86_64

How reproducible: Always

Steps to Reproduce: 1. "ftview 53 /usr/share/fonts/lohit-devanagari/Lohit-Devanagari.ttf" 2. navigate to glyph idx 472 with F9/F10/F11/F12 3. use up/down arrow key to see that the circular ring of 12 dots disappears and becomes 3 dots, etc.

Actual results: 3 dots and fewer than 12 dots for many sizes below about 60.

Expected results: 12 dots for idx 472 at all sizes.

Additional info: This was discussed on freetype-devel for much of early October under 'rendering issues with xpdf (and other viewers)'
