Summary: Please fine-tune glyphs of Tamil numerals and one symbol in Lohit Tamil font https://bugzilla.redhat.com/show_bug.cgi?id=807068 Summary: Please fine-tune glyphs of Tamil numerals and one symbol in Lohit Tamil font Product: Fedora Version: 16 Platform: Unspecified OS/Version: Unspecified Status: NEW Severity: unspecified Priority: unspecified Component: lohit-tamil-fonts AssignedTo: psatpute(a)redhat.com ReportedBy: samjnaa(a)gmail.com QAContact: extras-qa(a)fedoraproject.org CC: fonts-bugs(a)lists.fedoraproject.org, psatpute(a)redhat.com, i18n-bugs(a)lists.fedoraproject.org Classification: Fedora Story Points: --- Type: --- Regression: --- Mount Type: --- Documentation: --- Created attachment 572886 --> https://bugzilla.redhat.com/attachment.cgi?id=572886 TTF of replacement glyphs and attestations for the same Description of problem: The Tamil digits in the Lohit Tamil font are not true to the actual printed glyphs and hence do not look so good even though the rest of the Lohit Tamil font is OTOH exceptionally of good quality. The glyph of one Tamil symbol 0BF6 TAMIL DEBIT SIGN is also not true to the printed glyphs. Version-Release number of selected component (if applicable): 2.5.0 How reproducible: Using Lohit Tamil font, compare glyphs to existing printed glyphs. Actual results: The relative proportions, shapes and lengths of the strokes in some of the glyphs are not according to the actual usage in printing. Some changes were subtle, some were very obvious. Expected results: For maintaining high quality, the above problem should be fixed. Additional info: I have attached a small font with the replacement glyphs. Mostly they are: 1) glyphs copied from elsewhere in the font or another Lohit font (for zero) 2) existing glyphs with positioning of some nodes slightly modified If above not possible, only then I have changed the number of nodes. I have also provided the attestations from printed books. Especially please note that the Tamil zero should be perfectly circular, and the 0BF6 TAMIL DEBIT SIGN should be derived from Tamil PA ப. [In the Unicode chart, the glyph of 0BF6 is wrong and I have asked them to correct it.] Please make sure to autohint the glyphs as due to change in number of points the original hinting information might have been lost. Sorry for that. -- Configure bugmail: https://bugzilla.redhat.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

[Bug 806591] New: SHI SHII glyphs in Lohit Tamil font need to be corrected

In both cases the vowel sign is not correctly positioned over the consonant. Further in SHI the vowel sign does not attach to the consonant at all. Version-Release number of selected component (if applicable): 2.5.0 How reproducible: Use Lohit Tamil font. Steps to Reproduce: 1. Type ஶி ஶீ by selecting Lohit Tamil font. 2. Zoom to large size. 3. Especially note the minute gap between SHA and VS-II. Actual results: You can see that the described problem exists. Expected results: The vowel sign should be correctly positioned w.r.t. the consonant and it should correctly attach to the consonant. Additional info: Currently within the SHI SHII glyph of the Lohit Tamil font the contours for the vowel sign are separate and not unified with the consonant's contours. This causes overlapping nodes which is not recommended. Furthermore the RSB of SHI is zero, which is inappropriate. Compare the RSB values of glyphs of other consonants + VS-I. I have modified the glyphs by taking the position of the vowel signs and the RSB values of PI/PII (PA + VS-I and VS-II) as a model since the right-side contour shape of PA is closest to that of SHA. I have provided glyphs with unified and non-unified contours. Please find it in the attachment. I recommend to use the unified contours and have only given the non-unified contours in case you wish to do any other adjustment of positioning (unlikely). I have also provided attestation for the actual appearance of SHI/SHII as seen in printed books, -- Configure bugmail: https://bugzilla.redhat.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

According to Poppler developers[2], this is because Fedora doesn't include a substitution rule for this font, which can be found at [3]. I could test that adding this rule fixes the problem. So I think tit should be added, together with the Symbol -> Standard Symbols L one.

[Bug 679030] New: [freetype] uneven rendering quality when bytecode is enabled

Summary: [freetype] uneven rendering quality when bytecode is enabled https://bugzilla.redhat.com/show_bug.cgi?id=679030 Summary: [freetype] uneven rendering quality when bytecode is enabled Product: Fedora Version: 15 Platform: Unspecified OS/Version: Unspecified Status: NEW Severity: unspecified Priority: unspecified Component: freetype AssignedTo: mkasik(a)redhat.com ReportedBy: jfrieben(a)hotmail.com QAContact: extras-qa(a)fedoraproject.org CC: behdad(a)fedoraproject.org, kevin(a)tigcc.ticalc.org, fonts-bugs(a)lists.fedoraproject.org, mkasik(a)redhat.com Classification: Fedora Description of problem: After updating to the latest FreeType build for which the bytecode interpreter has been enabled, fonts are rendered with uneven quality. The system font used e.g. for button labels is very thin now and certain popular web fonts (e.g. Verdana) are rendered surprisingly poorly. Look at the four attached screenshots which demonstrate the various combinations for which the bytecode interpreter is enabled (disabled) and webcore fonts are installed (removed). Version-Release number of selected component (if applicable): freetype-2.4.4-3.fc15 How reproducible: Always. Steps to Reproduce: 1. Launch firefox. 2. Open http://www.bbc.co.uk . Actual results: Partially poor rendering depending on whether the bytecode interpreter is enabled or not. Expected results: Acceptable rendering quality throughout all font families. Additional info: Reverting to freetype-2.4.4-2.fc15 restores globally good font rendering. -- Configure bugmail: https://bugzilla.redhat.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
