OpenType layout (OTL)OpenType layout features were introduced in mPDF ≥ 6.0 Advanced TypographyMany TrueType fonts contain OpenType Layout (OTL) tables. These Advanced Typographic tables contain additionalinformation that extend the capabilities of the fonts to support high-quality international typography:.

OTL fonts support ligatures, positional forms, alternates, and other substitutions. OTL fonts include information to support features for two-dimensional positioning and glyph attachment. OTL fonts contain explicit script and language information, so a text-processing application can adjust its behavior accordingly.mPDF 6 introduces the power and flexibility of the OpenType Layout font model into PDF. MPDF supports GSUB, GPOSand GDEF tables for now.

MPDF does not support BASE and JSTF at present.Other mPDF features to enhance complex scripts:. Bidirectional (Bidi) algorithm for right-to-left (RTL) text. support for Kashida for justification of arabic scripts. partial support for CSS3 optional font features e.g. Font-feature-settings, font-variant. improved “autofont” capability to select fonts automatically for any script.

support for CSS:lang selector. dictionary-based line-breaking for Lao, Thai and Khmer (U+200B is also supported). separate algorithm for Tibetan line-breaking. Note: There are other smart-font technologies around to deal with complex scripts, namelyGraphite fonts (SIL International) and Apple Advanced Typography (AAT by Apple/Mac). MPDF 6 does not support these. 'dejavusanscondensed' = array ( 'R' = 'DejaVuSansCondensed.ttf', 'B' = 'DejaVuSansCondensed-Bold.ttf', 'I' = 'DejaVuSansCondensed-Oblique.ttf', 'BI' = 'DejaVuSansCondensed-BoldOblique.ttf', 'useOTL' = 0xFF, 'useKashida' = 75, ), useOTLuseOTL should be set to an integer between 0 and 255. Each bit will enable OTL features for a different group of scripts: BitdechexEnabled110x01GSUB/GPOS - Latin script220x02GSUB/GPOS - Cyrillic script340x04GSUB/GPOS - Greek script480x08GSUB/GPOS - CJK scripts (excluding Hangul-Jamo)5160x10(Reserved)6320x20(Reserved)7640x40(Reserved)81280x80GSUB/GPOS - All other scripts (including all RTL scripts, complex scripts etc)Setting useOTL to 0 (or omitting it) will disable all OTL features.

Setting useOTL to 255 or 0xFF will enable OTLfor all scripts. Setting useOTL to 0x82 will enable OTL features for Cyrillic and complex scripts.In a font like Free Serif, it may be useful to enable OTL features for complex scripts, but disable OTL for Latinscripts (to save processing time). However, see above - this may disable kerning in Latin scripts in certaincircumstances. UseKashidauseKashida should be set for arabic fonts if you wish to enable text justification using kashida.

The value shouldbe an integer between 0 and 100 and represents the percentage of additional space required to justify the text on aline as a ratio of kashida/inter-word spacing. Choosing fonts to add to mPDF 6Fonts with OTL need to have GDEF, GSUB and GPOS tables in the font file. Although TrueType font files are binaryfiles, the table names and script/feature tags are written as ASCII characters; open the.ttf or.otf file in a texteditor such as Windows Notepad, and you will see GDEF, GSUB and GPOS in the first few lines if they are present. Youcan also search the file to see if the script tags are present for your desired scripts cf.Note: The OTL specification for Indic fonts was updated in 2005 to version 2.

The v2 script tag for Bengali is“bng2” whereas prior to this it was “beng”. Many open-source font files are still written for the old specification.This is supported by mPDF, although v2 fonts give better results.Note: mPDF does not support Graphite or AAT font features. Configuring new fonts for mPDF 6To add a font, first copy the font file to your fontDir directory.Then set fontdatato add the font. See the manual for details if you are not already familiar with this.

Setting OTL use at runtimemPDF caches some font information in the directory configured as tempDir to improve performance.This is regenerated if you change the value of useOTL for a font.There may be circumstances when you wish to use OTL features with different scripts depending on the document e.g.for everyday use you may want to disable OTL for FreeSerif to save processing time, but on occasions use OTL forIndic and/or Arabic scripts. The recommended way to do this is to create 2 instances of the font e.g.
