Vietnamese complex-script support?
Hi, Are there plans to add complex script support for Vietnamese to FOP? Thanks, Jonathan Levinson Senior Software Developer InterSystems
Re: Vietnamese complex-script support?
Hi, I'm not sure there is a specific script for Vietnamese. IIUC, this can be written either with latin script, or with a chinese subset script. Both Latin ans Chinese scripts are handled correctly with Fop, without complex script feature. You should just feed FOP with an appropriate font.

I’ll let Jonathan clarify exactly what he meant, but Vietnamese is typically written in the Latin script with a *lot* of combining diacritics. A naïve implementation can result in very ugly characters; some sophistication is needed to stack multiple combining characters correctly. ~Chris -- Chris Maden, text nerd URL: http://crism.maden.org/ “Peace has other governments that don’t go through the will of politicians.” — Mia Couto, “Rain, the Dreamsend” (tr.

Re: Complex Script Support
I am pleased to let you know that Glenn Adams updated his work with a new patch. This patch includes the following: * bug fixes * new layout engine tests for right-to-left writing mode * new test utility for using TTX files in testing advanced typographic tables * new test cases for GDEF/GSUB/GPOS advanced typographic tables * new test cases for ~85000 arabic word forms against four fonts * new implementation of number formatter for number to string conversion, which adds support for arabic, hebrew, thai, and kana scripts See milestone Patch 5 at http://skynav.trac.cvsdude.com/fop/report/6 for further details. The update has been imported into FOP's code in the Temp_ComplexScripts branch. The new code is available at the URLs cited below. With this patch, Complex Script Support for FOP now supports * Arabic, Hebrew, and Devanagari Scripts * PDF output format Support for * additional scripts * additional output formats remains to be done. The current state of complex scripts support has been proposed for merger into the main development trunk, subject to appropriate evaluation and verification by the FOP community. You can download the binary distribution or the fop jar file from http://people.apache.org/~spepping/. You can check out the source code from FOP's subversion repository, http://svn.apache.org/repos/asf/xmlgraphics/fop/branches/Temp_ComplexScripts.

Re: When will complex script support be available?
I'm targeting the end of this month (October) to complete a final patch adding new test suite material, and request the temporary complex script branch be merged into the trunk. Merging into the trunk will require consensus by the project's PMC, so we'll see how that goes. In the mean time, I'll take a look at your report about a loop/hanging problem. As far as my tests go, Arabic ant RTL text is being handled properly in tables and elsewhere. Active issues are being tracked at http://skynav.trac.cvsdude.com/fop/report/1. Regarding font support, see: http://skynav.trac.cvsdude.com/fop/wiki/SupportedFonts Although Arial Unicode MS is known to work, it is the worst quality of the fonts listed as being supported, and also requires the most memory and resources (and processing time) due to its large number of glyphs (50,377) and large number of OTF tables.

Complex Script Support
I have just downloaded the latest binary dt. 15.06.2011 and performed a small test for indic fonts, namely Bengali and find that there has been no change from the fop 1.0 stable build. I enclose a samle pdf to explain my finding. Indic fonts require combination of 2 or more characters to produce the complex character. In the stable build as well as this, this combination is not occurring and the characters are printed as individual entities. I am not sure if this additional information will be of any help, but as a flash developer I face a similar problem in flash whenever I try to embed the font. The problem in flash does not occur if I use the system device fonts. The TTF font I am testing with is called 'Shonar Bangla'. I tried to test if the font would show correctly without embedding by referencing the font in the configuration file as fonts referenced-fonts match font-family=Shonar Bangla/ /referenced-fonts /fonts However, this somehow is failing with a message Warning: Font Shonar Bangla, normal, 400 not found. Substituting with any,normal,400 and then it tries to find the glyphs using Times-Roman The text in the pdf should have looked like this. প্রথম পাতা| দিব্যি ঘুমাচ্ছিলাম আমি আর ইচ্ছামতী। Thank you, Kind Regards Rajat Narain India test.pdf Description: Adobe PDF document - To unsubscribe, e-mail: fop-users-unsubscr...@xmlgraphics.apache.org For additional commands, e-mail: fop-users-h...@xmlgraphics.apache.org
Re: Complex Script Support
Hi Rajat, That error message means that FOP can't find the font you're referencing. You can either put the font into your systems font directory (which depends on which OS you're using), or you can check http://xmlgraphics.apache.org/fop/trunk/fonts.html which will describe how to manually configure fonts. Also, check the archives, there have been plenty of people struggling with this issue, you'll probably find answers to many of your questions there.

Complex Script Support
Dear, I am Imad Daou and I have been using FOP from about 1 year and I was satisfied from it's results until I tried it with Arabic which is my native language. I searched and found that you are working on it and found that you did good progress in PDF renderer where arabic letters are displayed correctly. Can you please tell me when this will be working on the PrintRenderer (Post Script) since I am using FOP to directly print data without using PDF converter. Waiting your reply, Imad
Re: Complex Script Support
Imad, Thank you for you query. I am happy you are interested in Arabic support. I am unable to respond regarding a schedule for Postscript support. My first priority is to support PDF output, and there are a few things to accomplish before I can say that PDF is adequately supported. After that it will depend on what I can do to add Postscript support. Hopefully, it will not require too much additional work, since most of the functionality for the new Arabic support comes before the intermediate format rendering. I will update this list (and you) when I have added the necessary support for the Postscript renderer (and other renderers).

Re: Complex Script Support
Thanks to Simon for committing this patch. Let me provide some additional information that will help evaluators or reviewers: - this work is being developed in the Temp_ComplexScripts branch of the FOP SVN repository, and, when appropriate, will be merged into the main development trunk; however, that will not occur until the new features in this branch are completed, new test suites are created and verified, and sufficient time has passed to ensure appropriate evaluation and verification by the FOP community; - the present state of this work is PRE-ALPHA; as such, it is not yet feature complete; therefore, anyone attempting to use this work should expect to find incomplete or incorrect results as well as programming errors resulting in abnormal termination, etc; so, caveat emptor please! - some preliminary documentation of this work is available at https://skynav.trac.cvsdude.com/fop/wiki; as work progresses, this documentation will be better organized and transferred to the FOP Wiki and Documentation pages; - during the development of this branch, known issues on this work are being tracked at https://skynav.trac.cvsdude.com/fop/report; after this branch is merged into the development trunk, new bugs and issues will be tracked in the Apache bugzilla database; - initial support is focused on Arabic script support, which entails the support of complex character to glyph mapping (sometimes referred to as 'glyph shape selection' or 'glyph substitution') and bidirectional processing; - currently supported fonts (that I have tested to some extent, but not completely) are documented at https://skynav.trac.cvsdude.com/fop/wiki/SupportedFonts; this list will be expanded over time; - no use is made of external libraries or platform specific libraries; e.g., ICU4J is not used; the platform fonts are used directly to provide advanced typographic table support (about which see https://skynav.trac.cvsdude.com/fop/wiki/ComplexScriptFeatures); - no testing on output renderers other than PDF and AT (XML area tree) has taken place yet; so please restrict your usage to PDF in the near term; Now, here are some additional useful points to make about current limitations or known issues that apply. Please read the Active Issues report in the above referenced TRAC site for further details: - non-spacing marks are not yet supported, and their use in content will cause noticeable problems; this is the current top priority issue, since support for a number of such NSMs is mandatory even in non-vowelized (non-pointed) Arabic; - use of text-align='justify' does not produce correctly justified lines when Arabic is present; - correct semantic support for writing mode relative corresponding properties is not yet present, and, as a result text-align='right' is not implied for blocks that have a default bidi level of 1 (right to left), so you will need to explicitly add text-align='right' to achieve correct alignment; - support for inline FOs in bidi contexts is presently limited to fo:inline, fo:bidi-override, and fo:character; support for the remaining inline FOs will be added in an upcoming update to this branch; - full testing of bidi level assignment and reordering has not yet occurred, so some errors should be expected; the same applies for arabic shaping rules (i.e., presentation glyph selection); Keeping the above in mind, please do try out this preliminary work and report to me or to this list any issues that you find. When you do find an issue, try to isolate the input FO file to the absolute minimum amount of content that causes the problem. If I have to look through a long input file (and output PDF) for a small problem I am more likely to put that on the bottom of my queue, and not on the top. In other words, if you are going to take the trouble to report something, then please help me out by reducing the problem to its bare minimum form. Furthermore, when posting issues, please provide the output PDF file as well as.

Glenn Adams is developing this functionality on behalf of Basis Technologies. To make this development efficient and successful, we need your contribution as well. Does your native language use complex scripts and perhaps right-to-left writing mode (Arabic, Hebrew, Indic scripts)? Then install this version of FOP and test it with some of your XML or FO files. Report your findings on this mailing list. We will announce updates of this work on this mailing list. You can download the binary distribution or the fop jar file from http://people.apache.org/~spepping/. You can check out the source code from FOP's subversion repository, http://svn.apache.org/repos/asf
