Please note that as of this Friday I will no longer be working at
Geoquip. Any e-mail directed to [EMAIL PROTECTED]
on matters concerning FOP is unlikely to get any meaningful
response. Hopefully I will still get the chance to continue working
on FOP and I intend to take another look at the memory usage patches
asap,

Regards,

Richard

  I'm in the process of looking at your patch right now. I suppose  
  you've already seen the additional comment on the bug (?)

Yes. I'll take another look asap,

Thanks for updating the documentation as well as your time.

My issue is, that I do +*not*+ want to use *SFArabic* at all (it is just a 
system font, which is available by default on an MacOS 12.3 and cannot be 
deleted), which is detected during auto scanning by fop.
So I am not quite sure, if specifying the specific font will help with the 
original issue which occurs during auto-scanning.

Is there a configuration option to exclude fonts from being scanned?

The good news: I was able to reproduce it on my Ubuntu 20.04 LTS machine by 
adjusting your code snippet as follows. 

Note: I installed the *SFArabic.ttf* system-wide and re-generated the Ubuntu 
font cache.

*The good news:*

I was able to reproduce it on my Ubuntu 20.04 LTS machine by adjusting your 
code snippet (without our complicated EAR / EE setup). Started the code with 
*-ea* via JVM params. Note: I used Java 17 text blocks for simplicity of XML 
config snippet.

Note: I installed the *SFArabic.ttf* system-wide and re-generated the Ubuntu 
font cache.

Another (simple) way to reproduce is to checkout the current FOP master on 
GitHub and conduct a "mvn clean install" with the font being installed on the 
local system. This will trigger the following unit test:

A possible fix / solution / workaround would (maybe - I was just looking at the 
code) probably be:

1. Pass "useAdvanced" as a new parameter to FontInfoFinder#find(...). To avoid 
breaking the API, we could do something like:

 
{code:java}
 public EmbedFontInfo[] find(URI fontURI, InternalResourceResolver 
resourceResolver, FontCache fontCache) {
  return find(fontURI, resourceResolver, fontCache);
 }
 
 public EmbedFontInfo[] find(URI fontURI, InternalResourceResolver 
resourceResolver, FontCache fontCache, boolean useAdvanced) {
  ...
 }
 {code}
 
 2. Add a boolean property for "useAdvanced" to the FontManager (?) to 
propagate to the FontFinderInfo / FontAdder.
  
Note: If "complexScriptFeaturues" has the same meaning ie is semantically equal 
to "useAdvanced" in FontInfoFinder, we would need to make sure, that this 
property is passed to the FontManager (after being set via XML or 
programmatically). Something like 
https://issues.apache.org/jira/secure/attachment/13042174/propagate_use_advanced.patch

 

Btw. the same holds for "useKerning", which is set to "true" by default in 
find(...). Shouldn't that be a parameter to, which is passed from the font 
manager to the find(...) method?

Wdyt?

Thanks for updating the documentation as well as your time.

I tested the sample code: If I hard-code the path to SFArabic via  the font is loaded and used (at least no exception / assertion error 
is thrown)

INFORMATION: Rendered page #1.{code}
My issue is, that I do +*not*+ want to use *SFArabic* at all (it is just a 
system font, which is available by default on an MacOS 12.3 and cannot be 
deleted), which is detected during auto scanning by fop.
So I am not quite sure, if specifying the specific font will help with the 
original issue which occurs during auto-scanning.

Is there a configuration option to exclude fonts from being scanned?

*The good news:* 

I was able to reproduce it on my Ubuntu 20.04 LTS machine by adjusting your 
code snippet (without our complicated EAR / EE setup). Started the code with 
*-ea* via JVM params.

Note: I installed the *SFArabic.ttf* system-wide and re-generated the Ubuntu 
font cache.

  return find(fontURI, resourceResolver, fontCache);
 }
 
 public EmbedFontInfo[] find(URI fontURI, InternalResourceResolver 
resourceResolver, FontCache fontCache, boolean useAdvanced) {
  ...
 }
 {code}
 
 2. Add a boolean property for "useAdvanced" to the FontManager (?) to 
propagate to the FontFinderInfo / FontAdder.
  
Note: If "complexScriptFeaturues" has the same meaning ie is semantically equal 
to "useAdvanced" in FontInfoFinder, we would need to make sure, that this 
property is passed to the FontManager (after being set via XML or 
programmatically). Something like [^propagate_use_advanced.patch] - if this 
goes in the right direction, I can also prepare a PR on GitHub.

Btw. the same holds for "useKerning", which is set to "true" by default in 
find(...). Shouldn't that be a parameter to, which is passed from the font 
manager to the find(...) method?

Wdyt?

[jira] [Commented] (FOP-3062) AssertionError in GlyphPositioningTable$DeviceTable with SFArabic.ttf

 ] 

Richard Zowalla commented on FOP-3062:
--

A possible fix / solution / workaround would (maybe - I was just looking at the 
code) probably be:

1. Pass "useAdvanced" as a new parameter to FontInfoFinder#find(...). To avoid 
breaking the API, we could do something like:

 
{code:java}
 public EmbedFontInfo[] find(URI fontURI, InternalResourceResolver 
resourceResolver, FontCache fontCache) {
  return find(fontURI, resourceResolver, fontCache);
 }
 
 public EmbedFontInfo[] find(URI fontURI, InternalResourceResolver 
resourceResolver, FontCache fontCache, boolean useAdvanced) {
  ...
 }
 {code}
 
 2. Add a boolean property for "useAdvanced" to the FontManager (?) to 
propagate to the FontFinderInfo / FontAdder.
  
Note: If "complexScriptFeaturues" has the same meaning ie is semantically equal 
to "useAdvanced" in FontInfoFinder, we would need to make sure, that this 
property is passed to the FontManager (after being set via XML or 
programmatically). Something like [^propagate_use_advanced.patch] 

 

Btw. the same holds for "useKerning", which is set to "true" by default in 
find(...). Shouldn't that be a parameter to, which is passed from the font 
manager to the find(...) method?

Wdyt?

This is a developer machine. We are starting TomEE Maven Plugin, which has 
Assertions enabled by default ;) (and it cannot be disabled easily...) but 
would also impact unit tests, which are using assertions.

This is a developer machine. We are starting TomEE Maven Plugin, which has 
Assertions enabled by default ;) (and it cannot be disabled easily...) but 
would also impact unit tests, which are using assertions.

I am even not capable of removing / moving this specific Apple system font 
away, so auto detection will always fail with this assertion error in a dev 
setup.

Thanks for your reply - your help is very much appreciated! :)

I applied the the part of the documentation above by using
fopBuilder.setComplexScriptFeatures(false); 
as FOUserAgent does not have this method as suggerated by the docs *and* via 
the XML config. The value is set for the given factory configuration (as shown 
in the screenshot) above.

If I am looking into the stacktrace and navigate to  [line 
170|https://github.com/apache/xmlgraphics-fop/blame/1c35037f340df7ad112da5af646c878d2cf927c9/fop-core/src/main/java/org/apache/fop/fonts/autodetect/FontInfoFinder.java#L170]
{code:java}
FontInfoFinder#find(URI fontURI, InternalResourceResolver resourceResolver, 
FontCache fontCache)
{code}
*useAdvanced* is set to true (by default) and is then passed to the font loader 
(and so on). I didn't see an override for this flag (based on the given config).

Basically, I am wondering, why the FontInfoFinder doesn't honour this setting 
specified by the factory?

Tried disabling via
{code:java}
fopBuilder.setComplexScriptFeatures(false); {code}
and via 
{code:java}
   {code}
but that led to the same exception. I debugged into the FopFactory and the 
value is set:

fo:basic-link elements generate links with default alt text

[Richard Cohen via fop-dev]

Hi,

When we generate PDFs with PDF/UA-1 enabled (as specified in the fop.xconf 
file),  elements generate  tags in the PDF with alt text 
automatically set to "No alternate text specified." This causes 508 compliance 
issues since screen readers read this alt text instead of the specified link 
text. We're wondering why  elements are treated this way since 
there should be no need for alternate text if the link text is sufficiently 
descriptive. We can work around this by specifying the desired link text in the 
fox:alt-text attribute of the  element, but it was our 
understanding that the fox:alt-text attribute was intended for non-text 
elements such as images.

Thanks,

Rich Cohen
