Known Issues and Workarounds

Mac OS version limitations

The following functionality of FineReader Engine 11 for Windows is not available in the Mac OS version:

• DjVu opening
• Scanning
• ICR/OMR
• Visual Components and other GUI elements
• WDP/WIC/BITMAP input formats and other Windows-specific functionality
• PDF text layer reusing
• Attachments extraction from PDF
• Bookmarks extraction from PDF
• Metadata extraction from PDF (the information about author, keywords, subject and title)

Java wrapper is not included into the distribution

Though we have partly functional Java wrapper for the Engine it still misses some important parts.

In some cases current version of the wrapper is enough, so please consult with HQ product analyst in case of urgent need.

Some API is not implemented

The following API is not implemented in FRE 10 and FRE 11:

• IFootnoteSeries::HasSeparator. Always returns “true”.
• ITextPicture::ColumnNumber. Always returns “0”.
• ICharParams::IsWordStart. Always returns “false”. It is true only for character parameters got through IWordRecognitionVariants interface.
• IIncut::TextWrapping. Always returns “TW_Undefined”.
• IRunningTitlesSeriesText::HasSeparator. Always returns “false”.

The implementation is not planned.

Farsi language is based on Arabic language

Farsi OCR output indicates Language ID as Arabic (CharParams::LanguageId = LI_ArabicSaudiArabia). This is because Farsi technology preview is based on Arabic OCR language.

The fix will be available in FRE 12.

IPDFMRCParams::MonochromeText doesn’t work correctly

Different algorithms of compressions during export to PDF are used with IPDFMRCParams::MonochromeText set to FALSE or DEFAULT whereas default value is FALSE.

Language auto detection uses CJK resources though none is selected for OCR

‘Cjk.*’ resource files are used while RecognizerParams::LanguageDetectionMode = TSPV_Yes even though recognition languages set does not include any of CJK languages.

The fix will be available in the FRE 11 R7. The proxy feature description is missing in the documentation

30% slowdown in all scenarios

Internal tests shows that this release got 30% slowdown comparing to R2.

We are investigating the reason and working on a patch.

AddImageFileFromMemory does not open PDF files

An attempt to open a PDF file from a memory ends up with the error ‘The image file you specify is empty.’

R7 will include a fix.
