The parameters of a file in this format are tuned through the [AltoExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/altoexportparams) object. | | FEF\\\_DOCX | DOCX (Microsoft Word 2007 and later) format. The parameters of the file in this format are tuned through the [RTFExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/rtfexportparams) object. | | FEF\\\_EPUB | EPUB format. The parameters of a file in this format are tuned through the [EBookExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/ebookexportparams) object. | | FEF\\\_FB2 | FB2 format. The parameters of a file in this format are tuned through the [EBookExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/ebookexportparams) object. | | FEF\\\_HTMLVersion10Defaults | HTML format. The parameters of a file in this format are tuned through the [HTMLExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/htmlexportparams) object. The default encoding is selected in the same way as in the 10th version. This constant will be removed in the next version. | | FEF\\\_HTMLUnicodeDefaults | HTML Unicode format. The parameters of a file in this format are tuned through the [HTMLExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/htmlexportparams) object. The default encoding is UTF-8. | | FEF\\\_JSON | JSON format. The parameters of a file in this format are tuned through the [JsonExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/jsonexportparams) object. | | FEF\\\_ODT | ODT (Open Office document) format. The parameters of a file in this format are tuned through the [RTFExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/rtfexportparams) object. | | FEF\\\_PDF | PDF or PDF/A format. The parameters of a file in this format are tuned through the [PDFExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/pdfexportparams) object. Whether to export to PDF or PDF/A is defined by the PDFAComplianceMode property of this object. | | FEF\\\_PPTX | PPTX (Microsoft PowerPoint 2007 and later) format. The parameters of a file in this format are tuned through the [PPTExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/pptexportparams) object. | | FEF\\\_RTF | Microsoft RTF format. The parameters of the file in this format are tuned through the [RTFExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/rtfexportparams) object. | | FEF\\\_TextVersion10Defaults | TXT or CSV format. The parameters of a file in this format are tuned through the [TextExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/textexportparams) object. Whether to export to TXT or CSV is defined by the ExportFormat property of this object. The default encoding is selected in the same way as in the 10th version. This constant will be removed in the next version. | | FEF\\\_TextUnicodeDefaults | TXT Unicode or CSV Unicode format. The parameters of a file in this format are tuned through the [TextExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/textexportparams) object. Whether to export to TXT or CSV is defined by the ExportFormat property of this object. The default encoding is UTF-8. | | FEF\\\_XLS | XLS (Microsoft Excel) format. The parameters of a file in this format are tuned through the [XLExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/xlexportparams) object. | | FEF\\\_XLSX | XLSX (Microsoft Excel 2007 and later) format. The parameters of a file in this format are tuned through the [XLExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/xlexportparams) object. | | FEF\\\_XML | XML format. The parameters of a file in this format are tuned through the [XMLExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/xmlexportparams) object. | | FEF\\\_XPS | XPS format. The parameters of a file in this format are tuned through the [XPSExportParams](/fine-reader/engine/api-reference/parameter-objects/export-parameters/xpsexportparams) object. | ## Used in [IFRDocument::Export](/fine-reader/engine/api-reference/document-related-objects/frdocument/export-method) [IFRDocument::ExportPages](/fine-reader/engine/api-reference/document-related-objects/frdocument/exportpages-method) [IFRDocument::ExportToMemory](/fine-reader/engine/api-reference/document-related-objects/frdocument/exporttomemory-method) [IFRPage::Export](/fine-reader/engine/api-reference/document-related-objects/frpage/export-method) [IEngine::RecognizeImageFile](/fine-reader/engine/api-reference/engine-object-iengine-interface/processing-methods/recognizeimagefile-method) [IDocumentViewerEvents::OnExportPages](/fine-reader/engine/visual-components-reference/idocumentviewerevents/onexportpages-method)
