This class holds flags to control PDF/A conversion for cases when source PDF document doesn't correspond to PDF specification. If flags of this clas are used it decreases performance but it's necessary when source PDF document can't be convert into PDF/A format by usual way. By default all flags are set to false.

This class describes rules which can be used to tune process of copy encoding data for cases when TrueType symbolic font has more than one encoding. Some PDF documents after conversion into PDF/A format could have error "More than one encoding in symbolic TrueType font's cmap". What is a reason of this error? All TrueType symbolic fonts have special table "cmap" in it's internal data. This table maps character codes to glyph indices. And this table could contain different encoding subtables which describe encodings used. See advanced info about cmap tables at https://developer.apple.com/fonts/TrueType-Reference-Manual/RM06/Chap6cmap.html. Usually cmap table contains several encoding subtables, but PDF/A standard requires that only one encoding subtable (3,0) must be leaved for this font in PDF/A document. And key question here - what data must be taken from another subtables to copy into destination encoding table (3,0)? Majority of fonts have 'well-formed' cmap tables where every encoding subtable is fully consistent with another subtable. But some fonts have cmap tables with collisions - where for example one subtable has glyph index 100 for unicode 100, but another subtable has glyph index 200 for the same unicode 100. To solve this problems special strategy needed. By default following strategy used: mac subtable(1,0) is looked for. If this table is found, only this data used to fill destination table (3,0). If mac subtable is not found then all subtables except (3,0) are iterated and used to copy data into destination (3,0) subtable. Also mapping for every unicode(unicode, glyph index) is copied into destination table only if destination table has no this unicode at current moment. So, for example if first subtabe has glyph index 100 for unicode 100, and next subtable has glyph index 200 for the same unicode 100, only data from first subtable (unicode=100, glyph index = 100) will be copied. So each previous subtable takes precedence over the next. Properties of this class PdfASymbolicFontEncodingStrategy help tune default behaviour. If property PreferredCmapEncodingTable of type PdfASymbolicFontEncodingStrategyQueueItemCMapEncodingTableType is set, then relevant subtable will be used in precedence to mac subtable(1,0). Value 'MacTable' from enumeration PdfASymbolicFontEncodingStrategyQueueItemCMapEncodingTableType has no sense in this case, cause it points on the same mac subtable (1,0) which will be used by default. Property CmapEncodingTablesPriorityQueue discards all priorities for any subtable. If this property is set, then only subtables from declared queue will be used in specified order. If subtables specified are not found then default iteration of all subtables and copy strategy described above will be used. Object PdfASymbolicFontEncodingStrategyQueueItem specifies encoding subtable used. This subtable can be set via combination of members(PlatformID, PlatformSpecificID) or via PdfASymbolicFontEncodingStrategyQueueItemCMapEncodingTableType enumeration.

Specifies encoding subtable. Each encoding subtable has unique combination of parameters (PlatformID, PlatformSpecificID). Enumeration PdfASymbolicFontEncodingStrategyQueueItemCMapEncodingTableType and property CMapEncodingTable were implemented to make easier set of encoding subtable needed.

You can assign to this property custom strategy that implements processing or/and saving of one CSS's part that was created during conversion of PDF to HTML . In such case processing (like saving to stream or disk) must be done in that custom code

You can assign to this property delegate created from custom method that implements creation of URL of CSS referenced in generated HTML document. F.e. if You want to make CSS referenced in HTML f.e. as "otherPage.ASPX?CssID=zjjkklj" Then such custom strategy must return "otherPage.ASPX?CssID=zjjkklj"

Result of conversion can contain one or several HTML-pages ( that also can reference external files like images or fonts) You can assign to this property delegate created from custom method that implements processing of got HTML-page(HTML itself) that was created during conversion. In such case processing (like saving in stream or disk) can be done in that custom code . In such case All the necessary actions for saving of HTML page's markup must be undertaken in code of supplied method, because saving of result in code of converter will be not in use. If processing for this or that case for some reason must be done by converter's code itself, not in custom code, please set in custom code flag 'CustomProcessingCancelled' of 'htmlSavingInfo' parameter's variable : it signals to converter that all the necessary steps for processing of that resource must be done in converter itself in same way as if there was no any external custom saving code .

To this property You can assign delegate created from custom method that implements processing of external resource(Font or Image) that was extracted from PDF and must be saved as external resource during conversion of PDF to HTML. In such case processing (like saving in stream or disk) can be done in that custom code and that custom code must return path(or any another string without quotemarks) that will be afterwards incorporated into generated HTML instead of original supposed path to that image resource. In such case All the necessary actions for saving of image must be undertaken in code of supplied method, because saving of result in code of converter will be not in use . If processing for this or that file for some reason must be done by converter's code itself, not in custom code, please set in custom code flag 'CustomProcessingCancelled' of 'resourceSavingInfo' parameter's variable It signals to converter that all the necessary steps for processing of that resource must be done in converter itself as if there was no any external custom code .

Sometimes it's necessary to avoid usage of internal loader of external resources(like images or CSSes) and supply custom method, that will get requested resources from somewhere. For example during usage of Aspose.Pdf in cloud direct access to referenced files impossible, and some custome code put into special method should be used. This delegate defines signature of such custom method.

Procedure for customize header and footer.

To property of such type You can assign delegate created from custom method that implements processing of external saving of image that was extracted from SVG created from PDF and must be saved as external resource during conversion of PDF to HTML. In such case processing (like self-made saving into stream or on disk) can be done in that custom code and that custom code must return path(or any another string without quotemarks) that will be afterwards incorporated into generated SVG instead of original supposed path to that image resource. In such case all the necessary actions for saving of image must be undertaken in code of supplied method, because saving of result in code of converter will be not in use. If processing for this or that file for some reason must be done by converter's code itself, not in custom code, please set in custom code flag 'CustomProcessingCancelled' of 'imageSavingInfo' parameter's variable It signals to converter that all the necessary steps for processing of that resource must be done in converter itself as if there was no any external custom code . represents information about saved image that can be use in custom code
