Embodiment
Below in conjunction with drawings and Examples technical scheme of the present invention is described in detail.
At first, it will be understood by those skilled in the art that the font format here refers to the graphic designs that is applied to all numerals, symbol, Chinese character and alphabetic character, also can be described as form or printed words, such as TrueType font, PostScript font, inteilectual's font etc.; Wherein every kind of font comprises again the font coding of multiple different-style characteristics, such as regular script, the Song typeface, Arial etc.
In an embodiment of the present invention, the support of UOML standard interface be class Truetype font format, this font format is taked will to embed respectively word information by fontname and is kept at the mode that is embedded into again document in the corresponding embedding word stream, in this application, we are designated the first font format with this type of font format.And what also have in fact that many font formats take is that all information that embed words are kept at the mode that is embedded into again document in the same embedding word stream, SEP form such as inteilectual company, in this application, we are designated the second font format with this type of font format.The font conversion method and the device that utilize the embodiment of the invention to provide, when utilizing the access of UOML standard interface to comprise the document of the second font format, described the second font format is converted to the first font format, in editor's content is preserved, described the first font format is converted to the second font format.
Figure 1 shows that a kind of font conversion method that the embodiment of the invention provides.As shown in Figure 1, this font conversion method comprises the steps:
Step 101: when opening the document that comprises the second font format, at first judge whether to include in the document to embed word information, if having, execution in step 102; If no, then flow process finishes.
In a specific embodiment of the present invention, embed the set that word stream refers to the embedding word information of font format.2 kinds of different font codings of the second font format for example in certain document, have been embedded, be respectively 20 characters of regular script coding, 30 characters of Song typeface coding, in the document to these processing that embed character be, 50 embedding characters of these 2 kinds of kinds of characters codings are stored together, form and embed word stream.
Step 102: the embedding word stream information that obtains the document that comprises the second font format.
Step 103: from the embedding word stream of the second font format, read one by one the attribute information that embeds word, embed the attribute information of word according to each, generate respectively the font coded file of a correspondence by different font codings.
It will be understood by those skilled in the art that the attribute information that embeds word can comprise: the font of character number, font coding, character contour information in word stream side-play amount and/or the side-play amount of character outline self in one or more.
As above in the example, to the processing that embeds word stream be: from embed word stream, read 50 one by one and embed character, and analyze the font coded message that each embeds character, by 2 font coded files of the different generations of font coding, be respectively the font coded file of regular script coding and the font coded file of Song typeface coding, wherein deposit the character of 20 regular script codings in the font coded file of regular script coding, deposit the character of 30 Song typeface codings in the font coded file of Song typeface coding.
Step 104: create font coding mapping table (Font list) and font coding mapping (FontMap), the font coded file content that font coding is corresponding is set in the embedding word stream of corresponding font coding mapping, and the font coded message of correspondence is registered in the font coding mapping table.
In an embodiment of the present invention, need to from the embedding word stream of the second font format, read out the file header information that embeds word stream, read out the attribute information that all embed word by file header information, embed the attribute information of word by each, can be in embedding word stream unique inquiry read the profile information of corresponding character.Because in some cases, the coordinate system that the first font format and the second font format adopt in profile information is different and initial point position is different, even also can variantly (may there be hint information in hint information such as some font format, some font format may not have hint information), therefore when carrying out the font conversion, also need the profile information of the second font format is changed the character contour information that meets the first font format that generates, and it is saved in the corresponding font coded file.
By above several steps, finished the conversion of the second font to the first font, can use this moment the interface that the embedding word is correlated with among the UOML SDK that the second font document is embedded the document functions such as word setting, modification or deletion, so that directly use the UOML standard interface can the document that comprise the second font format be operated.Wherein, to the operation of document comprise to document conduct interviews, arrange, revise, deletion etc.
Finish after the documents such as setting, modification or deletion to document, when document was preserved, the embedding word information that the embedding word information of the first font format in this moment document need to be converted to the second font format was preserved.This process comprises the steps: as shown in Figure 2
Step 201: create the embedded font message file of the second font format, to be used for depositing the embedded font information of the second font.
Step 202: take out the font coding mapping table (Font List) in the document.
Step 203: travel through this font coding mapping table, according to the font coding, each the font coding mapping (Font Map) in the access font coding mapping table.Do not embed word stream if do not comprise in the mapping of current font coding, then continue the mapping of the next font coding of traversal.Embed word stream if include in the mapping of font coding, then from this font coding mapping, take out it and embed word stream, the content that embeds word stream is deposited successively in the embedded font message file of the second font format.
Step 204: the embedding word stream in the mapping of delete font coding; As also having the not font coding mapping of traversal, forward step 203 to and continue to process the mapping of next font coding, until all fonts coding mapping traversal is complete.
Step 205: close the embedded font message file of the second font format that creates in the step 201, file content is read in the core buffer, the second font format of obtaining current document embeds word stream, file content is set in this stream finishes preservation.
In an embodiment of the present invention, need equally to change the profile information of the first font format generating the character contour information that meets the second font format, and it is saved in the embedded font message file of the second font format.
Figure 3 shows that the process flow diagram of a kind of font conversion method that one embodiment of the invention provides.In this embodiment, described the second font is inteilectual's font format.The present embodiment is mainly described the inteilectual's document (SEP document) that utilizes the access of UOML standard interface originally can't support.

Step 303: from the embedding word stream of inteilectual's font format, read one by one the attribute information that embeds word, embed the attribute information of word according to each, generate respectively the TTF font file of a correspondence by different font codings.
Wherein, from embed word stream, read out the file header information that embeds word stream, read out the attribute information that all embed word by file header information, embed the attribute information of word by each, unique inquiry reads the profile information (Glyph) of corresponding character in embedding word stream.Because the coordinate system that adopts in the profile information of inteilectual's font format and TrueType (Glyph) form is different and the initial point position difference, and some information (such as hint) in the TrueType form profile information in the profile information of inteilectual's font format, have been lacked, inteilectual's character contour information need to be changed generation and meet the character contour information that comprises hint information of TrueType form, and be saved in the corresponding TTF file.
Step 304: the fontname by every kind of font in the font coding mapping table (SEP_Fontlist) of SEP document finds out corresponding font coding mapping (SEP_FontMap), get the embedding word stream of font coding mapping, along for accommodation into embedding in the word stream, and the font coded message of correspondence is registered in the font coding mapping table in the SEP document in the TTF font file that this kind font coding is corresponding.
Step 305: utilize among the UOML SDK to embed the relevant interface of word and the SEP document is arranged, revises or the document function such as deletion.
Step 306: judge whether to preserve the operation of the SEP document being carried out by the UOML interface.If preserve then execution in step 307, otherwise execution in step 314.
Step 307: create inteilectual's embedded font message file, be used for depositing inteilectual's embedded font information.
Step 308: take out the word coding body mapping table (SEP_FontList) in the SEP document.
Step 309: travel through this font coding mapping table, each the font mapping (SEP_FontMap) in the access font coding mapping table.
Step 310: judge whether to comprise embedded font; If not, execution in step then; If so, execution in step 311 then.
Step 311: then from this font mapping, take out its subobject and embed word stream, deposit successively the content that embeds word stream in inteilectual's embedded font message file; Embedding word in the delete font map element flows simultaneously.
At this moment, need to use the dynamic base interface of TrueType character library to travel through TrueType character outline information corresponding to each font coding, owing in the character outline information of inteilectual's font format, not having hint information, and different from coordinate system and initial point that TrueType layout character profile information adopts, this just needs: the TrueType character outline information of getting is carried out coordinate transform according to inteilectual's font format to character outline; And the more point of interpolation can keep the attractive in appearance of font with the control character profile when playing up; The character outline information of inteilectual's font format of generation after the conversion is deposited in inteilectual's word embedding message file; And in inteilectual's word embedding message file, increase embedding word attribute information corresponding to this character.
Step 312: judge whether to have traveled through all font mappings, if so, then execution in step 313; Otherwise return execution in step 309.
Step 313: close inteilectual's embedded font message file, the file content that obtains is read in the core buffer, the inteilectual's font that obtains current document embeds word stream, file content is set in this stream finishes preservation.
Step 314: close the SEP document.
Utilize technical scheme shown in Figure 3, solve the problem that the embedding word information of preserving in the SEP document can not directly use the UOML interface to conduct interviews, so that the UOML interface that historical SEP document can Application standard conducts interviews, revises.
