Detailed description of the invention
Below in conjunction with drawings and Examples, technical scheme is described in detail.
First, it will be understood by those skilled in the art that font format here refers to the graphic designs being applied to all numerals, symbol, Chinese character and alphabetic character, it is possible to be called 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 feature, such as regular script, the Song typeface, Arial etc..
In an embodiment of the present invention, UOML standard interface support is class Truetype font format, this font format is taked to be saved in, by embedding word information, the mode being embedded into document in the embedding word stream of correspondence more respectively by fontname, in this application, this type of font format is designated the first font format by us.And what actually also have that many font formats take is the mode being embedded into document in same embedding word stream again that the information of all embedding words is saved in, the SEP form of such as inteilectual company, in this application, this type of font format is designated the second font format by us.Utilize font conversion method and device that the embodiment of the present invention provides, when utilizing UOML standard interface to access the document comprising the second font format, described second font format is converted to the first font format, in the content edited is preserved, described first font format is converted to the second font format.
Fig. 1 show a kind of font conversion method that the embodiment of the present invention provides.As it is shown in figure 1, this font conversion method comprises the steps:
Step 101: when opening the document comprising the second font format, first determines whether whether include embedding word information in document, if it has, perform step 102；If it is not, flow process terminates.
In one particular embodiment of the present invention, embed word stream and refer to the set embedding word information of font format.In certain document, such as embedded in the font coding 2 kinds different of the second font format, respectively 20 characters of regular script coding, the Song typeface 30 characters of coding, these process embedding character are by the document, embed character by 50 of these 2 kinds of kinds of characters codings to store together, formed and embed word stream.
Step 102: obtain the embedding word stream information of the document comprising the second font format.
Step 103: read the attribute information embedding word word stream one by one from embedding of the second font format, the attribute information according to each embedding word, generate a corresponding font coding file respectively by different font codings.
It will be understood by those skilled in the art that the attribute information embedding word may include that in the side-play amount of the font number of character, font coding, character contour information side-play amount in word stream and/or character outline self one or more.
As above in example, to the process embedding word stream it is: one by one from embedding reading 50 embedding characters word stream, and analyze the font coding information of each embedding character, 2 font coding files are generated by font coding difference, respectively the font coding file of regular script coding and the font of Song typeface coding encode file, wherein the font coding document memory of regular script coding puts the character of 20 regular script codings, and the font coding document memory of Song typeface coding puts the character of 30 Song typeface codings.
Step 104: create font Code Mapping Tables (Fontlist) and font coding mapping (FontMap), font coding file content corresponding for font coding is arranged in the embedding word stream of corresponding font coding mapping, by corresponding font coding information registering to font Code Mapping Tables.
In an embodiment of the present invention, need to read out the File header information of embedding word stream from the embedding word stream of the second font format, the attribute information of all embedding words is read out by File header information, by the attribute information of each embedding word, in embedding word stream, unique inquiry the profile information of corresponding character can be read.Due in some cases, the coordinate system that first font format and the second font format adopt in profile information is different and initial point position is different, even hint information also can be variant (as some font format would be likely to occur hint information, some font format is likely not to have hint information), therefore when carrying out font conversion, also need to that the profile information of the second font format is carried out conversion and generate the character contour information meeting the first font format, and be saved in the font coding file of correspondence.
By above several steps, complete the conversion to the first font of second font, the interface that in UOMLSDK, embedding word is correlated with now can be used to carry out the second font document embedding the document functions such as word setting, amendment or deletion so that the document comprising the second font format can be operated by direct use UOML standard interface.Wherein, include the operation of document document is conducted interviews, arrange, revise, deletion etc..
Complete document is arranged operation, after amendment or deleting, when document is preserved, it is necessary to the embedding word information that the word information that embeds of the first font format in now document converts the second font format to preserved.This process is as in figure 2 it is shown, comprise the steps:
Step 201: create the embedded font message file of the second font format, for the embedded font information depositing the second font.
Step 202: take out the font Code Mapping Tables (FontList) in document.
Step 203: travel through this font Code Mapping Tables, encodes according to font, accesses each the font coding mapping (FontMap) in font Code Mapping Tables.If current font coding mapping does not comprise embedding word stream, then continue the next font coding mapping of traversal.If font coding mapping includes embedding word stream, then from this font coding mapping, take out it embed word stream, the content embedding word stream is sequentially stored into the embedded font message file of the second font format.
Step 204: delete the embedding word stream in font coding mapping；As also having the font coding mapping not traveled through, forward step 203 to and continue with next font coding mapping, until all of font coding mapping traversal is complete.
Step 205: close the embedded font message file of the second font format created in step 201, read by file content in core buffer, the second font format obtaining current document embeds word stream, is arranged by file content and completes in this stream to preserve.
In an embodiment of the present invention, need also exist for generating, by the profile information of the first font format carries out conversion, the character contour information meeting the second font format, and be saved in the embedded font message file of the second font format.
Fig. 3 show the flow chart of a kind of font conversion method that one embodiment of the invention provides.In this embodiment, described second font is inteilectual's font format.The present embodiment mainly describes and utilizes UOML standard interface to access the inteilectual's document (SEP document) originally cannot supported.
Step 301: open the SEP document embedding word information containing inteilectual's font format, in the process opening SEP document, takes out the embedding word stream in SEP document from the root node of SEP document.
Step 302: whether judge to embed in word stream has embedding word information；If there being the embedding word information embedded in word stream that obtains, and then perform step 303；Otherwise perform step 314；
Step 303: read the attribute information embedding word word stream one by one from embedding of inteilectual's font format, the attribute information according to each embedding word, generate a corresponding TTF font file respectively by different font codings.
Wherein, from embedding the File header information reading out embedding word stream word stream, read out the attribute information of all embedding words by File header information, by the attribute information of each embedding word, in embedding word stream, unique inquiry reads the profile information (Glyph) of corresponding character.Owing to inteilectual's font format is different from the coordinate system adopted in the profile information of TrueType (Glyph) form and initial point position different, and in the profile information of inteilectual's font format, lacked some information (such as hint) in TrueType form profile information, need that inteilectual's character contour information is carried out conversion and generate the character contour information comprising hint information meeting TrueType form, and be saved in the TTF file of correspondence.
Step 304: find out the font coding mapping (SEP_FontMap) of correspondence in the font Code Mapping Tables (SEP_Fontlist) of SEP document by the fontname of every kind of font, take the embedding word stream of font coding mapping, by the TTF font file curriculum offering of this kind of font coding correspondence to embedding in word stream, and by corresponding font coding information registering font Code Mapping Tables in SEP document.
Step 305: utilize and embed the relevant interface of word in UOMLSDK and SEP document is configured, revises or the document function such as deletion.
Step 306: judge whether to preserve operation SEP document carried out by UOML interface.If preserved, performing step 307, otherwise performing step 314.
Step 307: create inteilectual's embedded font message file, be used for depositing inteilectual's embedded font information.
Step 308: take out word coding body mapping table (SEP_FontList) in SEP document.
Step 309: travel through this font Code Mapping Tables, accesses each font in font Code Mapping Tables and maps (SEP_FontMap).
Step 310: judge whether to comprise embedded font；If it is not, then execution step；If it is, perform step 311.
Step 311: take out its subobject then mapping from this font and embed word stream, the content embedding word stream is sequentially stored into inteilectual's embedded font message file；Delete the embedding word stream in font map element simultaneously.
Now, need to use the dynamic base interface of TrueType character library to travel through the TrueType character outline information that each font coding is corresponding, owing to there is no hint information in the character outline information of inteilectual's font format, and different from the coordinate system that TrueType layout character profile information adopts and initial point, this is accomplished by: to character outline, the TrueType character outline information got is carried out coordinate transform according to inteilectual's font format；And the more point of interpolation can keep the attractive in appearance of font with control character profile when rendering；The character outline information of the inteilectual's font format generated after conversion is stored in inteilectual's word embed in message file；And increase, in inteilectual's word embedding message file, the embedding word attribute information that this character is corresponding.
Step 312: judge whether that having traveled through all of font maps, if it is, perform step 313；Otherwise return and perform step 309.
Step 313: close inteilectual's embedded font message file, read in core buffer by the file content obtained, the inteilectual's font obtaining current document embeds word stream, is arranged by file content and completes in this stream to preserve.
Step 314: close SEP document.
Utilize the technical scheme shown in Fig. 3, the problem that the embedding word information solving to preserve in SEP document can not directly use UOML interface to conduct interviews so that history SEP document can use the UOML interface of standard to conduct interviews, revise.
