Embodiment
Below in conjunction with embodiment and accompanying drawing character library merging method provided by the invention and related system are described in detail.In the following embodiments, the character library describing mode adopts TrueType character library commonly used in the Windows system, wherein related data or order format are based on the text that the TTX that develops software derives, and the data structure of this character library mainly comprises file header and some tables of data, for example maxp table, fpgm table, prep table, glyf table etc.
See also Fig. 1, the workflow of character library merging method provided by the invention is as follows:
Particularly, read the numerical value of the parameter m axFunctionDefs in the maxp table of each character library to be combined, and with the numerical value of these numerical value sums as this parameter m axFunctionDefs in the maxp table that merges the back character library.Simultaneously, read the numerical value of all the other each parameters except that parameter m axFunctionDefs in the maxp table of character library to be combined, and for each parameter, numerical value in its maxp table in each character library to be combined is compared, get the numerical value of wherein maximum numerical value as this parameter in the maxp table that merges the back character library.
Yet in actual applications, different character libraries is when design, and the character library radix that is adopted may be together, and as shown in Figure 2, it is the character library to be combined of AA x BB that the left side rectangle is represented radix, and it is the character library to be combined of CC x DD that the right side rectangle is represented radix.In this case, just need be before abovementioned steps 20, the character library radix adjusted make its coupling, that is to say that mode that can the proportion of utilization conversion makes the radix of character library to be combined reach consistent.For example, if be the benchmark that character library was adopted after the merging with character library radix in right side among Fig. 2, then needing left side character library radix transform be right side character library radix, that is, transform to CC x DD by radix AA x BB, like this, the conversion ratio of horizontal direction is CC/AA, and the conversion ratio on the vertical direction is DD/BB.Generally speaking, CC/AA=DD/BB.After having determined above-mentioned conversion ratio, with the transformation relation of x '=x*CC/AA, y '=y*DD/BB each font that need merge in the character library of left side is carried out transformation of scale, x ' wherein, the coordinate behind the y ' representation transformation, the coordinate before the x, y representation transformation.Can realize the adjustment of character library radix like this.
Similarly, when the design font, different character library manufacturers also can adopt different character library baselines usually, in this case, just need adjust baseline before abovementioned steps 20.For example, Fig. 3 shows two kinds of different character library baselines respectively with Fig. 4, and wherein, baseline height shown in Figure 3 is hs; Baseline height shown in Figure 4 is hd.If with baseline shown in Figure 4 is the baseline that merges the back character library, then need baseline shown in Figure 3 is adjusted, that is, in the vertical direction is adjusted it can obtain baseline shown in Figure 4.That is to say that above-mentioned baseline adjustment is exactly that the font coordinate among Fig. 3 has been carried out such adjustment: promptly, make y '=y+hd-hs, wherein, y and y ' represent the coordinate before and after each point transformation in the font respectively.
In the practical application,, then also need in font composing parameter and the cvt table related parameter adjustment being arranged if because of the radix of character library to be combined and/or baseline is inequality that it has been carried out above-mentioned relevant adjustment.
Particularly, adopted in character library to be combined under the situation of different character library radixes and/or character library baseline, for the character library that is applicable to horizontal type-setting mode, with predetermined merging back character library radix is standard, and the parameter relevant with the composing of font level in the hmtx table of character library to be combined adjusted; For the character library that is applicable to vertical type-setting mode, be standard with predetermined merging back character library radix and/or baseline, to adjusting in the vmtx table of character library to be combined with the vertical relevant parameter of setting type of font; And, be standard with predetermined merging back character library radix, to the overall steering order in the cvt table of character library to be combined is employed related parameter adjustment arranged.
In addition, each character library to be combined all has numerous functions usually, and this is avoided in different character libraries to be combined function with same functions numbering being carried out different suchlike problems such as definition with regard to being difficult to.In this case, if the function numbering is not adjusted when merging character library and, then can make to merge to exist in the character library of back to number and the collision problem (be designated hereinafter simply as function and number collision problem) that phenomenon causes such as repeat because of function to its directly mergings/uses.For this reason, just need before abovementioned steps 20, the relevant function numbering in the character library to be combined be adjusted.For example, the relevant function numbering in fpgm table, prep table, the glyf table is adjusted.
Wherein, the adjustment of related function numbering can realize like this in the fpgm table: promptly, read the numerical value of the parameter m axFunctionDefs in the maxp table of each character library to be combined, keep the function numbering in the fpgm table of first character library constant, each function numbering in the fpgm table of other character libraries to be combined is added the numerical value sum of the parameter m axFunctionDefs in this character library sequence number each character library before respectively, thereby eliminate above-mentioned function numbering collision problem.
For the called function numbering in the prep table of each character library to be combined, can adjust according to the function numbering regulation rule that fpgm table in the same character library is adopted, thereby eliminate above-mentioned function numbering collision problem.
For the called function numbering in the glyf table of each character library to be combined, can adjust according to the function numbering regulation rule that fpgm table in the same character library or prep table are adopted, thereby eliminate above-mentioned function numbering collision problem.
Describe character library merging method provided by the invention in detail below in conjunction with a specific embodiment shown in Figure 5.For ease of explanation, in the present embodiment with the example of merging into of two character libraries, promptly, first character library and second character library are merged and generate the 3rd character library, in other words, second character library merged in first character library generate the 3rd character library, wherein first character library and second character library are called character library to be combined, and the 3rd character library is called and merges the back character library.
Wherein, in the step 110, under the character library radix that character library to be combined adopted situation inequality, be that standard is adjusted the radix of character library to be combined with predetermined merging back character library radix.Concrete method of adjustment and process are similar to the front in conjunction with the explanation that Fig. 2 did, and do not repeat them here.
One, the adjustment of function numbering in the fpgm table.
At first, number, earlier the function definition mode in the fpgm table is elaborated for ease of the function how explanation is adjusted in the fpgm table.Usually, the formal definition with function in the fpgm of the TrueType character library table has overall steering order, so that call in other places in character library.The following form of the general employing of this fpgm table:
<fpgm>
<assembly>

In fact, the function definition in the fpgm table generally can adopt following dual mode.Wherein, first kind of mode is: function numbering of defined function numbering, and every definition one by one just defines this function body immediately, for example:
NPUSHB[]a
FDEF[]
...
EDEF[]
The second way is: at first defines some function numberings, and then defines the respective function body one by one, for example:
NPUSHB[]a?b?c...n
FDEF[]
...
EDEF[]
FDEF[]
...
EDEF[]
...
...
FDEF[]
...
EDEF[]
In fact, above-mentioned two kinds of definition modes may be used alone, can also be used in combination.Wherein, NPUSHB[] after alphabetical a b c...n representative function numbering, for being not less than zero integer.
Next, describe the method for adjustment and the process of function numbering in the fpgm table in detail.
In actual applications, no matter adopt above-mentioned which kind of definition mode, there is function numbering collision problem as long as judge character library to be combined, just can adopt following manner to be solved: promptly, in the maxp of first character library and second character library table, read the numerical value of the parameter m axFunctionDefs of expression maximal function numbering respectively, keep the function numbering in the fpgm table of first character library constant, each function numbering in the fpgm table of second character library is added the numerical value of the maxFunctionDefs in first character library respectively; Simultaneously, with the numerical value sum of the parameter m axFunctionDefs in the maxp of two character libraries table numerical value as the parameter m axFunctionDefs in the maxp table that merges the back character library.Can solve the function numbering collision problem in the fpgm table of first character library and second character library like this.
Particularly, from the maxp table of first character library, read the numerical value of the parameter m axFunctionDefs of this character library maximal function numbering of expression earlier, be designated as maxFunctionDefs_1; Correspondingly, from the maxp table of second character library, read the numerical value of the parameter m axFunctionDefs of this character library maximal function numbering of expression, be designated as maxFunctionDefs_2; Then, keep the function numbering in the fpgm table of first character library constant, each function in the fpgm table of second character library is numbered the numerical value that adds the maxFunctionDefs in first character library respectively, that is, each function numbering in the fpgm table of second character library is added maxFunctionDefs_2 respectively.Like this, promptly finished the adjustment of the function numbering in the fpgm table of character library to be combined.
Then, with the function NPUSHB[in the fpgm table] be that example describes the function numbering of how adjusting in the fpgm table in detail.Wherein, this function NPUSHB[] adopt aforementioned first kind of function definition mode, function is numbered a.
As previously mentioned, keep function numbering in the fpgm table of first character library constant and only change respective function numbering in the fpgm table of second character library, that is to say, respective function numbering in the fpgm table of second character library is added maxFunctionDefs_1, like this, above-mentioned function numbering a is adjusted to a+maxFunctionDefs_1, correspondingly, the function NPUSHB[in the fpgm of second character library table] definition promptly be adjusted to:
NPUSHB[](a+maxFunctionDefs_1)
FDEF[]
...
EDEF[]
Similarly, the function numbering that other function definitions in the fpgm table are related is also done above-mentioned adjustment, the function numbering that can finish in the fpgm table of character library to be combined is adjusted.
It is to be noted, to the function numbering in the fpgm of second character library table adjust finish after, content whole in this fpgm table can be appended to the back or the foremost of the fpgm table of first character library, simultaneously the maxFunctionDefs in the maxp table of first character library be revised as (maxFunctionDefs_1+maxFunctionDefs_2).That is to say, can after the function numbering adjustment in the fpgm table is finished, carry out the merging of fpgm table at once.Certainly, in actual applications, also can carry out the adjustment of fpgm table earlier, and fpgm shown that merging process is postponed and in subsequent step the merging with other tables carry out.
Its two, the adjustment of function numbering in the prep table.
Usually, the following form of the general employing of the table of the prep in the TrueType character library:
<prep>
<assembly>
NPUSHB[]/*244values?pushed*/
119?66?8?31?118?66?8?31?117?67?8?31?116?67?8?31?115?67?8?31?114?67?8?31?113

There is conflict if judge the function numbering of character library to be combined, and the function numbering in the fpgm table adjusted, so just need correspondingly adjust the invoke code (that is, called function is numbered) in the prep table of corresponding character library (that is second character library).Usually, the following form of general employing is come call function in the prep table:
NPUSHB[]a?b?c?d...n
...
CALL[]
Or
NPUSHB[]a?b?c?d...n
...
LOOPCALL[]
CALL wherein or LOOPCALL instruction are the function call instruction.Usually, called function is numbered program and carries out this moment, the operand at storehouse top.For this reason, just need to identify the respective function numbering the numerous data in storehouse earlier, and then it is adjusted with reference to the adjustment mode of function numbering in the aforementioned fpgm table.In actual identification and the adjustment process, can introduce following table 1 usually and realize.And, in identification and adjustment process, also needing to be provided with one in order to write down the operand current location variable pos of current operand position, its initial value is 0.
Table 1:
The location of instruction | Instruction code |
1 | NPUSHB[] |
2 | 119 |
... | ... |
100 | SPVTL[0] |
101 | PUSHB[] |
102 | 10 |
... | ... |
180 | CALL[] |
In the table 1, the location of instruction is the sequence number that each instruction or operand occur in the prep table, since 1 sequential counting.So-called operand refers to the non-operation part in the prep table, is generally and is not less than 0 integer.
Next, with reference to table 1 and the implementation of dummy instruction.At first, when the location of instruction was 1, the corresponding instruction code was NPUSHB[], this instruction code is for instruction but not operand, so the value of operand current location variable pos remains unchanged, and still is 0.
Run to the location of instruction 2 then, the corresponding instruction code is " 119 ", and this instruction code is an operand, so the value of operand current location variable pos need increase by 1, promptly becomes 1.
Next carry out successively, when running to the location of instruction and be 100, its pairing instruction code is " SPVTL[0] ", this instruction code is such instruction: require to extract two operands and do not have rreturn value to be pressed in the storehouse from storehouse, at this moment, suppose operand current location variable pos=50, like this, after executing this instruction, because of taking 2 operands away from the storehouse top, so the value of operand current location variable pos also correspondingly deducts 2 and become 48.
When running to the location of instruction 180, its pairing instruction code is " CALL[] ", and this instruction code is the instruction of call function.Suppose the operand current location variable pos=20 of this moment, then should find the position in storehouse is 20 operand, with this operand (promptly according to same character library, second character library) the function numbering regulation rule in the fpgm table is made amendment, for example, this operand is added maxFunctionDefs_1.
Continue the remaining command in the dry run prep table, as long as meet instruction CALL[] or LOOPCALL[], just revise corresponding operand according to above-mentioned adjustment mode.Like this, can realize adjustment to the related function numbering in the prep of second character library table.
It is to be noted, to the function numbering in the prep of second character library table adjust finish after, content whole in this prep table can be appended to the back or the foremost of the prep table of first character library, this be in fact the numbering of the function in the prep table is adjusted after, carry out the merging of prep table at once.Certainly, in actual applications, the merging of prep table also can be carried out with the merging of other tables after a while.
Its three, the adjustment of function numbering in the glyf table.
There is conflict if judge the function numbering of character library to be combined, and the fpgm table of second character library and/or the related function numbering in the prep table are adjusted, so just need correspondingly adjust corresponding character library (promptly, second character library) the related function numbering in the glyf table, and the font data in this table is partly remained unchanged.Function numbering method of adjustment in the glyf table of second character library and process are similar to method and the process in above-mentioned fpgm table and/or the prep table, do not repeat them here.
Step 140 based on each parameter value in the maxp table of character library to be combined, is provided with each parameter value in the maxp table that merges the back character library.Usually, record the combined data of font required memory distribution condition in the maxp table, its concrete structure is generally as follows:
<maxp>
<!--Most?of?this?table?will?be?recalculated?by?the?compiler-->
<tableVersion?value=″0x10000″/>
