The problem of capacitive.
Before the specific steps of detailed description the present embodiment, SVG file and font work that first the technical program is related to
Brief description.
The SVG file is scalable vector graphics.It is a kind of language with XML definition, for describing two-dimentional arrow
Amount and vector/grid graph.SVG directly can describe image with code, can be schemed with any word processing tool open SVG
Picture is made image have interactive function by changing section code, and can be inserted at any time in HTML through browser and see
It sees.SVG provides the Drawing Object of 3 seed types: vector graphics is (vectorgraphicshape for example: by straight line and curve group
At path), image (image), text (text).Drawing Object such as can also be grouped, add pattern, transformation, combination at the behaviour
Make, feature set includes nested transformation (nestedtransformations), shear path (clippingpaths), alpha illiteracy
Plate (alphamasks), filtering effects (filtereffects), template object (templateobjects) and other extensions
(extensibility)。
In SVG file, have<text>,<path>and<tspan>label.Wherein,<path>label is can in SVG
The label in path is defined with series of orders.It uses<path>when label, just as controlling a paintbrush with the mode of instruction,
Such as: mobile paintbrush draws a line, lifts paintbrush after drawing a curve to a certain coordinate position.Using following when defining path
Instruction:
M=moveto (M X, Y): paintbrush is moved to specified coordinate position；
L=lineto (L X, Y): straight line is drawn to specified coordinate position；
C=curveto (C X1, Y1, X2, Y2, ENDX, ENDY): shellfish matches curve three times；
Q=quadratic Belzier curve (Q X, Y, ENDX, ENDY): secondary shellfish matches curve；
Z=closepath (): Turn Off Path.
<text>label is used to define the label that text is shown in SVG, and<tspan>label is used in<text>, is used
The fine tuning on position or pattern is carried out with the text for being included to it.
The font, be describe in computer systems it is a certain set text external form feature data, usually with
In system files, common format has openType, trueType, svg etc. for specific format storage.Font- can be passed through
Family attribute provides the font family of element, the value of font-family attribute be for some element type family title or/
And the precedence table that class Praenomen claims.Browser will use its identifiable first value.
When setting font title, Chinese can be directly write.But it is mismatched at document No. (GB2312, UTF-8 etc.)
When can generate the mistake of messy code.To this end it is possible to use, Unicode coding avoids these mistakes to write font name.Such as:
Font-family: " 5FAE 8F6F 96C5 9ED1 ", expression set font as " Microsoft is refined black ".
Unicode:(Chinese: Unicode, international code, Unicode, single code) it is a Xiang Ye in computer science
Boundary mark is quasi-.It arrange to most writing system in the world, coding, allows computer with more simple mode
To be presented and handle text.
Embodiments herein provides a kind of method of text conversion, and the method for the text conversion is by will be in SVG
Character string be fabricated to image, will need to use character string hereof and be substituted using the image, and realize and allow SVG any
Can show in the system of SVG, text can be shown according to what appearance described in it was not changed completely.The text
The embodiment of the method for word conversion is as follows:
Fig. 1 and Fig. 2 is please referred to, which respectively show the methods of the text conversion provided according to an embodiment of the present application
Flow chart；And show the schematic diagram of the text conversion provided according to an embodiment of the present application；
The method of the text conversion, comprising:
Step S101, parsing vector graphics file obtain text information.
In the present embodiment, the parsing vector graphics file obtains text information, can realize in the following way: logical
Resolver is crossed, the vector graphics file is parsed, corresponding text information is obtained from the vector graphics file.
It should be noted that the text information, refers to character or document without format information.Such as: in notepad
Character be plain text because it is without the information such as font, font size, paragraph format.The text information in the present embodiment
It is interior, it may include the character string of a character or multiple characters.
In the present embodiment, the vector graphics file can be svg file.
In the specific implementation, if the vector graphics file is svg file, by xml resolver, svg file is parsed
Text label (<text>label) or text style label (<tspan>label), obtain included character string, and retouch
State the font type and font attribute of the character string.
In the present embodiment, the text information of acquisition includes: character string, the font type of the character string and institute
State the font attribute of character string.
Illustrate below by a specific example, the parsing vector graphics file obtains the realization of text information
Journey.
SVG is used to define the figure based on vector for network.Character string is retouched by<text>label in SVG
It states, the font of character string is described by the font-family of<text>.Following code specifies a font
The passage of " Microsoft YaHei ":
After creating<svg>element,<tspan>element placed in the position of (0,31), the inside includes
Content is the text of character string " Microsoft is refined black ", because x and y are absolute fixs, character string " Microsoft is refined black " is just moved
The left edge in coordinate system is arrived.
It should be noted that SVG text can be wrapped up with<tspan>label, to do whole control to them, about aobvious
Show and positions, the correlation etc. between text fragments.Text in<tspan>is arranged according to inline sequence and they are direct
As being shown in text element.
And after parsing above-mentioned SVG file by xml resolver, by parsing<tspan>label of svg file to obtain
To the text of character string " Microsoft is refined black ", the font- of svg file is got by parsing<text>label of svg file
Family, it may be assumed that the font type Microsoft for describing the character string is refined black.
Step S103 obtains the text information in the default font according to text information described in default font matching
In corresponding font information.
In the present embodiment, the text information according to default font matching, obtains the text information described
Corresponding font information in default font, can realize in the following way: by the default font one by one with the text envelope
Breath is matched, and determines corresponding with the text information default font, and from the determining default font, obtain and
The corresponding font information of the text information.
It should be noted that the font information, comprising: vector value and character pixels amount.
Wherein, the character pixels amount, refers to: in current font, the unitsPerEm (units- of each character
Per-em), it may be assumed that specify " unit " quantity that each em is included, these units can be by other descriptions using indicating
Various length.
Em is for describing relative to the font size applied in currentElement, so it is also relative length unit.One
As browser font size be defaulted as 16px, then 1em==16px；If currently inartificial to the font size of text in row
Setting, then relative to the default font size of browser.
It should be noted that many developers replace pixel using em unit, be used to avoid that text can not be adjusted in IE
This problem of, 1em are equal to current font size, if the font-size of an element is 16 pixels, for this yuan
Element, 1em are equal to 16 pixels.When setting font size, em must be worth can the opposite font size change with father's element.
The vector value is the vector value for the font that font is used to distinguish each kinds of characters font Nei.The arrow
Magnitude is for describing how different fonts are shown.
Continue to use above-mentioned specific example below to illustrate, the text information according to default font matching obtains institute
State the realization process of text information corresponding font information in the default font.
After parsing SVG file by xml resolver, by parsing<tspan>label of svg file to get word
The text of symbol string " Microsoft is refined black " gets the font- of svg file by parsing<text>label of svg file
Family, it may be assumed that describe the character string font type Microsoft it is refined it is black after, the text envelope according to default font matching
Breath, obtains the text information corresponding font information in the default font, specifically comprises the following steps:
Step S103-1, according to the font type of character string described in the text information, in the default font
With corresponding font.
In the present embodiment, the font type of the character string according to the text information, in the predetermined word
Corresponding font is matched in body, can be realized in the following way: after parsing SVG file by xml resolver, being got
The font-family of svg file matches corresponding font in the default font.
Specifically, then matching the default font since the font-family for getting svg file is that Microsoft is refined black
When, it is exactly to find the refined surplus body of Microsoft in the default font.
In the present embodiment, the default font, includes at least: one of opentype, trueType, svg.
It should be noted that the refined surplus body of Microsoft is a kind of font for supporting ClearType technology.It belongs to opentype
Type (suffix is identical as TrueType type font) belongs to sans serif and black matrix in font design.
As a preferred embodiment, executing step S103-1 character string according to the text information
Font type, when matching corresponding font in the default font, if the font type of the character string, in the predetermined word
Matching after then being converted the character string according to preset mode, executes step less than corresponding font again in body
The font type of S103-1 character string according to the text information matches corresponding font in the default font.
It should be understood that due to needing to obtain corresponding font from the default font, so in the character string
Font type when matching is less than corresponding font in the default font, is needed the character string through certain way
Font type is converted into that the font of the default font can be matched.
Step S103-2 encodes the character string in the text information.
In the present embodiment, the character string by the text information encodes, can be using such as lower section
Formula is realized: after xml resolver parses SVG file, the character string got in<tspan>label of SVG file being compiled
Code, is converted to corresponding Unicode for the character string.
Such as: after xml resolver parses SVG file, the character string that will be got in<tspan>label of SVG file "
Microsoft is refined black " each of character encoded, by the character " micro- " be converted to corresponding Unicode be u5fae
u000d\u000a；By the character " soft " be converted to corresponding Unicode be u8f6f u000d u000a；By the word
Symbol " refined " be converted to corresponding Unicode be u96c5 u000d u000a；The word " black " is converted to corresponding
Unicode be u9ed1 u000d u000a.
Step S103-3 obtains the word of the corresponding character string based on the character string after coding in the font
Shape information.
In the present embodiment, the character string based on after coding obtains the corresponding character in the font
The font information of string can be realized in the following way: in the corresponding font being matched in step S103-1, with step
The Unicode obtained in S103-2 is matched, and the font information that the character string is corresponded in the font is obtained.
Such as: the corresponding font being matched in step S103-1 be Microsoft it is refined black, then with u5fae u000d
U000a is inquired in the refined surplus body of the Microsoft, and matching corresponding character is " micro- ", and obtains character " micro- "
Font information.
As a preferred embodiment, corresponding font information is obtained from the default font due to being, so
Before the step of executing acquisition text information corresponding font information in the default font, need to get
The intracorporal whole font informations of the predetermined word, specifically comprise the following steps: to parse the default font, described in acquisition
The font information of each character in default font.
In the present embodiment, described that the default font is parsed, it can realize in the following way: pass through correspondence
The parsing library of the default font parses the default font.
Such as: the type of openType and trueType can be used openType.js and be parsed, the type of SVG
Font is directly read by XML parser.
In the present embodiment, the font information for obtaining each character in the default font, can be using such as lower section
Formula is realized: being directed to each of default font font, is obtained each character in the default font
UnitsPerEm and the corresponding font (Glyph) of each character (charCode).
It should be noted that in the default font that will acquire the font information of each character as font set, with
JSON format is stored.
The default font is parsed with an example below, obtains the font of each character in the default font
The realization process of information is illustrated.
There are 2 kinds of fonts in the default font: " Microsoft is refined black " and " font 2 " (" font 2 " be it is arbitrary its
His font), the key for each font is the font-family of current font.First character section in each font
For the unitsPerEm of the font；All fonts (glyphs) that second field font includes；Key is current in font
The unicode value of the corresponding character of font, the first character section of value are the vector value path of font, and second field is should
The wide advanceWidth of the word of font.
Such as: the font-family of first character body is that Microsoft is refined black, and the first character section in the font is the font
UnitsPerEm:2048；The font 1 that second field font includes, in the refined surplus body of the Microsoft which refers to
Chinese character one；Key in font 1 be 1 it is corresponding Unicode: u0031；The vector value path of font 1 is M320 865L2020
865L2020 689L320 689L320 865Z；The word width of font 1 is 65.
The font information is zoomed in and out deformation by step S105, obtains the information that draws a design of the text information.
In the present embodiment, described that the font information is zoomed in and out into deformation, obtain the drafting road of the text information
Diameter can be realized in the following way: the vector value in the font information being zoomed in and out deformation, obtains the text information
The information that draws a design.
Specifically, described zoom in and out deformation for the font information, the information that draws a design of the text information is obtained,
Include the following steps:
Vector value in the font information is zoomed in and out into deformation；
The vector value of the font information after scaling is drawn into the font as in the vector graphics file
The information that draws a design of information.
It should be understood that it is of different sizes due to the font information and the font of the vector graphics file, so root

The vector value by the font information zooms in and out, and specifically comprises the following steps:
According to the character pixels amount in the font size of the character string, with the font information, amount of zoom is obtained；
Based on the amount of zoom, the vector value of the font information is zoomed in and out.
In the specific implementation, the font size according to the character string, with the character pixels in the font information
Amount obtains amount of zoom, by the font size of the character string divided by the character pixels amount in the font information, obtains amount of zoom
scale。
Continue to use above-mentioned specific example below to illustrate.
Referring to FIG. 4, showing the schematic diagram of the scaling and migration process that provide according to an embodiment of the present application.
SVG is used to define the figure based on vector for network.Character string is retouched by<text>label in SVG
It states, the font of character string is described by the font-family of<text>.Following code specifies a font
" Microsoft YaHei ", the passage that font size is 204:
Since the font size of the character string is 204, the character pixels amount in the font information is 2048, so will
The font size 204 of the character string obtains amount of zoom scale0.1 divided by the character pixels amount 2048 in the font information.
It is described to be based on the amount of zoom after getting the amount of zoom scale, to the vector value of the font information
Deformation is zoomed in and out, can be realized in the following way: to each start-stop point in the vector value of the font information, according to institute
It states amount of zoom and zooms in and out deformation.
It continues to use above-mentioned specific example below to illustrate, to each start-stop point in the vector value of the font information, presses
The realization process zoomed in and out according to the amount of zoom.
Referring to FIG. 4, it illustrates the definition provided according to an embodiment of the present application for drawing the font information
The schematic diagram of drawing path.
The vector value path of the font information is 689 L320 of M320 865L2020 865L2020 689L320
When 865Z, refer to: the font information starts from position (320,865) and draws straight line in-position (2020,865), draws later straight
Line in-position (2020,689), then straight line in-position (320,689) are drawn, finally in (320,865) Turn Off Path.
And it is based on the amount of zoom, to each start-stop point in the vector value of the font information, according to the amount of zoom
It is to be directed to the amount of zoom scale0.1 every in the vector value of the font information when realization process zoomed in and out
One start-stop point zooms in and out, it may be assumed that (320,865) * scale0.1；(2020,865) * scale0.1；(2020,689) *
scale0.1；(320,689) * scale0.1；(320,865) * scale0.1 finally obtains the font information after scaling
Drawing path is<path>: 86 L202 of M32 86L202,68 L32,86 L32 86Z.
Since the character string in the vector graphics file may have initial position in a coordinate system, so parsing
When the vector graphics file, the font attribute of the character string, it is also possible to including coordinate information.So described to the word
Shape information is after vector value zooms in and out deformation, it is also necessary to according to the coordinate information, to the font information after scaling
Drawing path deviated.

Fixed coordinate position；Instruction C is for drawing shellfish match curve three times；Instruction Q is for drawing secondary shellfish match curve；Instructing Z is
For Turn Off Path.
It is 865 L2020 of M320,865 L2020,689 L320 689 in the vector value path of the font information
When L320 865Z, since the vector value path of the font information has one group of M instruction, three groups of L instructions, so in execution
When stating algorithm, need to bring one group of M instruction into M (x, y)=(x+ (cmd.x*scale), y+(- cmd.y*scale)), by three
3 L (x, y)=(x+ (cmd.x*scale), y+ (- cmd.y*scale)) is brought in group L instruction into respectively, obtains definition for drawing
Make the drawing path of the font information.
It should be understood that instruction Q and instruction C are used when being for drawing shellfish match curve three times and secondary shellfish match curve
Instruction, in the above example due to having only used straight line instruction L when drawing, so above-metioned instruction Q and instruction C is not used.
When using instruction Q and instruction C, it is only necessary to bring in instruction Q and instruction C corresponding parameter into, repeat no more again.
Since the character string in the vector graphics file may have initial position in a coordinate system, so described
After defining the drawing path for drawing the font information, the coordinate information is deviated based on the amount of zoom, is obtained
Take the location information for drawing the font information.

According to the coordinate information, the wide diameter of word of the font information after scaling is deviated.
Specifically, can be obtained using following algorithm when obtaining the location information for drawing the font information and draw institute
State the location information of font information:
(nx, ny)=(x+advanceWidth*scale, y)
Wherein, (nx, ny) is the location information for drawing the font information；AdvanceWidth refers to the font information
Word it is wide；(x, y) refers to the initial position message of character string in a coordinate system.
Such as: the word width of the font information is 650, is carried out based on the amount of zoom scale0.1 wide to the word 650
After scaling, the word width is 65, further according to the coordinate information (0,31) to the wide diameter of word of the font information after scaling into
Line displacement, obtaining and drawing the location information of the font information is (65,31).
