Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
One of core idea of the embodiment of the invention is, adopts a certain font size drafting character string earlier, if the character string of being drawn in the size of target area, is then thought this font size " suitably ", otherwise is " inappropriate ".In this case, the purpose that the present invention adjusts font size is, constantly attempts drawing, up to the maximum appropriate value that finds to be no more than initial font size.The process of attempting drawing makes font size attempt drawing between the variable font size lower limit and the variable font size upper limit exactly, and brings in constant renewal in the described variable font size lower limit and the variable font size upper limit, dwindles its scope.Make font size not in this scope between variable font size lower limit and the variable font size upper limit when once adjusting, to get final product the ends drawing process, to obtain suitable font size.
With reference to figure 1, show of the present invention a kind of in the target area process flow diagram of the method embodiment of drafting character string, specifically can may further comprise the steps:
Whether the character string that step 103, judgement are drawn surpasses the size of described target area; If then execution in step 104; If not, execution in step 105 then;
Rendering character strings result in step 107, the described target area of preservation.
Font size described in the present invention is the attribute of a font descriptor in the various computer systems, also can be called font size, font generally includes font name (being called for short font usually, as the Song typeface, regular script etc.), font size, pattern information such as (runic, italics).The unit of font size is pt (pound), and 1pt equals 1/72 inch, and in the reality, to define such as a word, No. two words etc., this " * word " can convert to pt is the numerical value of unit to Chinese usually, and for example, No. five words are 10.5pt.In the present embodiment, font size, the font size of system default or the font size of other initial setting up etc. that described reference type size can preset for the user at first, in the process of repeatedly drawing, described reference type size can also be adjusted font size, for example, when dwindling font size for the second time, it is the primary font size that dwindles as the reference type size that dwindles foundation.
In the present embodiment, described target area can be the Drawing Object of creating in buffer memory, and the height and the width of this Drawing Object are fixed.When attempting drawing according to various font sizes, can create the drafting that such buffer memory Drawing Object is used for character string at every turn; When upgrading variable font size lower limit (being current optimal criteria font size), also can remain corresponding buffer memory Drawing Object, so that when output string, directly use the result of this buffer memory Drawing Object.
In described target area, in the drafting character string, promptly can be regarded as in the corresponding coordinate position of described Drawing Object draw characters, for example, a kind of in the target area process of drafting character string be:
Create the buffer memory Drawing Object of a specified altitude assignment and width, it is 0 that the X coordinate is set, and the Y coordinate is ascent, during drafting, gets i character in the character string successively, X displacement character duration; If the character of being drawn is the line feed identifier, perhaps, when the displacement of institute's draw characters surpasses the width of described Drawing Object, then X is put 0 again, it is high that Y is moved to next row; If Y+descent has surpassed the height of this Drawing Object, then the size of the expression character string of being drawn has surpassed the size of this Drawing Object, has promptly exceeded the magnitude range of target area.
Wherein, ascent and descent are the attributes that each character all has, and ascent is that character exceeds the distance on the baseline (baseline); Descent is that character exceeds the following distance of baseline.Baseline is meant that (x, when y) locating, the placement of this character can make its invocation point (specific location point that standard is provided with) also be placed on this position when program is placed on certain coordinate with character.Invocation point specifies a horizontal line promptly to be called the baseline of character, and character keeps horizontal alignment by baseline.Row is high: the height that a line character is shared.It is mensurable to be distance between the baseline of adjacent line of text.It is the summation of standard line space (leading), ascent, descent.For font of determining and font size, ascent, descent are the maximal values of determining, the row height also can be determined thereupon.
Thereby in the present embodiment, described determining step 102 may further include following substep:
If the character that substep A1 drew is the line feed identifier, then be moved to capable high this character of drawing of the next one of described target area;
Substep A2, judge that whether the height of institute's drafting character string surpasses the height of described target area, if, judge that then the character string of being drawn surpasses the size of described target area, if not, judge that then the character string of being drawn does not surpass the size of described target area.
Perhaps, can comprise following substep:
If the displacement of substep B1 institute draw characters surpasses the width of described target area, then be moved to capable high this character of drawing of the next one of described target area;
Substep B2, judge that whether the height of institute's drafting character string surpasses the height of described target area, if, judge that then the character string of being drawn surpasses the size of described target area, if not, judge that then the character string of being drawn does not surpass the size of described target area.
Certainly, those skilled in the art as required or the experience character string that adopts other determination methods to judge the to be drawn size that whether surpasses described target area all be feasible, the present invention does not need this to limit.
Be understandable that,, in the target area, all can occupy a fritter area for each character, thereby, one of another design in the embodiment of the invention is, generates the rule that font size is adjusted by the calculating to area, and described regulation rule comprises the rule of dwindling font size and amplifying font size.Particularly, for font size f, the width of each character fluctuates at D, and f and D are directly proportional (may have error owing to reason such as rounding) substantially, and there is similar relation in font size too with the row height.To this, can think that for font size f, each character can occupy D
2Area.
In this case, the length of supposing character string is n, and this is changeless.So, press
The shared total area drawn in font size is nD
2In the character drawing process, width always immobilizes, so can obtain nD
1 2/ h
1=nD
2 2/ h
2, i.e. f
1 2/ h
1=f
2 2/ h
2, font size square with highly be directly proportional.
Based on above-mentioned analysis, in the process of attempt drawing, when the size of target area enough put down in all character strings have the character of this font size the time, the rule of amplifying font size can be shown in following formula:
newSize＝oldSize*sqrt(height/y)
Wherein, the target font size of newSize for amplifying; OldSize is current reference type size, and for example, if amplify font size for the first time, then reference type size may be the font size of user's initial setting up; If amplify font size for the second time, then reference type size is the font size after amplifying for the first time; Sqrt () is the function of extraction of square root; Height is the height of target area; Y is the displacement on the Y coordinate, is equivalent to the height that takies when drawing by oldSize.Height is greater than Y, so the font size that calculates is to become big.In addition, for ease of calculating, can also round up to result of calculation.
Correspondingly, in the process of attempt drawing, when the size of target area was not enough, Y approached to equal height, and, may be certain character (being assumed to be i) that is plotted to character string and the traversal circulation is forced to interrupt.In this case, can think then that i character occupied Y,, continue to draw that n character will occupy height H=y/i*n altogether according to this font size if highly do not limit, i.e. y/H=i/n, aspect ratio is similar to the character number ratio.Therefore, can obtain dwindling the rule of font size, shown in following formula:
newSize＝oldSize*sqrt(i/n)
Wherein, the target font size of newSize for amplifying; OldSize is current reference type size, and for example, if amplify font size for the first time, then reference type size may be the font size of user's initial setting up; If amplify font size for the second time, then reference type size is the font size after amplifying for the first time; Sqrt () is the function of extraction of square root; I is the number of institute's draw characters; N is the actual characters number of described character string.Simultaneously, can also round downwards the result.
Thereby in the present embodiment, described step of dwindling reference type size can comprise following substep:
Substep C1, according to the actual characters number of described character string and the draw characters number calculate coefficient of reduction;
Substep C2, described reference type size is dwindled according to described coefficient of reduction.
The step of described amplification reference type size can comprise following substep:
Substep D1, according to the height of described target area and the high computational amplification coefficient of institute's drafting character string;
Substep D2, described reference type size is amplified according to described amplification coefficient.
Before drafting, according to the design that above-mentioned area calculates, can obtain one equally and connect and be bordering on the font size of target, attempt the number of times drawn to reduce.Thereby, before trial is drawn, can also comprise step:
Adjust described reference type size.
By carrying out described step, can do once estimation process fast to reference type size, thereby obtain an approaching relatively target font size, method for described adjustment, by any employing of those skilled in the art all is feasible, for example, the fixing coefficient of adjusting is set, each adjustment all reduces a font size; Perhaps, according to the size of target area and the length of character string the adjustment coefficient being set, all is feasible by this this reference type size of adjustment coefficient adjustment etc., and the present invention does not need this to limit.
Preferably, in the present embodiment, can adjust described reference type size by following substep:
Substep S101, judge whether described reference type size is less than or equal to 0, if then carry out substep S102; If not, then from substep S103 execution subsequent step;
Substep S102, described reference type size is put 0;
Substep S103, the overall width that obtains character string and row are high;
The capable height of the overall width of described character string and described reference type size may pass through JDK (JavaDevelopment Kit, the Java developing instrument) API (application programming interfaces, ApplicationProgramming Interface) obtains, can adopt other method of the prior art to obtain, the present invention does not limit this yet.
Substep S104, according to the overall width of described character string and the mean breadth of actual characters number calculating character;
Substep S105, according to the mean breadth of described character and the high average unit area of calculating described character of row;
Substep S106, calculate the total area of target area, the average unit area of the described total area and described character is compared, obtain the held character number of described target area;
Substep S107, judge that whether the described character number that holds is more than or equal to described actual characters number, if then carry out substep S108; If not, then carry out substep S109;
Substep S108, keep described reference type size;
Substep S109, generate and adjust coefficient according to described character number and the actual characters number held, and according to the described reference type size of described adjustment coefficient adjustment.
In the present embodiment, for realizing the purpose of Fast estimation, the adjustment process of described reference type size is for only turning uncomfortable big unidirectional adjustment process down, in addition, high consuming time of the width of the API calculating character string by adopting JDK and row is very little, can effectively economize on resources.Certainly, those skilled in the art as required or experience to adopt other method of adjusting font size all be feasible, the present invention does not need this to limit.
For making those skilled in the art understand the present invention better, below specify the process of described adjustment reference type size by way of example:
The size in hypothetical target zone is 80*60, and the number of character string is 10, and reference type size is 24; The first step is judged described reference type size greater than 0, and then to obtain the overall width of described character string be 240 to the API by JDK, and the row height is 27.375;
In second step, the mean breadth that calculates character is: 240/10=24;
In the 3rd step, the average unit area that calculates character is: 24*27.375=657;
In the 4th step, the total area that calculates the target area is 80*60:4800;
In the 5th step, the average unit area of the described total area and described character is compared: 4800/657 ≈ 7;
In the 6th step, the held character that obtains in the described target area is 7;
The 7th step, judge the described character number 7 that holds less than described actual characters number 10, then according to described character number and the actual characters number generation adjustment coefficient that holds be: sqrt (7/10) ≈ 0.84;
The 8th step, according to the described reference type size of described adjustment coefficient 0.84 adjustment be: 24*0.84 ≈ 20.
Very little when the target area, so that can't hold an average word when wide, or when failing to lay down delegation, can also in above-mentioned adjustment process, increase scaled step, with reference to figure 2, show the process flow diagram of another kind of font size method of adjustment of the present invention, specifically can may further comprise the steps:
Whether step 201, judgment standard font size size are less than or equal to 0, if, then size is changed to 0, if not, then carry out next step;
The overall width of described average character duration avgW=character string/actual characters number;
For further specifying the present invention, with reference to figure 3, show and use the process flow diagram that the preferred embodiments of the present invention are carried out the rendering character strings in the target area, specifically can may further comprise the steps:
High wide buffer memory Drawing Object is specified in step 304, one of establishment, and the x coordinate puts 0, and the y coordinate is Ascent; At this moment, toTry=false; BreakLoop=false;
Step 307, judge whether to run into newline or x exceeds peak width, if then carry out next step; If not, then in (x, y) the position draw characters of buffer memory Drawing Object;
Step 310, whether judge current reference type size less than the described variable font size upper limit, if then execution in step 311, if not, then execution in step 312;
Whether step 314, judgement circulation are interrupted, and breakLoop==false is if then carry out next step; If not, then the expression circulation is interrupted, returns step 303 and rejudges;
Step 316, upgrade described variable font size lower limit, and write down corresponding buffer memory Drawing Object, continue to carry out next step with the value of current reference type size;
As can be seen, the present invention is drawing initially from last example, can do once estimation fast earlier, to adjust reference type size, makes the ideal font size of its relatively more approaching final acquisition; The loop structure of each character of traversal character string has two outlets, and primary outlet is normal loop ends, and second outlet is for forcing to finish outlet.In drawing process, the condition of amplifying font size can also be set, height in the last example takes 90% and whether only is used for for example, it all is feasible that those skilled in the art are provided with any condition, the present invention does not limit this, this condition setting can reduce the number of times of attempting drafting effectively, thereby effectively improves the drafting efficient of character string.
