Embodiment
For problems of the prior art, two kinds of content of text typesetting schemes are proposed in the present invention, wherein in scheme one, pre-estimate the number of characters that terminal screen lastrow can show at most, and according to estimated result and actual conditions, the actual number of characters that can show of each row is adjusted; In scheme two, for each character in character string to be shown, when determining its width, first determine its type, and adopt different width determination modes according to the difference of type, comprise GDI mode and non-GDI mode.No matter adopt which kind of scheme, all avoid and all utilize GDI to determine its width for each character, thus improve typesetting efficiency.
For make technical scheme of the present invention clearly, understand, to develop simultaneously embodiment referring to accompanying drawing, scheme of the present invention be described in further detail.
Fig. 1 is the process flow diagram of content of text composition method first embodiment of the present invention.As shown in Figure 1, comprise the following steps:
Step 11: estimate the number of characters charcount that terminal screen lastrow can show at most.
In actual applications, available onscreen width is divided by the width of a designated character, if result of calculation is integer, then using result of calculation as described charcount, otherwise, result of calculation is rounded rear as described charcount downwards.
Described designated character can be a certain character in character string to be shown, as first character, or, may not be a certain character in character string to be shown, but the character that is fixing, " state " word of such as " China ".
If result of calculation is not integer, be such as 10.2 or 10.8, so, the overall width in line with a line character of actual displayed can not be greater than the principle of screen width, needs result of calculation to round (10) downwards; Certainly, if result of calculation is integer just, then without the need to rounding downwards.
Step 12: utilize GDI to determine the overall width of front charcount character in character string to be shown, and determine whether described overall width equals screen width, if so, then performs step 13, otherwise, perform step 14.
Suppose that the value of charcount is 10, so conventionally, GDI directly can being utilized to obtain the overall width of these 10 characters, without the need to determining the width of 10 characters respectively, being then added.
Step 13: a front charcount character is shown on terminal screen as a line, then using the remaining character string do not shown as character string to be shown, repeated execution of steps 12.
Step 14: the value of charcount is adjusted, obtain charcount ', before occurring, the overall width of the individual character of charcount ' is less than or equal to screen width, when the overall width of front charcount '+1 character is greater than the situation of screen width, individual for front charcount ' character is shown on terminal screen as a line, then using the remaining character string do not shown as character string to be shown, repeated execution of steps 12.
Wherein, when the overall width of character string to be shown is less than screen width, character string to be shown is shown on terminal screen as a line, process ends.
In actual applications, if the overall width of a front charcount character is greater than screen width, so value of adjustable charcount, obtain charcount ', as made charcount '=charcount-1, if the overall width of the individual character of front charcount ' is still greater than screen width, adjustment can be continued, as made charcount '=charcount '-1; Otherwise, if the overall width of a front charcount character is less than screen width, so can make charcount '=charcount+1, if the overall width of the individual character of front charcount ' is still less than screen width, adjustment can be continued, as made charcount '=charcount '+1; Once the overall width of the individual character of charcount ' is less than or equal to screen width before occurring, the overall width of front charcount '+1 character is greater than the situation of screen width, then can stop adjustment, and individual for front charcount ' character is shown on terminal screen as a line, how to be shown as prior art.
Said process can be exemplified below:
Suppose in character string to be shown, to comprise 32 characters altogether, the value of the charcount estimated is 10, so, first the overall width of 1st ~ 10 characters in character string to be shown is determined, and this overall width and screen width are compared, if both are just equal, so direct 1st ~ 10 characters are shown on terminal screen as the first row, otherwise (supposing to be this situation in this example), the value of charcount is adjusted, suppose to meet the requirements when being adjusted to 12, then 1st ~ 12 characters are shown on terminal screen as the first row, afterwards, for 13rd ~ 32 characters, determine the overall width of front 10 characters wherein, suppose, by comparing and adjusting, 13rd ~ 21 characters to be shown on terminal screen as the second row, in addition after, for 22nd ~ 32 characters, determine the overall width of front 10 characters wherein, suppose, by comparing and adjusting, 22nd ~ 29 characters to be shown on terminal screen as the third line, finally, 3 remaining characters are shown on terminal screen as fourth line, process ends.
Fig. 2 is the process flow diagram of content of text composition method second embodiment of the present invention.As shown in Figure 2, comprise the following steps:
Step 21: for each character in character string to be shown, determine type belonging to it respectively, described type comprises: Chinese character type, ASCII(American Standard Code for information interchange) (ASCII, American Standard Codefor Information Interchange) type and other type; If Chinese character type or ASCII type, then utilize non-GDI mode to determine its width, if other type, then utilize GDI to determine its width.
Step 22: be shown on terminal screen according to the width of each character determined by described character string branch, the overall width of the character in every a line is all less than or equal to screen width.
In actual applications, step 21 and 22 may be executed in parallel, and representation shown in Fig. 2 only in order to express easily.
The present embodiment is compared with existing type-setting mode, and difference is only that the mode determining character duration is different, and other identical part repeats no more.
In the present embodiment, for each character, first determine its type, comprise Chinese character type, ASCII type and other type.As a rule, each character is by multiple, and as 16 bit compositions, front several bit wherein, if front 2 or front 3 bits are for identifying the type of this character, so, can determine its type according to bit several before each character.
For the character of Chinese character type, its width is fixing, and this natural width is its width; For the character of ASCII type, although its width is not fixing, its width is clearly determined, therefore, a form can be pre-set, in this form, preserve each self-corresponding width of different ASCII type characters, by inquiring about this form, the width of required character can be obtained; For the character of other type, can, according to existing mode, utilize GDI to obtain its width.
