Abstract

The invention discloses a method for calculating the display width of characters in a dot matrix character library. The method is characterized by comprising the following steps: a. starting (introducing character strings); b. recording and displaying a left-side position abscissa x1; c. displaying the characters; d. taking a first character and calculating the width w of the character; e. the display position abscissa of the character X1 is equal to x1 plus w; and f. judging whether the inputting of the character string is ended. The invention discloses a method for calculating the display width of characters in the dot matrix character library, which solves the problems of interface display faced when equal-width character libraries are used for displaying unequal-width characters. The most suitable display position of each dot matrix character is calculated by judging the actual display width thereof so as to achieve the purpose of compact and beautiful display of characters.

Description

A kind of method of calculating dot matrix word library font display width

Technical field:

The present invention relates to the technical field of mobile communication, refer to when carrying out display string a kind of display width computing method of being out of shape font especially with dot matrix word library.

Background technology:

Dot matrix word library applies to numerous demonstrations to font in the higher platform of rate request.Divide by storage mode, horizontal delivery can be arranged, the many kinds of vertical delivery or the like, but generally speaking, be to represent font display part and blank parts respectively with 1 and 0.

For convenience of understanding, the dot matrix word library that the present invention write uses 1 expression display element, the blank pixel of 0 expression, and storage format is with the behavior element, and per 8 picture elements gather into a byte, and the mode with back benefit 0 of 8 picture elements of less than is gathered into a byte.Like this, the width of each font just must be the same, and for some West Europe font, this dot matrix word library can't reach and show requirement attractive in appearance.

Summary of the invention:

The object of the present invention is to provide a kind of method of calculating dot matrix word library font display width, thereby each raster font calculates only display position by judging its actual display width, show compact to reach font, beautiful purpose has overcome the shortcoming and defect that exists in the prior art.

To achieve these goals, technical scheme of the present invention is: a kind of method of calculating dot matrix word library font display width is characterized in that: described step is:

A, beginning (importing character string into);

B, record show leftward position x1;

C, character display;

D, get first character, calculating character width w;

E, CSD horizontal ordinate X1=x1+w;

F, judge character string whether finish the input.

The invention discloses a kind of method of calculating dot matrix word library font display width, solved the interface display problem that is faced when showing monospaced font not with wide character library.Thereby each raster font calculates only display position by judging its actual display width, shows compactness, beautiful purpose to reach font.

Description of drawings:

Fig. 1 is the single character duration calculation flow chart of example of the present invention.

Fig. 2 is the character string display process flow diagram of example of the present invention.

Embodiment:

With reference to the accompanying drawings, the present invention further is described

The present invention is a kind of method of calculating dot matrix word library font display width, and it is different from prior art and is: described step is:

A, beginning (importing character string into);

B, record show leftward position horizontal ordinate x1;

C, character display;

D, get first character, calculating character width w;

E, CSD horizontal ordinate X1=x1+w;

F, judge character string whether finish the input.

2, a kind of method of calculating dot matrix word library font display width according to claim 1, it is characterized in that: the flow process substep of steps d is:

1. begin (importing word-base data into);

2. write down original width W=0;

3. get delegation's dot array data, last is 1 some picture element number m to the right side to calculate the left side;

4. whether differentiate m greater than W, if m＞W, W=m then, then dot character finishes then, if m≤W, then directly dot character finishes.

This method need interdependently realize in the cell phone software of integral body.

One, single character duration calculating is an independently module, provides several public interface functions, for other module invokes.

Two, when use is of the present invention, carry out the demonstration of character string according to Fig. 2 flow process.

Three, step: please refer to Fig. 2, when needing display string, preserve the horizontal ordinate position in character string display zone earlier, when having shown a character at every turn, according to the width of the flow process calculating character of Fig. 1, and then the demonstration horizontal ordinate position of calculating character late according to the flow process of Fig. 2.

Being preferred embodiment of the present invention only in sum, is not to be used for limiting practical range of the present invention.

Claims (2)

1. method of calculating dot matrix word library font display width, it is characterized in that: described step is:

A, beginning (importing character string into);

B, record show leftward position horizontal ordinate x1;

C, character display;

D, get first character, calculating character width w;

E, CSD horizontal ordinate X1=x1+w;

F, judge character string whether finish the input.

2. a kind of method of calculating dot matrix word library font display width according to claim 1 is characterized in that: the flow process substep of steps d is:

1. begin (importing word-base data into);

2. write down original width W=0;

3. get delegation's dot array data, last is 1 some picture element number m to the right side to calculate the left side;

4. whether differentiate m greater than W, if m＞W, W=m then, then dot character finishes then, if m≤W, then directly dot character finishes.
