Abstract
The invention provides a vector italic character reversing method which comprises the following steps: 1) acquiring display width, actual width and character height of characters to be reversed; 2) scribing according to the display width, actual width and character height in the step 1); and 3) determining the parallelogram reversing region of the vector italic character according to the scribing. In the vector italic character reversing method, the reversing region is correspondingly adjusted into a parallelogram according to the inclination angle of the vector italic characters, so that the italic vector characters are completely contained in the reversing region.
Description
Technical field
The present invention relates to the anti-whitening method of vector italics on a kind of electronic equipment, relate in particular to the method that the anti-white region of vector italics is confirmed at a kind of angle of inclination through the vector italics.
Background technology
In the electronic equipment, like portable equipments such as electronic dictionary, mobile phone, PDA, the anti-white region of vector italicized character is the same with non-italicized character at present, all is rectangle.So just exist the character of anti-white region starting and ending position can not be comprised in the situation in the anti-white region fully, referring to Fig. 1.
Summary of the invention
In order to solve existing technical matters in the background technology; The present invention proposes a kind of anti-whitening method of vector italics; Angle of inclination according to the vector italics is adjusted into a parallelogram accordingly with anti-white region, makes complete being comprised in the anti-white region of italic vector font.
Technical solution of the present invention is: a kind of anti-whitening method of vector italics, and its special character is: said method comprising the steps of:
1) obtains display width, developed width and the character height that needs reverse characters;
2) according to display width, developed width and the character height of step 1), rule;
3) confirm the anti-white region of parallelogram of vector italicized character according to ruling;
Above-mentioned steps 2) concrete steps are:
2.1) supposition needs horizontal ordinate x, the ordinate y of the reference position of reverse characters;
2.2) from (x, y) position begins to (x+a, y) line;
2.3) from (x0 is y-1) to (x0+a, y-1) line;
2.4) repeating step 1.2) and step 1.3), every standardized line scribing position ordinate subtracts 1 unit;
2.5) to (x0, y-(hi-1)), when (x0+a, y-(hi-1)), (hi is the lines that will draw the height of character altogether, and since 0 calculating, the last item line is hi-1) finished line.
Above-mentioned steps 3) concrete steps are: calculate the position of the x0 of each line, calculate through following formula according to the proportional principle in the limit of similar triangles: x0=x+ (b-a) * n/ (hi-1);
Wherein n representes to draw is which bar line (calculate since 0, the last item line n is hi-1).
The present invention comes the anti-white region of compute vectors italics through the angle of inclination of compute vectors italics.Angle of inclination according to the vector italics is adjusted into a parallelogram accordingly with anti-white region, makes complete being comprised in the anti-white region of italic vector font.

Fig. 2 is the synoptic diagram of display width, developed width and the character height of reverse characters;
Fig. 3 .1-Fig. 3 .2 is a specific embodiment synoptic diagram of the present invention;
Embodiment
Referring to Fig. 1, Fig. 2, the present invention comes the anti-white region of compute vectors italics through the angle of inclination of compute vectors italics.Angle of inclination according to the vector italics is adjusted into a parallelogram accordingly with anti-white region, makes complete being comprised in the anti-white region, referring to Fig. 1 of italic vector font;
The present invention is a kind of anti-whitening method of vector italics, may further comprise the steps:
Referring to Fig. 2, a is a display width; B is a developed width; Hi is a character height;
1) obtains display width, developed width and the character height that needs reverse characters;
2) according to display width, developed width and the character height of step 1), rule;
2.1) supposition needs horizontal ordinate x, the ordinate y of the reference position of reverse characters;
2.2) from (x, y) position begins to (x+a, y) line;
2.3) from (x0 is y-1) to (x0+a, y-1) line;
2.4) repeating step 1.2) and step 1.3), every standardized line scribing position ordinate subtracts 1 unit;
2.5) to (x0, y-(hi-1)), when (x0+a, y-(hi-1)), (hi is the lines that will draw the height of character altogether, and since 0 calculating, the last item line is hi-1) finished line.
3) confirm the anti-white region of parallelogram of vector italicized character according to ruling; Calculate the position of the x0 of each line, calculate through following formula according to the proportional principle in the limit of similar triangles: x0=x+ (b-a) * n/ (hi-1).
