Embodiment
After the present invention produces the single line structure of font, adjust the thickness of this each stroke of font again, show high-quality little font to reach.
At first, obtain the starting point (initial point) and end point (end point) of the single line structure of each stroke.Utilize the font data in the existing group word technology, (it is not blacking in the housing as stroke housing font (its be in the housing at least partly the stroke of blacking) or pure housing font, and the stroke of housing is only arranged), these fonts can be adjusted its size, in general, approximately use 300 to 500 strokes can organize out the font data of a cover traditional Chinese.The thickness of these strokes is set at zero and draw, can obtains the single line structure of stroke, how to choose the starting point and the end point of the single line structure of stroke, after detailed explanation is arranged.
See also Fig. 6; Fig. 6 is stroke a " one's " frame structure, because when drawing stroke housing font, the stroke program of prior art can be according to the key point and the width value of this stroke, calculate the curve of frame structure, as long as the thickness of stroke is non-vanishing, then the frame structure of stroke must be a closed curve, and therefore the direction from an A along arrow is drawn out the frame structure of Fig. 6.See also Fig. 7; Fig. 7 is zero synoptic diagram for stroke weight among Fig. 6.If the thickness of stroke is made as zero, the drawing path of prior art be to draw to a C from a B, again from a C to a B drafting, no matter thickness is why, the drafting mode of the stroke program of prior art is that each stroke is considered as a closed curve.The starting point that the present invention sets this stroke according to the single line structure of Fig. 7 is B and end point is C.Therefore draw as during the single line structure of Fig. 7 when the present invention uses the stroke program, the stroke program only according to key point originally and the starting point B and the end point C that set, stops just being plotted to a C from a B, can not go back to a B drafting from a C again.
In the present embodiment, the starting point of most of strokes is first key point of this stroke, and the end point of most of strokes is last first key point of this stroke.The starting point of all the other strokes and end point then are by artificial definition.See also Fig. 8 to Figure 10.Fig. 8 is a non-directional stroke, and the direction from a D along arrow is drawn.The thickness of the stroke of Fig. 8 being made as zero, can obtaining the single line structure of Fig. 9, is the bilateral curve that zero non-rectilinear stroke is still wanted calculating chart 8 frame structures because prior art is drawn thickness, so the interior curve of dotted portion can not overlap and is single curve.Therefore when the present invention draws the single line structure of this non-rectilinear stroke, the stroke program can be according to key point originally and the starting point E and the end point F that set, be plotted to a F from an E and just stop, can obtaining the single line structure of Figure 10, therefore solved the nonoverlapping problem of curve among Fig. 9.
See also Figure 11; Figure 11 is the synoptic diagram of the single line structure of each font that the present invention draws out.Then, promptly finish the drafting of font as long as adjust the thickness of each stroke in each font.Adjust stroke weight following several mode is arranged.
See also Figure 12; Figure 12 is for adjusting the synoptic diagram of stroke weight.Stroke among Figure 12 for some G to the straight line stroke of putting H, turn right, down and turn right down and extend other three points (is mark with " fork ") to putting each point that H was comprised (is mark with the stain) with a G, the width that promptly draws is 2 a font.Utilize the mode of extending to adjust the thickness of stroke, width that is extended and direction can be decided according to required font size.
See also Figure 13; Figure 13 is for adjusting the synoptic diagram of stroke weight.Stroke among Figure 13 is the center of circle with an I to putting each point that J was comprised for putting I to the straight line stroke of putting J, and the distance between 2 is that radius is drawn filled circles, and the width that promptly draws is 2 a font.Adjust the thickness of stroke in the mode of drawing filled circles, choosing then of radius decided on required font size.
See also Figure 14; Figure 14 is for adjusting the synoptic diagram of stroke weight.Stroke among Figure 14 for some K to the straight line stroke of putting L, divide benchmark with a K into to the ruling pen of putting L, extend downwards in gray-scale value mode decrescence.Utilize different gray-scale value sizes to show font, gray-scale value degree and width decrescence decided by required font size.
See also Figure 15 and Figure 16, be respectively the synoptic diagram of adjusting the font behind the stroke weight in the mode of Figure 12 and Figure 14.Figure 15 and Figure 16 show that the quality of little font is better than the display quality of Fig. 5, therefore can improve the display quality of little font by the present invention.The mode that the present invention adjusts stroke weight is not limited to above-mentioned mode, and the method that other any adjustable lump-sums are drawn thickness is also adopted by the present invention.
When a display system shows font at a display screen, can judge the size of font earlier, if belong to big font, then select the group word technology of prior art to draw big font; If belong to little font, then select of the present invention group of word technology to draw little font, to promote the display quality of little font.Needing the complex form of Chinese characters of the data volume of 1.2MB with a cover with prior art is example, need increase the starting point and the end point data of each stroke when drawing the small character type owing to the present invention, so the big appointment of this display system increases the data volume of 1.2KB (byte).
Perhaps, no matter the size of font is all drawn with of the present invention group of word technology, therefore must not store the width value of original each stroke, just the width value in Fig. 3 data structure 24.See also Figure 17 to Figure 19, Figure 17 is the stroke data structure of wanting 44 required for the present invention; Figure 18 is the synoptic diagram of the stroke table of comparisons 40 of the present invention; Figure 19 describes the synoptic diagram of shelves 48 for font of the present invention.Do not have this item number certificate of width value in the stroke data structure 44 of Figure 17 and the stroke description list 42 of Figure 19, therefore whole data volume can be reduced to 1.0-1.1MB from the 1.2MB of previous technology.
In addition, the present invention only need calculate the monolateral curve of stroke housing font originally, and uses easy mode to adjust stroke weight, calculates point in the closed curve compared to prior art, and the speed that the present invention produces font can significantly promote.
See also Figure 20; Figure 20 draws the process flow diagram of font for the present invention, and step is as follows:
Step 100: judge font size to display earlier, if big font then enters step 104; If little font then enters step 102;
Step 102: according to the font sign indicating number WID of this font, obtain corresponding stroke description list 42, according to starting point 46, end point 47, key point and the stroke program of each stroke in the stroke description list 42, draw out the single line structure of this font again, then enter step 106;
Step 104: use the group of strokes word technology of prior art, draw out the housing of this font, then enter step 108;
Step 106: adjust the thickness of each stroke in this font, then enter step 110;
Step 108: utilize the blacking program with this font blacking, then enter step 110;
Step 110: export this font, finish.
Certainly, Figure 20 also can omit step 100, and all fonts are all drawn font with method for drafting of the present invention.
The invention provides a kind of method that produces font, the stroke program is drawn out the single line structure of stroke according to key point, starting point and the end point of stroke, treat that whole font single line structure is completed after, the thickness of adjusting each stroke again gets final product.Advantage of the present invention has: the data volume of required increase is little, about 1.2KB, and the speed that produces font is fast, and the display quality height of little font.In addition, the present invention not only can be applicable to Chinese font, and other structural figures are also applicable.
