Specific embodiment
Below in conjunction with the accompanying drawings, the amplification that a kind of raster font based on conversion vector of present invention offer is discussed in detail shows
Method and amplification/display device.
The amplification of raster font is based on graphics proportion and amplifies.Chinese character, when small font transforms to big font, keeps profile knot
Structure constant that is to say, that amplify Chinese character when to keep symmetrical above and below about Hanzi structure.
Before implementing the raster font amplification display method that the present invention provides, need to execute an initialization step, including：
It is (X according to prestoring sizing reallys,Ys) dot matrix word library and target font dot matrix (Xt,Yt), that is, amplify font dot matrix
The size in region calculates raw font and amplifies required conversion vector to target font, and concrete calculating process is as follows：
It is assumed that the original raster font prestoring is for 16 × 16 raster fonts taking x-axis conversion vector as a example, target dot matrix
Font is 20 × 20 raster fonts, calculates conversion vector (the i.e. original dot matrix of original raster font each point with reference to following algorithm
Font each point is to the required conversion vector of target raster font conversion)：
Δ x=(Xt-Xs)//XtThe x coordinate of target raster font each point, XsThe x coordinate of original raster font each point, Δ x
Change in x-axis for the font stroke distributed areas；
Dt=Xt/ Δ x//different by the way of magnification ratio carries out font amplification from prior art, in the present invention
In, the horizontal partition that sets font unit length dt, insert cut-point, if it is laterally zygomorphic by cut-point, font to be divided into left and right
Dry cut zone.For example, for 20 × 20 raster font, above-mentioned segmentation unit length dt is pressed by this font by cut-point
(x-axis to) is divided into 4 regions in the horizontal.Because font is symmetrical structure amplifying, axisymmetric each side with font
The cut zone being 2 font horizontal partition unit lengths dt including length；
The vectorial calculating process of y-axis conversion of original raster font each point ibid, will not be described here.

Dot array data after the x-axis stretching of point；TIV [y] is that the y-axis of each point converts vector；Mtx[i]:Ps(x, tIV (y)), on the y axis, will
Dot array data M after x-axis conversiontxThe mobile tIV [y] of y-coordinate in the dot array data of display font each point in [i]；
Step 400：Filter the dot array data repairing the display font calculating.
Because in the calculating process of above-mentioned conversion vector, cut-point can be inserted, so as point newly-increased in dot matrix minute
Cutpoint can affect unavoidably, amplify font display, for example, overstriking or darkened amplify font certain a part.Therefore, in display
Need before amplifying font the display font dot array data calculating to be carried out filter to repair.
In this step, find out the point being labeled as " 1 " in above-mentioned conversion vector calculating process by filter vectors fIV, that is,
Newly-increased cut-point, according to the original neighbouring relations of corresponding point, filters to newly-increased point and repairs (accepting or rejecting according to former zag trajectory).Cause
It is that this newly-increased point is judged that calculating is to realize in the vectorial calculating process of conversion, show thus without increasing font amplification
Show the computation burden of process.Wherein, by former zag trajectory cut-off method be known technology, will not be described here.

In this step, in order to reduce the refreshing frequency of LCD screen, the display font that can first a line or whole screen be shown
Dot array data caches to relief area, after the caching to the dot array data of these display fonts to be done, then by the institute in relief area
Have dot matrix data output to LCD screen, display thus can be made quick and stable, it is to avoid single display font dot array data according to
