Conversion is all contained in protection scope of the present invention.
Refering to a kind of preparation method of mirror image bar code shown in Fig. 1 to Fig. 4, comprise the following steps：
S100：Extraction source bar code symbol, the source bar code symbol are carried on bar code image, position the source bar code symbol
Position on bar code image；
Specifically, the bar code image of the extraction can extract bar code or two-dimensional strip from existing barcode database
The picture of code, wherein bar code can include Code39, Code93, Code128, Codabar, EAN-13, EAN-8, UPC-
A, ISBN-13, GS1-128, ITF-14 etc., two-dimensional bar code can include PDF417, QR, Data Matrix, Grid Matrix
With Chinese letter co etc..
Due to the source bar code symbol comparison rule in database and irrelevant information has been eliminated, simple method can be used
Positioned：On the bar code image, full figure is scanned, judges each black pixel point occurred on bar code image, its vertical seat
It is lower boundary when marking minimum, is coboundary when maximum, is left margin during abscissa minimum, is right margin when maximum.So mark
Source bar code symbol lower-left angle point (bcleft, bcbottom), bottom right angle point (bcright, bcbottom), upper left angle point
(bcleft, bctop), upper right angle point (bcright, bctop).
Coordinate according to each point of source bar code symbol calculates the wide and high of source bar code symbol.Coordinate value meter according to each point
Calculation source bar code symbol it is a height of：Bh=bctop-bcbottom, source bar code symbol it is a width of：Bw=bcright-bcleft.
S200：Inputted mirror transformation parameter is received, the mirror transformation parameter includes mirror transformation direction, according to mirror
As generation mirror transformation matrix of changing direction；
Described mirror transformation direction can be set according to demand, such as can carry out vertical mirror conversion, horizontal mirror transformation
Or 45 ° of direction mirror transformations etc..
According to set mirror transformation direction, the generation mirror transformation matrix corresponding with the mirror transformation direction.
Such as the matrix of vertical mirror conversion isThe matrix of horizontal mirror transformation is
S300：The coordinate of all pixels point of source bar code symbol is subjected to mirror transformation by mirror transformation matrix respectively,
Obtain mirror image bar code symbol；Obtained in the template and translatory mirror slice code sign to the template of the carrying mirror image bar code symbol of generation one
Obtain mirror image figure；
Specifically, the coordinate of all pixels point of source bar code symbol is passed through to the mirror transformation of mirror transformation matrix respectively,
The coordinate position of each pixel of change source bar code symbol, it is allowed to complete mirror transformation acquisition mirror image bar code symbol.
In internal memory generate background for white bmp images as carrying mirror image bar code symbol template, be somebody's turn to do during with
The coordinate points in the most upper right corner of the source bar code symbol inputted are width, the height of template, that is, the template width generated is in this implementation
It is set as W=bcright in mode, is highly H=bctop, so that the template carries newly-generated mirror image bar enough
Code sign.In this embodiment, the template background generated can also be other colors, can set mould according to the demand used
The background of plate.
S400：Preserve simultaneously outgoing mirror picture figure.The mirror image figure that is generated is exportable to be stored in Installed System Memory, or passes through printing
Equipment prints out.

Quadrant just can be such that mirror image bar code symbol is normally shown in template, specifically, the i.e. relative Y-axis of horizontal mirror transformation is symmetrical, warp
Cross negative direction of each pixel of image after matrixing along Y-axis and move the distance of a template width, therefore born in Y-axis
The coordinate of each point will add template width on direction.Therefore along X-direction translatory mirror slice code sign, translation size is mould
Plate width W, therefore the coordinate position of each pixel of final mirror image bar code symbol is：(- x+W, y).
The mirror transformation direction can also be that vertical mirror converts, and the vertical mirror shift step is as follows：By column from
Under supreme scanning source bar code symbol, all pixels point coordinates of source bar code symbol is passed through into transformation matrix respectivelyMirror
As conversion, mirror image bar code symbol is obtained；Along Y direction translatory mirror slice code sign to template.
Specifically, scanning source bar code symbol from left to right by column, passed through for pixel point coordinates in the bar code symbol of source for (x, y)
It is (x ,-y) to cross corresponding pixel point coordinates after transformation matrix, but the image after mirror image should be moved to from fourth quadrant first as
Limit just can be such that mirror image bar code symbol is normally shown in template, therefore along Y direction translatory mirror slice code sign, translate chi
Very little is form height H, therefore the coordinate position of each pixel of final mirror image bar code symbol is (x ,-y+H).
The preparation method of described mirror image bar code, also include source bar code before the position coordinates of locating source bar code symbol
Symbol carries out binary conversion treatment.
Specifically, its step is scanning source bar code symbol full figure, gray scale formula gray=0.2126*r+0.7152*g is utilized
+ 0.0722*b calculates the gray value of each pixel, and compared with given threshold 128, gray ＞ 128 pixel switchs to white
Color (is entered as 255), and the pixel of gray ＜=128 switchs to black (being entered as 0).
