specifically, the handwriting reduction step of the embodiment includes the following steps:
handwriting restoration means that the position of a pen written on the code dot paper, namely first position information (X1Y1 code dot coordinates), is accurately corresponding to the position of an APP side drawing area, namely second position information (X2Y2 pixel coordinates) through coordinate conversion.
One point to be considered first is that the ratio of width to height of code point paper (W1/H1) must be equal to the ratio of width to height of APP end drawing area (W2/H2), i.e. W1/H1 ═ W2/H2
The width and height of the code dot paper calculated in this embodiment are specifically as follows: the code point paper is generated by generating a PDF document with code points through a code spreading tool, and in the process, the code spreading tool can derive a background image file (PNG) of 300dpi from the PDF text. However, knowing how many dpi (a dpi represents the number of pixels in an image per inch of length) an image file can generally be divided by the size of the PDF document (usually in inches) to obtain the value of dpi.
The process of calculating W1 and H1 in this embodiment specifically includes: since W1 and H1 are both code point coordinate units, they can be converted from the pixel coordinates of the background image file (PNG) width (Wb) height (Hb), so W1 is Wb/300 × 25.4/1.524, where Wb/300 is the pixel unit converted into inch unit, converted into millimeter (mm) unit, multiplied by 25.4, converted into code point coordinate unit, divided by 1.524(1 unit code point coordinate is 1.524mm), and similarly, H1 is Hb/300 × 25.4/1.524;
in this embodiment, W2 is 700, and H2, H2 is W2 × H1/W1 are calculated.
The specific steps of converting the code point coordinates of X1Y1 into the pixel coordinates of the position X2Y2 of the APP-side drawing area in this embodiment are as follows:
according to coordinate conversion and correspondence, X2 is X1W 2/W1; y2 ═ Y1 × H2/H1; since the pixel coordinates of X2, Y2, W2 and H2 are all integer values, (since the coordinates of code points of W1 and H1 are real values, preferably, the embodiment declares X2, Y2, W2 and H2 to be real values), finally obtaining X2 and Y2, and rounding X2 and Y2 to obtain the final conversion result.
B2, packaging the coordinate point information converted in the step B1 into an object which realizes a serialization interface by the system, wherein the object realizes the conversion of object attributes and file attributes;
b3, setting corresponding modes for each coordinate point according to different writing scenes, wherein the modes mainly comprise a writing mode and an eraser mode. The writing mode is used for writing, a user can set the thickness and the color of a pen in the writing mode, and the written handwriting is the color set by the user;
the eraser mode is that a user can erase an error place after selecting the eraser so as to achieve the purpose of correction, and the user can erase written objects by wiping the place needing to be corrected on a screen with fingers. The writing mode is selected in a scene that the user needs to write, and the eraser mode is selected in a scene that the user wrongly writes or needs to modify the writing situation.
C. And (4) storing data.
The electronic system of this embodiment determines whether the output file exists, if not, a serialized file is created, and if so, the file output interface is directly opened, and the object converted in step B is written into the file.
Specifically, the handwriting recognition process of the embodiment includes the following steps:
A. reading data;
specifically, the step a is to acquire page number data displayed on the current screen, read a system coordinate point file according to the page number data, convert the serialized data into coordinate point data again, and store the data in the memory, so as to facilitate the next data processing.
B. Processing data;
and step B, specifically, acquiring the coordinate point data obtained in the step A, analyzing the coordinate point data into one stroke-falling, writing and pen-lifting operation process, wherein one stroke is written every time, and then converting the coordinate point data of each stroke into unified abscissa and ordinate data again to form an array-form data structure.
This is a coordinate point data for drawing a written document in one stroke, taking as an example the following data, in which the data of ntype ═ 0 is the data generated at one instant of pen-down, the data of ntype ═ 1 is the coordinate point data generated by writing, and the data of ntype ═ 2 is the data finished when pen-up is performed, wherein the pointX and pointY data are extracted and reconstructed as [, ]
