Problems solved by technology
If there are 100 characters in the signboard, it needs to be pasted 100 times, so the operation of the staff is very cumbersome when drawing, and the position of the scale value must be manually adjusted after pasting. Manual operation will greatly reduce the accuracy of the scale value positioning, so drawing such The workload of the draftsman is very heavy during signage, and the work efficiency is very low

Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0026] Such as figure 1 As shown, to draw the thick outline of the scale value of the sign, firstly draw the arc of the sign and the scale line of the sign; secondly, determine the center and radius of the path arc where the scale value of the sign is located, the deflection angle of the scale value, the text style of the scale value, and the scale value Parameters such as font height, width factor, and character spacing, and then calculate the positioning point Location (x, y) of the scale value and the rotation angle of the scale value according to the above parameters. Such as figure 2 As shown, the location point Location (x, y) of the above scale value is obtained by the following method: according to the center point of the scale value path arc, the radius and the deflection angle of each scale value, the center point A(x, y) of the sca...

The invention discloses a scale value outline overstriking drawing method of a sign plate, comprising the steps of: firstly, drawing circular arcs and scale marks, and calculating locating points and rotation angles; secondly, setting the overstriking width value of outlines as w1, traversing the obtained outline point number chunk of the scale values through a Get Glyph Outline method according to character fonts, locating points and character font height parameters, and judging the type of the outline point number chunk; thirdly, traversing fold line arrays, and drawing a segment object of two points to be written in a public Object Id Collection class; fourthly, traversing curve arrays, and drawing a spline object to be written in the same public Object Id Collection class; and finally, carrying out polygon filling operation according to the Object Id Collection class after all of the outlines are drawn. The invention solves the technical problem of outline overstriking of character fonts of scale values and increases the work efficiency.
Description
technical field [0001] The invention relates to a graph drawing method, in particular to a method for drawing a scale value outline of a signboard in bold, and belongs to the technical field of printing. Background technique [0002] With the popularity of computers in factories, more and more companies use CAD software for drawing. In the sign making process of sign factories, CAD drawing software is generally used to draw and save the sign graphics that need to be produced in the computer. Then convert the sign graphic file into a file format compatible with the laser imagesetter and output it to the imagesetter, and the imagesetter prints out the film for production. The existing drawing software of the sign factory is based on the AutoCAD drawing software, and some improvements have been made to the sign drawing method. The sign is drawn by inputting the parameters of the sign arc, scale line, and scale value, which improves the work efficiency. When making a signage, i...
