Printing processing method and device

Abstract

The invention provides a printing processing method and device. The method comprises the following steps: determining the concavity and convexity of a starting point of a curve to be processed and theconcavity and convexity of an end point of the curve; if the starting point is concave, adding a newly added break point at the first position of the curve; wherein the first position is a position,which is a preset distance away from the starting point, on the curve; if the terminal point is concave, adding a newly-added break point to a second position of the curve, the second position being aposition, away from the terminal point by a preset distance, on the curve to obtain a processed curve, and determining the preset distance based on the minimum precision of the data type; folding theprocessed curve to obtain a fold line formed by a plurality of fold line segments; generating dot matrix data according to the broken lines, and printing the dot matrix data. According to the scheme,the sharp corner problem existing in the prior art can be solved, so that the accuracy of the generated dot matrix data is improved, and the accuracy of a printing result is further improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a printing processing method and device. Background technique [0002] Raster Image Processor (RIP for short) is an interpreter, which is used to convert the layout information described by the page description language into dot matrix data, so that the device can print the dot matrix data to obtain the required print files, etc. Among them, the drawing of the curve is one of the main tasks of RIP. The curve is converted into a broken line to obtain a broken line, and then the broken line is filled to obtain dot matrix data, and then the device prints the dot matrix data. [0003] In the prior art, under normal circumstances, the two endpoints of a curve are often connected with the endpoints of other curves, or the endpoints of a straight line segment. In this way, after each curve is polylined and each polyline is obtained, each polyline or When filling a str...

Problems solved by technology

[0004] However, in the prior art, when the curve is broken into lines, there is a problem of the accuracy of the broken lines, which may lead to deviations in the angles of the determined connection points, which will cause the shapes of some connection points to be modified but not corrected. In the case of modification, there is still the problem of sharp corners, resulting in the generated dot matrix data is still inaccurate, and then when printing according to the dot matrix data, the printing result will still be inaccurate
