A handwritten signature method suitable for ios application

Abstract

The present invention relates to a handwritten signature method suitable for iOS applications. Touch points are recorded in the signature area. After 3 effective touch points are recorded, several Bezier curves are constructed and optimized for each 3 touch points. The obtained Calculate the speed of the points on each Bezier curve, calculate the rendering points above and below the corresponding handwriting, render the current point based on the rendering points, and get the handwritten signature after traversing all the Bezier curves. The handwriting effect generated by the present invention is more smooth and natural, and the writing effect is more in line with the effect of writing and sketching in reality. It brings a better handwriting experience on iOS devices and is conducive to handwriting identification, and is more suitable for the current paperless office. In the general environment, the legal effect of documents is guaranteed, and the effectiveness of documents is improved, which means that office efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electronic digital data processing, in particular to a handwritten signature method suitable for iOS applications. Background technique [0002] With the enhancement of people's awareness of environmental protection, the continuous upgrading of the demand for office models in various industries, and the acceleration of modernization and information construction, paperless office has gradually been applied to many industries from the concept. With the popularization of paperless office, people first realized the advantages of this office model in various business halls and in the process of handling various businesses, effectively improving the operator's internal business document management and external customer service quality and overall efficiency. The implementation of paperless office has greatly reduced paper documents, and the office expenses such as printing and paper use have also been reduced ...

Problems solved by technology

[0004] In the prior art, taking iOS as an example, the simple implementation of handwritten signatures is to obtain touch points in sequence and connect them with straight lines. When the touch points captured by the iOS device are dense enough, the signature looks smoother, but when When the writing speed is accelerated and the captured touch points are relatively scattered, the touch points will be directly connected by straight lines, and the corners between the straight lines can be clearly felt by the naked eye, such as figure 2 As shown, the connection between points is too blunt, and the generated signature effect is generally blunt, and handwriting cannot be analyzed well, which creates uncertain factors for the legal effect of the document.
