AI Technical Summary

Technical Problem

The image of an electronic seal is prone to jagged edges and blurring when magnified and previewed, and the printed seal is not the same size as the physical seal, which affects the mutual trust and recognition of electronic documents and the efficiency of application.

Method used

By acquiring the pixel information of the electronic seal image, a lossless magnification algorithm is used to enlarge it to the target pixel size. Combined with the seal position and size information of the layout document, a transformation matrix is ​​used to scale the enlarged image to the specified position, ensuring that it is displayed at a size smaller than the lossless magnification when the document is enlarged for preview.

Benefits of technology

It effectively eliminates jagged edges and blurriness caused by magnification, improves the clarity and printing consistency of electronic seals, enhances the application efficiency of electronic documents, and avoids repetitive operations.

Abstract

The embodiment of the invention provides an electronic seal processing method and device, electronic equipment and a storage medium. The method comprises the steps that a first electronic seal image is acquired; determining a second electronic seal image according to the pixel information of the first electronic seal image and the target pixel information; converting the second electronic seal image to obtain a third electronic seal image in the format document; according to the stamp position information and the size information in the format document, the third electronic stamp image in the format document is converted and placed at the position corresponding to the stamp position information and the size information, and the converted target electronic stamp image is obtained. And the electronic seal is still displayed in a size smaller than that after lossless amplification, so that the image of the electronic seal is kept clear, and sawtooth and blurring conditions caused by amplification are eliminated to a greater extent.
