Problems solved by technology

[0003] The existing method of adding a watermark to a picture is to directly synthesize the watermark and the picture, and store the synthesized picture on the server, but this method cannot obtain a picture without a watermark
Another method is to decode the picture, store the decoded picture and watermark in the canvas, and generate a picture with a watermark based on the canvas information, but the data after decoding the picture is large and easily takes up a lot of memory and takes a long time to decode

Abstract

The invention provides a method for dynamically displaying a watermark image, and the method comprises the steps of obtaining a first image, and displaying the first image through a UIImage View control, wherein the first image is an image to be added with a watermark; adding a UILabel control into the UIImage View control; obtaining watermark information, displaying the watermark information through a UILabel control, and forming a second image, wherein the second image is an image added with a watermark. According to the method disclosed by the invention, the memory consumption and the time consumption during picture decoding and drawing are reduced.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for dynamically displaying watermarked images. Background technique [0002] With the rapid development of electronic technology, electronic devices such as mobile phones and tablets are widely used in people's daily study, work and life. During daily use of electronic devices, people often need to use electronic devices such as mobile phones to edit and process pictures, such as adding borders and watermarks. Among them, adding a watermark can include adding graphics, numbers, text, etc. to the original picture, which will not completely block the picture in the original picture, and can also achieve the purpose of beautifying the picture and protecting copyright. [0003] The existing method of adding a watermark to a picture is to directly synthesize the watermark and the picture, and store the synthesized picture in a server, but this method cann...
