Picture superposition method and system

Abstract

The invention is applicable to the technical field of picture processing and discloses a picture superposition method and a system. The method includes that by means of a map based application program interface, a first picture is loaded to be used as a base picture, each point on the base picture corresponds to a geographical coordinate, and a second picture is added to the position of a geographical coordinate corresponding to a base picture required to be placed in a labeling form; the picture superposition system comprises a first picture loading module and a second picture adding module, the first picture loading module is used for loading the first picture to be used as the base picture through the map based application program interface, and each point on the base picture corresponds to a geographical coordinate; and the second picture adding module is used for adding the second picture to the position of the geographical coordinate corresponding to the base picture required to be placed in a labeling form. By means of the picture superposition method and the system, the geographical coordinate is bound during picture superposition so that original positions can not be deviated under the condition that monitor resolution is changed.

Description

technical field [0001] The invention belongs to the technical field of picture processing, and more particularly relates to a method and system for superimposing pictures. Background technique [0002] In the field of image processing technology, especially in the production of web pages, it is often encountered that images need to be superimposed to meet the different needs of different industries. For example, it is necessary to superimpose a picture B on another picture A, with picture A as the background, and the position of picture B in picture A is fixed, and when the screen resolution is changed, the picture B (can be multiple pictures) The position is still in the original position of picture A. A very common application of this scenario is to load some icons on the electronic map, and these icons may be text or special marks. [0003] Aiming at the above technical problems, the general method adopted in the prior art is: use javascript browser scripting language t...

AI Technical Summary

Problems solved by technology

[0004] 1. The base map A cannot be moved, zoomed in, zoomed out. Viewing superimposed pictures or maps must rely on the scroll bar of the browser, which is inconvenient to operate

[0005] 2. Since the software cannot always run on only one machine, recording the pixel coordinates of the picture will definitely cause problems due to different display resolutions, making picture B deviate from its original position
