Self-adaptive image scaling method and device of mobile platform information

Abstract

The invention discloses a self-adaptive image scaling method and device of mobile platform information. The method comprises the steps that when an information editing interface is opened to add files, whether a current file can be added or not is judged according to the maximum capacity of an attachment; when the file is added, scaling processing of a corresponding compression level is conducted on all images in the attachment according to the types, the number, the size and the maximum capacity of the attachment of the added files; the surplus capacity of the attachment is detected, a user is prompted to add files continuously when the surplus capacity is available, and when the surplus capacity is insufficient, the user is prompted to delete the file. According to the self-adaptive image scaling method and device of the mobile platform information, self-adaptive compression of the corresponding compression level can be chosen according to the capacity, finite space is completely used, meanwhile, the maximum image accuracy can be maintained, and the demand of users is met.

Description

technical field [0001] The invention relates to image compression technology, in particular to an adaptive image scaling method and device for mobile platform information. Background technique [0002] Currently, the compression mechanism for adding images in information applications (such as SMS and MMS) on the operating system is very simple, resulting in very limited attachment content. Generally, there are three forms of attachment content added in MMS: audio, video and image. For audio and video, there is usually no compression in the sending process, so image compression is the main content of MMS attachment compression. However, in the existing operating systems, compression is triggered when an image is added, and audio and video files are added without any processing. It lacks customization and reversible operations, so the following problems will occur: [0003] 1. When adding attachment content, if you select the image first, in order to ensure the accuracy of t...
