Abstract

The invention discloses a method and device for optimization processing of PNG (portable network graphic) image resources. The method comprises the following steps: respectively extracting palette data of each PNG image and image data of any one PNG image from N PNG image files with the same pattern; and combining the image data and the palette data of the N PNG images to generate a new PNG image group file. By calling the PNG image group file during the development process of J2ME (Java 2 micro edition) terminal applications, the invention can reduce the data redundancy of the PNG image files in this group, thereby reducing the volume of application package and saving storage resources.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for optimizing PNG image resources in a J2ME terminal. Background technique [0002] J2ME (Java 2 Micro Edition) is a highly optimized Java operating environment, mainly for consumer electronic devices, such as cellular phones and video phones, digital set-top boxes, car navigation systems, etc. [0003] In the J2ME architecture, the goal of Connected, Limited Device Configuration (CLDC for short) is to provide a standardized, highly portable, and small memory capacity Java application development platform for devices with limited resources and network access capabilities. Supported devices include mobile terminals; Mobile Information Device Profile (MIDP for short) creates a development application environment for small, resource-constrained mobile devices. [0004] The development of J2ME mobile phone applications is based on CLDC and MIDP specifications....
