基于移动设备的PNG图片优化实现

随着硬件技术的发展,移动设备的性能获得很大的提高。在移动设备上我们已经可以使用各种图像、音乐资源。目前在图片的使用上局限在几种格式,PNG自身的一些优点使其在移动设备上获得广泛的应用。移动设备应用程序的开发需要用到大量的图片资源,而这些对于程序员来讲是比较难于管理的。为图片资源开发一个可以方便读取的包文件结构,对图片进行打包,并提供相关方法接口,可以节约程序员的编码时间,同时可以方便对图片的读取管理。由于PNG图片的数据结构中部分数据块是可选的,这些数据块并不影响图片在移动设备上的表现效果,对PNG进行适当的处理可以有效的减少占用空间,优化移动设备上的图片应用。

Based on Mobile Devices Optimized to Achieve the PNG Image

With the development of hardware technology,the performance of mobile devices have greatly improved,on mobile devices we can use some kinds of images and music resources.At present,we can only use several formats.PNG is used widely by its benefits.Mobile device application development requires a great deal of resources picture,which is more difficult to manage in terms of for the programmer.Developing a package structure for the image resources which can be read easily,packaging the images,and provide interfaces,it will help the programmers to save their time,and they can manage the read of images easily .For more,some data chunks of PNG is unnecessary,so we can delete them to save storage space,it is helpful for the use of images on mobile devices.
