提示： JPEG压缩分为三个部分： 1.JPEG压缩原理及算法（RGB/YCbCr,DCT/IDCT,量化,Z字型编码,用DPCM对DC/用RLE对AC编码/Huffman编码） 2.JPEG标记格式 3.JPEG图片文件的组织形式（位于SOS后的图像压缩数据是由MCU块怎样排列的，特别是使用了DRI之后） 还有许多细节问题： 1.解码过程中遇到“FF 00”当“FF”处理，否则忽略“FF” 2.进行DCT前YCbCr要减128，进行IDCT前要加128（相当于Y减128，YCbCr不需要加128） 3.每个标记中数据可以不止一个（去掉长度的部分就是一段）-Tip : JPEG compression is divided into three parts : Principles and 1.JPEG compression algorithm (RGB/YCbCr, DCT/IDCT, quantification, Z-shaped coding, using the DPCM DC/AC with RLE encoding/Huffman coding) 2.JPEG tags 3.JPEG Photo paper form (located in the SOS image data is compressed by the MCU to set pieces, particularly after the use of DRI), there are many details : 1. decoding process encountered "FF 00," when the "FF", otherwise overlooked "FF" 2 .DCTYCbCr128IDCT128Y128YCbCr128 3.

介绍了取景变化和模型变化,进行平移和旋转,取景变化相当于相机的变换,模型变化用来控制图形元素的位置-introduced the viewfinder change and model changes, translation and rotation of the camera viewfinder or changes transform the model used to control changes in the location of graphics elements
