ImageEn,图像处理工具。看看它的介绍吧： Input/output: Support for asynchronous load/save operations ?Load and save JPEG (RGB, GrayScale, YCbCr, CMYK, YCbCrK) to file or stream (with also 1/2, 1/4 and 1/8 subsizes for fast preview). Read/write APP0-APP15,COM Jpeg markers. ?JPEG2000: JP2, J2K and JPC code stream formats (JPEG-2000 Part-1 standard, ISO/IEC 15444-1) ?Jpeg Lossless transformations and cut ?Estimation of Jpeg file quality ?Optional Color Management System (CMS) to process ICC profiles-ImageEn, image processing tools. Its introductory look at it : Input / output : Support for asynchronous load / save operations Load and save JPEG (RGB, GrayScale, YCbCr, CMYK, YCbCrK) to file or stream (also with 1 / 2, 1 / 4 and 1 / 8 for subsizes fast preview).

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. 下载
