#Two types of image compression code
Hi, thx for such a nice article, i have implemented the code in my vb.net application and able to generate. How i can write the file compression/decompression code in Visual C++ 2005 You are not assigning the values selected in the OpenFileDialog and FolderBrowserDialog to the text windows so when you select a file nothing shows up in the text box and same with the folder.įile compression/decompression in VC++ 2005 I tried it but it can not compress a large file such as database with a size of 1 Gigabyte or more than. How ca I compress database with a size of 1 gigabyte or more than. this is very usefuĮxcellent post and informative. I have need for demo file and source codeĪmazing, thanks a lot. Singh, you have this kind of helping-hand and mind tutorial. MPEG-2 codec, psychoacoustics etc.).Īmong these I am going to describe the DEFLATE and GZIPĬompression and its implementation in VB 2005. Run-length encoding, Lempel-Ziv (LZ), Huffman, Deflate, GZip, TTA, FLAC, etc.)Īnd lossy encoding schemes (e.g. Now, there are various lossless encoding schemes (e.g. Graphical image can be compressed either as lossless or lossy method Lossy compression algorithm because among these some loss of data can be Picture, audio or video format data are usually compressed with This compression works on those data in which some fidelity isĪcceptable. You do not get exact original data back in lossyĬompression. In lossy compression, the algorithm does some loss of data The major purpose, as well as challenge, for losslessĪlgorithms is to compress data as much as possible and get back the original Lossless compression should be used to compressĮxecutable programs. In business communication we use lossless compression for textīased data/information.

It means exact source data should be generated afterĭecompression. In lossless compression, the algorithm does not lose any In general we divide compression algorithms in two types: Print Add To Favorites Email To Friend Rate This ArticleĬompression and Decompression of Files using Visual Basic 2005 ASP.NET Tutorials » Compression and Decompression of Files using Visua.
