compression

I noticed that the command line 'zip' tool and Mac OS X's 'Compress XXX' option (available via right click in finder) are giving different output files. Not only is the size of the file a few hundred bytes bigger but the content is significantly different as well. How can I find out what command the Finder is using for compression? Take a look at An AppleScript to compress a Finder selection article. try tell application "Finder" set theSelection to the selection set selectionCount to count of theSelection if selectionCount is greater than 1 then error "Please select only one Finder item

Hi I would like to know if there is any way in Java to reduce the size of an image (use any kind of compression) that was loaded as a BufferedImage and is going to be saved as an PNG. Maybe some sort of png imagewriteparam? I didnt find anything helpful so im stuck. heres a sample how the image is loaded and saved public static BufferedImage load(String imageUrl) { Image image = new ImageIcon(imageUrl).getImage(); bufferedImage = new BufferedImage(image.getWidth(null), image.getHeight(null), BufferedImage.TYPE_INT_ARGB); Graphics2D g2D = bufferedImage.createGraphics(); g2D.drawImage(image, 0,

How can I extract a ZIP file using C#? BlindingDawn DotNetZip : class library and toolset for manipulating zip files. Use VB, C# or any .NET language to easily create, extract, or update zip files... DotNetZip works on PCs with the full .NET Framework, and also runs on mobile devices that use the .NET Compact Framework. Create and read zip files in VB, C#, or any .NET language, or any scripting environment. DotNetZip supports these scenarios: a Silverlight app that dynamically creates zip files. an ASP.NET app that dynamically creates ZIP files and allows a browser to download them a Windows

I have code that should do the compression: FileStream fs = new FileStream("g:\\gj.txt", FileMode.Open); FileStream fd = new FileStream("g:\\gj.zip", FileMode.Create); GZipStream csStream = new GZipStream(fd, CompressionMode.Compress); byte[] compressedBuffer = new byte[500]; int offset = 0; int nRead; nRead = fs.Read(compressedBuffer, offset, compressedBuffer.Length); while (nRead > 0) { csStream.Write(compressedBuffer, offset, nRead); offset = offset + nRead; nRead = fs.Read(compressedBuffer, offset, compressedBuffer.Length); } fd.Close(); fs.Close(); and I think it does, but I want to

I am toying with an application that will demo some Firefox 3.6 specific functionality, most of which are listed here: http://demos.hacks.mozilla.org/openweb/ I want to drag a zip file in the browser, unzip it, and work with the unzipped contents. Are there any existing libraries that can do this? Does FireFox 3.6 in particular have something I can use? Or would I have to roll my own unzipper library? For the record: http://github.com/augustl/js-unzip There are existing libraries, here is one (as an example): http://code.google.com/p/jslibs/ 来源： https://stackoverflow.com/questions/2163857

I currently use a custom gzip encoder for my WCF service. I want to replace it with the built-in IIS 7 compression if that is possible. I can't find info online on how to that. Is there any way to enable IIS 7 compression for WCF services? Do you know if this will be supported out-of-the-box with .Net 4? Edit June 15th: I'm still looking for a way to replace our custom gzip encoder with a mainstream approach so if you know how to do that with .Net 4 and IIS 7, please answer this question. Thanks Sidebar : My attempt at doing this manually Since I can't find how to do it by simply turning a few
