Delphi TStringList wrapper to implement on-the-fly compression
I have an application for storing many strings in a TStringList. The strings will be largely similar to one another and it occurs to me that one could compress them on the fly - i.e. store a given string in terms of a mixture of unique text fragments plus references to previously stored fragments. StringLists such as lists of fully-qua...
What is the difference between httpCompression and urlCompression?
Looking at the node in a Web.config, I see that it allows both httpCompression and urlCompression elements. What's the difference between the two? I just want to do standard gzip, which one should I use? ...
Why am I getting an ferror on my source file using zlib deflate?
EDIT // open output file for writing if ( ( outfilefd = fopen( file_name, "w+t" ) ) == NULL ) { fprintf(stderr, "Unable to create file\n"); exit(1); } Write to the file, then need to zip it. Opening a .z file and then calling def() FILE *zipFile; if ( ( zipFile = fopen( "C:\\LOGS\\test.txt.z", "w+t" ) ...
what is the maximum theoretically possible compression rate
This is a theoretical question, so expect that many details here are not computable in practice or even in theory. Let's say I have a string s that I want to compress. The result should be a self-extracting binary (can be x86 asm but can also be some other hypothetical Turing-complete low level language) which outputs s. Now, we can ea...
possible sets of output-preserving code manipulations

C# compress a byte array
I do not know much about compression algorithms. I am looking for a simple compression algorithm (or code snippet) which can reduce the size of a byte[,,] or byte[]. I cannot make use of System.IO.Compression. Also, the data has lots of repetition. I tried implementing the RLE algorithm (posted below for your inspection). However, it pr...
Need some help porting this C code to C#
I am not very good at c at all. I have tried to capture the essense of what the C code does in C# using this wikipedia article. However my version is totally different and does not achive the same compression that the C code does. Therefore, I'd like to port the following code from C to C#. However, i do not need it to read/write to file...
Parallelization and H.264 (or probably any compression codec)? Why's it so hard?
My limited (and probably wrong?) understanding of video compression is that intra-frames are completely independent. In other words, all the picture data for a intra frame (key frame) is stored in its entirety for that frame. It's the following inter frames (P and B frames in H.264, I think) that depend on the data in other frames to b...
Script/App that automatically compiles and compresses js files as you save
I'm building a web site and have multiple js files all in one directory. When I save any one of the js files I want a script to run that will compile and compress all files using the google closure compiler jar. Example from Google Closure Compiler README: java -jar compiler.jar --js=in1.js --js=in2.js ... --js_output_file=out.js Is ...
Is it possible to gzip or compress .otf (Open Type Face) files?
When using CSS3 and custom fonts, the client needs to download .oft or .ttf files. These files can be >50K. Can these files be compressed? How? Assuming Apache web server. I am looking for a compression technique or an Apache configuration. Any ideas will help because downloading +50K files should be prevented. ...
decompress deflate64
I've got a compressed string of bytes coming out of a database which I need to decompress so as to retrieve the rtf file in there. This is the requirement. I tried to use DotNetZip and it has given me a 50% success ratio. The failed 50% gave me a unsupported encryption (0x09, deflate64) error. So I think my problem is that some of the c...
