I need to compress video image data (lets say a display object) in AS3 to a Byte Array with high compression at runtime. Framerate only needs to be around 5 but 1024x768 video needs to go to < 40 Kilobyte per Second without the quality beeing tooo bad. I wrote a custom encoder and got it to around 80-100 Kilobyte per Second for 1024*768 ...

Say I had 1 MB of compressed Javascript, all combined into one file using Google Closure. Now 500 KB of it is only needed for one section of the site.

I would like to compress the data coming out of WCF on a basicHttpBinding. I am trying to produce a new version of a system originally written as SOAP web services. In that we returned a GZipStream when we received a request. Is there any way to do the same with WCF? I am using VS2010, currently against .Net 3.5 but that's flexible. ...
We have to compress a ton o' (monochrome) image data and move it quickly. If one were to just use the parallelizeable stages of jpeg compression (DCT and run length encoding of the quantized results) and run it on a GPU so each block is compressed in parallel I am hoping that would be very fast and still yeild a very significant compress...
Hello, I know that JPG and MP3 always apply some kind of compression which losses data. Then I have to questions: - Which are the lossless file formats for image, audio and video? - Why, as far as I know, any photocamera does not offer the possibility to store images in a lossless file format? - I know that the data lost is really small...

I'm looking for a good way to create a moving map app on an semi-embedded device, comparable to a netbook. The source images are 400MB tiff files with associated world and projection files. The current approach I've taken is to create a tiled dataset for the desired zoomlevels in OSM map format. It works, but uses up way too much disks...

We're currently creating a device for a customer that will get a block of data (like, say, 5-10KB) from a PC application. This is a bit simplified, so assume that the data must be passed and uncompressed a lot, not just once a year. The communication channel is really, really slow, so we'd like to compress the data beforehand, pass to th...
Hi so I have a css file, style.css. in the same directory I have the images/ folder. How can I make a script that compresses style.css, but from another folder?

Some student asked this on another site, but got no answers. I had a few stabs at it, but found it pretty tricky. Doing it with just the switches would require a 9:1 compression ratio, so I guess the trick is very much in the rules you assign to students. Perhaps every student needs a different set of rules? I've thought about allowin...
Two questions: I need to make a server that handles potentially thousands of simultaneous requests for: Hashing of files Compression of files Decompression of files Possibly some file copy / moves as well I can't control a customer's hardware (RAID configurations, etc) so I assume all I can do is request hundreds of file operations,...
I have a question regarding the use of Tomcat 6.0.14, and the interaction between the Tomcat built in compression, and custom filters. I am just using Tomcat - with no http server in front. My problem is that when I enable my filter, the compression seems to be disabled. This is observed by examining the output from a Fiddler trace. An...
I have found utilities that can compress html, javascript, and css files individually. However, lets say I have a file called homepage.php with php at the top of the page, css and javascript in the header, html in the body along with more php code and perhaps some more javascript. Sometimes, the chunks with javascript may also have php i...
