redux¶

redux is a library for loading an image, doing some basic processing and generating a viewable image.

Goals¶

• simple to use python library
• simple to use network daemon that can answer requests for an image and the pipeline of processing to do on it
• simple to use command line client that uses either the network daemon or locally imported python library to do processing
• complex behind-the-scenes result caching

Potential uses¶

• a command line program like xv or imagemagick to view myami images and generate publication quality results
• preparing image for display in Leginon, including contrast adjustments, binning, power spectrum, etc
• any functions in leginon/appion where you need to either bin or calculate power spectrum
• preparing image for display on web pages. web server can contact redux server. this can replace php-mrc module which no longer compiles with php > 5.2

New Ideas as of 7/13/2011¶

Investigating gstreamer as a framework on which to build redux. gstreamer allows plugins called "elements" to be connected together to form a pipeline or graph that does multimedia processing. Here is an example application built using the command line program "gst-launch":

gst-launch filesrc location=example.png ! pngdec ! jpegenc ! filesink location=test.jpg
