Usage:
Required Parameters:
-
n1= number of samples in the 1st dimension
-
n2= number of samples in the 2nd dimenstion
-
Optional Parameters:
-
error=0.01 relative RMS allowed in compress
-
Notes:
- This program is used to compress a 2D section. It compresses in both
- directions, vertically and horizontally.
- The parameter error is used control the allowable compression error,
- and thus the compression ratio. The larger the error, the more
- the more compression you can get. The amount of error depends on
- the type of data and the application of the compression. From my
- experience, error=0.01 is a safe choice even when the compressed data
- are used for further processing. For some other applications, it
- may be set higher to achieve larger compression.
Caveats:
- For the current implementation, the compressed data themselves are
- NOT portable, i.e., the data compressed on one platform might not be
- recognizable on another.
