JEG Extract Dimensions

Given a string containing a dimensioned number, sets two globals in the current data folder: V_dimensionValue is the numerical value and S_dimensionString is (dur) the dimension string. SI prefixes are extracted from the dimension string and the value is adjusted accordingly (not all prefixes are included, but they're easy to add).

Example:

JEG_ExtractDimensions("43.234 nm")

Result:

V_dimensionValue = 4.3234E-08
S_dimensionString = "m"

Needs:

• #include "JEG Strip Whitespace"

JEG Keyword-Value

Just like WaveMetrics' Keyword-Value routines, except two additional parameters are passed: a field separator and a record separator.

Example:

NanoScope^® headers consist of keyworded records. In NanoScope^® II, keywords are separated from values by " = ", but NanoScope^® III uses ":". In both, records are separated by knuckle-dragger carriage-return/line-feeds.

In my reader for NSII files, the scan size in nm is obtained by

JEG_NumByKey("scan_sz", theHeader, " = ", crlf)

In my reader for NSIII files, the scan size is obtained by

JEG_AbortingStrByKey("\Scan size", theHeaders[imageNumber], ":", crlf) and the string is converted to proper dimensions with JEG_ExtractDimensions()
