org.das2.graph.DasDevicePosition

DasRows and DasColumns are both DasDevidePositions that lay out the canvas. Any object on the DasCanvas have a row and column object to indicate the position of the object.

formatFormatStr

formatFormatStr( double[] arr ) → String

formats the three position specifiers efficiently.

Parameters

arr - three-element array [ npos, emoffset, pt_offset ].

Returns:

String like "100%-5em+4pt"

See Also:

parseFormatStr(java.lang.String)
formatLayoutStr(org.das2.graph.DasDevicePosition, boolean) which contains repeated code.

formats the row or column position into a string like

Parameters

pos - the row or column
min - true if the minimum boundary is to be formatted, false if the maximum boundary is to be formatted.

Returns:

String like "100%-5em+4pt"

parseFormatStr

Deprecated: use parseLayoutStr.

parseLayoutStr

parseLayoutStr( String s, double em, int widthHeight, double fail ) → double

parse the format string into a pixel count. Convenience method. parseFormatStr(s) will throw a parse exception and should be used to verify strings.

Parameters

s - The string, like "5em+3pt"
em - the em height of the font,
widthHeight - the width or height of the dimension.
fail - the value to return if the parsing fails.

Returns:

the length in pixels (or points).
