Function Reference


_GDIPlus_StringFormatSetMeasurableCharacterRanges

Sets a series of character ranges for a StringFormat object that, when in a string, can be measured

#include <GDIPlus.au3>
_GDIPlus_StringFormatSetMeasurableCharacterRanges ( $hStringFormat, $aRanges )

Parameters

$hStringFormat Pointer to a StringFormat object
$aRanges Array of character ranges:
    [0][0] - Number of character ranges
    [1][0] - Character range 1 specifying the first position of range 1
    [1][1] - Character range 1 specifying the number of positions in range 1
    [2][0] - Character range 2 specifying the first position of range 2
    [2][1] - Character range 2 specifying the number of positions in range 2
    [n][0] - Character range n specifying the first position of range n
    [n][1] - Character range n specifying the number of positions in range n

Return Value

Success: True.
Failure: False and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPID_ERR*).
