Number indicating the right limit to which the search is performed. This is expressed in
characters for a text file, or in millimetres for a PDF file.
Examples
To look for the word "text" on an entire Letter page (8 1/2 x 11 inch), the syntax is:
data.find("text", 0, 216);
The numbers 0 and 216 are in millimeters and indicate the left and right limits (constraints)
within which the search should be performed. In this example, these values represent the entire
width of a page. Note that the smaller the area is, the faster the search is. So if you know that
the word "text" is within 3 inches from the left edge of the page, provide the following:
data.find("text", 0, 76.2); //76.2mm = 3*25.4 mm
The return value of the function is:
Left=26,76, Top=149.77, Right=40,700001, Bottom=154.840302
These values represent the size of the rectangle that encloses the string in full, in millimeters
relative to the upper left corner of the current page.
findRegExp()
Finds the first occurrence of a string that matches the given regular expression pattern, starting
from the current position.
findRegExp(regexpToFind, flags, leftConstraint, rightConstraint): rectValueText)
Finds the first match for a given regular expression pattern starting from the current position.
Regular expression flags (i,s,L,m,u,U,d) are specified in the flags parameter. The search can
be constrained to a vertical column of characters located between the left and right constraint,
each expressed in characters (in a text file) or millimeters (in a PDF file).
Partial matches are not allowed. The entire match for the regular expression pattern must be
found between the two constraints.
The method returns null if the regular expression produces no match. Otherwise it returns a
RectValueText object, containing the Left, Top, Right and Bottom coordinates - expressed in
characters (in a text file) or millimeters (in a PDF file), relative to the upper left corner of the
