This function was introduced in Quick PDF Library version 8.12.
Sets the area for certain modes of text extraction. Any text that appears outside this area will be excluded from the results. This function has no effect on text extraction using modes 0 to 2.
From 8.13, this function sets the text extraction area for the selected document only. It also only affects the results of the GetPageText function.
The area limitation can be removed by calling this function with a value of zero for both the Width and Height parameters.
