PDF Text Extraction Tolerance Factors
When extracting text from a PDF(for example, through a data selection), a lot more happens in the
background than what can be seen on the surface. Reading a PDFfile for text will generally return text
fragments, separated by a certain amount of space. Sometimes the text will be shifted up or down, spacing
will be different, etc. In some cases, every letter is considered to be a different fragment.
Text formatting features such as kerning, bold, exponential, etc, may cause these fragments to be
considered as separate even if, to the naked eye, they obviously belong together.
The PDFText Extraction Tolerance Factors is used to modify the behavior of data selections made from
PDFdata files from within PReS Workflow. Each factor available in this window will determine if two
fragments of text in the PDFshould be part of the same data selection or not.
Warning
The default values are generally correct for the greatest majority of PDF data files. Only change these
values if you understand what they are for.
Delta Width
Defines the tolerance for the distance between two text fragments, either positive (space between
fragments)or negative (kerning text where letters overlap). When this value is at 0, the two fragments will
need to be exactly one beside the other with no space or overlap between them.
When this value is at 1, a very large space or overlap will be accepted. This may case "false positives" and
separate words and text blocks may be considered as a single word if the value is too high.
