DataFlex Requires Chilkat v11.7.0+

Exclude Rotated Margin Text from PDF Extraction

See more PDF Text Extraction Examples

Demonstrates the "rotatedText" filter. Text that is not aligned with the page, such as a vertical "CONFIDENTIAL" label in the margin, is included by default (after the upright text) and flagged in the quality report; "exclude" leaves it out. DataFlex
