PR Summary

• Elimination of Unnecessary PDF Tags
  Removed a condition in the code that uselessly added text tags into the PDF file in certain circumstances. Now, the system won't call the function writeText() when this condition is not fulfilled, optimizing the performance and speed of PDF file generation.
