How-To: Image Processing

Overview

Numerous image processing functions offered by ClearImage help to:

  • Improve the quality and reduce the size of compressed image files
  • Prepare image for better visual representation on the Web or in an application.
  • Improve OCR/ICR reading rate
  • Enable the reading of severely flawed or poor quality barcodes by ClearImage barcode readers

The following examples demonstrate the use of the most popular image processing function. These are merely examples for demonstrating the use of the functions, and do not represent actual production examples. In a production application the specific sequence of functions should be selected based on specific application needs. The ClearImage Demo application offers scripting specifically to support the experimentation and selection process with real life images:

  • Use the Repair menu to try particular functions and parameters
  • Use the Script menu to build a sequence of functions for easy testing with multiple image files
  • Use the File menu -> "Open Sample Script and Image …" to see how some of the most popular functions work
