Recognize single line

If an image contains a single line of text, it can be recognized in the fastest possible mode, without automated corrections, areas detection, and other resource-consuming steps.

To extract text from such images, use RecognizeLine method of of AsposeOCR class or use setRecognizeSingleLine(true) method of recognition settings.

Performance impact

This method is about 7 times faster than normal OCR and is highly recommended for batch processing large numbers of very simple images.


This recognition method only supports images in the following formats:

  • GIF,
  • 24-bit PNG,
  • JPEG,
  • BMP,
  • WBMP.

It also does not work with skewed images and does not support recognition settings. However, you can preprocess an image before sending it to the OCR engine.
