Sets the scale of an image before reading it using OCR. Use to override the default OCR scale set in the playback options, which may help improve the accuracy of returned text. See Troubleshooting OCR issues.
Syntax
OCRSetScale(Scale)
Arguments
| Argument | Description |
|---|---|
| Scale | Number of times larger than the original image size to increase the scale. Enter a value between 1 and 15. For example, 1 scales to original size (100%), 2 scales two times the original size (200%), and 15 scales 15 times the original size (1500%). |
Example
'Saves default OCR settings
lang = OCRGetLanguageFilePath()
contrast = OCRGetContrast()
imgScale = OCRGetScale()
grayConversion = OCRIsConvertingToGrayscale()
Try
'Changes OCR settings for the checkpoint
OCRSetLanguageFilePath("C:\\tessdata\\MICR.traineddata")
OCRSetContrast(50)
OCRSetScale(2)
OCRConvertToGrayscale(True)
'Verifies text in the page footer
Window("ACME Bank").OCRCheckpoint(92, "ACME Bancorp, Member FDIC", 13, 4, 86, 11, False, "Footer text is incorrect")
Finally
'Resets default OCR settings
OCRSetLanguageFilePath(lang)
OCRSetContrast(contrast)
OCRSetScale(imgScale)
OCRConvertToGrayscale(grayConversion)
End Try
