Returns True or False to indicate if images are converted to grayscale before they are read using OCR. Use when debugging OCR statements to see if grayscale conversion is used and determine if changes are needed to improve the accuracy of returned text. Grayscale conversion is set in the playback options or by the OCRConvertToGrayscale statement. See Troubleshooting OCR issues.
Syntax
OCRIsConvertingToGrayscale()
Return value
| Value | Description |
|---|---|
| True | Images are converted to grayscale. |
| False | Images are not converted to grayscale. |
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
