PreprocessingParams Object (COM-based API)
This object specifies how an image will be preprocessed before analysis and recognition.
Properties
Name | Type | Description |
ConvertToBWFormat | Boolean |
Specifies if the image must be converted to black and white during preprocessing. The default value is FALSE. Note. If this property is set to TRUE, the speed of recognition will increase, but the quality will decrease. |
CorrectResolution | Boolean | Specifies if the image resolution must be corrected. The default value is TRUE. |
Deskew | Boolean | Specifies if the skew angle for an image must be corrected during preprocessing. This mode is recommended if you want to automatically correct skew for images you work with. The default value is TRUE. |
DiscardJobWithDocumentsWithDigitalSignature | Boolean | Specifies if jobs containing PDF files with digital signatures should be discarded. |
KeepAnnotationsInPdf | Boolean | True if comments, notes, etc. must be preserved in PDF documents. |
PdfMode | PdfModeEnum | PDF processing mode. |
RemoveGarbage | Boolean | Specifies if garbage (excess dots that are smaller than a certain size) must be removed from the image during preprocessing. The default value is TRUE. |
RemoveTexture | Boolean | Specifies if background noise must be cleared before the recognition process starts. The default value is TRUE. |
RotationType | RotationTypeEnum | Specifies what type of rotation will be performed upon the image during preprocessing. The default value is RT_Automatic, which means that rotation will be detected automatically. |
SplitDualPages | Boolean | Specifies if the dual pages must be split during preprocessing. The default value is FALSE. |
DontModifyDocumentsWithDigitalSignature | Boolean | True if PDF with digital signatures must not be modified. |
StraightenLines | Boolean | Specifies if lines must be straightened. |
