class TextZonesUnit extends IntermediateResultUnit
Methods
| Methods | Description |
|---|---|
getTextZones |
Gets an array of TextZone objects, each representing the geometric boundaries of a detected text zone within the image. |
getCount |
Gets the number of text zones. |
getTextZone |
Gets the text zone at the specified index. |
removeAllTextZones |
Removes all text zones. |
removeTextZone |
Removes the text zone at the specified index. |
addTextZone |
Adds the specified text zone. |
setTextZone |

Inherited Methods
The following methods are inherited from class IntermediateResultUnit.
| Method | Description |
|---|---|
clone |
Creates a copy of the intermediate result unit. |
gethashId |
Gets the hash ID of the unit. The hash ID is the unique identifier for the intermediate result unit. |
getOriginalImageHashId |
Gets the hash ID of the original image. You can use this ID to get the original image via IntermediateResultManager class. |
getOriginalImageTag |
