maxThreadCount
Sets the number of threads the algorithm will use to recognize label.
NSInteger maxThreadCount
Value Range
[1, 4]
Default value
4
Remarks
To keep a balance between speed and quality, the library concurrently runs four different threads by default.
characterModelName
The name of the CharacterModel.
NSString* characterModelName
linesCount
Sets the text lines count of the text area.
NSInteger linesCount
Value Range
[0, 200]
Default value
0
Remarks
0: line count is not certain.
regionPredetectionModes
Sets the region pre-detection mode.
NSArray * regionPredetectionModes
Value Range
Each array item can be any one of the EnumDLRRegionPredetectionMode Enumeration items.
Default value
[EnumDLRRegionPredetectionModeSkip,EnumDLRRegionPredetectionModeSkip,EnumDLRRegionPredetectionModeSkip,EnumDLRRegionPredetectionModeSkip,EnumDLRRegionPredetectionModeSkip,EnumDLRRegionPredetectionModeSkip,EnumDLRRegionPredetectionModeSkip,EnumDLRRegionPredetectionModeSkip]
Remarks
The array index represents the priority of the item. The smaller index is, the higher priority is.
referenceRegion
Sets the reference region to search for text.
iDLRReferenceRegion* referenceRegion
textArea
Sets the text area relative to the reference region.
iDLRQuadrilateral* textArea
grayscaleTransformationModes
Sets the grayscale transformation mode.
NSArray * grayscaleTransformationModes
Value Range
Each array item can be any one of the EnumDLRGrayscaleTransformationMode Enumeration items.
Default value
[EnumDLRGrayscaleTransformationModeOriginal,EnumDLRGrayscaleTransformationModeSkip,EnumDLRGrayscaleTransformationModeSkip,EnumDLRGrayscaleTransformationModeSkip,EnumDLRGrayscaleTransformationModeSkip,EnumDLRGrayscaleTransformationModeSkip,EnumDLRGrayscaleTransformationModeSkip,EnumDLRGrayscaleTransformationModeSkip]
Remarks
The array index represents the priority of the item. The smaller index is, the higher priority is.
Yes
No
