iDLRRuntimeSettings

Defines a struct to configure the text recognizer runtime settings. These settings control the text recognition process.

Attributes

Attribute	Type
`maxThreadCount`	NSInteger
`characterModelName`	NSString*
`linesCount`	NSInteger
`regionPredetectionModes`	NSArray *
`referenceRegion`	`iDLRReferenceRegion`*
`textArea`	`iDLRQuadrilateral`*
`grayscaleTransformationModes`	NSArray *

maxThreadCount

Sets the number of threads the algorithm will use to recognize label.

NSInteger maxThreadCount

Value Range

[1, 4]

Default value

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

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.
