localizationSourceType

The source type used to localize the reference region(s).

NSInteger localizationSourceType

Value Range

A value of EnumDLRLocalizationSourceType Enumeration items.

Default value

EnumDLRLocalizationSourceTypeManualSpecification

Remarks

points

Four vertexes in a clockwise direction of a quadrilateral. Index 0 represents the left-most vertex.

Remarks

It works only when localizationSourceType is setting to EnumDLRLocalizationSourceTypeManualSpecification.
The library will localize reference region(s) based on the quadrilateral set by current setting.

regionMeasuredByPercentage

Whether or not to use percentage to measure the coordinate.

NSInteger regionMeasuredByPercentage

Value Range

[0, 1]

Default value

1

Remarks

When it’s set to 1, the values of points indicate percentage (from 0 to 100); Otherwise, they indicate coordinates in pixel.
0: not by percentage
1: by percentage
It works only when localizationSourceType is setting to EnumDLRLocalizationSourceTypeManualSpecification.

regionPredetectionModesIndex

The index of a specific region predetection mode in the regionPredetectionModes parameter.

NSInteger regionPredetectionModesIndex
