# BarcodeDecodingSection

`BarcodeDecodingSection` defines the configuration settings for the barcode decoding process. In JSON, it is represented as a Section object with `"Section": "ST_BARCODE_DECODING"`.

## JSON Structure

**Location in template:**
```
BarcodeReaderTaskSettingOptions[i]
    └── SectionArray[j] (Section object where Section = "ST_BARCODE_DECODING")
```

**Parent object:** [SectionArray](https://www.dynamsoft.com/capture-vision/docs/core/parameters/reference/barcode-reader-task-settings/section-array.md)

**Example:**

```json
{
    "Section": "ST_BARCODE_DECODING",
    "ImageParameterName": "ip_dbrDefault",
    "StageArray": [
        {
            "Stage": "SST_RESIST_DEFORMATION"
        },
        {
            "Stage": "SST_DECODE_BARCODES"
        }
    ]
}
```

> [!NOTE]

## Parameters

### Section

Specifies the section type. Fixed value: `ST_BARCODE_DECODING`.

| Parameter Details |
| :------------- |
| **Type**<br>*string* |
| **Required**<br>Yes |
| **Default Value**<br>`"ST_BARCODE_DECODING"` |

### ImageParameterName

Specifies the name of an [ImageParameter](https://www.dynamsoft.com/capture-vision/docs/core/parameters/file/image-parameter.md) object to apply in the stages of this section.

| Parameter Details |
| :------------- |
| **Type**<br>*string* |
| **Range**<br>Must be the name of an [ImageParameter](https://www.dynamsoft.com/capture-vision/docs/core/parameters/file/image-parameter.md) object defined under `ImageParameterOptions` |
| **Default Value**<br>`""` |

### StageArray

Specifies the stage objects within this section. The `BarcodeDecodingSection` consists of the following stages:

| Stage | Description |
|-------|-------------|
| [ResistDeformationStage](https://www.dynamsoft.com/capture-vision/docs/core/parameters/reference/barcode-reader-task-settings/stage-resist-deformation.md) (`SST_RESIST_DEFORMATION`) | Applies preprocessing techniques to reduce image deformation and improve barcode recognition accuracy. |
| [ComplementBarcodeStage](https://www.dynamsoft.com/capture-vision/docs/core/parameters/reference/barcode-reader-task-settings/stage-complement-barcode.md) (`SST_COMPLEMENT_BARCODE`) | Defines configuration settings for the barcode complement process. |
| [ScaleBarcodeImageStage](https://www.dynamsoft.com/capture-vision/docs/core/parameters/reference/barcode-reader-task-settings/stage-scale-barcode-image.md) (`SST_SCALE_BARCODE_IMAGE`) | Scales the barcode image according to the specified scaling mode to optimize recognition. |
| [DecodeBarcodesStage](https://www.dynamsoft.com/capture-vision/docs/core/parameters/reference/barcode-reader-task-settings/stage-decode-barcodes.md) (`SST_DECODE_BARCODES`) | Extracts and interprets barcode data from the localized barcode regions. |
