### SDK API Introduction

Source: https://docs.google.com/document/d/e/2PACX-1vQ3M0KV9am29GTKFGmb0dwSFyQAZVFmwDmYA6846pvDPTC3yhN0ZGlBWs-yRjyVYg/pub/index

This section introduces the SDK API definition and provides corresponding examples. It outlines the process flow for using the SDK, emphasizing considerations for asynchronous (with Callback) and synchronous scanning to ensure proper functioning.

```APIDOC
## SDK API Introduction

### Description
This chapter introduces the SDK API definition and provides corresponding examples. To use the SDK, please ensure the following process flow:

### Asynchronous Scan (with Callback)
If you use asynchronous AsychronizeScan (with Callback), please integrate Device Control and Callback process into the Main Form (Main Thread) of the main window, which can ensure Callback to work normally when it returns.

### Synchronous Scan (without Callback)
If only Device Control can be integrated into the Sub Form (Sub Thread) in your process, please use the SynchronizeScan (without Callback), which can ensure to obtain the correct relevant image data synchronously after scanning.
```

Occurs when no recognition tool has been configured. Verify that the `initEx()` parameter is set to `LIBWFX_INIT_MODE_NORMAL` (using C++ as an example).

```APIDOC
## OCR_TOOL_NOT_SUPPORT

### Description
No recognition tool has been set. Please check whether the parameter of initEx() is LIBWFX_INIT_MODE_NORMAL (C++ is used as an example herein).

### Method
