获取OCR模型推理配置 - OcrGetModelConfig ​

函数简介 ​

读取已加载 OCR 模型当前合并后的推理配置（PascalCase JSON）。

接口名称 ​

OcrGetModelConfig

DLL 调用 ​

long OcrGetModelConfig(long ola, long modelHandle);

参数说明 ​

参数名类型说明
ola长整数型OLAPlug 对象指针。
modelHandle长整数型模型句柄；内置 mobile 为 0。

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
std::string result = ola.OcrGetModelConfig(0);
csharp
using OLAPlug;

var ola = new OLAPlugServer();
string result = ola.OcrGetModelConfig(0);
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
result = ola.OcrGetModelConfig(0)
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
String result = ola.OcrGetModelConfig(0);
go
import "github.com/ola/olaplug/olaplug"

ola, _ := olaplug.NewOLAPlugServer("OLAPlug_x64.dll")
defer ola.ReleaseObj()
result := ola.OcrGetModelConfig(0)
rust
use olaplug::OLAPlugServer;

let ola = OLAPlugServer::new("OLAPlug_x64.dll").unwrap();
let result = ola.ocr_get_model_config(0);
cpp
var ola = com("OlaPlug.OlaSoft")
var result = ola.OcrGetModelConfig(0)
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
result = ola.OcrGetModelConfig(0)
text
.局部变量 ola, OLAPlug
ola.创建 ()
result ＝ ola.OcrGetModelConfig(0)
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var result = ola.OcrGetModelConfig(0);
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
文本型 result = ola.OcrGetModelConfig(0)
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
std::string result = ola.OcrGetModelConfig(0);

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
long ptr = OcrGetModelConfig(instance, 0);
if (ptr != 0) {
    char buffer[512] = {0};
    GetStringFromPtr(ptr, buffer, sizeof(buffer));
    FreeStringPtr(ptr);
}
csharp
using System.Runtime.InteropServices;
using System.Text;

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long CreateCOLAPlugInterFace();
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int GetStringFromPtr(long ptr, StringBuilder lpString, int size);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int FreeStringPtr(long ptr);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int GetStringSize(long ptr);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long OcrGetModelConfig(long ola, long modelHandle);

long instance = CreateCOLAPlugInterFace();
long ptr = OcrGetModelConfig(instance, 0);
if (ptr != 0) {
    StringBuilder sb = new StringBuilder(GetStringSize(ptr) + 1);
    GetStringFromPtr(ptr, sb, sb.Capacity);
    FreeStringPtr(ptr);
    string result = sb.ToString();
}
python
from ctypes import CDLL, c_int, c_int64, create_string_buffer

ola = CDLL("OLAPlug_x64.dll")
ola.CreateCOLAPlugInterFace.restype = c_int64
instance = ola.CreateCOLAPlugInterFace()
ptr = ola.OcrGetModelConfig(instance, 0)
if ptr:
    buf = create_string_buffer(512)
    ola.GetStringFromPtr(ptr, buf, 512)
    ola.FreeStringPtr(ptr)
    result = buf.value.decode("utf-8")

返回值 ​

返回值说明
（返回值）字符串指针。成功时 Success=true，并含 ModelHandle、BackendId、Runtime 及调参字段；失败时 {"Success":false,"Error":"..."}。 须 FreeStringPtr 释放。

注意事项 ​
