参数说明 ​

参数名类型说明
instance长整数型OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。
file字符串图片文件路径，支持相对路径和绝对路径

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int ret = ola.ShowImageFromFile("C:\\test.txt");
csharp
using OLAPlug;

var ola = new OLAPlugServer();
int ret = ola.ShowImageFromFile("C:\\test.txt");
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
ret = ola.ShowImageFromFile("C:\\test.txt")
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
int ret = ola.ShowImageFromFile("C:\\test.txt");
cpp
var ola = com("OlaPlug.OlaSoft")
var ret = ola.ShowImageFromFile("C:\\test.txt")
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
ret = ola.ShowImageFromFile("C:\\test.txt")
text
.局部变量 ola, OLAPlug
ola.创建 ()
ret ＝ ola.ShowImageFromFile(“C:\\test.txt”)
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var ret = ola.ShowImageFromFile("C:\\test.txt");
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
整数 ret = ola.ShowImageFromFile("C:\\test.txt")
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int32_t ret = ola.ShowImageFromFile("C:\\test.txt");

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
ShowImageFromFile(instance, "C:\\test.txt");
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 ShowImageFromFile(long ola, string file);

long instance = CreateCOLAPlugInterFace();
ShowImageFromFile(instance, "C:\\test.txt");
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()
ola.ShowImageFromFile(instance, "C:\\test.txt")

返回值 ​

整数型：1 成功，0 失败。

注意事项 ​

  • 如果文件不存在或格式不支持，函数将返回失败。
  • 显示的图片窗口可能需要用户手动关闭。
