函数简介

截取绑定窗口指定区域的图像,并在独立窗口中弹窗显示,主要用于调试和测试阶段。

接口名称

ShowImageFromWindow

DLL调用

int ShowImageFromWindow(long instance, int x1, int y1, int x2, int y2);

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。
x1整数型窗口左上角 X 坐标
y1整数型窗口左上角 Y 坐标
x2整数型窗口右下角 X 坐标
y2整数型窗口右下角 Y 坐标

示例

SDK 调用

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int ret = ola.ShowImageFromWindow(0, 0, 0, 0);
csharp
using OLAPlug;

var ola = new OLAPlugServer();
int ret = ola.ShowImageFromWindow(0, 0, 0, 0);
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
ret = ola.ShowImageFromWindow(0, 0, 0, 0)
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
int ret = ola.ShowImageFromWindow(0, 0, 0, 0);
cpp
var ola = com("OlaPlug.OlaSoft")
var ret = ola.ShowImageFromWindow(0, 0, 0, 0)
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
ret = ola.ShowImageFromWindow(0, 0, 0, 0)
text
.局部变量 ola, OLAPlug
ola.创建 ()
ret = ola.ShowImageFromWindow(0, 0, 0, 0)
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var ret = ola.ShowImageFromWindow(0, 0, 0, 0);
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
整数 ret = ola.ShowImageFromWindow(0, 0, 0, 0)
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int32_t ret = ola.ShowImageFromWindow(0, 0, 0, 0);

原生 DLL 调用

cpp
long instance = CreateCOLAPlugInterFace();
ShowImageFromWindow(instance, 0, 0, 0, 0);
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 ShowImageFromWindow(long ola, int x1, int y1, int x2, int y2);

long instance = CreateCOLAPlugInterFace();
ShowImageFromWindow(instance, 0, 0, 0, 0);
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.ShowImageFromWindow(instance, 0, 0, 0, 0)

返回值

整数型:1 成功,0 失败。

注意事项

  • 需先绑定窗口,否则无法正确截取窗口区域图像。
  • 坐标为绑定窗口客户区坐标,与 获取指定区域图象 - GetScreenDataPtr 一致。
  • 此函数主要用于调试和测试,不建议在生产环境中使用。
  • 显示的图片窗口可能需要用户手动关闭。
