指定区域数据是否卡屏 - IsDisplayDead ​

函数简介 ​

判断指定区域在指定时间内图像数据是否一直不变（卡屏），没有卡屏立马返回。

接口名称 ​

IsDisplayDead

DLL调用 ​

int IsDisplayDead(long ola, int x1, int y1, int x2, int y2, int time);

参数说明 ​

参数名类型说明
ola长整数型OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。
x1整数型查找区域的左上角X坐标
y1整数型查找区域的左上角Y坐标
x2整数型查找区域的右下角X坐标
y2整数型查找区域的右下角Y坐标
time整数型识别间隔，单位毫秒

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

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

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

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

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

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

原生 DLL 调用 ​

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

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

返回值 ​

整数型：0 正常，1 卡屏。

注意事项 ​

  • x1, y1, x2, y2 全传0时检测窗口整个客户区。
  • 绑定的窗口不存在也返回1。
