截图返回字节流 - GetScreenDataBmp

函数简介

获取指定区域的图像数据,以BMP格式二进制数据返回。此接口线程不安全,不推荐使用。

接口名称

GetScreenDataBmp

DLL调用

int GetScreenDataBmp(long ola, int x1, int y1, int x2, int y2, long* data, int* size);

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整数型区域的左上X坐标
y1整数型区域的左上Y坐标
x2整数型区域的右下X坐标
y2整数型区域的右下Y坐标
data长整数型指针返回BMP图片数据的指针地址
size整数型指针返回BMP图片数据的总长度(字节数)

示例

SDK 调用

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int ret = ola.GetScreenDataBmp(0, 0, 0, 0, "value", "value");
csharp
using OLAPlug;

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

ola = OLAPlugServer()
ret = ola.GetScreenDataBmp(0, 0, 0, 0, "value", "value")
java
import com.olaplug.OLAPlugServer;

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

OLAPlugServer ola;
int32_t ret = ola.GetScreenDataBmp(0, 0, 0, 0, "value", "value");

原生 DLL 调用

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

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

返回值

整数型:1 成功,0 失败。

注意事项

  • 此接口线程不安全,建议使用 GetScreenDataPtr + GetImageBmpData + FreeImagePtr 替代。
  • 返回的数据是标准BMP文件格式,包含BMP文件头。
  • 数据指针在下次调用前有效,需及时拷贝数据。
  • x1, y1, x2, y2 全传0时获取窗口整个客户区。
