移除图片差异部分 - RemoveImageDiff ​

函数简介 ​

比较两张图片，将差异部分设置为透明，保留完全相同的部分。

接口名称 ​

RemoveImageDiff

DLL调用 ​

long RemoveImageDiff(long ola, long imgPtr1, long imgPtr2);

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。
imgPtr1长整数型第一张图片的OLAImage对象地址
imgPtr2长整数型第二张图片的OLAImage对象地址

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
long handle = ola.RemoveImageDiff(0, 0);
csharp
using OLAPlug;

var ola = new OLAPlugServer();
long handle = ola.RemoveImageDiff(0, 0);
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
handle = ola.RemoveImageDiff(0, 0)
java
import com.olaplug.OLAPlugServer;

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

OLAPlugServer ola;
long handle = ola.RemoveImageDiff(0, 0);

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
RemoveImageDiff(instance, 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 long RemoveImageDiff(long ola, long imgPtr1, long imgPtr2);

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

返回值 ​

长整数型：成功返回处理后的OLAImage对象地址，失败返回0。

注意事项 ​

  • 两张图片必须具有相同的尺寸。
  • 原始图片不会被修改，返回新的图片对象。
  • 返回的图片需调用 FreeImagePtr 释放内存。
