拷贝图片 - CopyImage

函数简介

创建图片的完整副本,生成一个具有相同内容的新图片对象。

接口名称

CopyImage

DLL调用

long CopyImage(long ola, long imagePtr);

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。
imagePtr长整数型要复制的OLAImage对象的地址

示例

SDK 调用

cpp
#include "OLAPlugServer.h"

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

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

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

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

OLAPlugServer ola;
long handle = ola.CopyImage(0);

原生 DLL 调用

cpp
long instance = CreateCOLAPlugInterFace();
CopyImage(instance, 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 CopyImage(long ola, long imagePtr);

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

返回值

长整数型:成功返回复制的OLAImage对象的地址,失败返回0。

注意事项

  • 复制后的图片与原图完全独立,修改一个不会影响另一个。
  • 返回的图片需调用 FreeImagePtr 释放内存。
