翻转图像 - Flip

函数简介

按照给定翻转代码对图像进行翻转。

接口名称

Flip

DLL调用

int64_t Flip(int64_t instance, int64_t ptr, int32_t flipCode);

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。
ptr长整数型图像指针
flipCode整数型翻转代码:0 X轴翻转、1 Y轴翻转、2 同时翻转

示例

SDK 调用

cpp
#include "OLAPlugServer.h"

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

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

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

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

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

原生 DLL 调用

cpp
Flip(instance, 0, 0);
csharp
using System.Runtime.InteropServices;
using System.Text;

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int Flip(long ola, int ptr, int flipCode);

Flip(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
ola.Flip(instance, 0, 0)

返回值

长整数型:返回翻转后的图像句柄,失败返回0。

注意事项

  • 返回的图像需调用 FreeImagePtr 释放内存。
