设置图片指定坐标集的颜色 - SetPixelList ​

函数简介 ​

批量设置图片中多个指定坐标点的颜色为新的颜色值。

接口名称 ​

SetPixelList

DLL调用 ​

int SetPixelList(long ola, long image, string points, string color);

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。
image长整数型OLAImage对象的地址
points字符串坐标集的JSON字符串，格式如：[{"x":0,"y":0},{"x":1,"y":1}]
color字符串要设置的颜色值，支持ARGB格式如"#FFFFFFFF"或"#FFFFFF"

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int ret = ola.SetPixelList(0, "[{", "#FFFFFFFF");
if (ret == 1) {
    // 操作成功
}
csharp
using OLAPlug;

var ola = new OLAPlugServer();
int ret = ola.SetPixelList(0, "[{", "#FFFFFFFF");
if (ret == 1)
{
    // 操作成功
}
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
ret = ola.SetPixelList(0, "[{", "#FFFFFFFF")
if ret == 1:
    pass  # 操作成功
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
int ret = ola.SetPixelList(0, "[{", "#FFFFFFFF");
if (ret == 1) {
    // 操作成功
}
cpp
var ola = com("OlaPlug.OlaSoft")
var ret = ola.SetPixelList(0, "[{", "#FFFFFFFF")
if(ret == 1) {
    // 操作成功
}
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
ret = ola.SetPixelList(0, "[{", "#FFFFFFFF")
If ret = 1 Then
    ' 操作成功
End If
text
.局部变量 ola, OLAPlug
ola.创建 ()
ret ＝ ola.SetPixelList(0, “[{”, “#FFFFFFFF”)
.如果真 (ret ＝ 1)
    ' 操作成功
.如果真结束
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var ret = ola.SetPixelList(0, "[{", "#FFFFFFFF");
if(ret == 1){
    // 操作成功
}
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
整数 ret = ola.SetPixelList(0, "[{", "#FFFFFFFF")
如果真 (ret ＝ 1)
{
    // 操作成功
}
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int32_t ret = ola.SetPixelList(0, "[{", "#FFFFFFFF");
if (ret == 1) {
    // 操作成功
}

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
SetPixelList(instance, 0, "[{", "#FFFFFFFF");
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 SetPixelList(long ola, long image, string points, string color);

long instance = CreateCOLAPlugInterFace();
SetPixelList(instance, 0, "[{", "#FFFFFFFF");
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.SetPixelList(instance, 0, "[{", "#FFFFFFFF")

返回值 ​

整数型：1 成功，0 失败。

注意事项 ​

  • 原始图片会被直接修改。
  • 比多次调用 SetPixel 更高效。
