接口名称 ​

SetColorsToNewColor

DLL调用 ​

int SetColorsToNewColor(long ola, long image_ptr, string colors_json, string new_colors);

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_ptr长整数型要修改的图片句柄
colors_json字符串颜色模型配置字符串，格式说明见 颜色模型说明 - ColorModel。JSON格式示例：[{"StartColor":"3278FA","EndColor":"6496FF","Type":0}]；简化格式示例：3278FA~6496FF
new_colors字符串要设置的新颜色值，支持ARGB格式如"#FFFFFFFF"或"#FFFFFF"

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
long handle = ola.SetColorsToNewColor(0, "value", "value");
csharp
using OLAPlug;

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

ola = OLAPlugServer()
handle = ola.SetColorsToNewColor(0, "value", "value")
java
import com.olaplug.OLAPlugServer;

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

OLAPlugServer ola;
long handle = ola.SetColorsToNewColor(0, "value", "value");

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
SetColorsToNewColor(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 SetColorsToNewColor(long ola, long image_ptr, string colors_json, string new_colors);

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

返回值 ​

整数型：1 成功，0 失败。

注意事项 ​

  • 处理大图片时，较大的颜色范围可能会增加处理时间。
