NDKProcessImage

Introduction

使用 NDKProcessImage 实现对图片基本处理，可以用来实现对bitmap的对比度调节、亮度调节、旋转、镜像、高斯模糊、yuv和rgb格式互转等。

Features

• 支持对比度调节
• 支持亮度调节
• 支持旋转
• 支持镜像
• 支持高斯模糊
• 支持yuv和rgb数据互转

Getting started

在项目的根节点的 build.gradle 中添加如下代码

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

在项目的 build.gradle 中添加

dependencies {
    implementation 'com.github.Kebiiii:NDKProcessImage:v1.0.2'
}

Usage

1. 设置bitmap的亮度和对比度：

• 亮度范围：0-1.0f
• 对比度范围：-1.0f-1.0f

mBitmap = NativeImageUtils.brightnessContrastChange(mOriginalBitmap, brightness, contrast);
imageView.setImageBitmap(mBitmap);

2. 对图片的argb数据图像加深：相当于亮度设置为0.2f对比度设置0.2f：

int[] result = NativeImageUtils.deepImage(buffer, mBitmap.getWidth(), mBitmap.getHeight());

3. argb2Yuv： 图片的argb数据转为yuv格式：

byte[] yuvData = NativeImageUtils.argb2Yuv(data,width,height);

4. yuv420sp2rgb： 图片的yuv格式转为rgb数据：

int[] data = NativeImageUtils.yuv420sp2rgb(yuvData,width,height);

5. gaussBlur: 对bitmap图片进行高斯模糊处理：

• radius： 模糊半径

mBitmap = NativeImageUtils.gaussBlur(mBitmap,30);
imageView.setImageBitmap(mBitmap);

6. rotateBitmap: 对bitmap图片90度旋转顺时针：

mBitmap = NativeImageUtils.rotateBitmap(mBitmap);
imageView.setImageBitmap(mBitmap);

7. convertBitmap: 对bitmap图片上下镜像处理：

mBitmap = NativeImageUtils.convertBitmap(mBitmap);
imageView.setImageBitmap(mBitmap);

8. mirrorBitmap: 对bitmap图片左右镜像处理：

mBitmap = NativeImageUtils.mirrorBitmap(mBitmap);
imageView.mirrorBitmap(mBitmap);
