Introduce

Tiny does not depend on any library , it keeps the code clean on architecture . Tiny also uses an asynchronous thread pool to compress images , and will hand out the result in the main thread when compression is completed.

Usage

Installation

implementation 'com.zxy.android:tiny:1.0.0'

Choose an abi

Tiny provide abi：armeabi、armeabi-v7a、arm64-v8a、x86.

Choose what you need "abi" version：

android {
    defaultConfig {
        ndk {
            abiFilters 'armeabi','x86'//or armeabi-v7a、arm64-v8a、x86
        }
    }
}

Initialization

        Tiny.getInstance().init(this);

Compression

AsBitmap

        Tiny.BitmapCompressOptions options = new Tiny.BitmapCompressOptions();
        //options.height = xxx;//some compression configuration.
        Tiny.getInstance().source("").asBitmap().withOptions(options).compress(new BitmapCallback() {
            @Override
            public void callback(boolean isSuccess, Bitmap bitmap, Throwable t) {
                //return the compressed bitmap object
            }
        });
        
        //or sync compress.
        BitmapResult result = Tiny.getInstance().source("").asBitmap().withOptions(options).compressSync();

AsFile

        Tiny.FileCompressOptions options = new Tiny.FileCompressOptions();
        Tiny.getInstance().source("").asFile().withOptions(options).compress(new FileCallback() {
            @Override
            public void callback(boolean isSuccess, String outfile, Throwable t) {
                //return the compressed file path
            }
        });
        
        //or sync compress.
        FileResult result = Tiny.getInstance().source("").asFile().withOptions(options).compressSync();

AsFileWithReturnBitmap

        Tiny.FileCompressOptions options = new Tiny.FileCompressOptions();
        Tiny.getInstance().source("").asFile().withOptions(options).compress(new FileWithBitmapCallback() {
            @Override
            public void callback(boolean isSuccess, Bitmap bitmap, String outfile, Throwable t) {
                //return the compressed file path and bitmap object
            }
        });
        
        //or sync compress.
        FileWithBitmapResult result = Tiny.getInstance().source("").asFile().withOptions(options).compressWithReturnBitmapSync();

BatchAsBitmap

        Tiny.BitmapCompressOptions options = new Tiny.BitmapCompressOptions();
        Tiny.getInstance().source("").batchAsBitmap().withOptions(options).batchCompress(new BitmapBatchCallback() {
            @Override
            public void callback(boolean isSuccess, Bitmap[] bitmaps, Throwable t) {
                //return the batch compressed bitmap object
            }
        });
        
        //or sync compress.
        BitmapBatchResult result = Tiny.getInstance().source("").batchAsBitmap().withOptions(options).batchCompressSync();

BatchAsFile

        Tiny.FileCompressOptions options = new Tiny.FileCompressOptions();
        Tiny.getInstance().source("").batchAsFile().withOptions(options).batchCompress(new FileBatchCallback() {
            @Override
            public void callback(boolean isSuccess, String[] outfile, Throwable t) {
                //return the batch compressed file path
            }
        });
        
        //or sync compress.
        FileBatchResult result = Tiny.getInstance().source("").batchAsFile().withOptions(options).batchCompressSync();

BatchAsFileWithReturnBitmap

        Tiny.FileCompressOptions options = new Tiny.FileCompressOptions();
        Tiny.getInstance().source("").batchAsFile().withOptions(options).batchCompress(new FileWithBitmapBatchCallback() {
            @Override
            public void callback(boolean isSuccess, Bitmap[] bitmaps, String[] outfile, Throwable t) {
                //return the batch compressed file path and bitmap object
            }
        });
        
        //or sync compress.
        FileWithBitmapBatchResult result = Tiny.getInstance().source("").batchAsFile().withOptions(options).batchCompressWithReturnBitmapResult();
