In may this library won't be available from JCenter: https://jfrog.com/blog/into-the-sunset-bintray-jcenter-gocenter-and-chartcenter/

Please migrate this library to some other repository

my project use RxJava2.0.1, and i use this lib to handler image,. Then when i run my project like this: Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.

com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/rxjava.properties File1: /Users/envative/.gradle/caches/modules-2/files-2.1/io.reactivex/rxjava/1.1.6/2586312cd2b8a511e4c6236736f5a039fc0f2273/rxjava-1.1.6.jar File2: /Users/envative/.gradle/caches/modules-2/files-2.1/io.reactivex.rxjava2/rxjava/2.0.1/57f850a6b317e5582f1dbaff10a9e7d7e1fcdcfb/rxjava-2.0.1.jar

Create friendly "API" to compressor:

ImageCompressor.with(context)  
 .launchOn(Dispatchers.IO) // set a CoroutineContext (Optional, default = Dispatchers.IO)
 .observeOn(lifecycleScope) // set a CoroutineScope
 .applyCompressionWith { // options 
    resolution(1280, 720) 
    format(Bitmap.CompressFormat.WEBP) 
    ... 
 }.compress(inputImg) { outputImage -> 
    // get output image here 
 }

With that implementation is possible to use any DI framework to provide an ImageCompressor instance, enabling more reusability and decoupling of android Context.

See implementation here ImageCompressor.kt

i m Getting error in this line: Compressor.getDefault(this).compressToFileAsObservable(actualImage) .subscribeOn(Schedulers.io()) .observeOn(AndroidSchedulers.mainThread())

i m using android studio 2.3.1 and my project using this lib. compile 'io.reactivex.rxjava2:rxandroid:2.0.1' .

I am using 2.1.0 version.

Let's say I want to compress JPEG image and save it as a PNG after compression.

The problem is that newly created PNG file name persists the same with .jpg ending after such compression.

To avoid this, I have to do something like this:

.compressToFileAsFlowable(file, file.getName().replace(".jpg", ".png"))

which is not good in my opinion and such thing should be handled by library.

I am using RxJava 2.0.1 in my project and when i import Compressor it wont compile complaining i have multiple versions of RxJava.

We get this after pulling the artifact from Maven Central... In the pom file, you have a dependency called "unspecified", can you do an update which fixes this?

This is what the pom file looks like:

(We used another 3.0.0 version that didn't have any dependencies from Jcenter earlier)

I'm using this code to compress image, works fine till android 9 but on android 10 file size is of 0 bytes

try { new Compressor(this) //.setMaxWidth(640) // .setMaxHeight(480) // .setQuality(75) .setCompressFormat(Bitmap.CompressFormat.JPEG) .setDestinationDirectoryPath(new File(this.getExternalCacheDir(),"images").getAbsolutePath()) .compressToFile(new File(getPath(uri))); } catch (IOException e) { e.printStackTrace(); }

I have used it according to the documentation but when am compressing image to a specific size like 2mb it will not compress image exact to 2mb. It will give result like 1.1mb or something like that.

Caused by java.io.FileNotFoundException: /storage/emulated/0/Android/data/com.app.aexdriver.dev/files/Pictures/Camera/IMG_20220922_083206_502.jpg: open failed: ENOENT (No such file or directory)

Looking at source code of Compressor.compress and it's implementation down the line.

Seems like cache stays behind, if Exception occurs. Probably some sort of try-catch is needed, that deletes cached file in finally block.

Hi @zetbaitsu! Thank you for library. My question is how can we safely remove the cached file from the compressor folder? For example, I get images from outside, create a new file with name compressedImage , and set destination(imageFile) as the property, my newly created file is successfully replaced with the compressed one. But now we have 2 identical files in different folders. Would like to be able to properly delete a file coming along the path - "${context.cacheDir.path}${separator}compressor$separator".
