Image Processing in Cloud via .Android/Java REST API

Aspose.Imaging Cloud is a true REST API that enables you to perform a wide range of image processing operations including creation, manipulation and conversion in the cloud, with zero initial costs. Our Cloud SDKs are wrappers around REST API in various programming languages, allowing you to process images in language of your choice quickly and easily, gaining all benefits of strong types and IDE highlights.

This repository contains test project and instructions on how to use Aspose.Imaging Cloud Java SDK for Android. This SDK allows you to work with Aspose.Imaging Cloud REST APIs in your Android applications quickly and easily, with zero initial cost.

To use this SDK, you will need Client ID and Client Secret which can be looked up at Aspose Cloud Dashboard (free registration in Aspose Cloud is required for this).

The solution uses Gradle Wrapper with no modifications.

Image Processing Features

• Fetch or update properties of cloud-hosted images.
• Scale, flip, crop, and export an image with a single API call.
• Resize, crop, flip, convert, and export an image to other supported formats.
• Update image parameters of JPEG2000 & WEBP images.
• Access and multi-frame TIFF image and extract the desired frames from it.
• Rotate, flip, crop, resize, or fetch properties of the selected TIFF frame.
• Merge multiple TIFF images.

Read & Write Image Formats

BMP, GIF, JPEG, JPEG2000, PSD, TIFF, WEBP, PNG, WMF, EMF, SVG, TGA, APNG

Save Image As

PDF, DICOM

DJVU, DICOM, CDR, CMX, ODG, DNG, EPS, EMZ, WMZ, SVGZ

Enhancements in Version 20.12

• Enhanced the EPS file format inheritance to support rotate, resize, flip, etc. operations as vector images support.
• Improved image loading, conversion, and export features.
• Added the JavaScript SDK.

Enhancements in Version 20.9

• Resumed the support of Android SDK and updated reference to Aspose.Imaging and Aspose.PSD.

Enhancements in Version 20.10

• Support for additional image formats in Object Detection.
• Support to load and convert EPS files to PDF/A format.

Storage API support

Since version 19.4, SDK includes support of storage operations for better user experience and unification, so now there's no need to use 2 different SDKs!

It gives you an ability to:

• Upload, download, copy, move and delete files, including versions handling (if you are using Cloud storage that supports this feature - true by default)
• Create, copy, move and delete folders
• Copy and move files and folders accross separate storages in scope of a single operation
• Check if certain file, folder or storage exists

Detailed official documentation can be found at the following link.

Getting Started

1. Sign Up. Before you begin, you need to sign up for an account on our Dashboard and retrieve your credentials.
2. Minimum requirements. This SDK requires Java 1.6 or later.
3. Add Aspose.Imaging Cloud Java SDK to your project. The project in this repo references Aspose.Imaging Cloud Java SDK either by placing the binary inside app/libs folder with manual handling of transitive dependenices (meant for internal usage only), or by simple addition of the repository dependency with configuring the project accordingly (user scenario) - the behavior is controlled with CI environment variable (see build.gradle). For the users, the following basic instructions should be applied.

Since this library is consuming Aspose.Imaging Cloud web APIs, please add INTERNET permission to your manifest.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.your.product.application">
	...
   <uses-permission android:name="android.permission.INTERNET" />
   ...
</manifest>

Add Aspose Cloud repository.

repositories {
    ...
    maven { url 'https://repository.aspose.cloud/repo/' }
    ...
}

Add dependency to Aspose.Imaging Cloud Java SDK, starting from 18.11 (previous versions may not work with Android).

dependencies {
    ...
    implementation group: 'com.aspose', name: 'aspose-imaging-cloud', version: '25.4'
    ...
}

4. Using the SDK. The best way to become familiar with how to use the SDK is to read the Developer Guide. The Getting Started Guide will help you to become familiar with the common concepts.

Quick Examples

Please, refer to Aspose.Imaging Cloud Java SDK examples.

Convert JPG to PNG in Android with Java

	// Get your ClientId and ClientSecret from https://dashboard.aspose.cloud (free registration required).
	ImagingApi api = new ImagingApi("MY_CLIENT_SECRET", "MY_CLIENT_ID");

	ConvertImageRequest request =  new ConvertImageRequest("sample.jpg", "png", "tempFolder", "My_Storage_Name");
	byte[] response = api.convertImage(request);

Aspose Cloud-hosted service VS on-premise deployment (experimental feature)

Starting from v19.7, you can choose either to use Aspose Cloud-hosted image processing service (the standard way) or the Docker image from Docker Hub deployed on-premise to serve the requests. The details about key differences and deployment process will be described on the dedicated Docker Hub page as soon as it's released. To succeed with your on-premise service usage by the SDK, you need to:

1. Use the new API class constructors with either single base URL parameter, or additional API version and debug mode parameters.

ImagingApi imagingApi = new ImagingApi("yourServiceUrl");

2. Set storage or storageName parameters for each request where they're present (mandatory!).
