Image Compressor

An Android image compress library, image compressor, is small and effective. With very little or no image quality degradation, a compressor enables you to reduce the size of large photos into smaller size photos.

How to implement

To get a Git project into your build:

Gradle

Step 1: Add it in your root build.gradle at the end of repositories:

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

Step 2: Add the dependency in your project build.gradle

dependencies {
	        implementation 'com.github.vinodbaste:ImageCompressor:1.1.0'
	}

Let's compress the image size!

Compress Image File at the specified imagePath

When compressing a picture, add the following block of code to the activity or fragment. Either after taking a picture with a camera or selecting one from a gallery.

ImageCompressUtils.compressImage(
            context = this,
            imagePath = "actualImagePath",
            imageName = "imageName",
            imageQuality = 50
        )

compressImage takes 4 parameters where the last one is optional

• context, the current/active state of the application.
• imagePath parameter takes the absolute image path.
• imageName is completely up to the user.
• imageQuality is set to 50 by default. The max can be set to 100.

Compress Image File at the specified imagePath and return the compressed ImagePath

val compressedImagePath = ImageCompressUtils.compressImage(
            context = this,
            imagePath = "actualImagePath",
            imageName = "imageName",
            imageQuality = 50
        )

With the image name supplied, the code block above returns the path to the compressed picture. compressedImagePath has the imagePath with the imageName specified.

Example

An illustration of how the code block can be utilized.

 	 //absolute path of the image
        val imagePath= "actualImagePath"

        val imageFileBc = File(imagePath)
        val imageSizeBc = imageFileBc.length() / 1024 // In BYTES
        Log.d("image_before_compress", imageSizeBc.toString())

        ImageCompressUtils.compressImage(
            context = this,
            imagePath = imagePath,
            imageName = "imageName",
            imageQuality = 50
        )

        val imageFileAc = File(imagePath)
        val imageSizeAC = imageFileAc.length() / 1024 // In BYTES
        Log.d("image_after_compress", imageSizeAC.toString())

        //your function to play with compressed image
        loadCompressedImage(imagePath)

> In the event that an image is selected from a gallery, make a copy of it and follow the path.
> The original picture path is used to compress and rewrite the image.
