• based on Reactive Stream API (RxJava2) and Thumbnailator
• On the fly image processing such as image cropping or water mark adding by just change image request url. that's all.

please wait...

For example, you want to store image and serve cropped 500x500 image in your home page.

1. Once you persist image, you will get imageId. store in somewhere. For example, in your Article table.
2. And then request image to this pattern [/contextPath][/WebThumbnailatorBaseUrl]/filterName/imageId

Let's assume that you have

• example.com as your host name.
• /sampleApp as your contextPath.
• /images as a Web-Thumbnailator baseUrl.
• crop_500x500 as your filter name to crop image to 500x500
• /my/image/id/sample-article.jpg as your imageId

then the url to serve the image which will be cropped to 500 x 500 would be http://example.com/sampleApp/images/crop_500x500/my/image/id/sample-article.jpg

//TODO

Go to spring-boot module

Go to servlet module

//TODO

when you define filter in configuration, you must define in list which will be trigger in chain. for example, your first filter may crop image and then your 2nd one will rotate your image.

1. io.prime.web.thumbnailator.filter.CropFilter //TODO add more filter

You can create your own filter by implements interface ThumbnailatorFilter and then add your implementation into configuration. For more information about how to define your own filter, please read more about Thumbnailator

1. Just autowire io.prime.web.thumbnailator.util.ThumbnailatorUtil
2. And then you can persist image using variety of overload methods of ThumbnailatorUtil.create()
3. Once you persisted your image, you will get imageId as a String. store it wherever you want.

Once you autowire io.prime.web.thumbnailator.util.ThumbnailatorUtil then you can use

• ThumbnailatorUtil.create() to persist image
• ThumbnailatorUtil.get() to get filtered image
• ThumbnailatorUtil.getSource() to get source image

• need to review and do some tweaks before releasing.
• change to full async on processing request
• provide full configuration on every part of this project.
