Steps to Deskew JPEG via Java Cloud API
Developers can easily load & deskew JPEG files in just a few lines of code.
- Load JPEG file as stream
- Create & set the instance of CreateDeskewedImageRequest
- Set resize proportionally and back color
- Call the CreateDeskewedImage method
- Get deskewed image from response stream
System Requirements
Aspose.Imaging Cloud for Java is supported on all major operating systems. Just make sure that you have the following prerequisites.
- JDK 1.6 or higher is installed.

About Aspose.Imaging Cloud API for Java
Aspose.Imaging Cloud API is an image processing solution to process images (photos) within your cloud or web applications. It offers: cross-platform Image processing, including but not limited to conversions between various image formats (including uniform multi-page or multi-frame image processing), transformations (resize, crop, flip&rotate, grayscale, adjust), advanced image manipulation features (filtering, deskewing), AI features (i.e. object detection and reverse image search). It’s a Cloud API and does not depend on any software for image operations. One can easily add high-performance image conversion features with Cloud APIs within projects. Flexible integrations options including SDKs for various languages (Python, Ruby, .NET, Java, NodeJS, PHP) and the use of the REST API allow to make the integration easy.

JPEG What is JPEG File Format
A JPEG is a type of image format that is saved using the method of lossy compression. The output image, as result of compression, is a trade-off between storage size and image quality. Users can adjust the compression level to achieve the desired quality level while at the same time reduce the storage size. Image quality is negligibly affected if 10:1 compression is applied to the image. The higher the compression value, the higher the degradation in image quality.
