Picfit

An lightweight image resizing server written in C# .NET Core

Picfit is a reusable .NET Core server to upload images with scale preprocessing. I selected preprocessing workflow beacause postprocessing more expensive. Picfit will supports multiple storage backends and multiple processing implementations.

I could not come up with a good name for this application so I used picfit name

}

storage can be:

• type:fs - generated images stored in your File system
• type:s3 - generated images stored in Amazon S3 (in the future)
• type:... - you can write custom implementation
• location - folder location for fs type

imagepreprocessing can be:

• type:imagesharp - use SixLabors/ImageSharp library to rescale images
