Image Processing in web api or in C#

I checked your images and I think you want to apply similar effects over images using your web-application. Is this correct?
If yes, you can try the JavaScript image processing functions from LEADTOOLS and use them in your C# ASP.NET application at the client side.
More details can be found here:
https://www.leadtools.com/help/leadtools/v20/dh/javascript/to/leadtools-javascript-image-processing.html
Also, you can find an online demo here:
http://demo.leadtools.com/JavaScript/ImageProcessing/

Note that if you prefer applying these image processing functions at the server side directly using .NET classes, you can also using LEADTOOLS .NET Image processing functions.

For example, the following code shows how you can apply the Sepia effect over your images:

using (RasterCodecs _codecs = new RasterCodecs())
{
//The following code changes the non-white pixels in the image to different RasterImage colors and keeps //the white pixels unchanged
RasterImage TestImage = _codecs.Load(@"C:\Source\Src1.tif");
//Add a region to the image that contains all non-white pixels
TestImage.AddColorToRegion(Leadtools.RasterColor.White, RasterRegionCombineMode.SetNot);
//Use the following code if the background color is black
//TestImage.AddColorToRegion(RasterColor.Black, //RasterRegionCombineMode.SetNot);
//Colorize the non-white pixels to get the Sepia effect
var command = new Leadtools.ImageProcessing.Color.ConvertToColoredGrayCommand();
//These arguments will transform the image into a grayscale image.
command.RedFactor = 300;
command.GreenFactor = 300;
command.BlueFactor = 200;
command.RedGrayFactor = 350;
command.GreenGrayFactor = 100;
command.BlueGrayFactor = -100;
command.Run(TestImage);
_codecs.Save(TestImage, @"C:\Target\Res1.tif", RasterImageFormat.Tif, 24);
}

Simple photo to another photo means?
Do you want to resize photo?
