API endpoint : resize the image and return it back

Question

Hi All,

I am looking ahead to develop a WEBAPI EndPoint which accepts an Image, Resize it and return it back.

Please find the minute details below.

API Request Parameters

a)A Design ID of the Image,
b)Image Type
c)@ItemType parameter (Need to actually use it in a function called GetItemLocation)

Explanation of Function dbo.fn_GetItemLocation

This Function would pull the design location on the network based on @ItemType parameter and return the URI Filepath using which we would grab the design Image, resize it(Lets say any small size) and return it.

So Below are the contents which I want to return

API Response Parameters

a)Design ID
b)Blob with the file contents (resized)
c)field that states if it is a PNG or JPEG

What Would API Consumer do ?

Consumer would get the image for a design ID and then renders it and use it in whatever way he wants.

Please note that I just need any article or any guidance so that I can approach to start this thing up.

Hi. First of all, When you will create WebApi at that time you need to take one parameter as byte[]. By using those byte[] you need to convert into an image and need to save in a path. For converting byte[] to image and save in a path you can use this code, string hasil = "D:\coba1000.jpg"; System.IO.File.WriteAllBytes(@hasil, bytestosend); You can follow this article for more, https://stackoverflow.com/questions/9173904/byte-array-to-image-conversion After that next step is, you need to resize the image and for that you can follow these tutorials, https://www.c-sharpcorner.com/blogs/resizing-image-in-c-sharp-without-losing-quality1 https://www.c-sharpcorner.com/article/resize-image-in-c-sharp/ After resizing the image, again you need to convert that image into byte[] and you need to return that byte[] in webapi. For Converting Image into byte[] you can use this code, public byte[] imageToByteArray(Image imageIn) { MemoryStream ms = new MemoryStream(); imageIn.Save(ms,System.Drawing.Imaging.ImageFormat.Gif); return ms.ToArray(); } For more you can follow this link, https://stackoverflow.com/questions/9173904/byte-array-to-image-conversion At last, the api where you will consume you need to get that byte[] and based on that you need to do processing. Whatever, i explained here, by using this you need to do all your workaround code. Let me know if you need any help. Thanks.
