I have a client who currently is able to upload graphic file(s) to his website for display. My client is a restaurant owner and, as I believe most clients would agree, does not want to be bogged down with graphic file size do to DPI or dimensions of the the graphic.

I use VB.NET and Visual Studio Pro 2017.

I would like to manipulate the DPI and graphic dimensions for him. What I need to adjust are:
  • DPI
  • width or length keeping the aspect ratio of the graphic

I am not savvy when it comes to graphic files. I do know how to gain addressability to the graphic file IO stream after upload.

I need mentoring on how to do these two things and save the graphic file as a smaller version of itself.

Any assistance is greatly appreciated.

Much thanks,
David Bach
