We install windows and doors for the public. We would like an app which allows the customer to take a picture of a house, draw a rectangle around the windows and doors. Measure and enter the sizes of the windows and doors. Drop in windows from a catalogue of images to help show the customer visualise what they will get. Auto scale thee windows in the picture boxes. Create a summary of items with sizes. Save the information to a database, send the finished picture to the customer. Look at the uploaded files for a full explanation.
