Canvas resize feature lets your user set the size of the postcard or cover letter from the product designer tool. The admin just has to create the custom templates from the backend, so that the shopper can apply them on the frontend.
Now the customers can apply the canvas resize templates as per their choice. They can change the size of the canvas to make it appear visually better.
Your user can select the parameter of the size as well for the canvas from Pixel, inch, centimeter, and Meter.
Not only this they can even create the canvas by entering the custom value of width and height.
Note: The entered value of the width and height of the canvas will be based on the parameter you have selected above.
