Dynamic Image Scaling

What are the trade offs when an image is scaled from one size to another on the fly?
For example - I am using an image in a rectangle. If I increase the width of the rectangle, I want to increase the width of the image also. An animation is used to show the change in width.
I want to understand performance issues, when image's width is also changed, how does it impact memory usage. How many copies of image is stored in memory?
Hi and welcome to devnet,
What are you using to display the image ?
How are you rescaling it ?

@SGaist Thank you!
I am using qml's Image element and a png file as source.
It's just a gradient image which I am using as the rectangle's border. I am using 1px width image and using the fillMode for the image's width to grow with the width of the rectangle.
Can you show how you do it ?
