Convert 4*4 array into matrix form and vice versa ?

[milindsakhare100]

How can I convert a 4*4 array into a matrix?

For example,

toM4(matrix.value)

Converts matrix into an array. I need inverse of the above example. How can I achieve it? Please help

The PR you sent is bit difficult to understand for me. Is there any documentation? If yes please provide me. Thanks

It would be easier if you would share information on what you are trying to achieve

Hi @wcandillon , I am working on a poster making application. Where I implemented your Instagram example.

As shown in your Instagram example we can translate, scale and rotate the image/sticker.

But my problem is, I want to save stickers/images with their respective co-ordinates as draft, so that I can start from where I left the editing of stickers/images.

With the new skia update I am unable to do it.
Please update Instagram example with latest skia. And please add one more feature in the example that is draft editing as I mentioned above.

I hope you get the point.
Thanks.
