## unity – Display/hide image with zoom in/out

After spending a while looking through the forums, I haven’t been able to find a thread that deals with transforms on an image.

Essentially, what I’m trying to do is display and hide an image at the start of a level in a game I’m working on. The image should start out large and with 100% transparency, then shrink to a certain size within the camera bounds with no transparency, idle for a second, then fade back out the way it came.

How would this be done programmatically? Thanks in advance!

## algorithms – Filling a hole in an image in O(nlogn)

I have a grayscale image (given by a float matrix with values between (0, 1)) with a hole in it (a cluster of pixels/cells with values of -1).

Definitions:

The `boundary` of the hole as all the cells that are 4-connected to a hole pixel (a pixel with -1 value) (you can read more about pixel connectivity here: https://en.wikipedia.org/wiki/Pixel_connectivity).

`I(v)` is the color of the pixel v.

I need the fill the hole using this formula:

Denote the `boundary` with B. So for each u – hole pixel:

$$begin{equation} I(u) = frac{Sigma_v{_in}_B w(u,v) * I(v))}{Sigma_v{_in}_B w(u,v)} end{equation}$$
Where w is some arbitrary weighting function (for example using euclidean distance)

$$begin{equation} w(v,u) = frac{1}{|| u – v||} end{equation}$$
Denote the number of hole pixels with n, the naive solution will be O(n^2), since for each hole pixel, we sum over all boundary pixels (and the upper bound for the amount of boundary pixels is 4n, of course).

I was told a solution could be achieved in O(nlogn), but I couldn’t think of anything even close to that.

I thought of doing some bitwise operations, but I reached a dead end. I also tried reusing computations, but I couldn’t find any.

Moreover, the way I see it, there’s no avoiding calculating w(u,v) for the n^2 pairs of hole/boundary pixels – which is already more than O(nlogn).

What am I missing? Could you point me at the right direction?

Thanks

## theming – How to get BOOLEAN value of a Media Image in node.html.twig?

I was able to get the URL of the verctor_graphics reference media field with the following code:

But how can I get the boolean media field value (machine name: is_animated)?
