Dynamically resize an image depending on it's parsed dimensions

[OxygenCobalt]

I use coil for image loading a bitmap and putting it on my app's widget. Since I must always be mindful of how big my bitmap is (ill break the size limit otherwise), I have to dynamically resize it to fit under android's expected limit.

I've run into an issue doing this: Since some of my images can be non-square, I can't simply resize down every image to a fuzzy estimate of the bitmap size limit, since the longer images will always take up more space and will probably breach the limit.

I need some way I can take the dimensions of an image as soon as they are parsed, and then re-map the dimensions the actual size they should be decoded as on the fly.

Is there any way to do this in coil save simply a Transformation? I'm hesitant to implement a Transformation given that I would need to fully copy and resize the bitmap, which seems highly inefficient.

There's no way to intercept and resize an image loaded from a URL before it's disk cached, however ImageRequest.Builder.size lets you control how large it is when decoded as a bitmap.
