Dilate & Erode morphology

[masotrix]

Question about an existing feature

What are you trying to achieve?

I am trying to dilate a black signature in a white transparent image after resizing it because it seems much thinner after the transformation

When you searched for similar issues, what did you find that might be related?

I found an old issue #1719 that seems to be not resolved, but would like to know if there is a workaround

Please provide a minimal, standalone code sample, without other dependencies, that demonstrates this question

// current
const scaledImg = await sharp(imBuffer).resize(130, 90);

// desired
const scaledImg = await sharp(imBuffer).resize(130, 90).dilate(1);

Please provide sample image(s) that help explain this question

Here is the original version of the signature

And here is the scaled version, which we would like to dilate to make it thicker

Let's continue to track this at the existing, future possible enhancement at #1719
