Making a crowdsourced project on Canvas - page 44

Реter Konow:
Yes, Nicholas is a master in the art of working with canvas. It's an art of its own. For data visualization, interface decoration and control shell design these skills are irreplaceable. Digital artist. (No kidding).

I should add that Nikolai not only has an excellent understanding of drawing algorithms, but also knows which formulas to use for smoothing shapes, diffusing shadows and colour shimmers. Not everyone can do that.

That's the reason I asked Nikolay! And I'm grateful to him that he can still find a few precious hours to make an example of rounded primitives. This is a very valuable example!

Алексей Барбашин:

Dimitri, can you show me an example?

The code or just what it looks like?

Dmitry Fedoseev:

Both, of course. After all, we only go into the code when we become interested in the picture itself :)

I certainly don't have the code. And with an example, it's hard to make it clear. Below are two images. The shadow is grey, on the left it is normal overlay, on the right it is multiplication. On the right it is coloured and matches the background colour, as if transparent.

You can't see it in this picture, but I see what you mean. Yeah, you're right. I set the shadow settings wrong. I had colour for shadow 0xFF303030 - gray opaque with blurred edges, and I need black transparent with blurred edges 0xCF000000.

When I get to the computer I will post pictures with the new settings.

Nikolai, I suggest you also post the corrected example in your"Canvas is cool!". I'm sure there are people watching your thread and they will be very interested in the new example!

Yes, the dsp version.
