working with opacity?

[Avalin]

I love this app, it is really ideal for pixel art but I miss some semi-transparancy for when making water tiles etc., any support for this at all? It seems I can only make fully transparent or nontransparent pixels, nothing in between :c

Hi!

There is an opacity setting which can be set at layer level, but transparent colors are not supported.

See

I thought we already had an issue tracking a full support of transparency, but I probably closed it some times ago.

@juliandescottes Great tutorial! appreciated

The big problem is that when you open a sprite with transparency in it Piskel completely screws it up (not sure if this is a separate issue or not but it seems to go with this one).

That explains a lot about why importing certain sprites with others has really not gone well unless they were the same size or smaller than the current sprite. I never realized, but that seems to be the pattern.

I've spent a good few hours using piskel and putting all my faith in the layer-based opacity, but it all exported as fully opaque when I tried to export to png.

Is there any other way to export properly with the alpha channel or is the opacity setting only for editing and not exporting?

Took me a while to understand what you meant, very sorry about that. I guess what you're saying is that you're trying to have a PNG that is partially transparent, which you can then place over another image or background and the transparency would be preserved. Unfortunately, there is no such way; Piskel's transparency tools are primarily for blending, like making a slightly gradient edge between two solid colored regions. The partially transparent layer inserted between the two would achieve this effect. Piskel is not currently designed to preserve transparency against the image's background. It's a good feature to request, though. But keep in mind that the transparency functions don't have 100% preservation of the visual preview; it often looks quite different post-export.

Ah I see, thanks for clarifying. I'd really love to have transparency in PNG exports but looking at the creation date of this issue, doesn't look like it's coming anytime soon 😔.

We need transparency, but can we imagine a static image mode one day, rather than a systematic gif mode? Would managing the alpha channel of an image color on export be just as complex? How many of us export only a png rather than a gif?

I use it primarily for PNG and pixelart creation. Never exported a GIF.
But from time to time I do need some transparent pixels and doing them on a separate layer is a pain. So I vote for adding alpha channel to the colors.
