</div>Well now, I have fix all the issue with the alpha colorspace (I have added<br>
alpha darken). All it remains to do is to make mask support the indirect<br>
painting interface.<br></blockquote><div><br>Well, no. You've not fixed that. It's just a workaround.<br><br>Testcase:<br>1) Create any mask (e.g. transparency mask)<br>2) Paint something on a mask to get transparency<br>
<br>Let's imagine after these steps you decide to make some rect visible again, what are you going to do? In a good editor you just select this rect with selection and fill it with a white color (or any semi-transparent one(!)). You CAN'T do the same with krita, as far as i can see. Yes, you can use pixel eraser tool (that is not so obvious, btw), but what if your rect is 1024x1024 size? Are you gonna fill it with a small brush?<br>
<br>That's why i repeat again, we must use grayscale-like system for transparency masks. Current discreet selection system is a dirty hack.<br><br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
It doesn't use the gray color, but this is by design, it means you have to use<br>
the opacity setting (this is something we have been debating in krita for<br>
years, wether opacity belongs in the tool or in the color selector).<br>
Gradient work if you choose a gradient with transparency, in a future release,<br>
it could be worth investigating adding an option to the gradient tool for<br>
working on the transparent channel instead of colors (I think it might have a<br>
broader use).<br>
</blockquote></div><br>Do not create additional abstraction for a user. He knows what the color is, this is RGB values. The user DOES NOT know anything about our INTERNAL representation of the color as rgbA. RGB != RGBA. He knows (or should know) _nothing_ about alpha channel of the brush or of the layer. It's editor's job to think about alpha, not user's one!<br>
<br><br>PS:<br>Sorry for brute words. I don't know how to explain it. I repeat it again and again... <br>We have a weird selections system and you don't even want to make it better. <br><br clear="all"><br>-- <br>
