For this, (if I remember correctly), version 1.1 of the SHAPE extension adds a new kind of shape: In addition to bounding and clip shape, there is also the input shape.</p> <p>Thus, you could do something like this:</p> <ul><li>Turn bspwm into a reparenting WM (I am assuming it is not yet one)</li><li>The frame window for reparenting has two childs: The actual window with the client content and another window with the border <i>that is above the content window</i></li><li>Draw an antialiased version of rounded corners to some pixmap with the RENDER extension</li><li>Any pixel with non-zero alpha is the shape of the window that things are reparented to</li><li>Draw an antialiased version of just the border to some pixmap with the RENDER extension</li><li>Any pixel with non-zero alpha in this pixmap is used for the bounding shape of the border window</li><li>Additionally, you actually draw this shape to the border window <i>while honoring alpha</i> (i.e. this is done through the SHAPE extension)</li></ul> <p>Thus, you end up with the parent window having a shape that includes anything where the window should be visible. The border window only touches pixels where the border is visible thanks to its shape. The anti-aliasing of the shape happens through the actual window content.</p> <p>Additionally, you could set the input shape of the window that things are reparented to. For example, anything with alpha less than 50% could be made click-through.</p> <p>I am not quite sure if the above answers your question. However, I am sure that this is way too complicated for anyone to actually want to do this. And of course, if no compositor is running, this fails, since then you cannot actually do any semi-transparency.</p> <p>Perhaps it is best not to do antialiased rounded corners. :-)</p> <p style="font-size:small;color:rgb(102,102,102)">—<br>You are receiving this because you authored the thread.<br>Reply to this email directly, <a href="https://github.com/Javyre/bspwm/commit/94ba788802ea1d5d0e4419f7b9a357574b1e1451#commitcomment-30542158" target="_blank">view it on GitHub</a>, or <a href="https://github.com/notifications/unsubscribe-auth/AP9cg57sLQ9sEEudVEcUaMxlsttACRGiks5ucKNbgaJpZM4Wq7IU" target="_blank">mute the thread</a>.<img src="https://github.com/notifications/beacon/AP9cg342s68r1FBHtVqnMmpvMvapqiE8ks5ucKNbgaJpZM4Wq7IU.gif" alt="" width="1" height="1"></p> </blockquote></div></div></div></div></div></div><br><div class="gmail_quote"><div dir="ltr">On Mon, Sep 17, 2018 at 12:25 PM Javier Pollak <<a href="mailto:javi.po.123@gmail.com">javi.po.123@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="auto">I see..<div dir="auto"><br></div><div dir="auto">So if I wanted to have proper rounded bounding and antialiased corners, I would have to apply the bounding through shape-ext. and then reclip it in the compositor?</div><div dir="auto"><br></div>Proper bounding: having the mouse hi er over rounded corners and behave as expected<br><br><div class="gmail_quote" dir="auto"><div dir="ltr">On Sun, Sep 16, 2018, 12:20 PM Uli Schlachter, <<a href="mailto:psychon@znc.in" target="_blank">psychon@znc.in</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi,<br> <br> On 14.09.2018 19:47, Javier Pollak wrote:<br> > Hi, I'm working on a patch for bspwm to add rounded corners to windows and<br> > their borders.<br> [...]<br> > Is there any way to remedy this?<br> > What I tried so far is to apply an additional mask to the window background<br> > itself since it allows for a mask of the same depth as the window.<br> > The problem with that solution is that it does not apply to the border...<br> <br> If the problem is X11 window borders, then the only solution is not to<br> use them, but to draw your own borders instead.<br> <br> In general, you can use alpha values through the RENDER extension for<br> anti-aliased edges, but only if a compositing manager is running since<br> the X11 server does not do any compositing for you.<br> <br> Cheers,<br> Uli<br> -- <br> 99 little bugs in the code<br> 99 little bugs in the code<br> Take one down, patch it around<br> 117 little bugs in the code<br> -- @irqed<br><br> </blockquote></div></div> </blockquote></div>
