True Rounded Corners

[mursman]

Rounded Corners Overlay (Screen-anchored)
Simpler alternative to per-window tracking: since a maximized window is always flush with its monitor's work area, this pins four small click-through, topmost, layered "corner mask" windows to the work-area corners of every monitor -- once, at startup, plus whenever display configuration changes (resolution, monitor added/removed, taskbar moved/resized).

Whatever window happens to be maximized underneath a corner automatically appears to have that corner clipped round. Works instantly for any app, any process, with no window enumeration loop at all.

Trade-off vs. per-window tracking: this only rounds corners that touch a monitor's work-area edge. A maximized window on a single monitor gets all four corners rounded (since it fills the whole work area). If you ever use a window that's large but not technically maximized, or an edge-snapped half-screen window, only the corners that land on the monitor's own corners will be rounded -- snapped windows won't get their inner corners touched by this mod, which is usually what you want anyway (only the screen-facing outer corners are visually squared off by DWM to begin with).

Same limitation as before on fill color: the corner cutout is a solid color, not a live capture of what's underneath. Tune fill_color to match your wallpaper/taskbar area.

Is there anything wrong with the procedure? The mod is working on my machine. Please tell me a bit in details, this my first time

[m417z]

The linked mod seems to be similar. My question is whether they're truly the same, or if your mod is different. There's no reason to have two mods doing the exact same thing.

[mursman]

After looking at its architecture and feature set, I'd say the #4636 implementation isn't primarily about rounded corners. Rounded corners are just one feature built on top of a much more general rendering framework.

Its real purpose is to provide a high-quality desktop overlay and composition engine.

[m417z]

Can you explain what your mod provides to users that #4636 doesn't? I didn't understand that from your messages, and you didn't post a screenshot.

So it seems that my understanding is correct and your mod doesn't add additional functionality compared to the other mod. I prefer not having multiple mods which achieve the same thing without a good reason.
