Stage question

[ghost]

this project's stage is 640 x 360 preserve aspect ratio when resized and I want it to run in maximized window

How to remove these black lines? I don't want to use Stretch stage to fill screen without changing actual size and
Dynamically resize size to match because it changes sprite sizes.

Is there any solution?

Not really much you can do about that if you're not willing to accept stretching or dynamic stage size changes...

640x360 would likely perfectly fill up a fullscreen window on your computer but maximize has the window title bar and the windows task bar which take space away making it not fill completely.

so what about html? it will be the same
also maybe there's special stage size that will fill bars... maybe 1920 x 1080?

Whatever environment you use does not change the reality of the math. You probably have a 1920x1080 screen so 640x360 would fit exactly perfectly if your window was fullscreened (this is different from maximizing).

However when maximized you have the Windows task bar and window title bar taking vertical space away, so the window has to compensate by having black bars on the side.

You could try to find a slightly shorter aspect ratio that fits exactly when compensating for the window title and task bar. However this won't work for anyone using slightly different Windows settings causing anything to be even a single pixel different in size. Your game would also then have black bars on the top and bottom if you were to fullscreen it.
