How to create floating viewport with specific size

[maxyweb]

(maxscript) how to create floating viewport with specific size like 800x600?

actionMan.executeAction -891545229 "0" creates window (maybe there is a more elegant way)
question - how to set window size?
Thanks!

(
	vp_id = #Floating_ViewPanel_1
	ViewPanelManager.SetFloatingViewPanelVisibility vp_id on

	w = windows.getchildhwnd 0 "Floating Viewport - 1"
	b = windows.getwindowpos w[1] removeUIScaling:on
	b.w = 800
	b.h = 600
	windows.setwindowpos w[1] b on applyUIScaling:on
)

It works very inaccurately. Instead of 800x600, I get 785x563 floating viewport, but I need the exact size

This happened because you asked the question "inaccurately". The floating viewport (window) is exactly 800x600. 

Now think how much you need to add to the window size to make its client area the size you need.

I don't understand what can be done here to get the exact viewport size of 800x600, besides, it most likely also depends on UIScaleFactor

You could try to create a window of size 815x637 to compensate for the extra space?

Or temporarily disable any UI scaling on the Windows OS level, just to make sure this does not interfere - and if that solves it, maybe we can use the UI scaling factor in getting the size right?

[maxyweb]

At a minimum, the height of the tittlebar depends on the UI scaling on the Windows OS level, 100% tittlebar=28, 125% tittlebar=31 etc

Provide a picture that illustrates the specific area you would like to have a certain size.

Do you need this size with or without the scaling factor?

(
	vp_id = #Floating_ViewPanel_1
	ViewPanelManager.SetFloatingViewPanelVisibility vp_id on

	w = windows.getchildhwnd 0 "Floating Viewport - 1"
	b = windows.getwindowpos w[1] removeUIScaling:on
	b.w = 800
	b.h = 600
	windows.setwindowpos w[1] b on ----- applyUIScaling:on --- don't use 
)

This makes the floating window exactly 800x600 pixels without any scaling factor.

By the way, why do you need the exact size for a floating window in the first place?

[maxyweb]

I don't know what I'm doing wrong, but I get 786x593, considering that system Windows scale is 100%.
I need to make a screenshot of 800x600 exactly using maxscript.

Windows scale can be from 100% to 200%

I can take a screenshot by changing the size of the main viewport, but its size does not always return to the original, I asked about this in the neighboring topics

This tool worked for me: https://www.brianapps.net/sizer4/

Open a floating viewport, then invoke the tool and set the window to 800x600 - a screenshot of the window was exactly that size.

[maxyweb]

This may be an interesting and practical solution, but it doesn't suit me, I need to take a screenshot using maxscript and it's a negligibly small part of the script. I have a working solution, but it's not smooth enough.

Simply grab a viewport using the built-in MAX methods and save the bitmap image at the resolution you want.
