Brightness Control about openkneeboard HOT 13 CLOSED

Yeah, there's a few ways to do this:

• replace the background white for PDF/text pages. Doesn't work for images
• configurable transparency. Avoids the glare, but can be extremely low contrast for nighttime
• paint over with black at variable transparency. Ditto, but probably a bit better
• a negative filter: black <-> white
• a B&W 'brightness' filter with controllable intensity. Effectively night vision for the kneeboard

'brightness' filter might be the most realistic, and the best one-shot

'negative' would be clear, but possibly too intense

A combination is probably the way to go:

• paint over with black to reduce glare/god rays: this is effectively 'multiply brightness by x%')
• brightness filter -> night mode. Recolor in green and it's a true night mode. Black background, white/green text

I noticed the same in MSFS. I use a text-file tab for taking ATC notes and on a night flight the white background is really super bright. As a workaround I'd just hide the kneeboard as I'd only expect complex ATC instructions pre-takeoff and after landing (clearance and taxi mostly), so there's no real reason to show the kneeboard during the flight.
But still adjustable brightness would be cool. Of course the super bonus would be if cockpit lighting would affect the kneeboard, i.e. during the night you'd have to turn on your cockpit reading lights to see anything. But that might be a bit too much. :P

Would totally love to have the option of "NVG filter", it would make it consistent with the datacards I am generating for night missions (could share the C# code used for the filter if helpful, although I am a HW guy and the whole program is a mess from SW point of view)

Any chance your C# is a wrapper for HLSL? That would be handy - otherwise I can easily do a simple tint.

#84 is very related: while that's just dealing with opacity/transparency, the way it works is by applying a tint - but the tint includes an alpha channel - it's (1.0, 1.0, 1.0, 1.0) * opacity - where (1.0, 1.0, 1.0, 1.0) is RGBA white as floats.

Simple dimming can be done by using a grey tint instead of white, or red/green for colors.

I think the most practical is to create two functions: one to dim and one to add brightness, which then can be bound to a turning knob on the Hotas and be used the same way like the flashlight and NVG brightness controls in DCS. Adding color like red or green seems like a nice addition, but still can be way too bright if used independently without brightness control. Please look how the flashlight inside DCS works. It has a brightness function and a green/white toggle.

I have just checked. I am using a 3rd party (open source project): https://www.codeproject.com/Articles/5527/Blending-of-images-raster-operations-and-basic-col
I am using it to blend with an image of the green filter, with a gradient, as you can see above

If this feature request goes in (hopefully as a brightness filter), would be great to expose it through the remote-control exe methods. Would allow a quick VoiceAttack "Kneeboard Brighter" or "Kneeboard Dimmer" when a page is pulled up that isn't set for night.

Yeah, probably just going to do the 'make everything darker' approach.

After trying pen+paper with some high-end NVG, it seem likely that a 'realistic' NVG effect would be 'unreadable blurry mess' :p

Would y'all prefer this to only affect in-game rendering, or both in-game and in-app?

from openkneeboard.

In-Game would be enough for me :)

If I may add to that:
the app already uses the systems light/dark mode.
A setting for the ingame kneeboard with the same effect would be really cool!
Playing in HDR makes the kneeboard super bright^^

But I guess a filter would be even more usefull, if one has unchangeable PDFs and pictures, where there's a lot of white...
