Also, I would greatly appreciate an option to disable the "wrote xxx.png" message.

And why does that bother you? 

speaking for myself:

When taking multiple screen shots in a row to perhaps catch a monster in a specific position, for example, you have to wait for that message to go away or to use host_timescale to slow down monsters.

When I have r_drawviewmodel 0 and crosshair 0 for screenshots, itd be nice to have some sort of way to avoid all on screen prompts and such. 

You can freeze monsters at will. Mark V has the freezeall command and other engines have sv_freezenonclients 1 

The large PNG's are intentional to try to limit hitching. They're compressed in the main thread of the engine, and default settings of png libraries I tried caused unacceptably long freezes in the game (like 0.5 seconds - 1 second depending on the resolution.)

If we moved the PNG compression to a background thread, we could use good but slow compression settings - this is just more work to set up.

Agree with a cvar for hiding the "wrote" message. 

Sometimes I like to take multiple shots at once, but then the best "takes" have the message printed on them which isn't too good aesthetically. 

There is a cvar called "con_notifytime" or similar which controls how long the console text appears at top of screen. Try setting it to zero, maybe even make a alias that sets it to zero before your screenshot and then back to default after? 

Thanks, metl. That works. Doesnt show on screen but still shows in the console so one can confirm screenshots have been taken. 

What mukor said. I've never seen a screenshot with the message showing. Maybe an older version of QS? 

examples of prompt displaying in screenshots 

One way of handling this is, rather than taking the screenshot immediately, just flag an "scr_screenshot" qboolean to true, then run SCR_UpdateScreen and if scr_screenshot is true selectively suppress certain UI elements. Finally glReadPixels and capture the screen. 

hmmm... 

yes, taking one screenshot wont display the message in the screenshot.

spam the screenshot key and youll get the message in the screenshot.

some people implement real world photography concepts into screenshots and one of those concepts is to take a quick series of images to then pull the best one from.

Think of skateboarding where they use shutter speeds to capture the whole trick then pick one of the pictures to use on the cover. 

heres a GIF with this in action:

yup, now I see it 

are these last few posts just one big troll?

you know the "clear" command is a thing yeah? clears the console?

bind F12 "screenshot;clear"

does what you want I think? 

metlslimes suggestion of "con_notifytime" is better than using clear, imo. 

reading that back again sounds a bit patronising, but I think it's a valid solution for now.

Maybe the fact it clears the console history doesn't make it a perfect solution. 

lol, I skimmed past that.

Yeah that's even better. 

yeah, i changed the binding now too.
no trolling intended. 

that rrp gif is 5 yrs old now, i just remembered making it was such a chore not knowing how to disable the message. 

It would be neat if QS allowed for changing the actual layout and functionality of the hud. I think stuff like that would be very cool esp for big mods like AD. 

That requires support for CSQC hud code - I think QSS has this supported, but I haven't had time to check it out yet. 

I always get warnings when I try to get QSS. 

the website? It's fine FYI.
