PrintScreen has dark gamma

[Kaz]

For some reason, screenshots taken with PrintScreen and then pasted into an image app have what appears to be .9 gamma. I've been using it to take screens of menus and whatnot, where /screenshot doesn't work.

I have an ATI Radeon 9200 se.

Any ideas?

Is this a problem? Use the image problem to correct the gamma to 1.1 or so.

[Kaz]

It's:

a) annoying
b) results in poorer quality screenshot

[AmIdYfReAk]

why wouldent you use the ingame Screenshot command?

[Kaz]

I've been using it to take screens of menus and whatnot, where /screenshot doesn't work.

[Kaz]

Nor does hitting the key it's binded to.

[raw]

The default screenshot key for Q3 is F11 which is a screenshot in .tga format. If you want it different, you can bind screenshotJPEG to a key or just run /screenshotJPEG.

[Kaz]

I'm not trying to be a dick, but please read what I'm saying.

I'm trying to take a screenshot of the main menu, or in-game menu that pops up when you hit esc. The /screenshot and /screenshotJPEG commands don't work with these menus, and therefore I have to use PrintScreen and then paste the image into an image editing app. My problem is that this image has darker gamma than what q3 is set at (1.0). I'd like to know if this is a known problem with my video card, or if there's something I can do about it.

[AmIdYfReAk]

heh, Quake 3 uses a renderng engine that adjusts the gamma though hardware instead of hardware, So you will get that no matter what unless you use the ingame, that is why i said that, as i am sure why raw said it as well..

you might need to resport to a program like Snag it or sumshit that might be able to Grab the picture out of the Vram.

Good luck.

Your drivers should have a gamma setting for 3D mode. If not, get decent drivers (Omega 3.8.231 or NGO drivers based on the 6.3 Catalyst drivers).

[CheapAlert]

odd, q3a should be able to take screenshots by bound key. i've took shots of the menu before

[Magnus]

Right. If you use "print screen" durring a running app or program like the Quake games it will end up with a darker or lighter render than what you took the shot of depending on system hardware.

While in the menus you use F12 to take a screenshot not F11. You will not see the text telling you that it took a screenshot, but if you bring down the consol after hitting F12 you will see something like Wrote screenshot/xxx.tga. :icon17:

[Kaz]

Thx for the help. I'll try some of that stuff :]

[raw]

I just tested and did an F12 at the main startup menu. Here's the screenshot it wrote (of course converted .tga to .png) and the condump.

Try it in Team Arena.

Try it in Team Arena.

Hmm? F12 nor F11 works in team arena. Odd I figured due to running on the same engine the functions would have been the same.

I'll look into why there is a difference and if there is a single key to take screenshots in Q3:TA.

But at least you can do menu screenshots in Q3A now....heh.
