Screenshot quality tip for 2.1
As you've probably noticed, I like to do many of my own screen shots to accompany stories. Up until now, WoW has saved all screen shots taken in the program in a .tga format that has rich deep color and good definition. The only problem with that was that the .tga format was problematic for those who didn't have an image editing program to open their screen shots up with. (I have Photoshop, so not as much an issue here.) With 2.1 came a long-awaited change for those who weren't able to share their screen shots before (Or weren't interested in snagging a graphic program to do so, anyway). As of now, your screen shots will automatically save into .jpg format. Why is this a change I'd want to change back, you say? While I like .jpg for compression, I will be the first to admit it's not the format I normally think of as being the best for graphic quality as someone who works with images a lot. That said, for all of you graphic fiends out there like me -- makers of icons, wallpapers, and various other graphic goodies -- here is an important imaging tip for you from your friends at the EU WoW Forums:
As of 2.1.0 WoW will now automatically save your screen shots as .jpg, i.e. JPG format. This will cut down size immensely, but it will also cut out some details due to JPG being a lossy format. I've heard a lot of people requesting if it's possible to change the format which screen shots are saved in, for those people who want to change the format back to TGA you'll have to do the following (when 2.1.0 is out)
/console screenshotFormat tga
/console screenshotQuality 10
You can also look for the 2 lines in config.wtf:
SET screenshotFormat
SET screenshotQuality
Change them to what you want and start the game.
Both commands are important, the screenshotQuality is set to 3, which makes it look like a JPG, but in TGA format.
So this concludes my guide on how to change to TGA when 2.1.0 hits, and if you want it back to normal you can use these commands:
/console screenshotFormat jpg
/console screenshotQuality 3
Optionally you could could create an add-on utilizing this, using SetCVar ( http://www.wowwiki.com/API_SetCVar

Yeah it's too bad it's in JPG. I'd have preferred PNG. Just as small, but higher quality? I read that thread, and apparently you can only do PNG on Mac copies of WoW? Not cool.

I use IrfanView. Free, light on resources, and can open just about anything. It has some limited image manipulating features but has what's needed: image cropping and resizing. Also, batch operations ftw.

...and be sure to grab the plugin pack.

As did I. For a long time I've used UICentral's Screenshot converter to convert them to JPG for simplicity's sake.
Addie May 23rd 2007 3:42PM
I'm guessing you can keep the jpg format and up the quality to 10? Hrmm - gonna experiment from home. I do take gobs of screenshots.

Can you set jpg quality to 10 and get a low compression jpg?
Chris Anthony May 23rd 2007 3:58PM
I did some rudimentary testing this afternoon, and you'd have to be really picky to see any significant difference between the JPG output at quality 10 and the TGA output at quality 10. Unless you're going to be blowing screenshots up to 500% or more, you can probably leave it as JPG but set the quality to 10; you'll get about a 50% size reduction for about the same quality.

The Gimp is great for converting from tga to whatever, and it's free. It's basically an open-source Photoshop clone.
Also, I sent in my ReaderUI, when will I expect some feeback?

a thing to know
in tga or png (I've a mac) the wow client will freeze a little time longer (2 second for me) to create the picture file, the file is bigger than in jpeg quality 3.

"due to JPG being a lossy format"
jpeg is not lossy, its some kind of hybrid
metacarpal May 23rd 2007 7:44PM
JPG is definitely a lossy compression method.
Is it intentionally ironic that this post's graphic is a dithered GIF?
haust May 23rd 2007 7:17PM
jpeg is not lossy ?? Hybrid, you say. Yeah, lossy hybrid then....
(Ok jpeg can support non lossy encoding but I doubt apps use it)
Merus May 23rd 2007 7:58PM
Hybrid? Between what, lossy and non-lossy?
Tuberon May 23rd 2007 11:04PM
the JPEG standard does include non-lossy variants, but they are rarely used.
TGA, while not forcibly lossless, is often used with RLE lossless compression. Warcraft has used it this way.
JPEG quality 10 would be a very low compressed (but not bit perfect) image, and in most circumstances, would be acceptable, but there would likely still be compression artifacts.
For those wishing to maximize quality while minimizing file size, you may want to look into alternative solutions such as Fraps or SnagIt type programs, which are able to save the images as PNG.
While using third party software is never the most optimal solution, until Blizzard offers more choice in screen shot file types, it is a viable and reasonable suggestion to consider.

I was unaware of the screenshot change. I use(d) XnView to do bulk/batch image conversions from TGA to JPG. I used to use Irfan (like a previous poster mentioned) but the image browser in XnView blows it out of the water and once you figure out how everything works, it's 10x the program. Using photoshop to convert screenshots is MASOCHISM!
Swiftlydead May 24th 2007 12:57PM
jpeg quality is adjustable. You can make a jpeg that's 1/10th the size that you can not discern any quality loss from the TGA. TGA is uncompressed, oversized garbage!! Completely unnecessary.
