Please pardon my ignorance: What is alpha channel and how would it be
useful or used?
Alpha defines whether a pixel in an image bitmap is transparent /
translucent or not, and if so, how much. PNG has 8 bit Alpha, e.g. 256
different transparency amounts. GIF has 1 bit Alpha, e.g. only yes,
transparent or no, opaque.
Gamma defines some kind of brightness, but is not equal to brightness.
There are common gamma values like 1.2 and 1.8.

Let's not forget a major disadvantage of PNG: it doesn't do anymation.
That's what MNG (Multi-image PNG) was made for, which is not widely
supported (Mozilla now does it, but I doubt many other browsers and much
other image manipulation software support it) yet though. There's also
JNG, by the way, which is kind of a PNG format with compression
techniques similar to JPEG. I think Mozilla now does that too.

hmmm. I though gif (Graphics Interchange File Format) was was an

How do you send a jpeg with enough detail that's File size is, not
overly large ? Seems you have two choices either enough detail to be
usuable, or small file size.

Because, as he pointed out, they do more file formats, they (well Snapz

Why _are_ there screen capture programs? Exactly because of this!

Hi,
when i need to make a screenshot, I am always unsure as to which
fileformat to save it to (gif, jpeg, png, etc.).
Since screenshots are usually only a few colors (no photos in the
shots), there must be some fileformat that keeps the filesize very small.
Also, what pixel size should I resize the file too (my monitor is at
1280x1024 - a bit high for most shots)? Currently, I usually resize to
640x480.
I would really appreciate any (detailed) suggestions. :)
BTW, this is only *semi* off topic, because I often need to post
screenshots to bugzilla. ;)
I use PNG. My preferred tool - on win32 - is HyperSnap DX, which has
both a lot of features and yet high performance. I mostly use either the
option Full Screen, Window, Button or Control or Region, so I can
crop away a lot of stuff which doesn't matter for the screenie - such as
the start button, which everybody knows what it looks like (ugly ;-) )
anyways. I save them in PNG, usually 24-bit, but sometimes also just
8-bit if it's too large of a screenshot and if there's not much
additional information given by a higher color depth (for example, for
black and white text display).
Mozilla has excellent PNG support (in contrast to IE 6 ;-) ), so that's
not the problem.
JPEG is pointless for most screenshots, unless you're doing screenshots
from a photoshop image.
GIF is less useful than PNG in case that PNG is supported by your
audience - in other cases, GIF might be sufficient (if not, you'll have
to use JPEG or something entirely different, such as those ugly huge
native bitmap formats).

.png isn't something new. If you are using a program that
doesn't support it then you shoud get a new version or

And if ALL you are talking about is Bugzilla, fine.
In general, tain't a very widely supported format.
If you take a screen capture and compress it to .jpg then
the final image will be different than the original, the

(and there are lots of lines in a screen capture) will have
noise, unless you compress the image so little that it

But Mozilla's news reader sucks eggs. And as most people have
the sense to post JPEGs, my current newsreader (a release a
month old) is perfectly adequate.
But for Bugzilla, fine.
