comment How to optimize images to improve pagespeeds / webpage loading times?
This "answer" is just a copy-paste from the linked page, which itself smells vaguely spammy. Without the copy-pasted text and image, it would be a link-only answer. I'm not flagging this as spam, since the author seems to be an established user and probably deserves the benefit of the doubt, but I'm definitely giving this a -1.

comment Can I reduce the file size of an SVG to be closer to its JPEG equivalent?
Look closely at the controller: if you select "Remove raster images" when optimizing the original SVG, the shading on the controller disappears completely (because it's actually an embedded semitransparent PNG). You can actually see it if you compare the screenshot in your answer to the original JPEG. The 4.02 kB version I got is bigger because it includes an extra path and gradient to replace the removed shading.

As with SVGOMG (from Dom's answer), here also the biggest savings seem to come from disabling xlink, which, as a side effect, completely deletes the embedded image. Obviously, replacing the image with a gradient isn't really something you can expect an automated tool to do.

comment Can I reduce the file size of an SVG to be closer to its JPEG equivalent?
I don't have the un-optimized version with just the gradient fixed any more, but if I manually edit the original SVG to replace the bitmap with the last <radialGradient> and <path> from my hand-optimized code, SVGOMG optimizes the resulting 5.8 kB image down to 4.02 kB (4.11 kB prettified), and seems to do a pretty thorough job; I don't really see any obvious missed opportunities. (Playing with it a bit more, I did notice that it sometimes fails to merge consecutive groups with identical attrs; Inkscape sometimes seems to generate those, e.g. when adjusting the page to fit the drawing.)

Looking at the rendered preview, it seems that most of the savings come from the fact that it completely deletes the embedded image. Obviously, replacing the bitmap with a gradient isn't something one can expect a software tool to do automatically.

+1 That's awesome! Honestly, I wasn't even aware that this tool existed. With the right options, the command-line version even beats my hand-optimized code by almost 200 bytes, and running it on the hand-optimized code gets it down to just 4571 bytes(!).

If you have a good enough display and eyesight, once.

comment Is there a name for a Wikipedia-like “W”?
You may already know this, but just for completeness, let me note that the specific font originally used in the Wikipedia logo was Hoefler Text, although it was later changed to Linux Libertine, with a special variant glyph for the W.

comment How to make PNG-quality animations in GIF format?
Also note that a 30 fps frame rate is high enough that at least some versions of IE will not run that animation at its intended speed. It may not matter much in this case, but if you need to ensure a consistent animation speed between browsers, the highest safe frame rate appears to be 16.67 fps (= 60 ms frame delay).

comment How to make PNG-quality animations in GIF format?
One more detail to note is that each frame in a GIF animation can have it own separate 256-color palette. One way to make use of that feature is that, if the color scheme in your animation changes halfway through, like in the example animation linked above, you could prepare the segments of the animation separately and then join them together using a GIF processor like GIFsicle.

comment BW image - make all black areas blue?
That does seem like a good reason, and may even legally qualify as a valid signature. (I'm not a lawyer, but AFAIK, the law in most places tends to follow the principle that if you call something your signature, it is your signature.) Still, my warning stands: if the place you're sending this to is nitpicky enough to have already rejected one form for an "invalid signature", there's no guarantee that they'll accept a re-colored one either. A printed picture of a signature just won't look quite the same as a handwritten one, at least not unless you use a really high-quality printer.

comment BW image - make all black areas blue?
@user23122: Why not just sign the form by hand? Or are you trying to forge someone else's signature? If so, please do note that a) this is dishonest, and possibly illegal, and b) no matter what you do, the recipient can probably tell a printed signature from a handwritten one, if they look closely.

comment Problems with Inkscape's trace bitmap when converting with multiple colors
@DA01: The tracer, in effect, quantizes the colors anyway -- it's not smart enough to extract additional contour information from anti-aliasing. You can sometimes recover some of the lost detail by scaling up your image (say, by a factor of 2 or 3) before quantizing it (and perhaps using a small amount of Unsharp Mask to sharpen the edges blurred by the scaling). In any case, however, you'll most likely need to tweak some of the edge pixels by hand in your raster editor (PS / GIMP / etc.), as there will likely still be some stray pixels of intermediate colors along edges that should be sharp.

comment Winter Bash 2014 Graphic Design
The snow animation used on the Winter Bash home page is actually a rather fancy custom-written one by balpha; see meta.stackexchange.com/questions/213043/… and blog.stackoverflow.com/2014/12/winter-bash-2014. Relevant quote from the 2014 blog post: "Management gave us a clear mandate when it came to building new features into Winter Bash: We were not allowed to spend weeks on snow animation."

comment Making backgrounds of animated GIF files transparent
Hmm... have you tried using the command prompt and specifying the full path to the gifsicle.exe? Or cd-ing to the folder you installed gifsicle into, and running the command from there? Or adding that folder into your %PATH%?

comment Why do two perfectly adjacent rectangles create black or white lines in between as if they were overlapping or not exactly adjacent?
@Lilienthal: I've never seen it; then again, the whole point is that you're not supposed to see it. I suppose one reason why the need rarely arises in practice is that most designers tend to avoid putting such strongly contrasting pure colors next to each other anyway.

comment Add transparency to an existing PNG
@Boris_yo: It's hard to tell why that might be, without seeing the actual pictures, but the techniques from this answer might help. Of course, you'd have to adapt them to Paint.NET yourself.
