The horror of horror application known as 'Microsoft Access' used to (I don't know if it still does as I shun it for the rabid cur it is) allow you to group radio buttons and consult their status and subscribe to their events at the group level - which is what I guess you have created.

Heck, I don't even care about events. I just want the FK ID for the selected item, or null if nothing was selected in the group. That's what I created, though I still need to see how Knockout does it, but since I prefer "model-less" web development (one day I'll write an article on that) I'd have to add a pseudo-model so Knockout has something to bind to.

So don't use them then. They're not supposed to be set programatically anyway. It's meant as a user selection device which means that you can pretty much do everything from the click event as any click automatically sets to checked.

 If I load existing selections, I damn well need to set the programmatically.

My goal is to get GIF files that can be handed over to a printer to print. Anyone who knows something about commercial printing is very welcome to reply! Now I am presuming that a commercial printer would be able to work with a GIF file, but if there is some other standard, I'm all ears.
I have a bunch of GIF files sized at about 10000 x 14000 that I used Paint.NET to produce from TIFF files (the GIFs are about 25M while the TIFFs are about 840M!) The original TIFF files were created by a scanner from thin, ink-printed plastic pieces, that had a few colors (i.e., like a cartoon). I haven't checked, but I presume that the although the original object was supposed to only have a few colors, that scanner picked up some slight variations of the few colors, and the GIF conversion process just fit whatever colors it detected into the 256-color map.
So I mainly want to get all the colors that are very close (i.e., all the colors that are really for the same original color) to get the same color, and to be mapped to color #1, #2, #3, etc. There is also some parts of these plastic pieces that are clear, so I figure that should be mapped to a color as well (color #0 maybe?) Now I know that the 32-bit BMP has an 8-bit part that signifies the level of transparency, but I am not sure how that would be done with a GIF. I can't seem to figure out how to do this in Paint.NET, but if it can be done, that would be great.
Thanks

While GIF doesn't support per-pixel alpha values, You can make palette entries entirely transparent or opaque, but it's only a 1bit flag - the pixel is there or it isn't. You should be able to make palette entries transparent with a menu option of some kind. Dunno, tried Paint.Net years ago and threw it out in preference of Gimp.
Also, for what it's worth, you'll get better compression with PNG, which uses the deflate compression scheme rather than the LZW one. As an example, the CP icon is a 4,795 byte gif. Converted to a png, its just 3,966 bytes. Depending on the material to be printed, you may also benefit from an image format that allows for colour-profiles to be embedded - important for accurate colour representation during print.
As for mapping the colours back to their original (desired) values, you may be able to posterize the image to the number of colours actually present. The final colour will be determined by the avg of the relevant pixels, so you should expect the colour to drift a little from the desired one. You can simply edit the palette after posterization such that it reflects the desired colours.

Use Paint.NET and save as PNG.
Select the 8-bit option when you are presented with a selection of bit depths for storing the image.

You could use IrfanView to convert the TIFFs. It's free, incredibly powerful, and has a batch mode. You should use PNG for your output files as has been stated. IrfanView has a 'Decrease Color Depth' command which will reduce the output size considerably.
What to do about the transparent areas is another matter, you'd have to do that part manually. PNG supports transparency.

I would strongly suggest using 8-bit PNGs rather than GIFs as PNGs have better compression.
For converting TIFFs to 8-bit PNGs (or GIFs) you can use GIMP with the Save for Web plugin. This plugin allows you to customize how the 24-bit image is converted to 8-bit indexed color in many ways, such as choosing the type of dithering, number of colors, etc. while giving a realtime view of the resulting image and its filesize.
GIMP also lets you posterize the image before exporting it, in which case you can set exactly which colors will be used.

Excellent: very entertaining.
What was better were the previews for Star Wars and Batman v Superman. BvS looks AWESOMESOMESOMESOME!!! Oh, and I have no idea why, but people cheered and clapped at the Star Wars trailer and even I had a wee tear in my eye when Harrison Ford turns to Chewie and says "We're home...". Or maybe it was "we're back...". Well, you get the idea...

In a way. He managed to convince the shark that he was not the seal it was looking for. Ask the shark which part of his behavior exactly made taking a test bite unnecessary.

First, you are swimming in the ocean, looking for today's meal. Then you see something that might be a tasty fat seal and get a little closer, just to be sure. And then the seal starts kicking, punching, screaming and polluting the water. What manners!

I've heard of stories where surfers punch a shark in the nose because that area is sensitive and throws them off. Kind of like a kick in the nuts.

Try to jump before a van coming down the road with 30 mph and stop it by giving it a good smack on the hood. That is about the mass and speed of an attacking white shark and the van does not even try to bite. The surfer only survived because the shark was still trying to figure out what he was. He would have had no chance to fight off a serious attack.

Yes you're correct - if the shark is attacking he's toast. Otherwise you have a chance.
