Any word on the transparency support? Potential updates?

well done!

2010-10-18T08:26:15.990-07:00

I'd like to see:
- support for XMP metadata
- psychovisual optimizations in the WebM encoder
- support for lossless encoding
- using both WebM inter and intra coding for images (as in the hipix image format)

Also, if you're adding alpha support to WebP anyway, alpha channel support in WebM (VP8 video) would be really nice.

2010-10-05T21:54:11.767-07:00

Should add XMP or EXIF support for image metadata. Easy enough for anyone to do, since you're using RIFF, but it should be standardized, and for now, you guys control the standard.

Well done

2010-10-05T13:14:46.512-07:00

If you are going to make a web specific image format, why not embed a metadata tag containing a URL to a better (resolute/quality) image. You could create multi-scale images as a chain of multiple files (whereby the lowest quality image is selected by default or if some CSS setting suggests it as default). Then the http client can recursively request better images in the background and refine the page dynamically. I'm sure that this is not a novel idea.

@Craig I'm afraid you're an immense jerkass-wad, and that you wouldn't be able to say what you said out face to face without a computer.
Newsflash: using 'newsflash' doesn't add any emphasis to your conclusion.

2010-10-01T11:55:50.509-07:00

Am I seeing that certain details actually seem to crisp-up in the WebP version? If so, then that kind of cool.

How is WebP with black & white?

I've got a site which is graphics-heavy with a stack of black and white .GIFs

Any chance it would be worth converting GIFs over to WebP?

Oh, and what kind of crunch power is required for this format? Is this going to drag on older machines?

2010-10-01T11:41:46.307-07:00

And why would JPEG "originals" show DCT artifacts that are not present in the WebP examples? Were they both compressed from a lossless original, or is there a mistake in your presentation of the examples?

Why do most of the WebP images show a significant ...

2010-10-01T11:37:40.499-07:00

Why do most of the WebP images show a significant color shift compared to the original images? Shouldn't that be considered a major bug?

sounds a lot like .art files to me.

2010-10-01T08:50:56.115-07:00

I'm interested to see this file format used and to see how it compares. Will it perserve transparencies? Is this supposed to be a replacement for all web images?

2010-10-01T08:11:23.457-07:00

Using scaled-down images for the sample gallery does not provide a useful comparison. If you want to limit the size of the web page, show crops from the full images, but show them at full scale.

A good idea, but practically, you're talking about a decade before the older browsers will have reduced by enough to enable this to be usable.

2010-10-01T02:08:25.090-07:00

Will it have a progressive mode? For small screens on mobile devices sometimes its enough not to have the full resolution. A mobile client could decide its got enough of a picture when a certain resolution is reached.

2010-10-01T01:18:56.739-07:00

It would be nice to compare the same image with different compression levels, in JPEG and WebP. I mean, same image at 100K, at 50K, at 25K.
Also do not use "Images in the left column are JPEG originals", use TIFF or PNG originals.

2010-09-30T23:16:06.523-07:00

I think will be a good idea to add a header with an index and embed several "versions" at different resolutions of the same image (with offsets and lengths).
So from a small device (smartphone) people could access to a small version of the image (without needing of downloading the whole file), and a normal computer could skip small versions and get the biggest resolution. That will greatly speed up internet navigation from mobile devices and will reduce traffic data.
