Talk:Comparison of graphics file formats

Transparencity

In my humble opinion, it is quite useful to add if all these formats can support transparencity (like ICO, TGA...). Is it a good idea? --MainMa 15:27, 17 July 2006 (UTC)[reply]

TGA Patented?

I'm fairly certain, though not absolutely, that TGA isn't a patented format. It can be either uncompressed or compressed using RLE.--Frankjr1284 18:16, 20 June 2006 (UTC)[reply]

Other Formats

DjVu. DjVu has DjVuPhoto.

MIME Types

I vote against including MIME types in the comparison. They're also in Graphics file format summary and cause problems there because of not being standarized. -- Peter 19:57, 12 January 2006 (UTC)[reply]

64- and 128-bit color

Can someone please verify the existence of 64- and 128-bit color? I don't think they exist. Most formats that support 48-bit color (16 bits per channel), only support 8 bits for alpha blending (for a total of 56 bits per pixel). Similarly, if a format supported 32 bits per channel, the result would be 96-bit color; with an 8-bit alpha channel, the result would be 104 total bits per pixel.—Kbolino 19:54, 11 June 2006 (UTC)[reply]

Answered my own question. The PNG standard specifies that the alpha channel must be as wide as the color channels.—Kbolino 20:08, 11 June 2006 (UTC)[reply]

SVG vector/raster

I do believe (and, as anyone can see above, my beliefs have a degree of inaccuracy) that SVG is a vector format. It cannot be exclusively raster, and as far as I know, it cannot embed raster images (only link to them). So, it is therefore an exclusively vector format.—Kbolino 21:31, 15 June 2006 (UTC)[reply]
