[edit] Conversion page

Any chance of a summary of how to convert from one format to another using netpbm, imagemagick, pngtools and other command line programs?

[edit] Other Formats

Great page. How about .pcx? olivier 11:16, Dec 16, 2003 (UTC)

I've added it. Romanito 10:51, 29 May 2006 (UTC)

[edit] Debian MIME types

Very useful.

FWIW, my system (Debian) has the following MIME types, which are missing or different from those listed:

  • PBM: image/x-portable-bitmap
  • PGM: image/x-portable-graymap
  • PPM: image/x-portable-pixmap
  • ART: image/x-jg (for Johnson-Grace, I bet)
  • CPT: image/x-corelphotopaint
  • XCF: application/x-xcf
  • EPS: application/postscript (same as PS)
  • AI: application/postscript (same as PS)
  • BMP: image/x-ms-bmp (an obsolete MIME type?)

The last 3 are different from the table here. I don't know if these are more correct or less correct than the ones already here. Though image/x-ms-bmp sounds like an obsolete MIME type to me. Then again, this page says Windows bitmaps have no fewer than 12 MIME types. (Debian switched in January 2004 from image/bmp to image/x-ms-bmp consistency with Imagemagick, apparently. Don't you wish MIME types were canonical?) 4.16.250.42 02:10, March 1, 2005 (PST)

MIME types are defined by IANA, no room for error....--feline1 12:29, 8 January 2006 (UTC)
Sure mime types are supposed to be defined by the IANA but any new format will initally have to use an unregistered mime type (such names are supposed to begin with x- but that rule does get broken). Such names commonly remain in use for compatibility reasons even when a different official name is registered. Plugwash 17:01, 7 April 2006 (UTC)

[edit] Similar article and naming conventions

There's an article Image file formats that I think we merge and/or reorganize. Also, according to Wikipedia:Naming convention#Lists we should name the articles "List of… " something. The question is, is it graphics formats, or image formats? The Category:Graphics file formats already exists.

I believe the Image file formats article should be called Image file or Graphics file and talk about what an image is. Then, it should have a "see also" for the specifics to a List of image files, perphaps listing the most popular on the former, but still pointing to the latter. Also, this page needs a style cleanup.

So what do you think? —Fitch 19:33, 1 November 2005 (UTC)

I believe it should be something with "graphic", not with "image", since the word "image" is used in a wider context in computer science, for example as a "disc image". -- Peter 11:37, 8 January 2006 (UTC)
