/* JPEG loading and saving file filter for the GIMP
* -Peter Mattis
*
* This filter is heavily based upon the "example.c" file in libjpeg.
* In fact most of the loading and saving code was simply cut-and-pasted
* from that file. The filter, therefore, also uses libjpeg.
*/
/* 11-JAN-99 - Added support for JPEG comments and Progressive saves.
* -pete whiting <pwhiting@sprint.net>
*
* Comments of size up to 32k can be stored in the header of jpeg
* files. (They are not compressed.) The JPEG specs and libraries
* support the storing of multiple comments. The behavior of this
* code is to merge all comments in a loading image into a single
* comment (putting \n between each) and attach that string as a
* parasite - gimp-comment - to the image. When saving, the image is
* checked to see if it has the gimp-comment parasite - if so, that is
* used as the default comment in the save dialog. Further, the other
* jpeg parameters (quaility, smoothing, compression and progressive)
* are attached to the image as a parasite. This allows the
* parameters to remain consistent between saves. I was not able to
* figure out how to determine the quaility, smoothing or compression
* values of an image as it is being loaded, but the code is there to
* support it if anyone knows how. Progressive mode is a method of
* saving the image such that as a browser (or other app supporting
* progressive loads - gimp doesn't) loads the image it first gets a
* low res version displayed and then the image is progressively
* enhanced until you get the final version. It doesn't add any size
* to the image (actually it often results in smaller file size) - the
* only draw backs are that progressive jpegs are not supported by some
* older viewers/browsers, and some might find it annoying.
*/
/*
* 21-AUG-99 - Added support for JPEG previews, subsampling,
* non-baseline JPEGs, restart markers and DCT method choice
* - Steinar H. Gunderson <sgunderson@bigfoot.com>
*
* A small preview appears and changes according to the changes to the
* compression options. The image itself works as a much bigger preview.
* For slower machines, the save operation (not the load operation) is
* done in the background, with a standard GTK+ idle loop, which turned
* out to be the most portable way. Win32 porters shouldn't have much
* difficulty porting my changes (at least I hope so...).
*
* Subsampling is a pretty obscure feature, but I thought it might be nice
* to have it in anyway, for people to play with :-) Does anybody have
* any better suggestions than the ones I've put in the menu? (See wizard.doc
* from the libjpeg distribution for a tiny bit of information on subsampling.)
*
* A baseline JPEG is often larger and/or of worse quality than a non-baseline
* one (especially at low quality settings), but all decoders are guaranteed
* to read baseline JPEGs (I think). Not all will read a non-baseline one.
*
* Restart markers are useful if you are transmitting the image over an
* unreliable network. If a file gets corrupted, it will only be corrupted
* up to the next restart marker. Of course, if there are no restart markers,
* the rest of the image will be corrupted. Restart markers take up extra
* space. The libjpeg developers recommend a restart every 1 row for
* transmitting images over unreliable networks, such as Usenet.
*
* The DCT method is said by the libjpeg docs to _only_ influence quality vs.
* speed, and nothing else. However, I've found that there _are_ size
* differences. Fast integer, on the other hand, is faster than integer,
* which in turn is faster than FP. According to the libjpeg docs (and I
* believe it's true), FP has only a theoretical advantage in quality, and
* will be slower than the two other methods, unless you're blessed with
* very a fast FPU. (In addition, images might not be identical on
* different types of FP hardware.)
*
* ...and thus ends my additions to the JPEG plug-in. I hope. *sigh* :-)
*/
/*
* 21-AUG-99 - Bunch O' Fixes.
* - Adam D. Moss <adam@gimp.org>
*
* We now correctly create an alpha-padded layer for our preview --
* having a non-background non-alpha layer is a no-no in GIMP.
*
* I've also tweaked the GIMP undo API a little and changed the JPEG
* plugin to use gimp_image_{freeze,thaw}_undo so that it doesn't store
* up a whole load of superfluous tile data every time the preview is
* changed.
