+* README for the ImageMagick Emacs branch
+
+This is the imagemagick branch of Emacs. Imagemagick can now be used
+to load many new image formats, and also do useful transforms like
+scaling and rotation.
+
+This file will attempt to contain draft NEWS, Changelog and manual
+entries for the new functionality. 
+
+You might need to regenerate the configure scripts:
+aclocal
+automake
+autoheader
+autoconf
+./configure --with-imagemagick
+
+
+* TODO  image-type-header-regexps priorities the jpeg loader over the
+imagemagick one. This is not wrong, but how should a user go about
+prefering the imagemagick loader? The user might like zooming etc in
+jpegs. 
+
+try (setq image-type-header-regexps nil) for a quick hack to prefer
+imagemagick over the jpg loader.
+
+* TODO  For some reason its unbearably slow to look at a page in a large
+  image bundle using the :index feature. The imagemagick "display"
+  command is also a bit slow, but nowhere near as slow as the emacs
+  code. It seems imagemagick tries to unpack every page when loading
+  the bundle. This feature is not the primary usecase for the
+  imagemagick patch though.
+
+  ImageMagick 6.6.2-9 introduced a bugfix for single page djvu load.
+  It is now way faster to use the :index feature, but its still not
+  very fast.
+
+** DONE optimize number of pages calculation for bundles as suggested by
+  imagemagick forum: "set the density to something low like 2 and use
+  MagickPingImage()"
+  
+** TODO try to cache the num pages calculation. it can take a while to
+  calculate the number of pages, and if you need to do it for each
+  page view, page-flipping becomes uselessly slow.
+
+* TODO integrate with image-dired
+
+* TODO integrate with docview. 
+  
+* TODO integrate with image-mode
+Some work has been done, M-x image-transform-fit-to-height will fit
+the image to the height of the Emacs window for instance.
+
+* TODO look for optimizations for handling images with low depth
+Currently the code seems to default to 24 bit RGB which is costly for
+images with lower bit depth.
+
+* TODO complete documentation drafts below
+
+* DONE fix inconsistencys with spelling of imagemagick in the src
+* DONE report number of images in image bundle types somehow
+Works like for "gif" support. Thanks to Juri Linkov.
+* DONE probably add pdf to inhibited types
+* DONE inhibit types is defconst should probably be defcustom
+* TODO decide what to do with some uncommitted imagemagick support
+  functions for image size etc.
+* TODO Test with more systems
+Tested on Fedora 12, Fedora 14 so far, and the libmagick that ships with it.
+Ubuntu 8.04 was also tested, but it seems it ships a broken
+ImageMagick.
+
+I also tried using an imagemagick compiled from their SVN, in
+parallell with the one packaged by Fedora, it worked well.
+
+* DONE Also need some way to handle render methods that only work on newer ImageMagicks
+Is handled by configure now
+
+* Some nits from Stefan Monnier
+I just took a quick look at the code and I see the following nits to fix:
+
+** DONE obviously a merge will have to come with a good ChangeLog.
+** DONE also the merge will need to come with documentation.  Maybe not in the
+   Texinfo form yet, but at least in the etc/NEWS with enough info that
+   describes the `scale' and other such arguments that someone can start
+   using them.
+** DONE the README talks about naming inconsistencies, I think these should be
+  fixed before a first commit (should be straightforward).
+
+** DONE the "let" in image.el should not be followed by a line break and the while
+   should be replaced by a dolist.
+
+** DONE the prototype of imagemagick_load_image has some odd indentation in ([[2010.06.14]])
+   its args, not sure what happened.
+** DONE a few lines in the C code break the 80columns limit.
+** DONE please use ANSI style function declarations rather than K&R for new code. ([[2010.06.14]])
+** DONE you can get rid of the prototypes by reordering the code. ([[2010.06.14]])
+** DONE the docstrings in DEFUN should not be indented (they'll display ([[2010.06.14]])
+   weirdly otherwise in C-h f).
+** DONE Some "{" are at the end of a for/if rather than on their own line. ([[2010.06.14]])
+** DONE why use "*( imtypes + i)" rather than "imtypes[i]"? ([[2010.06.14]])
+** DONE some "," lack a space after them. ([[2010.06.14]])
+** DONE several "=" and "==" lack spaces around them. ([[2010.06.14]])
+  
+
+* NEWS entry
+** ImageMagick support
+It is now possible to use the Imagemagick library to load many new
+image formats in Emacs.
+
+To enable, use the following configure option:
+--with-imagemagick
+
+The new function (imagemagick-types) returns a list of image file
+extensions that your installation of imagemagick supports.
+
+The function (imagemagick-register-types) will enable the imagemagick
+support for the extensions in imagemagick-types minus the types listed
+in imagemagick-types-inhibit.
+
+imagemagick-types-inhibit has the value  '(C HTML HTM TXT PDF) by default.
+This means imagemagick will be used also to load jpeg files, if you
+have both jpeg and imagemagick libraries linked. Add 'JPG to
+imagemagick-types-inhibit if you do not want this.
+
+imagemagick-render-type is a new variable which can be set to choose
+between screen render methods.
+
+- 0 is a conservative metod which works with older ImageMagick
+  versions. It is a bit slow, but robust.
+
+- 1 utilizes a newer ImageMagick method   
+
+
+Images loaded with imagemagick will support a couple of new display
+specification behaviours:
+
+- if the :width and :height keywords are specified, these values are
+used for scaling the image. If only one of :width or :height is
+specified, the other one will be calculated so as to preserve the
+aspect ratio.If both :width and :height are specified, aspect ratio
+will not be preserved.
+
+- :rotation specifies a rotation angle in degrees.
+
+- :index specifies which image inside an image bundle file format, such
+as TIFF or DJVM, to view.
+
+The image-metadata function can be used to retrieve the total number
+of images in an image bundle. This is simmilar to how GIF files work.
+
+* Manual entry
+nothing yet, but the NEWS entry could be adapted.

+The Imagemagick library can be used to load many image formats in Emacs.
+
+The function (imagemagick-types) returns a list of image file
+extensions that your installation of imagemagick supports.
+
+The function (imagemagick-register-types) will enable the imagemagick
+support for the extensions in imagemagick-types minus the types listed
+in imagemagick-types-inhibit.
+
+imagemagick-types-inhibit has the value '(C HTML HTM TXT PDF) by
+default.  There can be overlap between image loaders in your Emacs
+installation. If you never want to use the ImageMagick loader to use
+Jpeg files, for instance, add 'JPG to imagemagick-types-inhibit. Which
+loader that will be used in practice depends on the priority of the
+loaders.
+
+imagemagick-render-type is a new variable which can be set to choose
+between screen render methods for the ImageMagick loader.
+
+- 0 is a conservative metod which works with older ImageMagick
+  versions. It is a bit slow, but robust.
+
+- 1 utilizes a newer ImageMagick method   
+
+
+Images loaded with imagemagick will support a couple of new display
+specification behaviours:
+
+- if the :width and :height keywords are specified, these values are
+used for scaling the image. If only one of :width or :height is
+specified, the other one will be calculated so as to preserve the
+aspect ratio.If both :width and :height are specified, aspect ratio
+will not be preserved.
+
+- :rotation specifies a rotation angle in degrees.
+
+- :index specifies which image inside an image bundle file format, such
+as TIFF or DJVM, to view.
+
+The image-metadata function can be used to retrieve the total number
+of images in an image bundle. This is simmilar to how GIF files work.

+
+Until now, we have spoken about the system and the session buses,
+which are the default buses to be connected to.  However, it is
+possible to connect to any bus, from which the address is known.  This
+is a UNIX domain socket.  Everywhere, where a @var{bus} is mentioned
+as argument of a function (the symbol @code{:system} or the symbol
+@code{:session}), this address can be used instead.  The connection to
+this bus must be initialized first.
+
+@defun dbus-init-bus bus
+Establish the connection to D-Bus @var{bus}.
+
+@var{bus} can be either the symbol @code{:system} or the symbol
+@code{:session}, or it can be a string denoting the address of the
+corresponding bus.  For the system and session busses, this function
+is called when loading @file{dbus.el}, there is no need to call it
+again.
+
+Example: You open another session bus in a terminal window on your host:
+
+@example
+# eval `dbus-launch --auto-syntax`
+# echo $DBUS_SESSION_BUS_ADDRESS
+
+@print{} unix:abstract=/tmp/dbus-JoFtAVG92w,guid=2f320a1ebe50b7ef58e

+
+In Emacs, you can access to this bus via its address:

+   left to right, even for R2L lines.
+
+   Note one important detail mentioned above: that the bidi reordering
+   engine, driven by the iterator, produces characters in R2L rows
+   starting at the character that will be the rightmost on display.
+   As far as the iterator is concerned, the geometry of such rows is
+   still left to right, i.e. the iterator "thinks" the first character
+   is at the leftmost pixel position.  The iterator does not know that
+   PRODUCE_GLYPHS reverses the order of the glyphs that the iterator
+   delivers.  This is important when functions from the the move_it_*
+   family are used to get to certain screen position or to match
+   screen coordinates with buffer coordinates: these functions use the
+   iterator geometry, which is left to right even in R2L paragraphs.
+   This works well with most callers of move_it_*, because they need
+   to get to a specific column, and columns are still numbered in the
+   reading order, i.e. the rightmost character in a R2L paragraph is
+   still column zero.  But some callers do not get well with this; a
+   notable example is mouse clicks that need to find the character
+   that corresponds to certain pixel coordinates.  See
+   buffer_posn_from_coords in dispnew.c for how this is handled.  */
