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.
