Subject: image descriptors and defimage with :data
Date: 08 Feb 2002 03:50:53 +0000 [thread overview]
Message-ID: <87zo2kaaxu.fsf@tf1.tapsellferrier.co.uk> (raw)
I'm building an image from a part returned by an IMAP server.
Instead of saving the part to a file and opening it that way I
thought it would be fun to have no file caching and just open the
image directly from the imap server.
My code gets the part from the imap server as a string and then
constructs an image descriptor for it.
It then uses insert-image to get it into a buffer.
But the image doesn't get displayed.
Emacs 21 manual says that defimage must have at least the following
properties in the props list:
:type
:file
But I don't want to specify the image as a file. Can (defimage ...)
cope with something like the following?
(defimage content-image
((:type jpeg :data content)))
