Subject: Several suggestions for image support
Date: 16 Apr 2004 02:21:11 +0200 [thread overview]
Message-ID: <x5y8owu614.fsf@lola.goethe.zz> (raw)
PNG images support transparency. Emacs can't make use of it. You can
only have Emacs declare a particular color as transparent. This is
dissatisfactory. It should tell the PNG decoding routines Emacs'
background color for the purpose of transparency.
I would find it important if an image specifier could restrict the
displayed portion of an image.
The reason is that large images always appear as a single big
character to Emacs. If I could split such an image into a bunch of
smaller images, I could walk through it with the cursor. But it
should only be necessary to instantiate the complete image itself once
for this purpose. Of course, one should find a way that does not
cause all of the subimages to be entered separately into the image
cache.
