Yes, this is how image-dired-thumbnail-mode works. It comes to
bookkeeping original file metadata which could be done in the image data
structure itself.
The transform api and manipulation UI is almost finished. I will post it
later today. What I am doing right now is converting the image to
imagemagick type whenever user requests a transformation of any
sort. This works very well with the drawback that the image is loaded
twice once as original type and then as imagemagick. I don't feel any
difference in speed of conversion though.
To avoid this, I have create-image-prefer-type which can take
'imagemagick or nil. In the future it can be extended to other
back-ends, if any. This variable takes effect only when create-image is
called with no explicit TYPE argument. Is this a right approach?
