Bug ID: 319241
Summary: "Embedded preview loads full-sized image" button
Platform: Gentoo Packages
Assignee: digikam-devel at kde.org
Reporter: bugs at londonlight.org
Some files have embedded previews, some don't. Those formats that do, to the
best of my knowledge, are just raw and possibly TIFF.
I will not discuss TIFF images with embedded previews in this issue as I have
never encountered them or had a need for embedding a lower resolution preview
(other than a thumbnail) into a TIFF file.
As for raw files, I would like to be able to set digiKam to either show me a
fast preview of the real raw data, or to show me the largest embedded JPEG
(some raw files have more than one embedded JPEG size).
I envisage replacing the current ambiguous single button a single-option radio
button list such as this:
● real file contents
○ half-size real file contents
○ largest embedded image
Personally I see no use for option 2, but if a half-size image from the real
raw data really can be generated faster (4 times as fast?) then why not. But
digiKam 3.1.0 takes about as long to show me this half-size preview as
RawTherapee does to show me a full-sized one (subjectively, not timed
I believe such a single-option radio list would be entirely clear, unlike the
current single checkbox which not only does the opposite of what its label says
(the label is after all "Embedded preview loads full-sized image" which is the
opposite of what happens for raw files) but actually makes no sense - the
embedded preview is the embedded preview. How can an embedded preview load a
full-sized (or half-sized) image. It can't. It's an embedded preview. I
understand that by "embedded preview" you're not actually referring to the
embedded preview but to the button two frames above called "Thumbnail click
action" but this is a really poor way of doing it.
