[Digikam-devel] Experimental : image preview on main interface

[Gilles Caulier-2]

Hi all,

Following some reports from B.K.O and discussions by IRC/mails, some users
would to have a preview mode of current album item, directly in main
interface, without to start an instance of image editor. Image editor take a
while with old computer to just previewing a RAW picture.

I have search a simple solution to do it.... and this is my proposal :

http://digikam3rdparty.free.fr/Screenshots/image_preview_on_main_interface.png

I have make an experimental patch using QWidgetStack to embed into album
collection area a new image preview. You toogle between preview and album
view using F3.

The patch is here :

http://digikam3rdparty.free.fr/misc.tarballs/preview.patch

The RAW preview use the -e dcraw option to load the embedded JPEG image in RAW
file (used to display a RAW picture on TV screen)

This patch separate Preview mode (F3) and the Edit mode (F4) on Image menu
entries. If you enable the ImageProperties sidebar, use the navigate button
to change the current image to preview.

This code is simple and not finalized. For example the code :

- don't use a cache to speed up rendering.
- don't use the embedded preview from JPEG/TIFF/PNG files available in
Makernote metadata. Canon, Nikon, Minolta, etc, record a small preview image
in Camera Settings. This is must be used instead to load the whole image. In
fact, Exiv2 need to be improved for that. i'm currently working with Andreas
about this subject.
- use QImage, not Dimg.
- don't load the preview using a separate thread to unfreeze ther GUI (Image
Editor do it). We can use a new KIO slave for that but not sure (Marcel, your
viewpoint ?)

Please don't ask me to create a very advanced new feature for 0.9.0. I have
not commited this code in svn because i'm not sure if this is the right way
to implement an image previewing. Also to finalize properlly this code, we
need more time, and i would delay this implementation later 0.9.0.

To patch your local source repository, use these command lines :

# cd digikam
# patch -p0 < preview.patch

Note : You need to re-install digiKam before to use this version because a new
menu item have been added in main interface (digikamrc file changed)

Please, give me a feedback. Thanks in advance

Previewing raw is effectively much faster with this than with the editor on my
Athlon XP 3200 / 1 Gb Ram. In the editor, it stops at 10 % and wait for at
least 30 s to load the rest. New preview is less than one second :-)

Yes, but take a care that preview isn't the RAW image data. It's a JPEG or
TIFF or PPM file embedded into Camera Settings - Exif Makernotes metadata
area. It's used by camera to display image on TV screen (it's more faster to
render a small JPEG than the RAW file).

Note this preview image is also available into JPEG, TIFF and PNG files if
Makernote is available. Preview image extraction will be possible using Exiv2
when :

- Exif data size limitation will be removed into Exiv2 about this metadata.
- MakerNotes will be updated, especially CANON, NIKON, OLYMPUS, etc. Actually,
only my Minolta makernote implementation include preview tags. This is not
very complicated to do using Exiftools tags reference.

Andreas, we have already talking about Exiv2 preview extraction in the past.
Can you give me your viewpoint in this room ?

The Exif data of JPEGs usually contains a small thumbnail (typically only
120x160 px), in JPEG or TIFF format. I guess that's pretty useless. Besides,
some Makernotes point to a larger preview image somewhere in the JPEG (but
possibly outside of the Exif data). In RAW files I have seen up to 4 images,
including the RAW image. There is no standard for these preview images, they
come in different sizes and image formats (but mostly JPEG).

I was first of all wondering if it is desireable/a good idea if these could be
accessed through Exiv2.

If so, two options come to mind:
1) extract the relevant metadata tags into ExifData and let the application do
the work.
+ Exiv2 interface remains the same
- apps need to know for each format which tags to look at
- these tags may need to be treated specially by Exiv2

2) extend the Exiv2::Image interface to access preview images
+ apps just need to decide which preview image to use if there are several
- a bit weird: the library would then give access to metadata and preview
images, but not to the actual image

For the moment I like option 2 better, although I don't know how the new
interface should look like, ideas welcome.

Regards,
Andreas

I am wondering if the following is true:

The image histogram can use (if found in cache)
1. The dcraw loaded image
2. The dcraw loaded image with halfSizeColor
3. The preview image??

The preview can use (if found in cache)
1. The dcraw loaded image
2. The embedded preview image

The image editor can use (if found in cache)
1. The dcraw loaded image

The image histogram will load
the dcraw loaded image with halfSizeColor

The preview will load
the embedded preview image

The image editor will load
the dcraw loaded image

I'm not familiar with some important facts here, so please correct me.
If we can create a hierarchy like the one above, we can implement this in the
LoadingCache. I just yesterday began to write something similar to integrate
the halfSizeColor images (I know I wrote I'd fix it "till tomorrow", but it's
football world cup)

If I had enough time I'd anyway love to write a really cool grandma-compatible
highly integrated presentation mode (tm), think of KPDF, optimized for
viewing. Talking about advanced features.

If your current solution works, i.e. it shows images properly and nothing
else, that's IMO a good and pragmatic solution for 0.9.[0,1].

yes, it can be used to give a thumbnail, not a large preview like that :

Yes, i have started to work into this way (in my DMetadata interface), using
Minolta makernote preview image. But it can work duing the limitation of size
data from Exif tags.

And me the first one, because the choose of the preview to use (in the case to
multiple previews available) is just a makernote tag selection. It can be
done easily by the host application. I think it's not necessary to make a new
interface into Exiv2 for that.

Rather not. Preview for JPEG is very small image, useless for purpose of
this functionality (cannot say about other formats).

This functionality already speeds up loading of single
image comparing to ImageEditor, and moving between images (JPEGs) is
slightly faster than in image editor. However quality of zooming(?) is
lower in this preview, for me this is acceptable.

Few comments:

- images smaller than preview area are forcibly scaled up to fill it
- some kind of context menu would be useful, proposed actions:

  - Album view (F3)
  - Edit       (F4)
  - Open in    >
  - Assign tag >
  - Remove tag >
  - Rating     >
  - Change name...

- some kind of background (important especially for horizontal images)?
- with this functionality navigation in main window is more important,
  please make navigation panel with bigger icons (file name can be moved
  to new line) and/or allow for key navigation through images in main
  window.

It's can be complex to trying to mix loading whole image using DImg and only a
preview. The implementation is different. Why not using a KIO slave like with
thumb generator ?

in fact with this implementation we can kill these 3 B.K.O files :

http://bugs.kde.org/show_bug.cgi?id=127991
http://bugs.kde.org/show_bug.cgi?id=128669
http://bugs.kde.org/show_bug.cgi?id=128914       

The code to load image is embedded in GUI thread. It's fast with RAW file, but
can take a while with JPEG, PNG, TIFF (QImage loading the whole image).

No !!! Preview is not the embedded Exif thumb (160x120 pixels). It come from
Makernote and it's not standardized. It used to render image to TV screen by
camera. For example, Preview in Minolta makernote tag "PreviewImage" :

http://owl.phy.queensu.ca/~phil/exiftool/TagNames/Minolta.html

...is always a 640x480 pixels image, in Nikon and Canon makernotes :

http://owl.phy.queensu.ca/~phil/exiftool/TagNames/Nikon.html#PreviewImage
http://owl.phy.queensu.ca/~phil/exiftool/TagNames/Canon.html#PreviewImageInfo

...is an image size depending of camera model and camera settings (640x480,
1024x768, etc.).

These tags are completly differents than standard Exif thumb tag...

There is also a preview image available into IPTC tag :

http://owl.phy.queensu.ca/~phil/exiftool/TagNames/IPTC.html#ApplicationRecord

Look the tags named ObjectPreviewFileFormat and ObjectPreviewData. There just
a lenght limitation of preview image data (256Kb), not the image size. Theses
tags can be used for example to record a 800x600 JPEG preview into large
JPEG, TIFF, PNG pictures saved by image editor !

And this is can be improved to use Makernote preview with JPEG, TIFF, and PNG.

This is depending of preview image size.

Yes. I have use a scale method. This can be fixed easily.

Well, Theme rule must be used to render background.

Yes keyboard shortcuts must be added here. TODO

Maybe one could first display the preview and
in the background (i.e. separate thread, I guess)
load the real thing which is displayed when it is finished.
This would allow to quickly go from one picture to the next
and if one of them is being looked at longer, it is already available
in optimal quality?
(I think I saw something like that in Adobe Bridge?)

BTW, one thing which I miss in digikam is
the pre-loading of the next image for a sequence of images
(this is for example realized in gqview and makes
going through a bunch of images feel very fast).

One could even think of an option to cache the
last N images (and anything related to them).
By this changing between different images back and-forth
(for example to compare their quality) would be very fast ...

Best, Arnd

This was done previously in Digikam but was removed. AFAIR reason was
that full time of loading of images in both systems (with lower quality
preview and without any preview) was the same - after many
optimisations. But maybe this problem should be revisited. When browsing
through big albums waiting for display of whole thumbnails is
irritating. In many cases I need just to recognize some colors/shapes to
decide if this photo is what I want. I don't need to wait for full
quality thumbnail and can go further.

I miss it too. Also preloading of thumbnails for album view could be
nice. I remember it was drastically cut down due to performance
issues but IMO it has gone too far. Maybe some option - like in KPDF
- to set use of cache depending on system RAM.

I wonder if Digikam could "fix" images and generate those info/images
and embed it into images.

Mostly RMB menu but I see that in regular interface some actions aren't
available from main menu, most notably:

      - Open in    >

Important due to accessibility issues.

1- I like it :-)
2- quality of jpeg images(6MP) is quite bad on my machine ??? looks like
a very quick scaling

seems a bit awkward to me. I prefer gthumb like implementation with a
small "close preview" icon on the toolbar.

be configurable .....
6- contextual menu
7- background

Ok, I understand this is more a large thumbnail for raw images.
Nevertheless, if the color sidebar tab is opened, the histogram widget will
load the real image, the same for non-raw image formats as far as I see.

So,
if we have a version of the image in the cache, we can take it (scale, convert
to QImage if necessary)
if we load the full image anyway (non-raw images), we can load it as DImg and
put it in the cache.

In the end, of course, we can all leave it as it is, use a kioslave, and think
about it later in 0.9. That's fine with me.

Hi all,

This is my second version of the patch including the background color of
preview area using theme scheme from main interface.

http://digikam3rdparty.free.fr/misc.tarballs/preview2.patch

I have add preview task to finalize into 0.9.0 TODO list (without
cache/kioslave issues, delayed later 0.9.0). This will close these B.K.O
files when the code will be commited into svn:

http://bugs.kde.org/show_bug.cgi?id=127991
http://bugs.kde.org/show_bug.cgi?id=128669
http://bugs.kde.org/show_bug.cgi?id=128914

Marcel, Paco, Achim, Gerhard your viewpoints ?

Gilles

There is a second version of my patch here :

http://digikam3rdparty.free.fr/misc.tarballs/preview2.patch

Test it and give me a feedback.

Yes, better solution for exiting from preview mode is needed (I didn't
test 2nd ver. of patch).

They could be mistaken with album history buttons. Maybe change of
interface:

- hide album history buttons but allow to assign shortcuts to them, they
  are advanced feature
- move navigation in album buttons to prominent position: nice side
  effect - more similarity in interface between Album view and Image
  Editor.

I think it depends on quality of JPEG images preview implementation.
According to poll for about 50% of users this is primary format.

Well, just press again on F3, you toggle again on album view mode. Look like
the Qt widget cache is very fast (lets F3 pressed...)

Perhaps, but not for 0.9.0 because this will change too many part of the main
digiKam implementation. My current patch have be done to not be intrusive
against the current implementation.

make distclean before, or better, remove digikam/digikam folder and recheckout
it before to apply the patch.

preview3.patch is under construction (:=)))

[Gilles Caulier-2]

This is the 3rd version of the patch. What's NEWS :

- new keyboard shortcuts :
   * PAGE UP : previous image in current collection
   * PAGE DOWN : next image  in current collection
   * HOME : first image  in current collection
   * END : last image  in current collection
   * ESC : go out previous mode (like if you press F3 again)
