How to stop "watermark" reducing the size of the pictures?

Dear all,

We use the watermark function to add the copyright in the bottom right  
corner of the pictures.

The pictures are taken using in camera jpeg generation, which normally  
has very high quality.

When we watermark in digikam, it reduces the size of the jpeg file  
from approximately 4Mb to 1.8Mb with a considerable loss of quality.  
We have tried setting all the parameters we could think, but without  
being able to stop this behavior. What I would like is the original  
picture with the watermark saved at the same resolution without  
additional compression  .... how do I achieve it?

Thanks for your help.

losing usability


I'm sorry I'm complaining again. I just got started with digikam 4.2 and
feel really sad, because what is probably considered an improvement, has
made things worse - at least for me (and I guess I'm not the only one).
Right now there's only one thing I want to mention:
When editing an image, after applying "local contrast" you get the
option to try it out. If you do, you get a split image, one side before,
the other, after. It's impossible to tell what is better because now
both sides compete with each other. It was much better when it was
possible to look at the whole picture in both states by moving the
cursor over the image or moving it away. This way one had the chance to
compare the entire image. Now, I have no idea how the other half of the
image might look like, and this may be vital as the other half can be
entirely different in light composition (just think - one half in the
shadow, the other in the light - it becomes useless).
I admit, I haven't dug my way through the settings yet, but if there is
a possibility to choose another way of display, then it should be right
there. It's already annoying (my impression) that I have to click the
"try out" button before I get any result. I know some people may want to
alter the settings before they apply the changes, but I was always
content with the available settings, so for me it's a step more in
working with my images.
And I still want the thumbnail list of the album images back in the
editor without having to select them first. For what is the thumbnail
sidebar if not to make it possible to have all other images available?

Well, I guess I have to put up with it, as there are no good
alternatives. But I don't really understand why digikam seems to be
loosing in usability with every new release.

Color depth in lossless formats

Hi there,

I recently got a new used camera with 14MPix and now I feel like
re-thinking my archiving options for edited images. So far, I had a
6MPix Pentax from whose PEF files I created PNG files. But with the
14MPix of the K-7, the PNGs range from approx. 69 to 76MB per image.
Outch! So I checked out the other formats that DigiKam supports.

Example (compression rates depend on particular image, of course):

PEF/RAW:  14,7MB, "16 bpp", "not calibrated"

TIFF:     72.6MB, "16 bpp", "RGB"
PNG:      70.9MB, "16 bpp", "RGB"
PGF:      62.6MB, "48 bpp", "RGB"
JPEG2000: 31.5MB, "0 bpp",  "unknown"

Now I'm wondering: What's up with the bpp values? Shouldn't they all be
the same: 48bpp (3x16 bit per pixel in RGB mode)

Also, I'm stunned by JPEG2000's apparently superior lossless performance
(and flabbergasted by the tremendously slow implementation) - or is
there simply something going wrong here?

My DigiKam Version is the one of Ubuntu 12.04.5, namely 2.5.0

I know that disk space is cheap nowadays, but I'm also doing audio
recording and video stuff, so I fill up disks quickly and the JPEG2000
compression level seems awesome to me. But how to check that it doesn't
fool me and how safe is this to still work in the future? JPEG2000 is

flickr export crashes

Hi list, 

Here, digikam crashes brutally when I attempt to export images to flickr. 
Sometimes it claims that the token is bad, and when asking for a new one, 
there is an error.

I'm using digikam 4.1 until I find time to update.

Anyone else with the same experience?

Kipi Plugin DLNA export not recognizing miniDLNA

Hello All,

on my setups, I cannot get the DLNA export plugin to work with miniDLNA.

Digikam Versions I tried: 3.5; 4.1; 4.2

I realized that at some point they changed the miniDLNA binary to miniDLANd

Any ideas?

Tag Manager: Reverse alphabetic sorting of tags

Hi list,

I just installed digiKam 4.2.0 and am playing around with
the "new Tag Manager" (my previous digiKam version was 3.5.0).
(BTW: Big thanks to Veaceslav for all those tagging

One strange thing on my machine:
Tags in the Tag Manager are displayed in reverse alphabetic
order. E.g.


The "Tags side view" on the left side displays them
alphabetically sorted:


Can someone else reproduce this behaviour?

Photos not showing in album after copy

I have just been copying some photos between albums and sub-albums and 
now when I go back to the original album the copied photos do NOT show 
up, however they are there as I can see the correct file names in 
Dolphin. I am running Digikam 4.1 btw. Is this a known bug?

Scanned thumbnails not rotated

I've fixed my scanner issue and managed to scan a batch of sketches. Some of them need to be rotated, and that works fine for the normal size picture, but the thumbnails keep their original orientation whatever I do.

How can I solve this? Is there a problem with the EXIF for pictures issued from a scanner.

Thanks for helping,

Image Quality Sorter

Hi there,
after several cycles of Image Quality Sorter I find the pictures no
corresponding Labes for the quality.
When looking at the quality labels always appear only the images in
which the quality label was manually set.

What am I doing wrong?

Thanks for your help

Digikam 4.2.0 Freeze ...


When an image is selected and I hit "properties", digikam freeze is this usual ?
(i am under Windows 7, 64 bits).
Due to a bad manipulation (?), I have lost the main menu, I didn't find the proper operation to revert... any ideas ?

Thanks a lot for your cooperation.
