Hi.
Thanks for all responses. Some answers below may be a little outdated.
I always do a clean Classic Installation using Mageia-8-x86_64.iso .
I chose both KDE/Plasma and Gnome Desktop and do a manual selection of programmes/modules to install (eg. 100dpi.fonts, okteta, most video-players)
This is my main private "work" computer and I like to do some hobby programming so C and C++ also gets installed.
Partitions : / and swap on a SSD , and on HDD: /var and 2 partitions (had to buy a second HDD) mouted on /mnt where I have my own files in folders which are sym-linked to /home/<me> . At present I have MAG6 , 7 and now 8 installed in this way (and there is room for MAG9) .
So I can compare MAG8 and 7 .
Install Media sources : all (+ 32bit) except no DEBUG nor TESTING and only CORE BACKPORTS (no other BACKPORTS).
I think that the first guess of file type in Linux is based on the extension, but then a small program (named: file ) tries to figure out the real type.
So I think it is this small program that tells it is a TIFF image although this is probably not conpletely true.
The content and format of RAW image files may depend on sensor hardware and firmware so it comes in many flavours and thereby different file suffix. Some camera makers have (partially) chosen to use the DNG format, On
http://ufraw.sourceforge.net/Cameras.html is listed many cameras supported by UFRaw which are NOT using DNG .
The ".3FR" (and .FFF) is used by Hasselblad (probably proprietary) . But UFRaw, DarkTable, RawTherapee, Document Viewer and in Mag7 anso Gvenview can all read (and edit) the files.
The .3FR contains in my case a RAW compressed image with 39Mpixel, 3 colours at 16bit stored in about 50 MB file size. So some processing has to be done by the camera firmware !
Gwenview works perfect on normal files such as JPEG and also on another RAW format .CR2
Document Viewer calculates a downsized image at about 450 x 340 and then upscales as necessary. I am using a 4K TV as monitor and even though the pixel borders are smoothed out then it shows. It is far from the quality of Gwenview in M7.
Looking at
http://gwenview.sourceforge.net/overview it is stated : "Gwenview can load and save all image formats supported by KDE"
When I hover the mouse over a file in Dolphin tooltips are shown and for all image files including .3FR it includes a small picture of the picture as normal . So Dolphin is able to "read" the file.
The Plama System Setting > file associations have by default chosen Document Viewer in stead of Gwenview to view many image files. Maybe there is a reason for this.
Using MCC to Check the files mentioned by sturmvogel :
lib64raw20, lib64kf5kdcraw5, libkdcraw are all installed.
The requested info :
- Code: Select all
[root@localhost ~]# for pkg in $(rpm -qa --queryformat '%{RECOMMENDNAME} \n' | sort -u | grep -v '(none)'); do rpm -q ${pkg} &>/dev/null || echo ${pkg}; done
