The reason for the 50% size for raw images is that -h is used in the decoding process as this produces images half the size, which is faster. However, if I select a 100% view I would like to have a 100% view and not a 50% view ;-) So in my opinion this should be made optional. Fixed due to different approach for zooming in 0.10.x The bug is still there as of 0.10.0-beta7. No matter if you use Ctrl-Alt-0 or View->Zoom to 100%. Sorry, my fault. Confirming for Fuji, RAF files. What is worse IMO is that also in RAW import tool I can get only 50% of final image. Same for DNG files. It actually seems that the setting "Show embedded preview in full size" is ignored for RAW files. Same for JPEG files extracted from EOS 5D MII cr2 raw files (which are included as thumbnails with the 100% resolution of the raw). I tried to convert them to BMP to make sure no EXIF magic takes place, but it is the same. The zoom tool provides misleading information. It seems fixed in 1.0.0-beta4. At least for Pentax PEF and DNG. Can anyone confirm that this is fixed in 1.0.0 final release? In 1.0.0 final: Canon CR2 files (EOS 5DMII) are previewed at 100 % when "Embedded preview load full image size" is on. Embedded JPEGs in CR2 are previewed approximately at 28 % of their resolution when "Embedded preview load full image size" is off. To check native resolution of the raw file: $ identify -verbose raw+0.3.cr2 Base filename: raw+0.3.cr2 Format: CR2 (Canon Digital Camera Raw Image Format) Class: DirectClass Geometry: 5634x3753+0+0 To check native resolution of the embedded JPEG files: $ exiv2 -pp raw+0.3.cr2 Preview 1: image/jpeg, 160x120 pixels, 11423 bytes Preview 2: image/jpeg, 5616x3744 pixels, 865240 bytes (As you can see, the second preview has the same resolution as the raw data.) In 1.0.0 final: JPEGs from Panasonic FT-1 are previewed at 100 % of the native resolution when "Embedded preview load full image size" is on. JPEGs from Panasonic FT-1 are previewed at cca 35 % of the native resolution when "Embedded preview load full image size" is off. $ identify P1000044.JPG P1000044.JPG JPEG 4000x3000 4000x3000+0+0 8-bit DirectClass 5.261mb $ exiv2 -pp P1000044.JPG' Preview 1: image/jpeg, 160x120 pixels, 6332 bytes (The percentages above are my estimates of actual zoom when in digiKam reports 100 % zoom.) (In reply to comment #8) > Can anyone confirm that this is fixed in 1.0.0 final release? Canon CR2 of my own 350D (exiftool: 3456x2304) are displayed at 50% of their size when viewed with "Zoom to 100%" or Ctrl-Alt-0 and "Embedded preview load full image size" is on. Those files are displayed at the same size when "Embedded preview load full image size" is off. Nikon NEF of a D80 (exiftool: 3904x2616) or D3S (exiftool: 4288x2844) are displayed at 100% of their size when viewed with "Zoom to 100%" or Ctrl-Alt-0 and "Embedded preview load full image size" is on. Those files are displayed at (much) smaller size when "Embedded preview load full image size" is off. Test images, many of them even RAW, can be downloaded e.g. at http://www.imaging-resource.com Restarting digikam after setting "Embedded preview load full image size" didn't change anything. 1.0.0 (digikam help about) from openSUSE KDE Backports repositories for OS 11.2, digikam-1.0.0-9.1.i586. Ok, i identify the problem exactly : The "Embedded preview load full image size" label is not fine with RAW : 1/ when it's off, JPEG preview image is loaded instead RAW image data. Very fast, but image is a reduced version. 2/ when it's on, an half sized version of RAW image data are decoded instead full image size, to speed-up preview. Using full RAW image data will take a while here. So, label must be adapted there. Important : in current version from svn (1.1.0 release), with 1/, i display a short annotation over preview to said that it's not full image size (for all format). With 2/, i display nothing. For Raw, it will be fine to display another annotation.
