Hello,

I have some RAF images from a FujiFilm GFX100S.
They are 16-bit per colour.
I want to enhance the colours, but when I save, XnView reduces the dimensions from 11760 x 8734 to 4000 x 3000

XnView MP Windows Version 0.99.1 64bits (Sep 23 2021)

I must be missing a setting somewhere - can anyone help?

Update: Exif has dimensions as 4000 x 3000, somehow....?
Will try to edit with exiftool

cheers
Murray

In the viewer, File > Format settings... > Read tab -- Camera RAW

Thanks cday, but.... I'm not sure which variable to change

And moving along the exiftool command line option, I changed exifimagewidth and exifimageheight, and it now reads correctly in the XnView EXIF tab, but still 4000 x 3000 in the XnView Exiftool tab !

My understanding is that with Use - Half size selected your images will be opened at those pixel dimension rather than the image's full dimensions, so you probably need to select Full size.

I did try that, but no change to saved jpeg or tiff - they are still 4000 x 3000

If you look at the opened images's properties in Edit > Properties... (or the 'i' symbol on the toolbar) are the images being opened with those dimensions?

[xnview]

could you send me a sample file?

[MurrayW]

Hi Pierre,

Edit>Properties Width = 5831 / Height = 4376

See screen grab.
File list reports 11760 x 8734
EXIF reports 4000 x 3000

"could you send me a sample file?"

I attempted attaching a file.
The image files are *.RAF which is not supported.
And they are too big = 133 MB...

could you send me a sample file?

XnTriq - good thinking....

here is a link to one of the RAFs: https://drive.google.com/drive/folders/ ... sp=sharing
If anyone is interested it was taken from a Cessna flying about 1800 metres above ground level.

Also, I downloaded two RAFs from the sites you linked.
Within the XnView main window/file manager view, they both report 11760x8734 under properties
And, they both report 4000 x 3000 in the EXIF and ExifTool Info tabs.

[xnview]

by default the embedded jpeg is loaded (4000x3000), please change in Formats>Read>Camera RAW - use Full size when batch convert

[MurrayW]

I changed Formats>Read>Camera RAW to Full size

output image as jpg/tif/png is now 11662 x 8752 (original was 11760 x 8734)

Another observation: Although the RAF images out of the camera are 11760 x 8734, the jpg out of the camera is
11648 x 8736

Anyway, I think the difference now is insignificant.

thankyou for you help.

I told XnView to use Full size in Tools → Settings… → Formats → Read → Camera RAW. Depending on my configuration of RAWUseLibRaw, …

right, this version use new RAW processor so i need to check...
As workaround, you can disable it in xnview.ini

Code: Select all

RAWUseLibRaw=false

… XnView reports different dimensions and bit depth for MurrayW's sample (DSCF9716.RAF):

• RAWUseLibRaw=true → LibRaw → w11662 × h8752 × 24 bpp

  

• RAWUseLibRaw=false → dcraw → w11760 × h8734 × 48 bpp

I found an ORF sample and was expecting that changing the setting from Embedded preview to Full size would fix the issue. But it didn't

Prior to version 0.99.0, MP's RAW functions were “based on dcraw from Dave Coffin” (Help → About → Credits). Later versions use “Libraw instead of dcraw”. So I changed the value for the RAWUseLibRaw entry in the [Load] section of xnview.ini from true to false. XnView now reports the correct dimensions, regardless of the settings in Tools → Settings… → Formats → Read → Camera RAW.
