[Darktable-users] Blue goes purple when using xmp from V1.4 on latest Fedora version (command line)

Hi All. I am using the cli version of Darktable and I have two machines, one has version 1.4 and one has 1.6.8. I am using an xmp created on the old version and with the new machine, blues go purple. I believe this is down to the gamut clipping option in the input colour profile. (There is no o

[Darktable-users] Crop with pixel accuracy

Thanks for the answer Tobias. Is it possible for the image dimensions to be shown elsewhere as you free crop. If I zoom in enough to get an accurate crop with the given resolution of the mouse actions the text gets hidden off the preview area. Matt

[Darktable-users] Crop with pixel accuracy

Hi All. I asked this before (in a slightly different way) but had no response so I thought I would have another go. When cropping by hand I can’t get the exact crop I want. Using the mouse the numbers jump by two pixels a time. As an example, I have an image from a Canon 5D which is 5634x3753. I

[Darktable-users] Crop by typing numbers

Hello all. I know how to type numbers in to the crop and rotate module to achieve an aspect ratio but I want to crop left and right as well as top and bottom which is a different thing. I guess I can do it by watching the numbers but I wondered if there was a way of typing in an x an y crop or c

[Darktable-users] 16:9 cropping produces worng pixel size oncommand line

I spotted a typo in the previous message in that I put a width of 1080 rather than 1920. Anyway, I have fixed the issue by manually typing a crop ratio but I am curious to see if I got something wrong. Attached is the xmp file. Matt > Hi All. > I have some images from a Canon 5d MkII. When I

[Darktable-users] 16:9 cropping produces worng pixel size on command line

Hi All. I have some images from a Canon 5d MkII. When I select 16:9 cropping and export a tiff with a width of 1080 the image comes out at 1080 high as I would expect. When I do this from the command line it comes out at 1082 high. If I give it a height the width of the image is 1916 pixels. Is

[Darktable-users] Crop and Rotate module produces black line with cli

Hello When I use the crop and rotate module to flip and image 180 degrees (Flip Both) the image exports fine. When I use the xmp file with darktable-cli it produces a very thin black line top to bottom right in the middle. I am now using the orientation module to achieve the same result but I p

Re: [Darktable-users] recommended spec for command line rendering.

Good. I am glad it is not me getting it wrong. 5 seconds for two images across 5 machines probably wont be to much strain on the system so I might not bother with openCL but I always like to learn about these things. Matt---

[Darktable-users] recommended spec for command line rendering.

Hello all. I was wondering what sort of spec I should be looking for when choosing machines to render raw frames to openEXR from the command line only. Should I be going for high end graphics cards or concentrate more on ram and processor power. In the old days of dcraw I used to limit the maxi

[Darktable-users] Camera orientation

Hi All I am using darktable-cli. I was wondering if there was a way of over-riding (i.e. ignoring) the camera orientation from its “smart” sensor. It is a Canon Eos 5D Mk III. I know it can be turned off in the camera menu which is fine but I would like to do it permanently. I guess I could re-

Thanks. I was struggling with a really old ATI Radeon card (2008?) and realised it probably was never going to work. I managed to get hold of a more modern machine with an Nvidia Quadro 2000 card and did a fresh install of Fedora 21. After struggling with various incomplete or non working tutor

Hi all. My learning continues. I have a Radeon [AMD/ATI] RV610 card and after installing mesa-libOpenCL.x86_64 (seemed like the right thing to do) I can’t run darktable without disabling opencl. i am running on Fedora core 20 and compiled 1.6 from the source tarball. This is the output: /opt/da

[Darktable-users] Darktable-cli on Windows.

Hi all. I know Darktable will not be developed for windows but I wondered if the command line binary could be compiled for windows, since there is no GUI etc. It would make a big difference to me and I thought I would politely ask. Thanks

[Darktable-users] Rotate from the comand line

Hi All and thanks for the replies. I think Tobias’s answer was the one I was looking for. I was hoping for a thing similar to –width along the lines of dcraw’s –t that can be stored and fetched from a mysql table. Ah well. the hard way it is then. Matt

Re: [Darktable-users] Darktable over XRDP?

[Darktable-users] Darktable over XRDP?

Hello all. Do you think it would be possible to run darktable via xwinlogon server or some such thing (currently I am failing to get XRDP to work on Fedora 20 but I can use Xwin log on server). I can’t launch darktable though. The thing is I am using darktable-cli on a server and occasionally mi

Hello all. I am a bit new to darktable and am really only interested in the command line version for now. But in order to run it one has to do it in an X windows session with an X terminal. Is there a really good reson for this because it doesn’t make sense to me to have a command line applicati
