First GUI: ArgyllGUI by Steven Greaves / Digifab.
You must download both the ArgyllCMSGUI (as a ZIP archive for Win32) and the Argyll CMS itself (fort he normal user I recommend the precompiled executables). I’ve used the following download links:
Then you have to put the unpacked ArgyllCMS files into any directory on your hard drive (e.g. C:\Program Files\Argyll_V1.0.2\ ). I then put the content of the ArgyllCMSGUI zip archive (the single file) into the bin folder of Argyll ( i.e. in my case C:\Program Files\Argyll_V1.0.2\bin\ ) and started the ArgyllCMSGui.exe. It will then ask you for the directory where you have your Argyll binaries – I have them in the same folder so I could just press OK. When I pressed Cancel, the ArgyllCMSGUI app crashed, btw.
Then you should see a screen like this:
I decided to first test the display calibration part, hence I pressed on the big icon with a display on it. Et voila:
It exposes all parameters of dispcal. The parameters are hacked into the software – so this is not guaranteed to work with any version of dispcal - but this shouldn’t be a big issue for the future. This list of parameters is probably overwhelming for all but the very experienced users – but Steve included the Argyll documentation in his app. Simply press the blue buble with the i in it and the window will expand to show the parameters and their meaning.
I’ve previously installed a software from MonacoSys (the software that came with my DTP94/Monaco Optix XR device). Since the provided driver does not work with Argyll, I had to exchange the USB driver first with the procedure as given on Graeme’s site:
http://www.argyllcms.com/doc/Installing_MSWindows.html Because if I did not, then clicking next simply resulted in the window being closed without any further feedback to the user.
After I had the right driver and changed the “Display Type” to “LCD”, clicking next resulted in a command line window with the typical dispcal „user interface“. I then simply followed the messages in this window, which was basically to self-calibrate the instrument and select the user-controls that are available for the display (brightness, contrast, gain for red, green and blue). Since my laptop display has none of these, I pressed 7 for continuing. After a while and several measured patches a file argyllcal.cal was residing in the folder of ArgyllCMSGUI.
Then a new window appeared on the screen
This window is for configuring “targen”, the Argyll application that creates the measurement patches for all devices. The “Target Colorant Type” was already set to “Video RGB”, so I pressed Next. When I did this a new patch, named argylldisplay.ti1 was created in the working directory and a new window appeared:
This window configures the dispread application. The names of the output file of the previous running applications were already inserted into the fields, beside that I had to change the display type again from CRT to LCD.
Once again you have to self-calibrate the instrument. As you see, a patch consisting of 836 patches was created by targen that is then read after any key is pressed. Before measurement starts, the calibration is applied to the display (your display’s overall color appearance may notably change).
After the vast amount of patches was read (for me it took ~2 seconds per patch, so the overall procedure took half an hour), another window of Argyll CMS GUI appeared.
In this window the profile creation parameters can be set. By default, only the most upper region is visible. I decided to only fill out the manufacturer, model and description fields so that I can distinguish the profile from other profiles I have created or will create in the future. After clinking OK, the window closed. I was wondering where the profile is expected to reside on my hard drive but couldn’t find it. However, there was a debug file created for every step of Argyll CMS GUI that contains the command line for the invoked Argyll tools. So I retyped the command in a normal CMD shell:
C:\Program Files\Argyll_V1.0.2>"C:\Program Files\Argyll_V1.0.2\bin\colprof.exe" -v -A"Lenovo" -M"Thinkpad T60 SXGA+ LCD" -D"profile created using Argyll CMS GUI
on 2008-08-19" -qm -L100 -al -iD50 -o1931_2 -tp -Ts "argylldisplay"
C:\Program Files\Argyll_V1.0.2\bin\colprof.exe: Error - Requested spectral interpretation when data not available
Basically, there was an error that the “-o” and “-i” parameter are not allowed when only colorimetric data (as is when I use a colorimeter for display profile creation) are available. So I simply removed the “-iD50 -o1931_2” from the line and I finally got my profile. Giving the default parameter on the command line should a) not be done by the GUI (since it’s the default parameter) and b) be ignored by colprof anyway. So far I have not seen a way to disable this behaviour and therefore the additional command line work-around is necessary.
Very complex interface, which is basically a window for the command line programs existing in the Argyll CMS. By having the help included, people can look up the meaning of the parameters but many non-expert users will probably not understand the technical matters. The big plus is that all knobs available in the command line tools are available and the typical workflow (the order the command line applications have to be started) is included already. The big minus is that feedback to the user is virtually zero, hence errors are not displayed and users will not know what happened without starting a shell and typing the command line which is saved in the debug files. I personally see no benefit currently in using the tool because of the zero-user-feedback.
My first shot recommendations for improvement would be to pass error messages to the user, only show a subset of the options by default and eliminate the –i/-o bug.
