Little Argyll GUI vs pacsDisplay

Little Argyll GUI is an open-source graphical front end for the ArgyllCMS color-management system. Its controls help create and use ArgyllCMS commands for display and printer calibration and profiling, as well as camera and scanner profiling. Saved parameter sets support repeated work. The program can create daylight-series spectrum files with selectable ultraviolet filtering and custom patch sets for grays, near-grays, or tones such as sepia; printer patch sets can include those additions. Documentation links appear throughout the interface. Version 1.0.1 is a Python 3 script with a GTK 3 interface built using PyGObject, and updates Argyll 3.0.0; some parameters are absent in older Argyll versions. Linux, macOS, and Windows instructions are provided. Windows setup uses MSYS2, while macOS setup uses Homebrew. On the maker’s Windows 10 MinGW-w64 system, the background selector does not work. Use requires a color measurement device, such as an i1 Pro 3 or ColorChecker Studio. The listed price is $5 as a one-time purchase payment.

pacsDisplay is an open-source project for calibrating DICOM grayscale displays and checking their image quality. Its calibration tools measure luminance response and create DICOM GSDF lookup tables. The iQC tool shows interactive quality-control patterns, including TG270-pQC, TG270-sQC, and TG270-ULN. For uniformity checks, uniLum collects luminance measurements and reports deviation from the median and mean luminance deviation. Other tools assess ambient lighting and measure luminance and illuminance. The listed compatible photometers include X-Rite i1Display Studio, Pro, and Plus; NEC SpectraSensor Pro; ColorMunki Display; Calibrite Display Pro and Plus HL; and rebranded meters. Version 6A supports external-display measurements in lumResponse and uniLum. The current release supports Windows 10 and 11. Its pdQC toolkit can be deployed from a USB drive or network without installation. The Windows installer places files in Program Files, the Public Users folder, and the Start Menu without modifying the registry or system services. Development began in 1999, and the project is distributed under the GNU General Public License v3.0.
