chroma

# This is a sample configuration file for the Chroma wallpaper daemon.

# Lines starting with # are comments and are ignored.

#

# Configuration file locations (checked in order):

#   1. ~/.config/chroma/chroma.conf

#   2. $XDG_CONFIG_HOME/chroma/chroma.conf

#   3. ./chroma.conf (current directory)

#

# To get started:

#   1. Copy this file to ~/.config/chroma/chroma.conf

#   2. Modify the paths to point to your wallpaper images

#   3. Use 'wlr-randr' or similar tools to find your output names

#   4. Restart chroma or send SIGHUP to reload configuration

# This image will be used for any output that doesn't have a specific mapping.

# Supports: JPEG, PNG, BMP, TGA, PSD, GIF, HDR, PIC, PPM, PGM

# Paths can be absolute or relative, ~ expansion is supported.

#

# Alternative examples:

# default_image = ~/Pictures/wallpapers/default.png

# default_image = /usr/share/wallpapers/default.jpg

# default_image = ./wallpapers/fallback.jpg

default_image = ~/.config/chroma/default.jpg

# Whether to run as a background daemon

# Usually set via command line option --daemon, but can be set here too

daemon_mode = false

# Global scaling mode for wallpapers (used as default for all outputs)

# Options: fill, fit, stretch, center

#   fill    - Fill entire output, crop if necessary (default)

#   fit     - Fit image within output, add borders if needed

#   stretch - Stretch to fill output, may distort aspect ratio

#   center  - Center image at original size

scale_mode = fill

# Global image filtering quality (used as default for all outputs)

# Options: nearest, linear, bilinear, trilinear

#   nearest   - Nearest neighbor filtering (pixelated, fast)

#   linear    - Linear filtering (smooth, default)

#   bilinear  - Bilinear filtering (smoother)

#   trilinear - Trilinear filtering (smoothest)

filter_quality = linear

# Image downsampling settings for performance optimization

# ===================================================

# Enable automatic downsampling of large images to save memory and improve performance

# Set to false to keep original resolution for all images (uses more memory!)

enable_downsampling = true

# Maximum expected output resolution

# Images larger than these dimensions may be automatically downsampled

# Adjust based on your actual monitor setup

max_output_width = 3840   # 4K width (change to 2560 for 1440p, 1920 for 1080p)

max_output_height = 2160  # 4K height (change to 1440 for 1440p, 1080 for 1080p)

# Minimum scale factor

# Prevents images from being scaled below this percentage of original size

# Useful to preserve detail on very high-resolution images

# Range: 0.1 to 1.0 (10% to 100%)

min_scale_factor = 0.25  # Don't scale below 25% of original size

# Output-specific wallpaper mappings

# ==================================

# Basic format: output.OUTPUT_NAME = /path/to/image.ext

#

# Extended format with per-output settings:

#   output.OUTPUT_NAME = /path/to/image.ext

#   output.OUTPUT_NAME.scale = fill|fit|stretch|center

#   output.OUTPUT_NAME.filter = nearest|linear|bilinear|trilinear

#

# To find your output names, run one of these commands:

#

#   Compositor Agnostic:

#   - wlr-randr (for wlroots-based compositors)

#   - wayland-info | grep wl_output

#   - kanshi list-outputs

#

#   Compositor Specific

#   - hyprctl monitors -j | jq .[].name (Hyprland specific)

#

# Common output name patterns:

#   - DP-1, DP-2, DP-3, etc. (DisplayPort)

#   - HDMI-A-1, HDMI-A-2, etc. (HDMI)

#   - eDP-1 (embedded DisplayPort, laptops)

#   - DVI-D-1, DVI-I-1 (DVI)

#   - VGA-1 (VGA, legacy)

#

#  Examples:

#  output.HDMI-A-1 = ~/Pictures/wallpaper.jpg

#  output.DP-1 = ~/Pictures/monitor1.png

#  output.DP-1.scale = fit

#  output.DP-1.filter = bilinear

#  output.DP-2 = ~/Pictures/monitor2.jpg

#  output.DP-2.scale = stretch

#  output.eDP-1 = ~/Pictures/laptop-wallpaper.jpg

#  output.eDP-1.scale = center

#  output.eDP-1.filter = trilinear
