Scuffed command-line frontend for libraw

Disclaimer

Only tested on Linux, may or may not work on your Windows machine or Mac.

Right now this program is hard-coded to only look for .ARW (Sony) and .CR2|.CR3 (Canon) files, as those are the only ones I have easy access to. Theoretically, the actual libraw library could handle much more, but that would require me to add a bunch of file extensions that I neither know nor have samples to test.

Usage

rawinfo [-s] [-f <files>] [-d <directories>] [options]

All available options:

• -s, --silent: Do not show per-file information, useful for avoiding unnecessary output when scanning a large number of files

• -d, --directories: Directories to recursively search for raw files

• -f, --files: List of raw files to process

• --showCamera[=true|false]: Show camera name, image ISO and shutter speed

• --showLens[=true|false]: Show lens name, image focal length and aperture

• --showSize[=true|false]: Show image size (dimensions) and resolution

• --showTimestamp[=true|false]: Show image timestamp

• --showSoftware[=true|false]: Show camera software version

• --showCameraType[=true|false]: Show camera type

• --showQuality[=true|false]: Show image quality setting (e.g. raw compression level)

Boolean options show{Camera,Lens,Size,Timestamp,Software,CameraType,Quality} are all true by default.

Build dependencies

• CMake: Build system for C++

• libraw: The actual backend library

• libfmt: Formatting strings + making printing stuff in C++ bearable

• cxxopts: Command-line argument parsing

Arch Linux

# pacman -S cmake gcc libraw fmt cxxopts

Ubuntu

# apt install cmake g++ libraw-dev libfmt-dev libcxxopts-dev

Building

git clone https://github.com/pascalpuffke/rawinfo
cd rawinfo

# For some reason I couldn't get git submodules working and I can't be bothered to fix it, so you will need to clone the LibRaw and LibRaw-cmake repositories manually.
git clone https://github.com/LibRaw/LibRaw
git clone https://github.com/LibRaw/LibRaw-cmake
mkdir LibRaw-cmake/libraw
cp LibRaw/libraw/libraw_version.h LibRaw-cmake/libraw/

mkdir build
cd build

cmake ..
cmake --build .

Should generating the build files fail (cmake ..) with the message No SOURCES given to target: raw, you will need to set the LIBRAW_PATH variable.

cmake -DLIBRAW_PATH=/absolute/path/to/LibRaw/ ..

I might eventually put all this into a bash script.
