Carpaccio

Pure Swift goodness for RAW and other image + metadata handling

Carpaccio is a Swift library for macOS and iOS that allows fast decoding of image data & EXIF metadata from file formats supported by CoreImage (including all the various RAW file formats supported, using the CoreImage RAW decoding capability).

• thumbnails
• metadata
• full sized image

Carpaccio uses multiple CPU cores efficiently in parallel for all of metadata, thumbnail and image data decoding.

There are no 3rd party dependencies (CoreImage filter is used for RAW decoding).

NOTE! If you are looking at this on GitHub, please be noted that the primary source for Carpaccio is to be found at gitlab.com/sashimiapp-public/carpaccio.git.

INSTALLATION

Swift Package Manager

Add Carpaccio to your Swift package as a dependency by adding the following to your Package.swift file in the dependencies array:

.package(url: "https://github.com/mz2/Carpaccio.git", from: "<version>")

If you are using Xcode 11 or newer, you can add Carpaccio by entering the URL to the repository via the File menu:

USAGE

For a toy example, see below:

guard let url = Bundle.module.url(forResource: "DP2M1726", withExtension: "X3F") else {
    return
}
let loader = ImageLoader(imageURL: url, thumbnailScheme: .fullImageIfThumbnailMissing, colorSpace: nil)

See more usage examples from the unit tests under Tests/CarpaccioTests.

TODO

Carpaccio is still a very fresh and raw (har har) library and there are many tasks to make this a more generally useful library.

• ☐ Update usage examples.
• ☑ Add tests for RAWs from a number of different camera vendors.
• ☑ GitLab CI support.
• ☑ iOS support.
