Camera RAW Previews

A Nextcloud app that extracts embedded previews for camera RAW images like .CR2, .CRW, .DNG, .MRW, .NEF, .NRW, .RW2, .SRW, .SRW, etc.

This app also gives you preview of Adobe Indesign files (.INDD) photos.

Requirements

• Probably memory_limit quite high.
• imagick or gd module. If imagick is available, it will use that for performance.
• For files with a TIFF preview (at least some DNG files), imagick is required

Installation

Install in Nextcloud App store. https://apps.nextcloud.com/apps/camerarawpreviews

Install in ownCloud Marketplace (older version that is not supported anymore, due to too much difference between owncloud and nextcloud now) https://marketplace.owncloud.com/apps/camerarawpreviews

Building locally

• Run "make"
• Place this app in ./apps/

Information about the perl binary

• To avoid lots of issues and problems for users I am bundling a static build of perl for x86_64
• The binary is built using an isolated docker container with this: http://software.schmorp.de/pkg/App-Staticperl.html

Troubleshooting

• If you get no preview, make sure your raw files has an embedded preview. If it looks like this, it does not have an embedded preview:

$ exiftool -json -preview:all rawfile.dng
[{
 "SourceFile": "rawfile.dng"
}]
