Shutter speed, ISO and aperture #36

RawImage
struct
Hey there. I've considered doing it in the past for the formats I most care about. Other projects don't bundle this functionality because it's a whole other can of worms compared to raw decoding, but there's a lot in common. A lot of the parsing is the same and saner formats will have that information accessible very easily as EXIF uses the TIFF structure for most of its work and there's already a parser for that. So I'd definitely take a PR that adds an |
Look at #37 (comment) |
What's the intended scope? Expose an EXIF blob or actually parse the EXIF data? |

By the way, how to test this library? Is there a set of RAW files to check if I broke something? |
@art-den Yeah I don't think there's much in the way of testing, and given how large RAW files are I'm not sure that a test suite belongs in this repo. However, copyright-free samples from a variety of cameras are available here: http://www.rawsamples.ch/index.php/en/ This piqued my interest as I'd like to expose the metadata and thumbnails in a NEF file. To that end I've started work on a quick NEF parser and would be happy to contribute whatever to ensure that metadata also works with Nikon files. |
To test rawloader I use the raw library from here: I have some personal scripts I use to do some checks, but I've been meaning to add to this repo a way to run quick regression testing across the whole library:
Once the initial download is done, running the test becomes fast. |
I have added exif support to almost all formats. I want to test it before submitting a pull request |
What's the status on this? It would be really useful to have |
