Apple IPhone X

Hello!

I have read about support of iPhone 8(*), iPhone 8 plus, iPhone X in 0.19 libraw and tried to open photo from IPhone X (.HEIC), but it didn`t open. So I don't understand which kind of extension from IPhone X libraw supports now?

I have an example of picture, but can't attach it here.

c or c++ example of obtaining a specific EXIF datum?

Is there an example you can point me to that shows how to obtain some EXIF value, such as exposure time, from libraw after loading an image? Perhaps there's one in the supplied source code somewhere?

I saw that there are callbacks, but without a specific example, am not clear on how to use them.

Thank you.

Pixel values being clamped

I'm using LibRaw (through FreeImage, though that could change if necessary) to get the pixel data from raw images which then have effects applied to them, e.g. exposure, white balance.

This works well, except if I understand correctly the pixel values are scaled using black and white levels to the range 0-65535 with values outside the range effectively lost. Is it possible with LibRaw to keep the values between the black and white levels?

GPS

With regard to the GPS information parsed by libraw into...

libraw_gps_info_t parsed_gps;

...the altitude is a float; There's no other info in the header file or the API documentation.

What does this number represent? Meters? Feet? Miles? Something else?

When the info is available, I suggest it be added both to the header file(s) and the API documentation.

Version 0.18.6 crashes constantly on Mac

Hi,

just trying to update use of libraw within a Java application. Starting wit 0.17 no problems have been found to include it using Java native interface (JNI). Just upgraded to 0.18.6-Release. Now libraw keeps crashing when initializing LibRaw (processor).

Switching back to version 0.17.x will bring the application back to working.

However I'm in need to enable processing of images taken with a new Canon EOS 77D. This won't work with version 0.17. Trying to compile 0.19 from Github also didn't work to solve the problem (just did not create a lib).

I have a new sample image, how do I submit a sample?

Recently got my hands on a hasselblad 100mp image, shows up as hasselblad a6d.
I have the fff file and accompanying jpeg file from what software I don't know.
It opens and decodes okay with libraw but I notice its not in the "database".

Would the developers want a sample of the image + jpeg and how would I get it to you if you wanted it?

Thanks!
