Some of exif types are not supported #14

Closed HFN closed 7 years ago

HFN commented 8 years ago

Due to this documentation, There are 12 types of data formats for exif files. Unfortunately some of these formats is not supported in this package (e.g. value 8), Which leads to a ValueError Exception. Can you please fix it so it can be also possible to use these kinds of formats?

HFN commented 8 years ago

I'm still waiting for some answers. There are still no support for signed byte, signed short, float and double. Could you please also support these formats or at least show me a way to do it myself?

They aren't described in exif official document. If I find them in more reliable document, I'll write code to support them.

http://www.randelshofer.ch/multishow/javadoc/ch/randelshofer/media/tiff/IFDDataType.html#SSHORT lead me to http://www.alternatiff.com/resources/TIFFPM6.pdf page 7 you find the type 8. Also, https://partners.adobe.com/public/developer/en/tiff/TIFF6.pdf page 16. ExifTool use those types : https://sourceforge.net/p/exiftool/code/ci/master/tree/lib/Image/ExifTool/Exif.pm#l86

Not related but I found those too and they can be useful : http://www.exiv2.org/metadata.html http://www.sno.phy.queensu.ca/~phil/exiftool/standards.html#ref1

Thanks. I want official documents. They aren't any lib's documents. I'll check adobe's.
