OK. I have a couple of questions.
I want to convert from tiff to jpeg and raw to jpeg etc. For tiff ->
JPEG i need to keep EXIF info and for Raw -> JPEG i need to write
exif info.
I know that i can use SIPS but it drops tags at random things like
the ISOSpeedRatings are droppped (you get an error message on the
command line rejected ISOSpeedRatings). So i started to look at using
CGImageSource and CGImageDestination to do this since i can read the
exif form the source and copy it to the destination. I need to do
resizing at the highest quality. My questions are:
1.) Are these only 10.4 interfaces?
2.) Does NSImage preserve the exif info if not:
3.) Can you parse the Exif info for tiffs and THM files using NSImage?
I would love to use sips but I need to preserve the EXIF info.
