Hi All
I hope it is fine to ask some Tiger related questions in this mailing list. My apologies if it's
not. Anyway I will go ahead and put forth my question.
I have this piece of code which I am using to save a file as JPEG file. The original source file
is also a JPEG file and I am opening it and doing some operations on it and writing it back.
The code is below.
sourceRep = [NSBitmapImageRep imageRepWithData:[srcImage
TIFFRepresentationUsingCompression:NSTIFFCompressionLZW factor:0.0]];
NSData *data = "" representationUsingType:NSJPEGFileType properties:nil];
I used exifcopy v2.5 from Hugh Thomas for copying the EXIF information from the original
file to the new file. It worked fine in Panther and Jaguar without the override option -o. But
in Tiger, it fails to copy. Even if I specify the overwrite EXIF data option to the exifcopy tool
it fails. I noticed that the JPEG data created using the above method has a IPTC header
information. It has the text Photoshop, 3.0 8BIM data in it. The exifcopy tool says that there
is already EXIF data in the destination file. Exifcopy 2.6 works fine.
I wanted to know why this is happening and how this can be disabled. I realize that Tiger
added support for copying EXIF data from one rep to another. But is there a way to disable
it completely?
Thanks
pradeep
