Hi all,
Recently I have been playing with adding exif data to image files on disk.
I found this nice blog <http://caffeinatedcocoa.com/blog/?p=7> entry which
shows how. However, Im not able to set aperture, ISO and shutter speeds from
my code, here (showing literal values):
......
[exifDict setValue: @"800"
forKey:(NSString *) kCGImagePropertyExifISOSpeedRatings];
[exifDict setValue: @"28/5"
forKey: (NSString *)
kCGImagePropertyExifApertureValue];
[exifDict setValue:@"-1507/1140"
forKey: (NSString *) kCGImagePropertyExifShutterSpeedValue];
NSMutableDictionary *metaData = [NSMutableDictionary dictionary];
[metaData setObject: exifDict forKey:(NSString
*)kCGImagePropertyExifDictionary];
CGImageDestinationAddImageFromSource(destination,source,0,
(CFDictionaryRef) metaData);
CGImageDestinationFinalize(destination);
.....
However I was able to set the kCGImagePropertyTIFFMake property. Are the
values for these properties of the wrong format ? How does one set these
exif meta data ? Thanks.
