-------------------------------------
Hello,
I need to get the Exif info on the jpeg at the server side and i fall in this
bug.
I first tried to find a fix but searching in apple documentation i found
something simpliest.
I very new to IOS and cordova but i would like to share the way i do it:
instead of
CDVJpegHeaderWriter* exifWriter = [[CDVJpegHeaderWriter alloc] init];
NSString* headerstring = [exifWriter createExifAPP1:[info
objectForKey:@"UIImagePickerControllerMediaMetadata"]];
[exifWriter spliceExifBlockIntoJpeg:data withExifBlock:headerstring];
i do
NSDictionary *metadata = [info
objectForKey:@"UIImagePickerControllerMediaMetadata"];
if (metadata) {
CGImageSourceRef sourceImage =
CGImageSourceCreateWithData((__bridge_retained CFDataRef)data, NULL);
CFStringRef sourceType = CGImageSourceGetType(sourceImage);
CGImageDestinationRef destinationImage =
CGImageDestinationCreateWithData((__bridge CFMutableDataRef)data, sourceType,
1, NULL);
CGImageDestinationAddImageFromSource(destinationImage, sourceImage, 0,
(__bridge CFDictionaryRef)metadata);
CGImageDestinationFinalize(destinationImage);
CFRelease(sourceImage);
CFRelease(destinationImage);
}
