Out of curiosity, would you mind trying -[NSImage imageWithData:] on one of your PICT files with the text label? I am curious whether NSImage preserves the label text or not.

Here’s the code for a minimal PICT viewer app:

@interface Document ()

@property (copy) NSImage *image;

@end

@implementation Document

@synthesize image = _image;

- (NSString *)windowNibName {
    return @"Document";
}

+ (BOOL)autosavesInPlace {
    return NO;
}

- (NSData *)dataOfType:(NSString *)typeName error:(NSError **)outError {
    NSException *exception = [NSException exceptionWithName:@"UnimplementedMethod" reason:[NSString stringWithFormat:@"%@ is unimplemented", NSStringFromSelector(_cmd)] userInfo:nil];
    @throw exception;
    return nil;
}

- (BOOL)readFromData:(NSData *)data ofType:(NSString *)typeName error:(NSError **)outError {
    self.image = [[NSImage alloc] initWithData:data];
    
    if(self.image == nil) {
        if(outError) *outError = [NSError errorWithDomain:NSCocoaErrorDomain code:NSFileReadUnknownError userInfo:nil];
        return NO;
    }
    
    return YES;
}

- (IBAction)convertToTIFF:(id)sender {
    NSSavePanel *sp = [NSSavePanel savePanel];
    
    sp.allowedFileTypes = [NSArray arrayWithObject:(__bridge NSString *)kUTTypeTIFF];
    
    [sp beginSheetModalForWindow:self.windowForSheet completionHandler:^(NSInteger result) {
        if(result != NSFileHandlingPanelOKButton) {
            return;
        }
        
        NSError *error = nil;
        if(![self.image.TIFFRepresentation writeToURL:sp.URL options:NSDataWritingAtomic error:&error]) {
            [self presentError:error];
        }
    }];
}

@end

If you don’t have the dev tools installed or would just prefer for me to send me a binary, let me know.

Thanks,
Charles
