QuestionNSImage become blurry after transfromation Pin

i rotate an image using this

- (NSImage*)imageRotatedByDegrees_Angle:(CGFloat)degrees
{
    [[NSGraphicsContext
      currentContext] setImageInterpolation: NSImageInterpolationNone];
    
    // Calculate the bounds for the rotated image
    // We do this by affine-transforming the bounds rectangle
    NSRect imageBounds = {NSZeroPoint, [self size]};
    NSBezierPath* boundsPath = [NSBezierPath bezierPathWithRect:imageBounds];
    NSAffineTransform* transform = [NSAffineTransform transform];
    [transform rotateByDegrees:-1.0 * degrees];// we want clockwise angles
    [boundsPath transformUsingAffineTransform:transform];
    NSRect rotatedBounds = {NSZeroPoint, [boundsPath bounds].size};
    
    // Center the image within the rotated bounds
    imageBounds.origin.x = NSMidX(rotatedBounds) - (NSWidth(imageBounds) / 2);
    imageBounds.origin.y = NSMidY(rotatedBounds) - (NSHeight(imageBounds) / 2);
    
    NSImage* rotatedImage = [[NSImage alloc] initWithSize:rotatedBounds.size];
    //NSSize new_size=[self size];
    

            NSAffineTransform* transform1 = [NSAffineTransform transform];
       
            [transform1 translateXBy:+(NSWidth(rotatedBounds) / 2)
                                yBy:+(NSHeight(rotatedBounds) / 2)];
            // Do the rotation
            [transform1 rotateByDegrees:-1.0 * degrees];
            

            [transform1 translateXBy:-(NSWidth(rotatedBounds) / 2)
                                yBy:-(NSHeight(rotatedBounds) / 2)];
        
        

         [NSGraphicsContext saveGraphicsState];
     
        
        [[NSGraphicsContext currentContext]
         setImageInterpolation:NSImageInterpolationHigh];
        
        
        [rotatedImage lockFocus];
        
        
            [transform1 concat];
        
            [self drawInRect: imageBounds fromRect:NSZeroRect operation:NSCompositeCopy fraction:1.0];
        
        
         [rotatedImage unlockFocus];
        
        [NSGraphicsContext restoreGraphicsState];
        
            
    return rotatedImage;
    
}


image is rotated but the rotated image is so blurry.

Does anyone know how to solve it?

please help me for this.
