Examples (iOS)

Using Perfectly Clear in iOS is very simiar to using it on OSX - just load the image and correct with a Preset or individual parameters:

1. Create engine - this should be done once when the app loads

   PFCENGINE *pEngine = PFC_CreateEngine();

2. Initialize PFCPARAM

   PFCPARAM param;
   if (bUsePresetFile) {
       // Read parameters from a preset file The_Outdoors.preset
       NSString *path = [[NSBundle mainBundle] pathForResource:@"The_Outdoors"
                                                    ofType:@"preset"];
       NSError* error = nil;
       NSString* content = [NSString stringWithContentsOfFile:path
                                                     encoding:NSUTF8StringEncoding
                                                        error:&error];
       const char *preset = [content cStringUsingEncoding:NSUTF8StringEncoding];
       // Read parameters
       PFC_ReadPresetsFromStream(param, (const char*)preset);
   } else {
       // Alternately you can initialized PFCPARAM using SetParam instead of reading from preset files.
       // This uses iAuto '21 as the default parameters
       PFC_SetParam(param);
   }
   // Optionally, you can override individual parameters:
   // param.fb.bEnabled = TRUE;
   // param.fb.bSmooth = TRUE;
   // param.fb.iSmoothLevel = 100;

3. Apply Perfectly Clear:

   int status = PFC_AutoCorrect(&im, NULL, param);

4. Build a new UIImage and display or save it:

   CGDataProviderRef provider = CGDataProviderCreateWithData(NULL,
                                                             pData,
                                                             w * h * 4,
                                                             MBEReleaseDataCallback);
   int bitsPerComponent = 8;
   int bitsPerPixel = 32;
   int bytesPerRow = 4 * w;
   CGColorSpaceRef colorSpaceRef = CGColorSpaceCreateDeviceRGB();
   CGBitmapInfo bitmapInfo = kCGBitmapByteOrderDefault;
   CGColorRenderingIntent renderingIntent = kCGRenderingIntentDefault;
   CGImageRef imf = CGImageCreate(w,
                                       h,
                                       bitsPerComponent,
                                       bitsPerPixel,
                                       bytesPerRow,
                                       colorSpaceRef,
                                       bitmapInfo,
                                       provider,NULL,NO,renderingIntent);
   
   UIImage *newImage = [UIImage imageWithCGImage:imf];

5. and last, cleanup:

   PFC_DestroyEngine(pEngine);
