UIImage trukkok

Eloszor is kellett egy thumbnail-t kesziteni egy jpg-bol amihez innen szedtem az otletet es igy csinaltam meg:

NSData *imageData = [[NSData alloc] initWithContentsOfFile:filePath];

UIImage *img = [[UIImage alloc] initWithData:imageData];

UIGraphicsBeginImageContext(CGSizeMake(75.0,75.0));

[img drawInRect:CGRectMake(0.0, 0.0, 75.0, 75.0)];

UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

NSData *thumbData = UIImageJPEGRepresentation(newImage, 0.5);

[thumbData writeToFile:thumbPath atomically:YES];

Aztan itt vannak meg a kovetkezo dolgok:

• Combine 2 UIImages
• Create a UIImage from a part of another UIImage
• Save UIImage to Photo Album
