swift - iOS: When applying a CIFilter to a UIImage the result image is rotated -


when apply cifilter image captured camera result perfect when apply cifilter image captured front camera result not because image rotated whats wrong there??

my filter function given below

func applyfilter()->uiimage {     let cicontext = cicontext(options: nil)     let coreimage = ciimage(image: myimage!)     let filter = cifilter(name: "ciphotoeffectnoir" )     filter!.setdefaults()     filter!.setvalue(coreimage, forkey: kciinputimagekey)     let filteredimagedata = filter!.valueforkey(kcioutputimagekey) as! ciimage     let filteredimageref = cicontext.createcgimage(filteredimagedata, fromrect: filteredimagedata.extent)     var newimage = uiimage(cgimage: filteredimageref);      return newimage  }

make sure image size before apply filters means width should less height because image/photos taken front camera have grater width length may cause problem after applying filters. https://developer.apple.com/library/content/documentation/deviceinformation/reference/iosdevicecompatibility/cameras/cameras.html

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
