how rotate image correction direction i have placed below code , not working uiimage *images = [uiimage imagewithcgimage:[rep fullscreenimage] scale:[rep scale] orientation:0]; uiimageorientation specifies possible orientations of image: typedef enum { uiimageorientationup, uiimageorientationdown , // 180 deg rotation uiimageorientationleft , // 90 deg cw uiimageorientationright , // 90 deg ccw uiimageorientationupmirrored , // above image mirrored along // other axis. horizontal flip uiimageorientationdownmirrored , // horizontal flip uiimageorientationleftmirrored , // vertical flip uiimageorientationrightmirrored , // vertical flip } uiimageorientation; in code passing 0 , means uiimageorientationup enum value, looks default image of course. need specify parameter kind of orientation want. e.g. following code vertical image flip: uiimage *images = [uiimage imagewithcgimage:[rep fullscreenimage] scale...

for buildoptions in project.json, there similar configurations set files compiled, embedded assembly resource files , copied output directory. { include:"..", includefiles: "...", exclude: "...", excludefiles: "...", builtints:{ include: "...", exclude: "..." } } i know priority order first 4 is: excludefiles >includefiles>exclude>include. but have higher priority comparing 2 builtins? or algorithm used calculate final files?

i attempting write exception raising code blocks python code in order ensure parameters passed function meet appropriate conditions (i.e. making parameters mandatory, type-checking parameters, establishing boundary values parameters, etc...). understand satisfactorily how manually raise exceptions handling them . from numbers import number def foo(self, param1 = none, param2 = 0.0, param3 = 1.0): if (param1 == none): raise valueerror('this parameter mandatory') elif (not isinstance(param2, number)): raise valueerror('this parameter must valid numerical value') elif (param3 <= 0.0): raise valueerror('this parameter must positive number') ... this acceptable (tried , true) way of parameter checking in python, have wonder: since python not have way of writing switch-cases besides if-then-else statements, there more efficient or proper way perform task? or implementing long stretches of if-then-else statements option? ...
