objective c - UIImage orientation changed when drawing in UIGraphicsBeginImageContext -

i want resize uiimage used below code.

uigraphicsbeginimagecontext(size); [sourceimage drawinrect:cgrectmake(0, 0, size.width, size.height)]; uiimage *destimage = uigraphicsgetimagefromcurrentimagecontext(); uigraphicsendimagecontext(); 

above code works fine orientation of destimage changed. don't know how.

source.imageorientation = 3 destimage.imageorientation = 0 

can 1 tell me how resize image same orientation sourceimage?

uiimage *scaleimage = [uiimage imagewithcgimage:destimage.cgimage                                 scale:sourceimage.scale orientation:sourceimage.imageorientation];

i getting result after resize image.

i have tried above code also. still give me opposite orientation.

resize imageview

calayer *layer; layer=self.view.layer; uigraphicsbeginimagecontext(self.view.bounds.size); cgcontextcliptorect (uigraphicsgetcurrentcontext(),captureframe); //give frame of image here(x,y,width,height) [layer renderincontext:uigraphicsgetcurrentcontext()]; uiimage *screenimage = uigraphicsgetimagefromcurrentimagecontext(); uigraphicsendimagecontext(); 

also try below code

uigraphicsbeginimagecontext(self.frame.size); [drawimage.image drawinrect:cgrectmake(0, 0, self.frame.size.width, self.frame.size.height)]; cgcontextsetlinecap(uigraphicsgetcurrentcontext(), kcglinecapround); cgcontextsetlinewidth(uigraphicsgetcurrentcontext(), 3.0); cgcontextsetrgbstrokecolor(uigraphicsgetcurrentcontext(), 0.0, 0.0, 0.0, 1.0); cgcontextstrokepath(uigraphicsgetcurrentcontext()); cgcontextflush(uigraphicsgetcurrentcontext()); drawimage.image = uigraphicsgetimagefromcurrentimagecontext(); uigraphicsendimagecontext();
