Apply affine-clamp Filter to stretch the image so, it does not look shrunken when Gaussian blur is applied

Cgaffinetransform transform = cgaffinetransformidentity;

Cifilter *clampfilter = [Cifilter filterwithname:@ "Ciaffineclamp"];

[Clampfilter setvalue:inputimage forkey:@ "Inputimage"];

[Clampfilter setvalue:[nsvalue valuewithbytes:&transform objctype: @encode (cgaffinetransform)] forKey:@ " Inputtransform "];

Apply Gaussian blur filter with radius of 30

Cifilter *gaussianblurfilter = [Cifilter filterwithname: @ "Cigaussianblur"];

[Gaussianblurfilter setValue:clampFilter.outputImage Forkey: @ "Inputimage"];

[Gaussianblurfilter setvalue:@3 forkey:@ "Inputradius"];

Cgimageref cgimage = [Context createCGImage:gaussianBlurFilter.outputImage fromrect:[inputimage extent];

Set up output context.

Uigraphicsbeginimagecontext (frame.size);

Cgcontextref Outputcontext = Uigraphicsgetcurrentcontext ();

CGCONTEXTSCALECTM (Outputcontext, 1.0,-1.0);

CGCONTEXTTRANSLATECTM (outputcontext, 0,-frame.size.height);

Draw base image.

Cgcontextdrawimage (Outputcontext, Frame, cgimage);

Apply White Tint

Cgcontextsavegstate (Outputcontext);

Cgcontextsetfillcolorwithcolor (Outputcontext, [Uicolor colorwithwhite:1 alpha:0.2]. Cgcolor);

Cgcontextfillrect (Outputcontext, frame);

Output image is ready.
