uiimage - Objective C: Sharpen images created with CGContextdrawPDFPage -


i create uiimages pdf cgcontextdrawpdfpage.

the quality wasn´t satisfying tried

cgcontextsetinterpolationquality(context,kcgrenderingintentdefault); 

and worked out. quality of resulting images still not enough. image looks totally blurry on ipad.

can tell me how can increase quality , sharpen image bit?

thanks help.

i better results using

uigraphicsbeginimagecontextwithoptions

instead of

uigraphicsbeginimagecontext

for beginning image context.

the parameter scale set 0.0 did trick.
