android - Scaling large bitmap alternative approach -

firstly aware of recommended approach of using injustdecodebounds , insample size load bitmaps @ size close desired size. broad approach gets image approximate target.

i have though of utilising options.indensity , options.intargetdensity trick native loader scaling image more exactly desired target size. set options.indensity actual width of image , options.intargetdensity desired width , indeed image @ desired size (aspect ration happens remain same in case). set image.setdensity(density_none) on resulting image , appears work ok.

anyone know of wrong approach? thoughts on memory efficiency , image quality?

i have got improve image management opengl 2.0 , surface views.
