Reduce time for zoom image without loosing image quality..
Posted: 2011-01-03T22:01:37-07:00
Hello All,
I am using image magick 6.6.6 version for my VC++ application. In this application i am loading image (with 1920X1080 dimensions) and increasing image size with 25% zoom.
It takes 953 milli seconds per 25% zoom, 1500 milli seconds per 50% zoom and 2344 milli seconds per 75% zoom and increasing when size increases.
code for this is:
If i am using "scale" method to zoom the time reduces but after several zoomin and zoomouts the quality of image reduced.
I want to get the same performance of the zoom with the "Zoom" method.
How can i reduce the time taking for zoom in the first case?
Can any one help me to reduce time for zoom image without loosing image quality?
Thanking you advance..
