    How to copy a bitmap

    i have to copy one bitmap to other so that i can delete older bitmap....
    We have diff option for this one is scan line by line and put in new bitmap (slower)...
    2nd is to make a bitmapcontext and use bitblt() (degrade quality).....

    so i need to use some thing which will be faster as well as mantain quality to..
    open for all ideas........

    Re: How to copy a bitmap

    Hi,

    the fastest you probably can get is use the DataAddress() and Mem::Copy() line by line...

    BitBlt() does not degrade the quality!
