Image Compression and save memory

var filename = new Date().getTime() + ".jpg"; currentWidth = e.media.width; currentHeight = e.media.height;

    blob = e.media;

    if(currentWidth > 500 || currentHeight > 500) {

        if(currentWidth > currentHeight) {
            newWidth = 500;
            newHeight = newWidth*currentHeight/currentWidth;
        } else {
            newHeight = 500;
            newWidth = newHeight*currentWidth/currentHeight;
        }

        blob = Titanium.UI.createImageView({image:blob,width:newWidth,height:newHeight}).toImage();
    }

    var savedfile = Ti.Filesystem.getFile(Titanium.Filesystem.getApplicationDataDirectory(),filename);
    savedfile.write(blob);

ive compressed image with this logic in perspective of height and width, but i want to know that do this logic compress images in memory too??

noo, lemme explain, take an example of camera of galaxy tab,suppose, ive installed an application in it which uses camera and after capturing image i want to reduce image size in consideration of memory .
