reduce large image loading time just like the photo library in iphone

Image

Anybody know how to load the large image to become a blur image first and then only slowly load the full size of image. This will at least let the user to preview the image first other than waiting for a few second to load the full size image.





Thanks

    I know this post is old, but just in case anyone is looking for it, there is a project called NYXImagesKit that does what you are looking for.

    It has a class named NYXProgressiveImageView that is a subclass of UIImageView.

    All you have to do is:

    NYXProgressiveImageView * imgv = [[NYXProgressiveImageView alloc] init];
    imgv.frame = CGRectMake(0, 0, 320, 480);
    [imgv loadImageAtURL:[NSURL URLWithString:@"http://yourimage"]];
    [self.view addSubview:imgv];
    [imgv release];


    Also, a good option is to save your images as interlaced so that it loads with low quality and improve with the download. If the image is normal it is loaded from top to bottom.

Slow Android emulator

By User
I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
