About Deep Zoom RRS feed

  • Question

  • Hi there,

    When I use Deep Zoom Composer to add image, it shows "the file is not a valid image file". But I can use other software to open the image with no problem at all. 

    1.  I create a new project;

    2.  I add the Jpeg Image (Size :143MB, 31227*28225 pixels);

    And then  it shows "the file is not a valid image file".

    You can try by downloading the file at https://www.dropbox.com/s/f63q56mqv8u223b/200601512.jpg

    I can add a smaller image to deep zoom,  is there size limit? 

    Any suggestions?

  • A 143 MB JPG file?

    Real Deep Zoom images have a different file format and file extension. Do you have the image saved properly?

    What exactly are you doing? How are you doing this? You don't use Deep Zoom to add an image to a website. Give us step by step.

    I doubt that anyone will download that file. Besides the size problem, it's too risky to download unknown stuff from the web.

  • A single image isn't a source for Deep Zoom.  Deep Zoom is a lot more work than that, and requires you to create many images.  (It is not a method to simply zoom one image.  It gives the impression of doing that, by using many images and images of different resolutions.)

    See: http://msdn.microsoft.com/en-us/library/cc645050(v=vs.95).aspx  for documentation.  For help if you still want to use it, go to the Silverlight forum.  (It's Silverlight, not an EW feature, and it may be the case that no one here has actually used it.) :  Here's a link, with a search for Deep Zoom:


    Be aware that not all viewers will be visiting your site using a browser that supports Silverlight (or, if it supports it, has it installed).  (Microsoft itself seems to be stepping away from Silverlight.)
