Awesome post! Thankyou for taking the time to put this together. It will be very useful everytime I need a refresh on what is going on, this sort of thing should have been the documentation.

Hi,

I am currently considering using DeepZoom's sparseimage tool to programatically generate .dzi files for an MSI on my web page.

There are 2 requirements that I need to fulfill :

1. The data that appears at different zoom levels are specific to those levels. The MSI control is actually to host a map image (from arcgis server). On zooming , for example, we should be able to see the road names as from a certain zoom level (say 100 times),but orginally, the road names should not be visible at all ...

Question : Is there a dynamic way of switching on / off subimages at different z-indexes in the msi control?

2. Is there a way to pass in arguments to the sparseimage tool to reduce processing time...for example to generate an image pyramid with x zoom levels where x can be passed as an argument ?

Thanks in advance.

kigho,

On #1,

Zoom = 1/ViewportWidth in MSI.. you can decide what SubImages to turn on/off at each level using Opacity in the SubImage, so it should be OK for you to turn on/off roads when the Zoom is high/low enough.

On #2, look into SparseImageTool and the MAXLVL parameter.. this might do what you need. You might also want to use /TS and set tile size..

Happy deep zooming

SparseImageTool Problem.

Hi,

I downloaded the beta 2 version of the deepzoom composer and I am trying to use its sparseimagetool.exe utility to generate an image pyramid.

the scenegraph file I passed as parameter contains subimages with different ZOrders.

The utility produces the .dzi file which I plug to an msi control in code-behind on startup of my web page.

However, when I read the subimage.ZIndex property of the sub images in the msi control, they are all 0.

Question :

1. How do I use the deepzoom composer to generate the .dzi file using the scenegraphfile I created ?

2. Is there a current bug in the sparseimagetool.exe utility that accounts for this issue ?

Thanks for keeping me updated .

Here is a sample snapshot of the scenegraphilefile.xml I generated programatically and want to pass to the sparseimagetool utility :

<?xml version="1.0" encoding="utf-8"?>

</SceneNode>

.....

</SceneGraph>

Images with Zorder 2 are set to be below the 1st image with zorder 3.

However, on debug when i read the zorders for subimages...they are all = 0. !!!

Thanks for your comments on this issue.
