Hi all

I have bought KRpano to use for viewing 80,000+ zoomifys on our site in place of the zoomify viewer.
On the whole it works well, however on one image I noticed this problem:

http://www.powerhousemuseum.com/collecti…8337&img=120334

if you click 'Zoom Image' the error overlay pops up as the progress bar graph proceeds and these errors appear:

ERROR: decoding of "/120334/TileGroup0/2-0-2.jpg" failed
ERROR: decoding of "/120334/TileGroup0/2-1-2.jpg" failed
ERROR: decoding of "/120334/TileGroup0/2-2-2.jpg" failed (URLs shortened for sanity's sake)

Despite these errors the zoomify appears to work fine.

One annoying thing is if you click CLOSE to remove the error overlay the progress bar never goes away!!

Here is the same image working fine with the zoomify viewer:

And here is the KRpano viewer working without error on a different image:

QUESTION CONTINUES IN NEXT POST

CONTINUED:

So I began looking into this problem.

At first I thought that maybe those 3 tiles had something wrong with them and I remade the zoomify and replaced it. No change.

So then I thought I would inspect the tiles in photoshop. However... they are not there!

It appears KRpano's interpretation of the zoomify's ImageProperties.xml means it is expecting more images to be there than the Zoomify droplet actually makes.

The ImageProperties.xml file says:

<IMAGE_PROPERTIES WIDTH="2384" HEIGHT="2051" NUMTILES="124" NUMIMAGES="1" VERSION="1.8" TILESIZE="256" />

And there ARE in fact 124 tiles in the TileGroup0 directory - just none named 2-0-2.jpg, 2-1-2.jpg or 2-2-2.jpg

here is an excerpt of the listing of that directory:

0-0-0.jpg
1-0-0.jpg
1-1-0.jpg
2-0-0.jpg
2-0-1.jpg
2-1-0.jpg
2-1-1.jpg
2-2-0.jpg
2-2-1.jpg
3-0-0.jpg
3-0-1.jpg
3-0-2.jpg

Am I right in thinking KRpano is expecting there to be more tiles there than my Zoomify droplet has created?


Either way, since the zooming pano actually works is there simply some way of turning off the error overlay and making sure the loading bar graph doesn't stay there??

many thanks for any help with this excellent tool.

Hallo Klaus

if there is any more information I can give you to help with this curious issue please let me know.

Also is there a way of suppressing the error reporting?

many thanks
:L

Klaus you are great!

thanks so much for your help and attention.

Just a follow up on this: I have made KR Pano live on our site so the links I mentioned above will no longer work.

As suggested I added this to stop the errors showing:

<krpano ... showerrors="false">

However the stalled 'loading progress bar' still was visible - a quick search of the forum lead me to try this:

<progress showload="none" showwait="none" />

which removes it and everything is great now!

(although we would still love an ipad/iphone version! :)

many thanks
:L

Hello Klaus

I have PM'd you a link to the original image before Zoomify processing.

We use the old ZoomifyConverter.exe on windows - the processing of the images is usually only done once and some time during the last five years - so its probably quite an old version.

since they never get redone we haven't ever really switched over to using the photoshop way
:L

Yes Klaus I will find an image of this size and convert it for you tomorrow.

many thanks
:L

OK

I have PM'd you the results of using Zoomify's zoomifyConverter.exe on some bigger images.

many thanks
