Multiple MultiScaleImages Bug

Edited on 12/04/09

Hey!

I'm expanding my photo viewer and i got in to some real trouble...

This is my website:

www.timg.nl

I want to make a new functionality: A thumbnail view.. All these thumbnails are openzoom pictures... And there is 1 big picture in the background...

Whenever i create en second MultiscaleImage and i resize the browser the background picture does not scale anymore.... :(

i've already tested whether the picture gets bigger and it DOES get bigger (image.width, image.height ) but its not visualy resizing...

Do you have any idea what this could be? it happens when the second Multiscale image gets instantiated..

Thnx in advance

I’m stuck

Hey!

Update: The problem still exists but i made a workaround:

When i copy the complete openzoom folder and rename it to openzoomSmall and change all the references from org.openzoom to org.openzoomSmall it will work...

So i think the code stores some information in de classes and when i instantiate a second multiscale image the first one will not resize...

this is only a workaround no solution...

Tim,

Thanks for reporting this. Frankly, I won't have much time to work on this. However, if you would be so kind and create the smallest possible example project that reproduces the issue you're encountering, then send it to me (daniel@gasienica.ch) and I promise to have a look at and maybe even fix it.

Cheers,
Daniel

I’m thankful

I also have this problem.

As far as I can see the problem is that every NormalizedViewport shares the same instance of the transformer as the transformer property is set in the constructor from a static variable;

transformer = NULL_TRANSFORMER

The transformer also has an instance of the NormalizedViewport so if you instantiate a new MultiscaleImage they all get transformer with the latest instantiated NormalizedViewPort.

I changed it by instantating a new tranformer in the NormalizedViewport constructor like:

transformer = new NullTransformer();

I'm not confident enough with the code to be sure this does not cause other issues.

I would like to know your thoughts on this.

Thanks
Sven

Sven,

I thought I've fixed this bug in the following commit:
http://github.com/openzoom/sdk/commit...

However, if it's still causing issues, I'd love to know!

Cheers,

I’m unsure
