Multires of picture size 121000x4000

I have made a multires from a picture that is 121k wide and 4k high, see http://www.rundskuer.no/krpano/sundalsnipa_horisonten.html
The result is fine, but there is a small annoyment :
- the multires level 1 is 104 tiles, 57 wide and 2 high
- I thought krpano would load only the pieces displayed, by demand
- it seems to me as all 104 tiles in level 1 is loaded before the loadwheel stops
the xml-file is the one made from the templates in the 1.08 beta 8 package.
any suggestions ?

attributes for level:

* tiledimagewidth
image width of the whole tiled image
* tiledimageheight
image height of the whole tiled image
* details
individual details setting for this level
* download - settings for downloading tiles:
o view - download only the tiles that are needed for the current view
o all - download all tiles of the current level (not recommended)
o auto - automatic, if imageheight is smaller than 2000 then all tiles are downloaded, if greater only the ones for the current view (=default)

So with this in mind,

Try adding this : download="view" like so below.

<level tiledimagewidth="28027" tiledimageheight="1032" download="view">

Let us know how it does.

the xml now looks like :
<preview type="CYLINDER" url="sundalsnipa_horisonten.tiles/preview.jpg" />

<image type="CYLINDER" multires="true" tilesize="810">
<level tiledimagewidth="112106" tiledimageheight="4126" download="view">
<cylinder url="sundalsnipa_horisonten.tiles/l3_%00v_%00h.jpg" />
</level>
<level tiledimagewidth="56053" tiledimageheight="2063">
<cylinder url="sundalsnipa_horisonten.tiles/l2_%00v_%00h.jpg" />
</level>
<level tiledimagewidth="28027" tiledimageheight="1032">
<cylinder url="sundalsnipa_horisonten.tiles/l1_%00v_%00h.jpg" />
</level>
</image>


And download="view"does not do the trick. From the log I can see that it loads 70 tiles for the initial look.

Try adding the view coding to the level 1 instead of level 3. Or add it to all ?

Level one is actually the one listed at the bottom. In fact, in my example posted above, I used level 1 code.

<level tiledimagewidth="28027" tiledimageheight="1032" download="view">
<cylinder url="sundalsnipa_horisonten.tiles/l1_%00v_%00h.jpg" />
notice the l1

it now looks like:
<image type="CYLINDER" multires="true" tilesize="810">
<level tiledimagewidth="112106" tiledimageheight="4126" download="view">
<cylinder url="sundalsnipa_horisonten.tiles/l3_%00v_%00h.jpg" />
</level>
<level tiledimagewidth="56053" tiledimageheight="2063" download="view">
<cylinder url="sundalsnipa_horisonten.tiles/l2_%00v_%00h.jpg" />
</level>
<level tiledimagewidth="28027" tiledimageheight="1032" download="view">
<cylinder url="sundalsnipa_horisonten.tiles/l1_%00v_%00h.jpg" />
</level>
</image>


but it does not work. the log shows that 70 level 1 tiles is loaded at startup.
this is what one tile look like: http://www.rundskuer.no/krpano/sundalsni…/l1_001_001.jpg

Problem solved, sort of ! I have commented out the preview:

<preview type="CYLINDER" url="sundalsnipa_horisonten.tiles/preview.jpg"

It now loads 6 tiles instead of 70 and the panorama loads at no time.
Its OK for me, but maybe there is something fishy in the template or elsewhere ?

Hi,

the download="view" setting at the <level> tag should do it...
maybe the old xml was still in the browser cache in your first try...?

best regards,
Klaus
