kmakemultires thumbsize ignored?

Hellkeeper · August 10, 2017 at 6:48 PM

Hey there,
got this Thumb Config for my kmakemultires:

Code

# create Thumb
makethumb=true
thumbsize=900
thumbpath=%INPUTPATH%/../thumb.jpg

But the thumbsize is ignored and the thumb is made 512x512px in size?!
How to tell kmakemultires to make it 900px?

thx

Hi,

the setting is not ignored, but the value range of that setting is currently limited at 512px.

Do you really want larger thumbnail images?
They will be ALL loaded and their memory-need needs to be respected! (the minimum memory-need in bytes is: width x height x 4 - so one 900x900 image already needs ~3MB!)

Best regards,
Klaus

Hey Klaus,

thx for the Answer.
May I ask WHERE / for what the Thumbnail Image is loaded in krpano player?
Do you mean they are all loaded within Scenes Thumb-Stripe? Or something else?

thx
Andreas

Hi,

the vtourskin.xml is using them for the thumbnail bar.

If you have a very big tour with many panos the size of the thumbnails can be an important memory and loading factor.

Best regards,
Klaus

Hey there,
alright - makes sense!

In our Case this wouldn't pose any problem as we run the Thumbs through Image Wrapper before embedding them into the Thumb-Bar. (thumburl="'.$rbStaticDomain.'/userdata/6282/pano/'.$scene['id'].'/thumb.jpg?width=240") <-- So all of the Thumbs are resized to 240x240 before outputting them ...
The higher Resolution Image is just used on the Web-Page for Preview of the Pano ...
But I guess I need to create another, larger Thumbnail for that if the Limit is 512px.

thx, bye from Tirol
Andreas

ps) Maybe you could add the Information of the 512px Limit to the Documentation: https://krpano.com/tools/kmakemultires/config/#thumbsize
