labview pda module: how can I resize image dynamically in an application?

[gbouley]

Hello every one,

 I am currently working on the development of an application on a PDA (brand Nomad) and whose OS is Windows Mobile. So I am using the PDA module of Labview 8.6.My problem is the following one: in my application I would like to be able to load images (thanks to their path) in pictures indicators. I load images with the labview “function PDA Image File Load.vi” and then my problem is that images don’t fit with the size of the indicator, and so I am only able to see the left top corner of the image…Of course, I would like to see the entire picture, but I don’t know how I can modify or resize a picture with the PDA Module, where most of the property nodes (zoom factor, scrollbars…for picures) are not available.Has someone ever faced and fixed that problem?? Any help would be really appreciated!!   PS: Attached is one part of my application!

Hello Gbouley

Thanks for your repost.

Have a look at this KBs :

Can I Resize an Image or Picture in LabVIEW?

Hope this helps.

Hi,

Indeed, like Romain D. said you have some interesting discussions where you can find some customer's experience like yours :

Thanks for your help Romain.

I think I am gonna  try to do it by building my own algorithm (as it is advised in the first link) because in LabView PDA property nodes such as zoom factor are not available.
