LVPDA 8.5 picture set origin, scale factor??

Hi!

 

I want to display an image on the screen of the PDA. It will be a navigation like application:  i have to show a small detail of a bigger image, but always another detail. In desktop applications I can do this with changing the "origin" and "scale factor" property of the picture. But if I use these invoke properties of a picture with PDA target settings, i get a "target specific" error message. How to use these without getting error / is there another simple way to do this?

 

Thanks:

Hello,

In order to use those functions , you have to use ActiveX Property Nodes, linked to the image you want to process. Please reply with the error you recieve so that I can try to help you.

Hello,

Thank you for your answer.

 

The error message box looks as following:

"Target specific errosrs and warnings:

        Property Node 'Picture':     (nothing)

 

Details:

Could not get error details"

 

"you have to use ActiveX Property Nodes, linked to the image you want to process" - I don't really understand what this means, and how to do it? 

 

Regards,

You can unflatten the pixmap and then use the Array Subset primitive to get the part of the picture you want to display.

 

If you want to resize the image, you can use the example found here, but you should note its performance is not very good with large images.
