If I want to zoom in or zoom out a picture when the picture is already shown on LCD. what procedure should be done. Should I use tivxVpacMscScaleNode to create a node dynamically? where I implement the scale node?

Hi,

Msc does not support upscaling, it can do only downscaling.

For zoom in/out, i would suggest to refer to below faq.

I tried the patch and it works fine.User can control the picture position by inputted command.

Is this patch able to zoom in/zoom out? Or some other nodes should be added to implemente the function?

Only DSS pipeline supports the scalar, so zoom in/out can be supported in DSS only.
