Re: Auto-Scaling in Phoebus Display Builder

[Jure Varlec via Tech-talk <tech-talk at aps.anl.gov>]

Hello Vishnu,

I don't know about auto-scaling, but it's possible to manually scale a display by setting the zoom factor. Doing so manually for every window is, of course, tedious. So, recent versions of Phoebus have a setting org.csstudio.display.builder.runtime/default_zoom_factor, expressed as percentage. This allows you to configure Phoebus for the monitors used at a particular workstation, or for an operator to set the scaling factor to whatever is pleasing to their eyes.

Best,
Jure

Dear Phoebus Team,

I am migrating displays from CSS BOY OPI Editor to Phoebus Display Builder.

In BOY OPI Editor, it is possible to enable auto-sizing or auto-scaling so that displays and widgets automatically adjust to different computer monitor resolutions at runtime.

Could you please advise whether Phoebus Display Builder provides a similar feature? If so, how can it be enabled or configured so that a display automatically adapts to the screen resolution of the client computer?

If automatic scaling is not currently supported, I would appreciate any recommendations or best practices for designing displays that can be used across monitors with different resolutions.

Thank you for your assistance.

Best regards,

Vishnu
