|
This interface communicates the content scale factor from the host to the plug-in view on
|
|
systems where plug-ins cannot get this information directly like Microsoft Windows.
|
|
|
|
The host calls setContentScaleFactor directly after the plug view was attached and when the scale
|
|
factor changes (system change or window moved to another screen with different scaling settings).
|
|
The host could call setContentScaleFactor in a different context, for example: scaling the
|
|
plug-in editor for better readability.
|
|
When a plug-in handles this (by returning kResultTrue), it needs to scale the width and height of
|
|
its view by the scale factor and inform the host via a IPlugFrame::resizeView(), the host will then
|
|
call IPlugView::onSize().
|
|
|
|
Note that the host is allowed to call setContentScaleFactor() at any time the IPlugView is alive.
