caption: Use out-of-process iframe PDF Viewer
default: true
deprecated: true
desc: |-
  Controls whether the PDF viewer in <ph name="PRODUCT_NAME">$1<ex>Google Chrome</ex></ph> uses an out-of-process iframe (OOPIF). This will be the new PDF viewer architecture in the future, as it is simpler and makes adding new features easier. The existing GuestView PDF viewer is an outdated, complex architecture that is being deprecated.

  When this policy is set to Enabled or not set, <ph name="PRODUCT_NAME">$1<ex>Google Chrome</ex></ph> will be able to use the OOPIF PDF viewer architecture. Once Enabled or not set, the default behavior will be decided by <ph name="PRODUCT_NAME">$1<ex>Google Chrome</ex></ph>.

  When this policy is set to Disabled, <ph name="PRODUCT_NAME">$1<ex>Google Chrome</ex></ph> will strictly use the existing GuestView PDF viewer. It embeds a web page with a separate frame tree into another web page.

  This policy is deprecated in M152 and will be removed in M155. The GuestView PDF viewer is being removed, and the out-of-process iframe (OOPIF) PDF viewer architecture will always be used.
