Please note that they only work with an approved Adobe Reader and not all PDF readers will accept these commands.
Regarding the OP: "How to set the default value for opening a whole PDF to a 100% increase in magnification?"
Using Acrobat Pro, run the batch process (sequence) / action to launch the Open Options sequence. This sequence allows you to set values for all items in the Preview tab of the PDF document properties.
Regarding the properties of a PDF document> Initial View: Visit the open PDF Document Properties (Ctrl + D, Cmd + D). Click on the "Initial View" tab. The top panel (Layout and Zoom) allows you to configure:
Navigation Tab: Page Only | Bookmarks Bar and Page | Page Panel and Page | Application Panel and Page | Layers panel and page layout: Default | Single Page | Single Page Continuous | Two-level (facing) | Two-Up (Cover Page) | Two-sided continuous (cover page) Magnification: Default | Actual size | Suitable Page | Fit Width | Height height | Fit Visible | Percentage increase (25% to 6400%)
Non-default configuration options determine how the PDF is viewed first.
Settings for all values in all panels in the Initial View can be set for one or more PDF files using a sequence of sequences / actions (Acrobat Pro required).
This functionality is used in a corporate environment where large collections of documents are deployed on an eLibrary LAN / WAN to provide a consistent initial presentation to end users.
It also provides a content author with a mechanism to create an initial look for their expanded content (for example, a PDF document collection distributed on optical media).
Regarding a typical initial default view for created PDF: when a PDF is created through Acrobat, the default PDF document. Initial view for Layout and magnification: - | Navigation: only page - | Page Layout: Default - | Increase: default - | Open on page: 1
Regarding the Open Parameters document - As long as this document contains a few command line parameters, the primary focus of the document is to use the URL to open the starting URL for the URL.
It should be noted that the document is specific to URLs, and not with respect to UNC links (links from LAN / WAN).
