error_type CALLING_CONVENTION	PageObject_CreateFromDocument (DocumentHandle handle, PageObjectHandle *result)
	Creates a new instance.

error_type CALLING_CONVENTION	PageObject_CreateFromObject (DictionaryObjectHandle handle, PageObjectHandle *result)
	Create a new PageObject from existing low-level syntax API object.

error_type CALLING_CONVENTION	PageObject_GetContents (PageObjectHandle handle, PageContentsHandle *result)

error_type CALLING_CONVENTION	PageObject_SetMediaBox (PageObjectHandle handle, RectangleHandle value)
	A rectangle expressed in default user space units, that shall define the boundaries of the physical medium on which the page shall be displayed or printed (see 14.11.2, "Page Boundaries").

Member Function Documentation

◆ PageObject_CreateFromDocument()

error_type CALLING_CONVENTION PageObject_CreateFromDocument	(	DocumentHandle *	handle,
		PageObjectHandle **	result )

Creates a new instance.

Function creates a new indirect dictionary with it's type set to "Page".

This new entry has to be manually added to document catalog's page tree.

Friends And Related Symbol Documentation

◆ PageObject_GetResources()

error_type CALLING_CONVENTION PageObject_GetResources	(	PageObjectHandle *	handle,
		ResourceDictionaryHandle **	result )

If the page requires no resources, the value of this entry shall be an empty dictionary. Omitting the entry entirely indicates that the resources shall be inherited from an ancestor node in the page tree.

◆ PageObject_SetMediaBox()

error_type CALLING_CONVENTION PageObject_SetMediaBox	(	PageObjectHandle *	handle,
		RectangleHandle *	value )

◆ PageObject_GetBaseObject()

error_type CALLING_CONVENTION PageObject_GetBaseObject	(	PageObjectHandle *	handle,
		DictionaryObjectHandle **	result )

Useful for cases, where semantic API is not sufficient.

◆ PageObject_Release()

error_type CALLING_CONVENTION PageObject_Release ( PageObjectHandle * handle )

When the internal counter reaches zero the object is deleted. Releasing already disposed object causes undefined behavior.
