Method Detail

toInlineObject

public abstract ContentObject toInlineObject(PrimitiveComposer composer)

Description copied from interface: IContentEntity

Converts this entity to its equivalent inline (dependent) object representation [PDF:1.6:4.8.6].

This method creates and shows an inline object within the target content context, returning it.

Due to its direct-content nature (opposite to the indirect-content nature of external objects (see IContentEntity.toXObject(Document))), the resulting object should be shown only one time in order not to wastefully duplicate its data.

Specified by:

toInlineObject in interface IContentEntity

Parameters:

composer - Target content composer.

Returns:

The inline object representing the entity.

toXObject

public abstract XObject toXObject(Document context)

Description copied from interface: IContentEntity

Converts this entity to its equivalent external (independent) object representation [PDF:1.6:4.7].

This method creates an external object within the target document, returning it. To show it in a content context (for example: a page), then it must be applied in an appropriate manner (see PrimitiveComposer object).

Specified by:

toXObject in interface IContentEntity

Parameters:

context - Target document.

Returns:

The external object representing the entity.
