Structs

THIS IS NOT A PDF FORM! A form XObject can be nearly everything. PDF allows you to reuse content for the graphics stream in a FormXObject. A FormXObject is basically a layer-like content stream and can contain anything as long as it’s a valid strem. A FormXObject is intended to be used for reapeated content on one page.

GroupXObject

ImageXObject

ImageXObjectRef

OptionalContentGroup

Optional content group, for PDF layers. Only available in PDF 1.4 but (I think) lower versions of PDF allow this, too. Used to create Adobe Illustrator-like layers in PDF

PostScriptXObject

TODO, very low priority

ReferenceXObject

PDF 1.4 and higher Contains a PDF file to be embedded in the current PDF

SMask

Enums

FormType

GroupXObjectType

ImageFilter

OCGIntent

Intent to use for the optional content groups

XObject

External object that gets reference outside the PDF content stream Gets constructed similar to the ExtGState, then inserted into the /XObject dictionary on the page. You can instantiate XObjects with the /Do operator. The layer.add_xobject() (or better yet, the layer.add_image(), layer.add_form()) methods will do this for you.
