Enum printpdf::xobject::XObject

pub enum XObject {
    Image(ImageXObject),
    Form(Box<FormXObject>),
    PostScript(PostScriptXObject),
    External(LoPdfStream),
}

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.

Variants

Image(ImageXObject)

Image XObject, for images

Form(Box<FormXObject>)

Form XObject, for PDF forms

PostScript(PostScriptXObject)

Embedded PostScript XObject, for legacy applications You can embed PostScript in a PDF, it is not recommended

External(LoPdfStream)

XObject embedded from an external stream

This is mainly used to add XObjects to the resources that the library doesn’t support natively (such as gradients, patterns, etc).

The only thing this does is to ensure that this stream is set on the /Resources dictionary of the page. The XObjectRef returned by add_xobject() is the unique name that can be used to invoke the /Do operator (by the use_xobject)
