Module printpdf::xobject

Structs§

  • FormXObject
    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.
  • FormXObjectRef
  • GroupXObject
  • ImageXObject
  • ImageXObjectRef
    Named reference to an image
  • 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
    SMask dictionary. A soft mask (or SMask) is a greyscale image that is used to mask another image
  • XObjectList
    List of XObjects
  • XObjectRef
    Named reference to an XObject

Enums§

  • FormType
  • GroupXObjectType
  • ImageFilter
    Describes the format the image bytes are compressed with.
  • 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.
