Marked: according to this model, a mark-up is marked or not. Viewer applications have predefined icons for at least the following names: Comment, Key, Note, Help, NewParagraph, Paragraph and Insert. It has the following specific members: Members specific to Note The class Note is a concrete specialization of the abstract base class Markup. The author, creation date and subject of this mark-up.Ī note is the most common mark-up. The opacity of this mark-up (0 means fully transparent, 255 means fully opaque). The pop-up that displays the text of this mark-up. This text may contain simple formatting tags such as bold. These two properties allow you to create a complete thread of mark-ups. Respectively, all mark-ups that reply to this mark-up and the mark-up to which this mark-up replies. It has a number of properties that are common to all markup annotations. Markup is the abstract base class of all markup annotations. Mark-ups can take several visual forms of which a simple textual note is the most common one. to mark-up a typo or to mark-up a figure that is not clear enough. The peer will add comments at specific location in the document, e.g. In a typical mark-up scenario, the author of a document asks a peer to review the document. Markup annotations are used to mark-up a document. Code sample Add a link to an external PDF document shows how to add a link to a page that points to an external PDF document. The sequence of actions to execute when the mouse button is released in the Link area.Ĭode sample Add a cross-reference link inside the same document shows how to add a link to a page that points to another page. The visual effect that is used when the mouse is pressed inside the annotation area. In addition to the members inherited from Annotation, Link has the following specific members: Members specific to Link Public properties Of course you can add any number of actions of any type. To jump to a URL you add a single action of type UriAction. To jump to a destination you add a single action of type GoToAction. The link annotation is a clickable area that executes a sequence of actions. Widgets will be discussed in more detail in Forms. In theory, a field can have multiple widgets. Whether the annotation is locked in the viewer application.Īs a special case, a widget annotation (or widget) is the visual representation of a field that provides interactive access to the field value. Style of the border (Solid, Dashed, etc.) Right and Top are read-only.Ĭolor of the border (must be RgbColor for non-widget annotation). Left, Bottom, Right, Top, Width and Height The figure below shows the class hierarchy of the annotations that we currently support:Ĭlass Annotation has the following members that are common to all annotation types: Annotation members Public properties AnnotationĪnnotation is the abstract base class of all annotation classes. All annotation classes and related types live in the namespace and nested namespaces. Examples are ‘links’, ‘sticky notes’ and ‘widgets’. We have an empty server.An annotation is a rectangular area on a PDF page that the user can interact with. I’ve setup a github repository for the source code and here we have a very basic initial structure for a typical node application. Just very basic understanding of Nodejs will be enough. However, here in this post, we are not going to do any thing advance. I am assuming that you have basic knowledge of Node.js and if you are new to this, you can check few of my earlier posts for some information about nodejs in general and its dependency management. PDFKit – a JavaScript PDF generation library for Node and the browser.faker.js – generate massive amounts of fake data in the browser and node.js.You can find more information about both these node packages from following URLs: So instead of building all PDF files related functionality ourselves, there is node package called PDFKit, that abstracts all this complexity and give us a nice API to use in our NodeJS application.Īlong with PDFKit, I’ll be also use another node package faker.js which will help us to generate some data which we can use for pdf document contents. In this post we will see how to easily create PDF documents using Nodejs. Creating PDF files is a very common requirement in many software applications.
