The API of RadPdfProcessing contains two different editors, enabling you to choose between editing in a flow-like manner or using the much more powerful and flexible fixed document structure that allows you to draw on the page.
The document model of the library provides support for:
|Pages||Adding, modifying or removing of pages in a document. The properties enable you to change the size of the page, its rotation and more.|
|Automatic layout||Although the PDF format is fixed, sometimes you will need to insert the content in a way that flows on the page. RadPdfProcessing enables to achieve this easily by using blocks, tables and lists.|
|Images||Decoded on demand to achieve better performance. The API enables you to obtain the encoded image data. You can also control the image quality when saving the document.|
|Geometries||Enable you to describe the geometry of a 2D shape.|
|Form XObjects||The Form XObjects enables you to describe composite objects (consisting of text, images, vector elements, etc.) within a PDF file and reuse this content among the document, for smaller document size and better rendering performance.|
|Interactive Forms||Create and modify PDF files containing textboxes, buttons, listboxes and other interactive controls making available for the PDF file user to interactively fill some data in the PDF document and/or digitally sign the filled document. You can flatten the fields as well.|
|Digital Signature||The digital signature feature enables you to sign and validate PDF document (limited supportd in .NET Standard).|
|Clipping||You can define the outline of other content elements like images and paths.|
|Bookmarks (Outlines)||Add, remove or modify the bookmarks in a PDF document.|
|Annotations||Associate an object with a location on a page of the PDF document.|
|Destinations||Defines a particular view of a document.|
|Colors and Color Spaces||Support for different types of both.|
|Fonts||Support for the standard PDF fonts, Type0, Type1, Type 3, CIDFontType2, TrueType and more.|
|Text and Graphic properties||Provide options for changing the properties of the different elements in the document elements so you can achieve a unique look.|
|Password Protection||Support for documents encrypted with Encryption Algorithm 4 (RC4/AES-128) and Encryption Algorithm 5 with AES 256|
|Merge documents and document pages||You can combine the pages from multiple documents into a single document.|
|PdfStreamWriter||The API exposes a functionality that provides option for exporting PDF files with unmatched performance and minimized memory footprint. Extremely useful when you need to add some content to existing document, merge or split documents.|
|Import of PDF and export to PDF or plain text||You can import or export PDF files and convert PDF files to plain text.|
