Methods

(inner) getDocument(src) → {PDFDocumentLoadingTask}

This is the main entry point for loading a PDF and interacting with it. NOTE: If a URL is used to fetch the PDF data a standard Fetch API call (or XHR as fallback) is used, which means it must follow same origin rules, e.g. no cross-domain requests without CORS.
Parameters:
Name Type Description
src string | TypedArray | DocumentInitParameters | PDFDataRangeTransport Can be a URL to where a PDF file is located, a typed array (Uint8Array) already populated with data or parameter object.

Type Definitions

DocumentInitParameters

Document initialization / loading parameters object.
Type:
  • Object
Properties:
Name Type Attributes Description
url string <optional>
 The URL of the PDF.
data TypedArray | Array.<number> | string <optional>
 Binary PDF data. Use typed arrays (Uint8Array) to improve the memory usage. If PDF data is BASE64-encoded, use `atob()` to convert it to a binary string first.
httpHeaders Object <optional>
 Basic authentication headers.
withCredentials boolean <optional>
 Indicates whether or not cross-site Access-Control requests should be made using credentials such as cookies or authorization headers. The default is `false`.
password string <optional>
 For decrypting password-protected PDFs.
initialData TypedArray <optional>
 A typed array with the first portion or all of the pdf data. Used by the extension since some data is already loaded before the switch to range requests.
length number <optional>
 The PDF file length. It's used for progress reports and range requests operations.
range PDFDataRangeTransport <optional>
 Allows for using a custom range transport implementation.
rangeChunkSize number <optional>
 Specify maximum number of bytes fetched per range request. The default value is DEFAULT_RANGE_CHUNK_SIZE.
worker PDFWorker <optional>
 The worker that will be used for loading and parsing the PDF data.
verbosity number <optional>
 Controls the logging level; the constants from VerbosityLevel should be used.
docBaseUrl string <optional>
 The base URL of the document, used when attempting to recover valid absolute URLs for annotations, and outline items, that (incorrectly) only specify relative URLs.
cMapUrl string <optional>
 The URL where the predefined Adobe CMaps are located. Include the trailing slash.
cMapPacked boolean <optional>
 Specifies if the Adobe CMaps are binary packed or not.
CMapReaderFactory Object <optional>
 The factory that will be used when reading built-in CMap files. Providing a custom factory is useful for environments without Fetch API or `XMLHttpRequest` support, such as Node.js. The default value is {DOMCMapReaderFactory}.
stopAtErrors boolean <optional>
 Reject certain promises, e.g. `getOperatorList`, `getTextContent`, and `RenderTask`, when the associated PDF data cannot be successfully parsed, instead of attempting to recover whatever possible of the data. The default value is `false`.
maxImageSize number <optional>
 The maximum allowed image size in total pixels, i.e. width * height. Images above this value will not be rendered. Use -1 for no limit, which is also the default value.
isEvalSupported boolean <optional>
 Determines if we can evaluate strings as JavaScript. Primarily used to improve performance of font rendering, and when parsing PDF functions. The default value is `true`.
disableFontFace boolean <optional>
 By default fonts are converted to OpenType fonts and loaded via `@font-face` rules. If disabled, fonts will be rendered using a built-in font renderer that constructs the glyphs with primitive path commands. The default value is `false`.
fontExtraProperties boolean <optional>
 Include additional properties, which are unused during rendering of PDF documents, when exporting the parsed font data from the worker-thread. This may be useful for debugging purposes (and backwards compatibility), but note that it will lead to increased memory usage. The default value is `false`.
ownerDocument HTMLDocument <optional>
 Specify an explicit document context to create elements with and to load resources, such as fonts, into. Defaults to the current document.
disableRange boolean <optional>
 Disable range request loading of PDF files. When enabled, and if the server supports partial content requests, then the PDF will be fetched in chunks. The default value is `false`.
disableStream boolean <optional>
 Disable streaming of PDF file data. By default PDF.js attempts to load PDF files in chunks. The default value is `false`.
disableAutoFetch boolean <optional>
 Disable pre-fetching of PDF file data. When range requests are enabled PDF.js will automatically keep fetching more data even if it isn't needed to display the current page. The default value is `false`. NOTE: It is also necessary to disable streaming, see above, in order for disabling of pre-fetching to work correctly.
pdfBug boolean <optional>
 Enables special hooks for debugging PDF.js (see `web/debugger.js`). The default value is `false`.

GetAnnotationsParameters

Page annotation parameters.
Type:
  • Object
Properties:
Name Type Description
intent string Determines the annotations that will be fetched, can be either 'display' (viewable annotations) or 'print' (printable annotations). If the parameter is omitted, all annotations are fetched.
Source:

getTextContentParameters

Page getTextContent parameters.
Type:
  • Object
Properties:
Name Type Description
normalizeWhitespace boolean Replaces all occurrences of whitespace with standard spaces (0x20). The default value is `false`.
disableCombineTextItems boolean Do not attempt to combine same line TextItem's. The default value is `false`.
Source:

GetViewportParameters

Page getViewport parameters.
Type:
  • Object
Properties:
Name Type Attributes Description
scale number The desired scale of the viewport.
rotation number <optional>
 The desired rotation, in degrees, of the viewport. If omitted it defaults to the page rotation.
offsetX number <optional>
 The horizontal, i.e. x-axis, offset. The default value is `0`.
offsetY number <optional>
 The vertical, i.e. y-axis, offset. The default value is `0`.
dontFlip boolean <optional>
 If true, the y-axis will not be flipped. The default value is `false`.

unsafeUrl string | undefined
newWindow boolean | undefined
count number | undefined

PDFDocumentLoadingTask

The loading task controls the operations required to load a PDF document (such as network requests) and provides a way to listen for completion, after which individual pages can be rendered.
Type:
  • Object
Properties:
Name Type Attributes Description
docId string Unique identifier for the document loading task.
destroyed boolean Whether the loading task is destroyed or not.
onPassword function <optional>
 Callback to request a password if a wrong or no password was provided. The callback receives two parameters: a function that should be called with the new password, and a reason (see PasswordResponses).
onProgress function <optional>
 Callback to be able to monitor the loading progress of the PDF file (necessary to implement e.g. a loading bar). The callback receives an {Object} with the properties `loaded` ({number}) and `total` ({number}) that indicate how many bytes are loaded.
onUnsupportedFeature function <optional>
 Callback for when an unsupported feature is used in the PDF document. The callback receives an UNSUPPORTED_FEATURES argument.
promise Promise.<PDFDocumentProxy> Promise for document loading task completion.
destroy function Abort all network requests and destroy the worker. Returns a promise that is resolved when destruction is completed.
