(static, readonly) AnnotationsWillChangeReason

Indicates the reason why PSPDFKit.AnnotationsWillChangeEvent was emitted.

Properties:
Name Type Description
DRAW_START PSPDFKit.AnnotationsWillChangeReason

The user starts drawing an annotation.
DRAW_END PSPDFKit.AnnotationsWillChangeReason

The user stops drawing an annotation.
TEXT_EDIT_START PSPDFKit.AnnotationsWillChangeReason

The user starts typing text into an annotation.
TEXT_EDIT_END PSPDFKit.AnnotationsWillChangeReason

The user stops typing text into an annotation.
SELECT_START PSPDFKit.AnnotationsWillChangeReason

The user starts choosing an item from the picker presented.

Used for image annotations, stamp annotations and ink signature annotations.

Note that the annotation included in this event will not have any matching field values (including ID) compared to the annotation in a PSPDFKit.AnnotationsWillChangeReason.SELECT_END event. This is because the actual annotation hasn't been created yet. As a result, this annotation is used only to identify the type of annotation being selected. The only exception to this is the inkSignature field in a PSPDFKit.Annotations.InkAnnotation, which is set to true to distiguish it from a regular ink annotation.
SELECT_END PSPDFKit.AnnotationsWillChangeReason

The user stops choosing an item from the picker presented.

Used for image annotations, stamp annotations and ink signature annotations.

Note: An empty PSPDFKit.AnnotationsWillChangeEvent#annotations list indicates that the selection was cancelled.

Note that this will not be fired when cancelling the system dialog for selecting an image, because there is no way to detect when this occurs.
MOVE_START PSPDFKit.AnnotationsWillChangeReason

The user starts moving an annotation around.
MOVE_END PSPDFKit.AnnotationsWillChangeReason

The user stops moving an annotation around.
RESIZE_START PSPDFKit.AnnotationsWillChangeReason

The user starts resizing an annotation.
RESIZE_END PSPDFKit.AnnotationsWillChangeReason

The user stops resizing an annotation.
DELETE_START PSPDFKit.AnnotationsWillChangeReason

The user initiates the delete process. This will be emitted when the deletion confirmation dialog appears.
DELETE_END PSPDFKit.AnnotationsWillChangeReason

The user ends the delete process. This will be emitted when the user confirms or cancels the intention to delete an annotation.

An empty PSPDFKit.AnnotationsWillChangeEvent#annotations list indicates that the deletion was cancelled.
PROPERTY_CHANGE PSPDFKit.AnnotationsWillChangeReason

The value of one of the properties of the annotation is changed by the user. e.g. the color or the stroke width.

(static, readonly) AutoSaveMode

When working with annotations and form field values, there are multiple options when the data can get saved. The AutoSaveMode controls this behavior.

Properties:
Name Type Description
IMMEDIATE PSPDFKit.AutoSaveMode

Saves immediately whenever an attribute of the annotation changed, or whenever a form field value got updated.
INTELLIGENT PSPDFKit.AutoSaveMode

Saves annotations automatically, when the user finishes editing an annotation. For form fields, this behaves like PSPDFKit.AutoSaveMode.IMMEDIATE.
DISABLED PSPDFKit.AutoSaveMode

Never saves annotations or form field values automatically. Annotations and form field values can still be saved via PSPDFKit.Instance#saveAnnotations or PSPDFKit.Instance#saveFormFieldValues

In this mode, document signatures validation information will not be automatically updated if the document is modified, until changes are saved.

(static, readonly) CertificateChainValidationStatus

Properties:
Name Type Description
ok PSPDFKit.CertificateChainValidationStatus

The certificate chain validates correctly.
ok_but_self_signed PSPDFKit.CertificateChainValidationStatus

The certificate chain contains a self-signed certificate.
untrusted PSPDFKit.CertificateChainValidationStatus

The certificate chain contains a certificate that has been classified as "untrusted".

The certificate date is correct, but the identity is unknown because it has not been included in the list of trusted certificates and none of its parents are trusted certificates.
expired PSPDFKit.CertificateChainValidationStatus

The certificate used to sign the document has expired now. Note that the certificate may be valid at the time the document was signed, which is not checked.
not_yet_valid PSPDFKit.CertificateChainValidationStatus

The certificate used to sign the document is not valid yet.
invalid PSPDFKit.CertificateChainValidationStatus

The certificate is not valid.
revoked PSPDFKit.CertificateChainValidationStatus

The certificate has been revoked.
failed_to_retrieve_signature_contents PSPDFKit.CertificateChainValidationStatus

Could not fetch the contents of the signature.
general_validation_problem PSPDFKit.CertificateChainValidationStatus

An unknown problem happened when the certificate trust chain was validated.

Between the possible reasons for this could be that the signature is malformed, the certificate chain is too long and other unknown conditions.

(static, readonly) defaultAnnotationPresets: Object.<PSPDFKit.AnnotationPreset>

(static, readonly) PrintMode

Describes mode used to print a PDF document.

Properties:
Name Type Description
DOM PSPDFKit.PrintMode

This method will render all pages of the PDF document in advance before it sends the results to the printer. This works in all major browsers and will not give your users access to the source PDF file. However, this method is CPU-bound and memory usage scales with PDF size.

Because of its reliability and cross browsers support this method is the default.

Some caveats when using this method:

  • To achieve cross-browser support, we render the resulting images into the main window. We try to hide already existing HTML by applying display: none !important. If the printed page still contains other HTML elements, make sure to apply an appropriate print stylesheet to your web app.
  • This method will produce incorrect results, when pages of the document have different sizes. Unfortunately, there's no way to work around this issue since it's a CSS limitation.
EXPORT_PDF PSPDFKit.PrintMode

This method is built to be resource efficient and to avoid having to render all pages in advance, which might balloon memory usage to multi-GB on PDFs with 100+ pages.

It supports all common browsers, however some fall back to opening the PDF file in a new tab, which might give your users unwanted access to the source files.

Google Chrome and Microsoft Internet Explorer provide the APIs required to use the native renderer, as a fallback on other browser we generate and open a PDF in a new tab. This allows users to print the PDF in a native PDF reader which can, as opposed to browser-built implementations, talk directly to the connected printer.

When using this print mode, we can not call the PSPDFKit.RenderPageCallback when printing pages.

Note: If the PDF is password-protected, we always fall back to opening the PDF in a new tab.

(static, readonly) ScrollMode

Describes mode of page scrolling in the document view - either continuous, per spread (paginated) or disabled (changing pages through the UI is disabled).

Properties:
Name Type Description
CONTINUOUS PSPDFKit.ScrollMode

Render all pages as a list and allow smooth scrolling.

This is the default mode.
PER_SPREAD PSPDFKit.ScrollMode

Makes scrolling only possible within a spread. Whenever this mode is activated, or pages are changed when this mode is active, the zoom mode will be reset to PSPDFKit.ZoomMode.FIT_TO_VIEWPORT.
DISABLED PSPDFKit.ScrollMode

Makes scrolling only possible within a spread and doesn't allow changing pages. Whenever this mode is activated the zoom mode will be reset to PSPDFKit.ZoomMode.FIT_TO_VIEWPORT.

It requires a configuration object. When the configuration is invalid, the promise will be rejected with a PSPDFKit.Error.

Parameters:
Name Type Description
configuration PSPDFKit.Configuration

A configuration Object
Returns:

Promise that resolves in an PSPDFKit.Instance

Type
Promise.<PSPDFKit.Instance, PSPDFKit.Error>
Examples

Load PSPDFKit for Web Server

PSPDFKit.load({
  authPayload: { jwt: "xxx.xxx.xxx" },
  container: ".foo",
  documentId: "85203",

}).catch((error) => {
  console.error(error.message);
})

(static) preloadWorker(configuration) → {Promise.<void>}

Preloads the standalone WASM worker.

In cases where you don't want to load a PDF right away, the first invocation of PSPDFKit.load after allowing this function to resolve will be significantly faster.

If PSPDFKit.load is called while this function has not yet resolved, then PSPDFKit.load will simply reuse the request from this function without adding any overhead.

Parameters:
Name Type Description
configuration PSPDFKit.Configuration

A configuration Object
Returns:

Promise that resolves when preloading is complete

Type
Promise.<void>
Example
// Fetches worker asynchronously
PSPDFKit.preloadWorker(configuration);
document.querySelector("#open-pdf-button").addEventListener(async () => {
  await PSPDFKit.load({ ...configuration, pdf: "my-doc.pdf" });
});

(static) unload(target) → {boolean}

Unloads an existing PSPDFKit instance.

It requires an target parameter that is a CSS selector, an HTMLElement or the reference to a PSPDFKit.Instance returned by PSPDFKit.load.

Parameters:
Name Type Description
target HTMLElement | string | PSPDFKit.Instance

A target to unload
Throws:

Will throw an error when the target is invalid but will work when it does not have a mounted PSPDFKit for Web instance.

Type
PSPDFKit.Error
Returns:

When true, an instance of PSPDFKit for Web was unmounted.

Type
boolean
Examples

Unload PSPDFKit for Web using an instance

})
.then(() => {
  // Unload the given instance
  PSPDFKit.unload(instance)
}).catch((error) => {
  console.error(error.message);
})

Unload PSPDFKit for Web using a CSS selector

PSPDFKit.load({
  pdf: "/sales-report.pdf",
  container: ".foo",
})
.then(() => {
  // Unload the given instance
  PSPDFKit.unload(".foo")
})

Unload PSPDFKit for Web using an HTMLElement

PSPDFKit.load({
  pdf: "/sales-report.pdf",
  container: ".foo",
})
.then(() => {
  // Unload the given instance
  PSPDFKit.unload(document.querySelector(".foo"))
})

(static) viewStateFromOpenParameters() → {PSPDFKit.ViewState}

Type
PSPDFKit.ViewState

Type Definitions

AnnotationTooltipCallback(annotation)

This callback is called whenever an annotation gets selected and can be used to define and return an array of PSPDFKit.ToolItem that will be rendered in a tooltip for the given annotation.

If the callback returns an empty array then PSPDFKit won't show any tooltip for the selected annotation.

Parameters:
Name Type Description
annotation Annotation

The selected annotation.
Example

Register a AnnotationTooltipCallback handler to show a tooltip for text annotations only.

PSPDFKit.load({
  annotationTooltipCallback: function(annotation) {
    if (annotation instanceof PSPDFKit.Annotations.TextAnnotation) {
      var toolItem = {
        type: 'custom',
        title: 'tooltip item for text annotations',
        id: 'item-text-tooltip-annotation',
        className: 'TooltipItem-Text',
        onPress: function () {
          console.log(annotation)
        }
      }
      return [toolItem]
    } else {
      return []
    }
  }
  // ...
});

IsEditableAnnotationCallback(annotation)

This callback defines which annotations are read-only. This callback will receive the Annotation a user wants to modify and by returning true or false you can define if the annotation should be read-only (false) or modifiable (true).

For more information, see PSPDFKit.Configuration#isEditableAnnotation.

Parameters:
Name Type Description
annotation Annotation
Example

Only allow the modification of annotations from the same author

PSPDFKit.load({
  isEditableAnnotation: function(annotation) {
    return annotation.creatorName === myCurrentUser.name;
  },
});

RenderPageCallback(canvas, pageIndex, size)

This callback is called whenever a page is rendered or printed (only for PSPDFKit.PrintMode.DOM). You can use it to render watermarks on the page.

Make sure that the rendering commands are as efficient as possible as they might be invoked multiple times per page (once per tile).

For more information, see PSPDFKit.Configuration#renderPageCallback.

Parameters:
Name Type Description
canvas CanvasRenderingContext2D

A 2D <canvas/> rendering context.
pageIndex number

The current page index, starting with 0 for the first page.
size PSPDFKit.Geometry.Size

The size of the page that you're drawing at. The canvas is already scaled accordingly.
Example

Register a RenderPageCallback handler at configuration time.

PSPDFKit.load({
  renderPageCallback: function(ctx, pageIndex, pageSize) {
    ctx.beginPath();
    ctx.moveTo(0, 0);
    ctx.lineTo(pageSize.width, pageSize.height);
    ctx.stroke();

    ctx.font = "30px Comic Sans MS";
    ctx.fillStyle = "red";
    ctx.textAlign = "center";
    ctx.fillText(
      `This is page ${pageIndex + 1}`,
      pageSize.width / 2,
      pageSize.height / 2
    );
  }
  // ...
});

TrustedCAsCallback() → {Promise.<Array.<(ArrayBuffer|string)>>}

On Standalone, by implementing this callback you have a fine grained control over which certificates are going to be used for digital signatures validation.

For more information, see PSPDFKit.Configuration#trustedCAsCallback

Returns:

The CA certificates in DER (ArrayBuffer) or PEM (string) format. PSPDFKit.load({ trustedCAsCallback: function() { return new Promise((resolve, reject) => { fetch("/your-certificate.cer") .then(res => res.arrayBuffer()) .then(cert => resolve([cert])) .catch(reject) }); }, // ... });

Type
Promise.<Array.<(ArrayBuffer|string)>>
Example
<caption>Fetch and use custom set of certificates (Standalone)</caption>

TwoStepSignatureCallback(signaturePreparedData) → {Promise.<ArrayBuffer>}

This callback is called when a document has been prepared for digitally signing by calling PSPDFKit.Instance#signDocument. It receives the current document hash and file contents to be signed as arguments, and must return a Promise object that resolves to a PKCS7 container to sign the document with. If the returned Promise object rejects, the document will not be signed.

The provided file contents can be used as input for a cryptographic library or service of your choice to be signed (hashed and encrypted in a PKCS7 container). The file contents hash is also provided so it can be used it to verify the validity of the contents.

See this guide article for more information on how to digitally sign a document on Standalone.

Parameters:
Name Type Description
signaturePreparedData Object

Signature prepared data.

Properties
Name Type Description
