Parameters
Properties
allowExport
Control whether or not the export PDF button in the toolbar should be disabled. If the user has insufficient permissions, the feature will automatically be disabled.
This feature requires the download permission in the JWT.
It is possible to remove the export PDF button with the Toolbar API.
Default Value
trueallowPrinting
Control whether or not the printing button in the toolbar should be disabled. If the user has insufficient permissions, the feature will automatically be disabled.
This feature requires the download permission in the JWT, because on some browsers we have to
fall back to downloading the PDF in order to allow performant printing.
It is possible to remove the print button with the Toolbar API.
Default Value
truecanScrollWhileDrawing
This flag controls whether to enable/disable finger scrolling during Ink Drawing and Ink Erasing using a pen.
- When set to
false, (default), scrolling with the finger in drawing mode is disabled. - When set to
true, once a pen input has been detected, finger input will result in scrolling the document. The pen detection state is shared across all pages, so switching pages does not reset the behavior.
Example
instance.setViewState(viewState => (
viewState.set("canScrollWhileDrawing", true)
));
Default Value
falsecommentDisplay
Controls how comments are displayed in the viewer in desktop and tablet modes. In mobile devices, comments are always displayed in a drawer a the bottom of the viewport:
- NutrientViewer.CommentDisplay.FITTING: Comments are displayed in a dialog or floating depending on the available viewport space. This is the default value.
- NutrientViewer.CommentDisplay.POPOVER: Comments are displayed in a dialog next to their reference annotation marker.
- NutrientViewer.CommentDisplay.FLOATING: Comments are displayed floating next to the page side, at the same height as their reference annotation marker, except when ViewState#zoom is set to .ZoomeMode#FIT_TO_WIDTH`, in which case they are displayed in a popover dialog instead.
Default Value
currentPageIndex
The page index of the page that's currently visible. If there is more than one page visible
this will return the page that is using the most space in the viewport. The pageIndex is
zero-based and has a maximum value of totalPageCount - 1.
Default Value
0disablePointSnapping
Snapping to the nearest point is enabled by default in ur SDK for measurement tools. It can be disabled by this API.
Example
instance.setViewState(viewState =>
viewState.set("disablePointSnapping", true)
);
Default Value
falseenableAnnotationToolbar
Set this to false if you want NutrientViewer to disable the annotation toolbar when an annotation is being created or modified.
Default Value
trueformDesignMode
This flag controls what kind of UI interaction is active for widget annotations.
- When set to
false, (default), clicking on a widget annotation will allow to modify its value. - When set to
true, clicking on a widget annotation will select it and allow moving, resizing and deleting it using the annotation toolbar.
This flag can only be set to true if the Form Creator component is included
in the license and the current backend supports it.
Example
instance.setViewState(viewState => (
viewState.set("formDesignMode", true)
));

| null
Controls the current interaction mode in the viewer. When this value is changed, we will make sure that the state is properly transformed.
If, for example, the user is currently creating an ink annotation and you change this value to
InteractionMode.TEXT, we will delete the current in-memory ink annotation.
For a list of all available mode, please refer to InteractionMode.
If this value is null, no interaction mode will be enabled. This corresponds to the default mode that allows text selection and scrolling using the mouse wheel or scrollbars (and panning on mobile devices).
Example
instance.setViewState(viewState => (
viewState.set("interactionMode", NutrientViewer.InteractionMode.PAN)
));
Default Value
nullkeepFirstSpreadAsSinglePage
When this is enabled, the first spread will always show a single page, even when LayoutMode.DOUBLE is enabled. This is useful for magazines that want to show a cover page before the regular content starts.
A spread is a container for either one or two pages, based on the configured ViewState#layoutMode.
Default Value
falsekeepSelectedTool
This flag controls whether a selected tool should maintain its selected state after an annotation is created
- When set to
false, (default), after an annotation has been created the tool is not selected anymore. - When set to
true, the tool used to create the annotation will still be selected and so it'll be possible to keep adding annotations.
This feature is available for Note Annotation, Text Annotation, Redaction Annotation, Shape Annotation and Comments. Ink Annotation behaves like this by default, the ink tool stays selected until its deselected either programmatically or via the UI.
Example
instance.setViewState(viewState => (
viewState.set("keepSelectedTool", true)
));
Default Value
falselayoutMode
Controls how pages inside a view are displayed.
Default Value
pageCursor
{ … }
Configuration for cursor behavior keyed by input modality.
The keyboard property is a function that receives the current InteractionMode
and returns configuration for that mode. This allows per-mode configuration.
Supported InteractionModes for Keyboard Creation
When keyboard returns { enabled: true } for a mode:
- NOTE, TEXT, CALLOUT - single point placement
- SHAPE_LINE, SHAPE_RECTANGLE, SHAPE_ELLIPSE - 2 point placement
- SHAPE_POLYGON, SHAPE_POLYLINE - multi-point (Shift+Enter to complete)
| Property | Description |
|---|---|
| keyboard | Function that returns keyboard modality configuration for the given InteractionMode. This allows per-mode configuration (e.g., disable keyboard for some modes). |
Example
// Disable keyboard for all modes
instance.setViewState(viewState => (
viewState.set("pageCursor", { keyboard: () => ({ enabled: false }) })
));
// Disable keyboard only for INK mode
instance.setViewState(viewState => (
viewState.set("pageCursor", {
keyboard: (mode) => ({ enabled: mode !== InteractionMode.INK })
})
));
Default Value
{ keyboard: () => ({ enabled: true }) }pageSpacing
The spacing between pages in pixels. This value will adjust to the current zoom level, so when you zoom in, it does not appear fixed to the viewport. This spacing only applies for LayoutMode.DOUBLE.
Default Value
0pagesRotation
The current rotation of all pages. The value is in degrees and describes a clockwise rotation.
Can either be 0°, 90°, 180°, or 270°. Negative values and values above 270 are normalized to one of the valid rotations.
When a page rotation is set, the values are not persisted in the PDF. This setting only affects how the PDF is viewed in the application.
Example
instance.setViewState(viewState => viewState.set("pagesRotation", -450))
// ... later
instance.viewState.pagesRotation; // => 270
Default Value
0prerenderedPageSpreads
Number of page spreads to prerender.
Apart from the current page, Nutrient Web SDK prerenders a specific number of page spreads before and after the current page to improve the user experience when scrolling through the document.
A page spread is a container for either one or two pages, based on the configured layout mode. The number of prerendered page spreads is set to 5 by default, which means that Nutrient Web SDK will prerender 5 page spreads before and after the current page.
If set to null, all the page spreads in the document will be prerendered. This setting is not recommended for large documents, as it may
lead to performance issues.
Example
// Prerender 10 page spreads
instance.setViewState(viewState =>
viewState.set("prerenderedPageSpreads", 10)
);
// Prerender all page spreads
instance.setViewState(viewState =>
viewState.set("prerenderedPageSpreads", null)
);
Default Value
5previewRedactionMode
This flag controls whether to show the marked state or redacted state for redaction annotations.
- When set to
false, (default), the marked state of redaction annotations will be shown. - When set to
true, the redacted state of redaction annotations will be used.
This flag can only be set to true if the Redactions component is included
in the license.
Example
instance.setViewState(viewState => (
viewState.set("previewRedactionMode", true)
));
Default Value
falsereadOnly
When the read only mode is activated, the UI for creating, updating and deleting annotations will be completely hidden. In addition, the user will also no longer be able to select annotations or modify form field values.
However, it is still possible to add annotations programmatically.
If a read only mode is specified within the JWT itself or in the PDF document permissions, and NutrientViewer.Options.IGNORE_DOCUMENT_PERMISSIONS is not set, this option cannot be unset.
Default Value
falseresolvedLayoutMode
When in LayoutMode.AUTO mode, this property is set to the actual rendered layout mode, which can either be LayoutMode.SINGLE or LayoutMode.DOUBLE. It can be used to be notified when the layout mode changes while still being in LayoutMode.AUTO mode: if the rendered layout mode changes while in NutrientViewer.LayoutMode.AUTO (because of user UI interactions, for example), the viewState.change event will be dispatched, and this property will hold the updated value.
Example
instance.addEventListener("viewState.change", (viewState) => {
console.log(viewState.resolvedLayoutMode);
});
scrollMode
Controls how pages can be scrolled.
Default Value
showAIAssistant
When this is enabled, the AI Assistant chat dialog will be shown. If this is disabled, the chat dialog will not be shown.
Example
NutrientViewer.load({
initialViewState: new NutrientViewer.ViewState({
showAIAssistant: true,
}),
});
Default Value
falseshowAnnotationNotes
When this is set to false, annotation notes will no longer be rendered.
Default Value
trueshowAnnotations
When this is set to false, annotations will no longer be rendered.
This option can also be set to false, when NutrientViewer.ViewState#readOnly mode is enabled.
Default Value
trueshowComments
When this is set to false, comments will no longer be rendered.
NutrientViewer ignores this value when you haven't purchased the comments component.
Default Value
trueshowSignatureValidationStatus
Controls when the digital signature validation UI will be shown.
Example
instance.setViewState(viewState => (
viewState.set("showSignatureValidationStatus", NutrientViewer.ShowSignatureValidationStatusMode.IF_SIGNED)
));
Default Value
showToolbar
Set this to true if you want a toolbar for navigation and annotation controls or false
if you don't.
Default Value

| undefined
Controls the current sidebar mode in the viewer.
For a list of all available mode, please refer to SidebarMode. This can also be set to a custom sidebar ID corresponding to a sidebar passed in ui.sidebar.
If this value is null, the sidebar is hidden. This corresponds to the default mode.
Example
instance.setViewState(viewState => (
viewState.set("sidebarMode", NutrientViewer.SidebarMode.THUMBNAILS)
));
Default Value
nullsidebarOptions
| { [key: string]: any }
| { ANNOTATIONS: AnnotationsSidebarOptions }
| { LAYERS: LayersSidebarOptions }
| { ATTACHMENTS: AttachmentsSidebarOptions }
Defines specific options that affect each individual sidebar.
For a list of all available options, please refer to SidebarOptions.
Example
Customizing the annotations sidebar to include only Text and Highlight annotations
instance.setViewState(viewState => (
viewState.set("sidebarOptions", {
[NutrientViewer.SidebarMode.ANNOTATIONS]: {
includeContent: [
NutrientViewer.Annotations.TextAnnotation,
NutrientViewer.Annotations.HighlightAnnotation,
],
},
}
)
));
Customizing the annotations sidebar to include Comments
instance.setViewState(viewState => (
viewState.set("sidebarOptions", {
[NutrientViewer.SidebarMode.ANNOTATIONS]: {
includeContent: [
...NutrientViewer.defaultAnnotationsSidebarContent,
NutrientViewer.Comment,
],
},
}
)
));
sidebarPlacement
Controls the current sidebar placement in the viewer.
Example
instance.setViewState(viewState => (
viewState.set("sidebarPlacement", NutrientViewer.SidebarPlacement.END)
));
Default Value
nullsidebarWidth
Controls the width of the sidebar in client, pixel units. Changing the ViewState.sidebarMode does not affect this value.
The default value depends on the current viewport width: if the viewport width is less than 768px, the sidebar will take 100% of the viewport width by default. If the viewport width is greater, the sidebar will take 300px by default.
Example
instance.setViewState(viewState => (
viewState.set("sidebarWidth", 400)
));
spreadSpacing
The spacing between spreads in pixels. This value will adjust to the current zoom level, so when you zoom in, it does not appear fixed to the viewport. This spacing only applies for ScrollMode.CONTINUOUS.
A spread is a container for either one or two pages, based on the configured ViewState#layoutMode.
Default Value
20viewportPadding
{ … }
The padding between the viewport and the document in pixels. This value will not increase, when you zoom in.
The horizontal value will be used as padding-left and padding-right and the vertical
value for padding-top and padding-bottom. The same value for both sides will be used, this
means that horizontal: 20 is equal to padding-left: 20px; padding-right: 20px;.
When you set those values to zero, there will be no space between the viewport and the document.
| Property | Description |
|---|---|
| horizontal | The horizontal padding for left and right in pixel. |
| vertical | The vertical padding for top and bottom in pixel. |
Default Value
{ horizontal: 20, vertical: 20 }zoom
Controls the current zoom factor. This could either be a number multiplier or a ZoomConfiguration or a ZoomMode.
If a number value is used, it must be between Instance#minimumZoomLevel and Instance#maximumZoomLevel.
Note: Using a ZoomMode} will override the padding set using ViewState#viewportPadding
Default Value
{
* zoomMode: NutrientViewer.ZoomMode.AUTO,
* wheelZoomMode: NutrientViewer.WheelZoomMode.WITH_CTRL,
* options: {
* enableKeyboardZoom: true,
* enableGestureZoom: true,
* },
* }
zoomStep
Controls the zoom step when zooming in or out using the toolbar buttons.
Example
instance.setViewState(viewState => (
viewState.set("zoomStep", 1.1)
));
Default Value
1.25Methods
Creates a new ViewState with a
currentPageIndexincreased by one.This method cannot be called on an instance of ViewState without an Instance assigned. You can use this method on all view states returned by Instance#viewState and Instance#setViewState.
When you hit
{@link Instance#totalPageCount} - 1, it will not update the state.
Creates a new ViewState with a
currentPageIndexdecreased by one.When you hit
0, it will not update the state.
Creates a new ViewState with a specific zoom level that is 25% greater than the current zoom level.
If a ZoomMode is set, it will overwrite it with a number value (which will no longer adopt when you resize the window).
This method cannot be called on an instance of ViewState without an Instance assigned. You can use this method on all view states returned by Instance#viewState and Instance#setViewState.
When the new zoom level would exceed the maximum zoom level, it will be capped at the maximum value.
Creates a new ViewState with a specific zoom level that is 25% lower than the current zoom level.
If a ZoomMode is set, it will overwrite it with a number value (which will no longer adopt when you resize the window).
This method cannot be called on an instance of ViewState without an Instance assigned. You can use this method on all view states returned by Instance#viewState and Instance#setViewState.
When the new zoom level would undercut the minimum zoom level, it will be capped at the minimum value.

This flag controls whether a selected tool should maintain its selected state after an annotation is created
- When set to
false, (default), after an annotation has been created the tool is not selected anymore. - When set to
true, the tool used to create the annotation will still be selected and so it'll be possible to keep adding annotations.
This feature is available for Note Annotation, Text Annotation, Redaction Annotation, Shape Annotation and Comments. Ink Annotation behaves like this by default, the ink tool stays selected until its deselected either programmatically or via the UI.
Example
instance.setViewState(viewState => (
viewState.set("keepSelectedTool", true)
));Default Value
false- When set to
layoutMode: "AUTO" | "SINGLE" | "DOUBLE"
Controls how pages inside a view are displayed.
Default Value
pageCursor: unknown
Configuration for cursor behavior keyed by input modality.
The
keyboardproperty is a function that receives the current InteractionMode and returns configuration for that mode. This allows per-mode configuration.Supported InteractionModes for Keyboard Creation
When keyboard returns

- SHAPE_LINE, SHAPE_RECTANGLE, SHAPE_ELLIPSE - 2 point placement
- SHAPE_POLYGON, SHAPE_POLYLINE - multi-point (Shift+Enter to complete)
Example
// Disable keyboard for all modes
instance.setViewState(viewState => (
viewState.set("pageCursor", { keyboard: () => ({ enabled: false }) })
));// Disable keyboard only for INK mode
instance.setViewState(viewState => (
viewState.set("pageCursor", {
keyboard: (mode) => ({ enabled: mode !== InteractionMode.INK })
})
));Default Value
{ keyboard: () => ({ enabled: true }) }pageSpacing: number
The spacing between pages in pixels. This value will adjust to the current zoom level, so when you zoom in, it does not appear fixed to the viewport. This spacing only applies for LayoutMode.DOUBLE.
Default Value
0pagesRotation: 0 | 90 | 180 | 270
The current rotation of all pages. The value is in degrees and describes a clockwise rotation.
Can either be 0°, 90°, 180°, or 270°. Negative values and values above 270 are normalized to one of the valid rotations.
When a page rotation is set, the values are not persisted in the PDF. This setting only affects how the PDF is viewed in the application.
Example
instance.setViewState(viewState => viewState.set("pagesRotation", -450))
// ... later
instance.viewState.pagesRotation; // => 270Default Value
0prerenderedPageSpreads: number | null
Number of page spreads to prerender.
Apart from the current page, Nutrient Web SDK prerenders a specific number of page spreads before and after the current page to improve the user experience when scrolling through the document.
A page spread is a container for either one or two pages, based on the configured layout mode. The number of prerendered page spreads is set to 5 by default, which means that Nutrient Web SDK will prerender 5 page spreads before and after the current page.
If set to
null, all the page spreads in the document will be prerendered. This setting is not recommended for large documents, as it may lead to performance issues.Example
// Prerender 10 page spreads
instance.setViewState(viewState =>
viewState.set("prerenderedPageSpreads", 10)
);
// Prerender all page spreads
instance.setViewState(viewState =>
viewState.set("prerenderedPageSpreads", null)

Default Value
truecanScrollWhileDrawing: boolean
This flag controls whether to enable/disable finger scrolling during Ink Drawing and Ink Erasing using a pen.
- When set to
false, (default), scrolling with the finger in drawing mode is disabled. - When set to
true, once a pen input has been detected, finger input will result in scrolling the document. The pen detection state is shared across all pages, so switching pages does not reset the behavior.
Example
instance.setViewState(viewState => (
viewState.set("canScrollWhileDrawing", true)
));Default Value
false- When set to
commentDisplay: "FITTING" | "POPOVER" | "FLOATING"
Controls how comments are displayed in the viewer in desktop and tablet modes. In mobile devices, comments are always displayed in a drawer a the bottom of the viewport:
- NutrientViewer.CommentDisplay.FITTING: Comments are displayed in a dialog or floating depending on the available viewport space. This is the default value.
- NutrientViewer.CommentDisplay.POPOVER: Comments are displayed in a dialog next to their reference annotation marker.
- NutrientViewer.CommentDisplay.FLOATING: Comments are displayed floating next to the page side, at the same height as their reference annotation marker, except when ViewState#zoom is set to .ZoomeMode#FIT_TO_WIDTH`, in which case they are displayed in a popover dialog instead.
Default Value
currentPageIndex: number
The page index of the page that's currently visible. If there is more than one page visible this will return the page that is using the most space in the viewport. The
pageIndexis zero-based and has a maximum value oftotalPageCount - 1.Default Value

viewState.set("interactionMode", NutrientViewer.InteractionMode.PAN)
));Default Value
nullkeepFirstSpreadAsSinglePage: boolean
When this is enabled, the first spread will always show a single page, even when LayoutMode.DOUBLE is enabled. This is useful for magazines that want to show a cover page before the regular content starts.
A spread is a container for either one or two pages, based on the configured ViewState#layoutMode.
Default Value
falsekeepSelectedTool: boolean
This flag controls whether a selected tool should maintain its selected state after an annotation is created
- When set to
false, (default), after an annotation has been created the tool is not selected anymore. - When set to
true, the tool used to create the annotation will still be selected and so it'll be possible to keep adding annotations.
This feature is available for Note Annotation, Text Annotation, Redaction Annotation, Shape Annotation and Comments. Ink Annotation behaves like this by default, the ink tool stays selected until its deselected either programmatically or via the UI.
Example
instance.setViewState(viewState => (
viewState.set("keepSelectedTool", true)

This allows per-mode configuration (e.g., disable keyboard for some modes).
pageSpacing: number
The spacing between pages in pixels. This value will adjust to the current zoom level, so when you zoom in, it does not appear fixed to the viewport. This spacing only applies for LayoutMode.DOUBLE.
Default Value
0pagesRotation: 0 | 90 | 180 | 270
The current rotation of all pages. The value is in degrees and describes a clockwise rotation.
Can either be 0°, 90°, 180°, or 270°. Negative values and values above 270 are normalized to one of the valid rotations.
When a page rotation is set, the values are not persisted in the PDF. This setting only affects how the PDF is viewed in the application.
Example
instance.setViewState(viewState => viewState.set("pagesRotation", -450))
// ... later
instance.viewState.pagesRotation; // => 270Default Value
0prerenderedPageSpreads: number | null
Number of page spreads to prerender.
Apart from the current page, Nutrient Web SDK prerenders a specific number of page spreads before and after the current page to improve the user experience when scrolling through the document.
A page spread is a container for either one or two pages, based on the configured layout mode. The number of prerendered page spreads is set to 5 by default, which means that Nutrient Web SDK will prerender 5 page spreads before and after the current page.
If set to
null, all the page spreads in the document will be prerendered. This setting is not recommended for large documents, as it may lead to performance issues.Example
// Prerender 10 page spreads
instance.setViewState(viewState =>
viewState.set("prerenderedPageSpreads", 10)
);
// Prerender all page spreads
instance.setViewState(viewState =>
viewState.set("prerenderedPageSpreads", null)
);Default Value
5previewRedactionMode: boolean
This flag controls whether to show the marked state or redacted state for redaction annotations.
- When set to
false, (default), the marked state of redaction annotations will be shown. - When set to
true, the redacted state of redaction annotations will be used.
This flag can only be set to
trueif the Redactions component is included in the license.Example
instance.setViewState(viewState => (
viewState.set("previewRedactionMode", true)
));Default Value
false- When set to
readOnly: boolean
When the read only mode is activated, the UI for creating, updating and deleting annotations will be completely hidden. In addition, the user will also no longer be able to select annotations or modify form field values.
However, it is still possible to add annotations programmatically.
If a read only mode is specified within the JWT itself or in the PDF document permissions, and NutrientViewer.Options.IGNORE_DOCUMENT_PERMISSIONS is not set, this option cannot be unset.
Default Value
falseresolvedLayoutMode: "AUTO" | "SINGLE" | "DOUBLE"
When in LayoutMode.AUTO mode, this property is set to the actual rendered layout mode, which can either be LayoutMode.SINGLE or LayoutMode.DOUBLE. It can be used to be notified when the layout mode changes while still being in LayoutMode.AUTO mode: if the rendered layout mode changes while in NutrientViewer.LayoutMode.AUTO (because of user UI interactions, for example), the viewState.change event will be dispatched, and this property will hold the updated value.
Example
instance.addEventListener("viewState.change", (viewState) => {
console.log(viewState.resolvedLayoutMode);
});scrollMode: "CONTINUOUS" | "PER_SPREAD" | "DISABLED"
Controls how pages can be scrolled.
Default Value
showAIAssistant: boolean
When this is enabled, the AI Assistant chat dialog will be shown. If this is disabled, the chat dialog will not be shown.
Example

trueshowComments: boolean
When this is set to false, comments will no longer be rendered.
NutrientViewer ignores this value when you haven't purchased the comments component.
Default Value
trueshowSignatureValidationStatus: "IF_SIGNED" | "HAS_WARNINGS" | "HAS_ERRORS" | "NEVER"
Controls when the digital signature validation UI will be shown.
Example
instance.setViewState(viewState => (
viewState.set("showSignatureValidationStatus", NutrientViewer.ShowSignatureValidationStatusMode.IF_SIGNED)
));Default Value

| "CUSTOM"
| "FIT_TO_WIDTH"
| "FIT_TO_VIEWPORT"Controls the current zoom factor. This could either be a number multiplier or a ZoomConfiguration or a ZoomMode.
If a number value is used, it must be between Instance#minimumZoomLevel and Instance#maximumZoomLevel.
Note: Using a ZoomMode} will override the padding set using ViewState#viewportPadding
Default Value
{
* zoomMode: NutrientViewer.ZoomMode.AUTO,
* wheelZoomMode: NutrientViewer.WheelZoomMode.WITH_CTRL,
* options: {
* enableKeyboardZoom: true,
* enableGestureZoom: true,

The
ViewStateholds information about the current UI representation of a specific document.It is an Immutable.Record and thus can be updated using
set(key, value), for example:viewState.set("showToolbar", false).An initial
ViewStatecan be set in Configuration.Because the
ViewStateis an immutable data type, you must use Instance#setViewState on the Instance to update it.To be notified when NutrientViewer updates the
ViewState, you can use the dedicated "viewState.change".The following examples show you how to update the
ViewStateand how to get notified aboutViewStatechanges:
