Learn how to create, customize, and manage strikeout annotations using web. Explore essential properties and settings for precise text editing. The A Strikeout annotations are annotations that draw a strikeout line through text. Text strikeout annotations use the stroke color as the strikeout color. Setting a fill color will have no visual impact on the annotation by default. ![](https://3532544125-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FX9YnTSKIHvV7m0A36LbO%2Fuploads%2Fgit-blob-a51df80e327a201c78802cb5eb35470b7dde692a%2F61c5b70dc7cce9944fc2cccc8579b86244ef64f7-382x152.png?alt=media) ## Instantiation {% tabs %} {% tab title="JavaScript (SDK v8.0+)" %} {% code lineNumbers="true" %} ```js WebViewer(...) .then(instance => { const { documentViewer, annotationManager, Annotations } = instance.Core; let debounce = null; // Automatically create strikeout annotations on text selection documentViewer.addEventListener('textSelected', (quads, text, pageNumber) => { // Add some debouncing to prevent constant triggering during selection if (debounce) { clearTimeout(debounce); } debounce = setTimeout(() => { // Create annotation with object initializer const annot = new Annotations.TextStrikeoutAnnotation({ PageNumber: pageNumber, Quads: quads, StrokeColor: new Annotations.Color(0, 0, 255, 1), StrokeThickness: 3, }); annotationManager.addAnnotation(annot); annotationManager.redrawAnnotation(annot); debounce = null; }, 1000); }); }); ``` {% endcode %} [DocumentViewer#textSelected](https://sdk.apryse.com/api/web/Core.DocumentViewer.html#event:textSelected) [TextStrikeoutAnnotation](https://sdk.apryse.com/api/web/Core.Annotations.TextStrikeoutAnnotation.html) [Color](https://sdk.apryse.com/api/web/Core.Annotations.Color.html) [AnnotationManager.addAnnotation](https://sdk.apryse.com/api/web/Core.AnnotationManager.html#addAnnotation) [AnnotationManager.redrawAnnotation](https://sdk.apryse.com/api/web/Core.AnnotationManager.html#redrawAnnotation) {% endtab %} {% tab title="JavaScript (SDK v6.0+)" %} {% code lineNumbers="true" %} ```js WebViewer(...) .then(instance => { const { docViewer, annotManager, Annotations } = instance; let debounce = null; // Automatically create strikeout annotations on text selection docViewer.on('textSelected', (quads, text, pageNumber) => { // Add some debouncing to prevent constant triggering during selection if (debounce) { clearTimeout(debounce); } debounce = setTimeout(() => { // Create annotation const annot = new Annotations.TextStrikeoutAnnotation(); annot.PageNumber = pageNumber; annot.Quads = quads; annot.StrokeColor = new Annotations.Color(0, 0, 255, 1); annot.StrokeThickness = 3; annotManager.addAnnotation(annot); annotManager.redrawAnnotation(annot); debounce = null; }, 1000); }); }); ``` {% endcode %} [DocumentViewer#textSelected](https://sdk.apryse.com/api/web/Core.DocumentViewer.html#event:textSelected) [TextStrikeoutAnnotation](https://sdk.apryse.com/api/web/Core.Annotations.TextStrikeoutAnnotation.html) [Color](https://sdk.apryse.com/api/web/Core.Annotations.Color.html) [AnnotationManager.addAnnotation](https://sdk.apryse.com/api/web/Core.AnnotationManager.html#addAnnotation) [AnnotationManager.redrawAnnotation](https://sdk.apryse.com/api/web/Core.AnnotationManager.html#redrawAnnotation) {% endtab %} {% endtabs %} ## XFDF Element name: `strikeout` {% tabs %} {% tab title="Shell" %} {% code lineNumbers="true" %} ```sh ``` {% endcode %} {% endtab %} {% endtabs %} ## Required properties ### PageNumber Gets or sets the page number of a document that the annotation appears on. ### Quads Gets of sets the text quads of the annotation. Since text annotations can span multiple lines of text, the lines of text are represented with an array of quads. ## Notable Properties For the full list of properties, please visit the annotation's [API docs](https://sdk.apryse.com/api/web/Core.Annotations.TextStrikeoutAnnotation.html). ### StrokeColor Gets or sets the color of the annotation's stroke. ### StrokeThickness Gets or sets the width of the annotation's stroke outline. ### Author The author of the annotation. ### Color Gets or sets the annotation's stroke color. ### Hidden Gets or sets whether the annotation is hidden. ### Invisible Gets or sets whether the annotation is invisible, only if it is an unknown annotation type. Generally for hiding annotations you should use "Hidden". ### IsClickableOutsideRect Gets or sets whether any parts of the annotation drawn outside of the rect are clickable. ### Listable Gets or sets whether the annotation should be listed in annotation lists. If set to false, the annotation will also become unselectable. ### Locked Gets or sets whether the annotation is locked or not. If it's locked it can't be edited or deleted, but the note can be edited. ### LockedContents Gets or sets whether the annotation contents are locked or not. If the contents are locked then note can't be edited but the annotation can be edited or deleted. ### NoDelete Gets or sets if this annotation can be deleted. ### NoMove Gets or sets whether or not the annotation can be moved. ### NoResize Gets or sets if this annotation can be resized by the user. ### NoView Gets or sets whether the annotation is visible on the screen. Differs from Hidden in that it can still be printed if the print flag is set. ### Opacity Gets or sets the opacity of the annotation. ### Printable Gets or sets whether the annotation should be displayed when printing the page. ### ReadOnly Gets or sets whether the annotation is readonly or not. If it's readonly both the annotation itself and its note can't be edited or deleted. ### ToggleNoView Gets or sets whether the ToggleNoView flag is set on the annotation. ## Useful methods ### getQuads Although it is possible to get the quads using the `Quads` property, there is also a `getQuads` method on the annotation to get its quads. {% tabs %} {% tab title="Shell" %} {% code lineNumbers="true" %} ```sh console.log(strikeout.getQuads()); [ { // First quad of the first line "x1":58.24, "y1":98.97, "x2":265.13, "y2":98.97, "x3":265.13, "y3":87.47, "x4":58.25, "y4":87.47 }, ... // Second quad of the second line and so on ] ``` {% endcode %} {% endtab %} {% endtabs %} ### setQuads Using the `setQuads` API can be used to set the quads for the annotation as well. {% tabs %} {% tab title="JavaScript (SDK v8.0+)" %} {% code lineNumbers="true" %} ```js WebViewer(...) .then(instance => { const { annotationManager, Annotations } = instance.Core; annotationManager.addEventListener('annotationChanged', (annotations, action) => { if (annotations.length > 0 && action === 'add') { annotations.forEach(annot => { if (annot instanceof Annotations.TextStrikeoutAnnotation) { const quads = annot.getQuads(); quads.forEach(quad => { quad.x1 = Math.round(quad.x1 * 100) / 100; quad.y1 = Math.round(quad.y1 * 100) / 100; }); annot.setQuads(quads); } }); } }); }); ``` {% endcode %} [TextStrikeoutAnnotation.setQuads](https://sdk.apryse.com/api/web/Core.Annotations.TextStrikeoutAnnotation.html#setQuads) {% endtab %} {% tab title="JavaScript (SDK v6.0+)" %} {% code lineNumbers="true" %} ```js WebViewer(...) .then(instance => { const { annotManager, Annotations } = instance; annotManager.on('annotationChanged', (annotations, action) => { if (annotations.length > 0 && action === 'add') { annotations.forEach(annot => { if (annot instanceof Annotations.TextStrikeoutAnnotation) { const quads = annot.getQuads(); quads.forEach(quad => { quad.x1 = Math.round(quad.x1 * 100) / 100; quad.y1 = Math.round(quad.y1 * 100) / 100; }); annot.setQuads(quads); } }); } }); }); ``` {% endcode %} [TextStrikeoutAnnotation.setQuads](https://sdk.apryse.com/api/web/Core.Annotations.TextStrikeoutAnnotation.html#setQuads) {% endtab %} {% endtabs %} --- # Agent Instructions This documentation is published with GitBook.
