Highlight text programatically

[dinchu]

is possible to highlight text passed programatically when the pdf is loaded?

@dinchu I've been trying to make this work as well. If you know exact coordinates of the text you could create a text highlight with the annotation plugin. However, in my case I don't, I just have the exact text. There does not seem an official way to do it based on pure text match, however, you could combine search and annotation plugins to achieve this, not in a clean way... but possible.

const { provides: search, state: searchState } = useSearch(documentId)
const { provides: annotation, state: annotationState } = useAnnotation(documentId)
....
 // I did not find a way to scope search to just one page, however, search results can be filtered later.
 const matches = await search
        .searchAllPages('Text to match')
        .toPromise()
 
 const matchesPerPage = matches.filter(match => match.pageIndex === highlightPageIndex)
 for (const match of matchesPerPage) {
    annotation.createAnnotation(highlightPageIndex, { 
          type: PdfAnnotationSubtype.HIGHLIGHT, 
          segmentRects: match.rects, 
          //...other properties
     }) 
 }
