This sample code shows adding Links to PDF document using PDF Cloud Go SDK


    package main

    import (
        "fmt"

        asposepdfcloud "github.com/aspose-pdf-cloud/aspose-pdf-cloud-go/v25"
    )

    func appendLink(pdf_api *asposepdfcloud.PdfApiService, document string, output_document string, page_num int32, link_action string, rect *asposepdfcloud.Rectangle, remote_folder string) {
        uploadFile(pdf_api, document)

        args := map[string]interface{}{
            "folder": remote_folder,
        }

        link := asposepdfcloud.Link{Href: link_action}

        link_annotation := asposepdfcloud.LinkAnnotation{
            Links:        []asposepdfcloud.Link{link},
            ActionType:   asposepdfcloud.LinkActionTypeGoToURIAction,
            Action:       link_action,
            Highlighting: asposepdfcloud.LinkHighlightingModeInvert,
            Color:        &asposepdfcloud.Color{A: 0xFF, R: 0xAA, G: 0x00, B: 0x00},
            Rect:         rect,
        }

        result, httpResponse, err := pdf_api.PostPageLinkAnnotations(
            document, page_num, []asposepdfcloud.LinkAnnotation{link_annotation}, args,
        )
        if err != nil {
            fmt.Println(err.Error())
        } else if httpResponse.StatusCode < 200 || httpResponse.StatusCode > 299 {
            fmt.Println("Unexpected error!")
        } else {
            fmt.Println(result)

            downloadFile(pdf_api, document, output_document)
        }
    }
