Steps to replace annotations using Go
Aspose.PDF Cloud Go developers can easily replace annotations in PDF documents. Developers need just a few lines of code.
- Uploading the file to cloud storage.
- getAnnotation fetches a text annotation by ID from a PDF stored in the cloud.
- ModifyAnnotation updates the contents and icon of that annotation.
- After modification, the updated PDF is downloaded locally.
This sample code shows replacing Text Annotations in PDF document using PDF Cloud Go SDK
package main
import (
"fmt"
asposepdfcloud "github.com/aspose-pdf-cloud/aspose-pdf-cloud-go/v25"
)
func getAnnotation(pdf_api *asposepdfcloud.PdfApiService, document_name string, annotation_id string, remote_folder string) *asposepdfcloud.TextAnnotation {
// Get annotation by Id in the PDF document.
args := map[string]interface{}{
"folder": remote_folder,
}
result, httpResponse, err := pdf_api.GetTextAnnotation(document_name, annotation_id, args)
if err != nil {
fmt.Println(err.Error())
return nil
} else if httpResponse.StatusCode < 200 || httpResponse.StatusCode > 299 {
fmt.Println("getAnnotation(): Failed to get annotation in the document.")
return nil
} else {
fmt.Println("getAnnotation(): nnotation '" + annotation_id + "' successfully found '" + result.Annotation.Contents + "' in the document '" + document_name + "'.")
return result.Annotation
}
}
func ModifyAnnotation(pdf_api *asposepdfcloud.PdfApiService, document_name string, output_document string, annotation_id string, remote_folder string) {
// Change annotation by Id in the PDF document.
UploadFile(pdf_api, document_name)
args := map[string]interface{}{
"folder": remote_folder,
}
annotation := getAnnotation(pdf_api, document_name, annotation_id, remote_folder)
annotation.Contents = REPLACED_CONTENT
annotation.Icon = asposepdfcloud.TextIconStar
_, httpResponse, err := pdf_api.PutTextAnnotation(document_name, annotation_id, *annotation, args)
if err != nil {
fmt.Println(err.Error())
} else if httpResponse.StatusCode < 200 || httpResponse.StatusCode > 299 {
fmt.Println("ModifyAnnotation(): Failed to modify annotation in the document.")
} else {
fmt.Println("ModifyAnnotation(): annotation '" + annotation.Id + "' successfully modified in the document '" + document_name + "'.")
DownloadFile(pdf_api, document_name, output_document, "replaced_annotatiom_")
}
}
