Access annotations
The steps to access a list of annotations and annotation objects are as follows:
- Obtain the page object.
- Access the list of annotations from the page object.
- Iterate through each annotation object in the list.
This example shows how to access annotations:
Java
CPDFDocument document = readerView.getPDFDocument();
int pageCount = document.getPageCount();
if (pageCount > 0){
for (int pageIndex = 0; pageIndex < pageCount; pageIndex++) {
List<CPDFAnnotation> annotations = document.pageAtIndex(pageIndex).getAnnotations();
if (annotations != null && !annotations.isEmpty() ){
for (CPDFAnnotation annotation:annotations){
if (annotation == null || !annotation.isValid()){
continue;
}
// Begin operations on the acquired annotations.
}
}
}
}
kotlin
val document: CPDFDocument = readerView.pdfDocument
val pageCount = document.pageCount
if (pageCount > 0) {
for (pageIndex in 0 until pageCount) {
val annotations = document.pageAtIndex(pageIndex).annotations
if (annotations != null && annotations.isNotEmpty()) {
for (annotation in annotations) {
if (annotation == null || !annotation.isValid) {
continue
}
// Begin operations on the acquired annotations.
}
}
}
}
