CPDFImageAnnotation.fromJson constructor

CPDFImageAnnotation.fromJson(Map<String, dynamic> json)

Creates an image annotation from serialized JSON data.

Use this to restore annotations returned by ComPDFKit APIs or loaded from a previously persisted payload.

Example:

final annotation = CPDFImageAnnotation.fromJson({
  'type': 'pictures',
  'page': 0,
  'uuid': 'annotation-id',
  'rect': {
    'left': 80.0,
    'top': 120.0,
    'right': 220.0,
    'bottom': 260.0,
  },
  'imageData': {
    'type': 'asset',
    'data': 'assets/images/stamp.png',
  },
});

Implementation

factory CPDFImageAnnotation.fromJson(Map<String, dynamic> json) {
  final common = CPDFAnnotation.fromJson(json);
  final imageDataJson = json['imageData'];
  return CPDFImageAnnotation(
    title: common.title,
    content: common.content,
    createDate: common.createDate,
    page: common.page,
    uuid: common.uuid,
    rect: common.rect,
    image: json['image'],
    imageData: imageDataJson is Map<String, dynamic>
        ? CPDFImageData.fromJson(imageDataJson)
        : imageDataJson is Map
            ? CPDFImageData.fromJson(Map<String, dynamic>.from(imageDataJson))
            : null,
  );
}
