new DicomWriter()
DICOM writer.
Example usage: var parser = new dwv.dicom.DicomParser(); parser.parse(this.response);
var writer = new dwv.dicom.DicomWriter(parser.getRawDicomElements()); var blob = new Blob([writer.getBuffer()], {type: 'application/dicom'});
var element = document.getElementById("download"); element.href = URL.createObjectURL(blob); element.download = "anonym.dcm";

anonymisationRules
Example anonymisation rules.
- Source
rules
Public (modifiable) rules. Set of objects as: name : { action: 'actionName', value: 'optionalValue } The names are either 'default', tagName or groupName. Each DICOM element will be checked to see if a rule is applicable. First checked by tagName and then by groupName, if nothing is found the default rule is applied.
