# loadDocumentTemplateBuffer static method

void loadDocumentTemplateBuffer(

1. Uint8List? buffer

)

Loads a document template from a data buffer.

param buffer A buffer containing the document template data. throws DocumentException An error has occurred during Document Library execution.

## Implementation

    static void loadDocumentTemplateBuffer(Uint8List? buffer) {
      Pointer<UnsignedChar>? pBuffer;
      if (buffer != null) {
      	pBuffer = calloc.allocate<UnsignedChar>(buffer.length);
      	pBuffer.cast<Uint8>().asTypedList(buffer.length).setAll(0, buffer);
      }
      try {
        var err = documentSDK.id3DocumentLibrary_LoadDocumentTemplateBuffer(pBuffer ?? nullptr, buffer?.length ?? 0);
        if (err != DocumentError.success.value) {
          throw DocumentException(err);
        }
      } finally {
        if (pBuffer != null) {
          calloc.free(pBuffer);
        }
      }
    }
