+_Flatten a PDF-file._
+
+```js
+function AsposePdfFlatten(
+    fileBlob,
+    fileName,
+    fileNameResult 
+)
+```
+
+**Parameters**: 
+
+* **fileBlob** Blob object 
+* **fileName** file name 
+* **fileNameResult** result file name 
+
+**Return**: 
+JSON object 
+  * **errorCode** - code error (0 no error)
+  * **errorText** - text error ("" no error)
+  * **fileNameResult** - result file name
+
+
+**Web Worker example**:
+```js
