Q: When opening a PDF file, I get the following error:

cmap_error
Error Rendering Page Invalid CMAP name: KSCms-UHC-H

A: You are missing cmaps.jar in your classpath which contains CMaps, used to read and display character encodings used with CJK (Chinese, Japanese, Korean) content.

Download cmaps.jar

 

This error can happen when rendering PDF documents in Qoppa’s PDF components (jPDFViewer, jPDFNotes, jPDFEditor) or printing PDF documents using Qoppa’s PDF libraries (jPDFProcess or jPDFPrint) or converting PDF documents to images using Qoppa’s PDF libraries (jPDFImages, jPDFProcess).
