John Hewson closed PDFBOX-2663.
-------------------------------
Resolution: Won't Fix
Fix Version/s: (was: 1.8.8)
CID fonts are broken in various other ways in 1.8, so there's not a lot of
point fixing this as it works in 2.0.
> CMap handling bug
> -----------------
>
> Key: PDFBOX-2663
> URL: https://issues.apache.org/jira/browse/PDFBOX-2663
> Project: PDFBox
> Issue Type: Bug
> Components: FontBox
> Affects Versions: 1.8.8
> Environment: Windows 7
> Reporter: Matthew GAO
> Assignee: John Hewson
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Some CMap includes another CMap using the "usecmap" command in the CMap
> resource file. For example, "ETenms-B5-H" includes "ETen-B5-H" CMap. The
> command in resource file is "/ETen-B5-H usecmap"
> The CMapParser does handle this case. Please find the coding below:
> {code}
> if (op.op.equals(USECMAP))
> {
> LiteralName useCmapName = (LiteralName) previousToken;
> InputStream useStream = ResourceLoader.loadResource(resourceRoot +
> useCmapName.name);
> if (useStream == null)
> {
> throw new IOException("Error: Could not find referenced cmap stream "
> + useCmapName.name);
> }
> CMap useCMap = parse(resourceRoot, useStream);
> result.useCmap(useCMap);
> }
> But the useCmap method of CMap class doesn't copy the cidRanges list from the
> child CMap. Please find the coding below:
> public void useCmap( CMap cmap )
> {
> this.codeSpaceRanges.addAll( cmap.codeSpaceRanges );
> this.singleByteMappings.putAll( cmap.singleByteMappings );
> this.doubleByteMappings.putAll( cmap.doubleByteMappings );
> }
> {code}
> Without the cidRanges from the included CMap, PDFBox doesn't know a text can
> be solved by the CMap and return "?" finally.
> Suggest to add the following coding to useCmap method of CMap class to solve
> the problem.
> this.cidRanges.addAll( cmap.cidRanges);
