Tilman Hausherr commented on PDFBOX-4763:
-----------------------------------------
Code from PDStream.java:
{code:java}
public InputStream createInputStream(List<String> stopFilters) throws
IOException
{
InputStream is = stream.createRawInputStream();
ByteArrayOutputStream os = new ByteArrayOutputStream();
List<COSName> filters = getFilters();
if (filters != null)
{
for (int i = 0; i < filters.size(); i++)
{
COSName nextFilter = filters.get(i);
if ((stopFilters != null) &&
stopFilters.contains(nextFilter.getName()))
{
break;
}
else
{
Filter filter = FilterFactory.INSTANCE.getFilter(nextFilter);
filter.decode(is, os, stream, i);
IOUtils.closeQuietly(is);
is = new ByteArrayInputStream(os.toByteArray());
os.reset();
}
}
}
return is;
}{code}
I think we should just change the last line in the PDInlineImage.java method to
"return in".
> Can't get inline image raw data
> -------------------------------
>
> Key: PDFBOX-4763
> URL: https://issues.apache.org/jira/browse/PDFBOX-4763
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 2.0.15
> Reporter: Constantine Dokolas
> Priority: Minor
>
> I'm trying to "clone" an inline image (having the original {{PDInlineImage}}
> object) and I can't find a way to access the raw image data. The reason I
> want the raw data is because I'm copying the dictionary as it is, including
> the filters, and using the {{PDInlineImage}} constructor (not going via a
> {{BufferdImage}} and {{LosslessFactory}}).
> It would seem to me that {{createInputStream(List<String> stopFilters)}}
> should return the un-decoded stream when provided with a list blocking all
> filters, but all it returns is an empty stream. The source code suggests that
> {{PDImageXObject}} has the same behavior. This should not be the case. When
> decoding is blocked, the raw data should be returned.
