Re: PDFBox 3.0.1 / RandomAccessReadBuffer bug?

[Andreas Lehmkühler]

Hi David,

thanks for the bug report. You are right and the proposed solution seems 
to be a valid fix.


I've created https://issues.apache.org/jira/browse/PDFBOX-5764 to handle it.

Hello

  


I think that this is not correct in some cases:

  


   public RandomAccessReadBuffer(ByteBuffer input) {

 chunkSize = input.capacity();

  


IMHO input.limit() shoud be used instead of input.capacity().

  


When it matters: I have a ByteArrayOutputStream to that is written a PDF
document. Later I want to open the PDF document using PDFBox again. If I use
part of the internal buffer directly (without copying), eg.
ByteBuffer.wrap(bos.getInternalBuffer(), 0, bos.size()), I get exception
like that:

  


java.lang.IllegalArgumentException: newPosition > limit: (31556 > 20960)

31556 is the buffer capacity, 20960 is its limit

  


I think the buffer should not be read beyond its limit.

   Thanks, I applied your changes in the trunk and in 3.0 with some small 
modifications: only one IOException in the javadoc; some grammar changes. If 
I'm right about these, then it proves you were not using an AI, which is a good 
thing.

Re: [PR] Use computed font height as font size [pdfbox]

[via GitHub]

THausherr commented on PR #183:
URL: https://github.com/apache/pdfbox/pull/183#issuecomment-1931495503

   I committed a modified code that only checks for infinity because 1) it's 
more clear, 2) the method still returns a negative font size if the vertical 
size is negative, however this has no bad effect. I also added a test. Thanks 
for the report!
