GDAL Community,
My application generates a geospatial PDF file from a pre-loaded image source.
When generating an image, I keep receiving an exception of:
"exception class EInvalidOp with message 'Invalid floating point operation'".
I am using the respoitory from 11-20-2012. I am using Borland C compiler (now
known as Embarcadero Codegear).
For Borland, I found a solution at
http://digital.ni.com/public.nsf/allkb/10096EA5DC20FC158625773800628E8A that
quited the Invalid floating point operation, but I still get an exception.
Finally, I built a simple command line program in MSVC 2005 to step through
GDAL source code to find the exception.
The exception occurs when using DEFLATE compression option. The output message
I get is located in trees.c (frmts\zlib) from gen_bitlen(s,desc) function lines
532-559. Zlib is used in pdfcreatecopy.cpp Lines 3496-3501 and 3548. Line
3548 is where it calls VSIFWriteL().
The output string received is:
"bit length overflow
code 0 bits 6->7"
or
"bit length overflow
code 6 bits 6->7
code 0 bits 6->7"
The code and bits are not always the same. For me, it did not matter which
file I used, it always gave me an overflow notice.
Can anyone or has anyone experienced this issue? The file still generates but
my application is halted and a message is presented of the exception.
Robert
