2018-01-15Correct handling of elf symbol versioningJay Berkenbilt
We were putting the value of LT_CURRENT in the versioned symbol map instead of the soname major version, which was creating binary incompatibility where none was present. Unfortunately, this bug is already out there for qpdf 7.0.0, so we'll have to work around it for now.

2018-01-14Use correct link directory order (fixes #158)Jay Berkenbilt
Make sure to link from the source tree before linking from the system. In many environments, this is necessary to allow a newly built qpdf to link properly instead of trying to link or resolve libraries from an older installed version.

2018-01-14Use better error for getStreamData failureJay Berkenbilt
If the stream isn't filterable but we call getStreamData, throw a regular exception instead of a logic error so that normal error handling and reporting mechanisms will be used.

Tweak the message so that we inform the user that we are mitigating data loss.
2017-09-12Update C API with new QPDFWriter methodsJay Berkenbilt
2017-09-08Pl_DCT: Use custom source and destination managers (fixes #153)Jay Berkenbilt
Avoid calling jpeg_mem_src and jpeg_mem_dest. The custom destination manager writes to the pipeline in smaller chunks to avoid having the whole image in memory at once. The source manager works directly with the Buffer object. Using customer managers avoids use of memory source and destination managers, which are not present in older versions of libjpeg still in use by some Linux distributions.
