- comment on CharLS patch (included version, contrary to system CharLS 1.1, grows...

[packages/dcmtk.git] / CharLS.patch

NOTE: system CharLS doesn't dynamically grow output buffer; but the calls below have
buffers allocated for uncompressed_size+1024 bytes, so it's unlikely compressed data
won't fit (if so, CharLS throws exception).
