Package: liblept4 Version: 1.72-3 Severity: normal Dear Maintainer,
liblept4 fails to read any JPEG 2000 file (Jessie) or uses an inefficient temporary file (1.72-3). Example output with tesseract + liblept4 1.71-*: $ tesseract test.jp2 test -l deu-frak hocr Tesseract Open Source OCR Engine v3.05.00dev with Leptonica Warning in fgetJp2kResolution: image resolution not found tesseract: /home/nirgal/openjpeg2-2.1.0/src/lib/openjp2/cio.c:553: opj_stream_get_number_byte_left: Assertion `p_stream->m_user_data_length >= (OPJ_UINT64)p_stream->m_byte_offset' failed. Example output with tesseract + liblept4 1.72-*: $ tesseract test.jp2 test -l deu-frak hocr Tesseract Open Source OCR Engine v3.05.00dev with Leptonica Warning in pixReadMemJp2k: work-around: writing to a temp file ... Example output with tesseract + liblept4 (fixed): $ tesseract test.jp2 test -l deu-frak hocr Tesseract Open Source OCR Engine v3.05.00dev with Leptonica Info in pixReadStreamJp2k: w = 10032, h = 7280, bps = 8, spp = 1 ...
