This change was automated via the following command: $ git ls-files | xargs sed -i 's/,qtbase)/,qtbase-5)/g' $ git ls-files | xargs sed -i 's/inherit qtbase)/inherit qtbase-5)/g' $ git ls-files | xargs sed -i 's/package-version qtbase)/package-version qtbase-5)/g' $ git checkout etc # to clear some spurious changes This is done so the qtbase package can be upgraded to version 6 in the following commit.

ISO/IEC 11544:1993), designed for bi-level (one bit per pixel) images such as

black-and-white scanned documents.  It is widely used in fax products, printer

firmware and drivers, document management systems, and imaging software.
 |

 |

This package provides a static C library of (de)compression functions and some
 | 
						||
simple command-line converters similar to those provided by netpbm.
 | 
						||
 | 
						||
Two JBIG1 variants are available.  One (@file{jbig.c}) implements nearly all
 | 
						||
options of the standard but has to keep the full uncompressed image in memory.
 | 
						||
The other (@file{jbig85.c}) implements just the ITU-T T.85 profile, with
 |

memory management optimized for embedded and fax applications.  It buffers

only a few lines of the uncompressed image in memory and is able to stream
