This document describes the changes made to the software between the | |
<I>previous</I> and <I>current</I> versions (see above). | |
If you don't find something listed here, then it was not done in this | |
timeframe, or it was not considered important enough to be mentioned. | |

<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A> | |
<UL> | |
<LI>support was added for building the library as a DSO under HP-UX with | |
the native C compiler | |
<LI>tools are now built with explicit pathnames for the DSO under IRIX, | |
Solaris, and Linux | |
<LI>DSO configuration support for Linux was changed to require that | |
<B>libc.so</B> only be readable (not executable) | |
</UL> | |
<P><HR WIDTH=65% ALIGN=right> | |
<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A> | |
<UL> | |
<LI>support was add for ICC: <TT>NumberOfInks</TT>, and <TT>ICCProfile</TT> | |
<LI>a memory leak caused by doing <TT>TIFFSetDirectory(0)</TT> was fixed | |
<LI>a bug was fixed whereby certain multi-directory files were not | |
properly handled when accessed by mapping the data into memory | |
<LI>the strip chopping support is now always compiled | |
into the library with the default usage controlled by a | |
<TT>STRIPCHOP_DEFAULT</TT> configuration parameter | |
<LI>the strip chopping support no longer chops tiled images | |
<LI>all static strings are now const--for shared libraries | |
<LI>the logic for estimating the strip size of images without | |
a <TT>StripByteCounts</TT> tag was improved by handling | |
<TT>PlanarContig</TT> images differently from <TT>PlanarSeparate</TT> | |
<LI>a bug was fixed in the G3 codec when converting the Y resolution | |
of data specified in metric units | |
<LI>a bug was fixed in the G3/G4 decoder for data where lines terminate | |
with a v0 code | |
<LI>the <TT>TIFFRGBAImage</TT> support was changed to scale 16-bit colormap | |
entries more conservatively to avoid problems with applications | |
that do not generate fully saturated pixel values | |
<LI>the LZW decoder was changed to use a more conservative scheme when | |
bounds checking the hash table array; this avoids pitfalls with | |
systems that load objects into memory in unusual locations | |
<LI>a bug was fixed in <TT>TIFFPrintDirectory</TT>'s handling of the | |
<TT>InkNames</TT> tag | |
<LI><TT>TIFFPrintDirectory</TT> now understands <TT>NumberOfInks</TT> | |
and ICC-related tags | |
<LI>the routines for reading image data now provide more useful information | |
when a read error is encountered | |
<LI>support was added for compiling with Microsoft Visual C++ 4.0 | |
</UL> | |
<P><HR WIDTH=65% ALIGN=right> | |
<A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A> | |
<UL> | |
<LI>a bug was fixed in <B>pal2rgb</B>'s colormap handling | |
<LI><B>tiff2ps</B> now includes John Wehle's changes for maintaining | |
the aspect ratio | |
of images when scaling and for honoring the deadzone on a page when | |
generating PostScript Level II | |
<LI><B>tiff2ps</B> does a better job guarding against the mishandling | |
of greyscale images | |
<LI><B>tiff2ps</B> now correctly converts X- and Y-resolution values | |
specified in metric units | |
<LI><B>tiffdump</B> has a new <TT>-m</TT> option to control the maximum | |
number of indirect | |
data values printed for a tag (by default 24) | |
<LI><B>tiffdump</B> understands several new tags | |
<LI><B>tiffdump</B> now shows any terminating null in ASCII strings | |
<LI><B>tiffinfo</B> now suppresses strip chopping when interpreting an image; | |
a new <TT>-z</TT> option has been added to enable strip chopping | |
</UL> | |
