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

|
39 <UL> |
|
40 <LI>support was added for building the library as a DSO under HP-UX with |
|
41 the native C compiler |
|
42 <LI>tools are now built with explicit pathnames for the DSO under IRIX, |
|
43 Solaris, and Linux |
|
44 <LI>DSO configuration support for Linux was changed to require that |
|
45 <B>libc.so</B> only be readable (not executable) |
|

52 <UL> |
|
53 <LI>support was add for ICC: <TT>NumberOfInks</TT>, and <TT>ICCProfile</TT> |
|
54 <LI>a memory leak caused by doing <TT>TIFFSetDirectory(0)</TT> was fixed |
|
55 <LI>a bug was fixed whereby certain multi-directory files were not |
|
56 properly handled when accessed by mapping the data into memory |
|
57 <LI>the strip chopping support is now always compiled |
|
58 into the library with the default usage controlled by a |
|
59 <TT>STRIPCHOP_DEFAULT</TT> configuration parameter |
|
60 <LI>the strip chopping support no longer chops tiled images |
|
61 <LI>all static strings are now const--for shared libraries |
|
62 <LI>the logic for estimating the strip size of images without |
|
63 a <TT>StripByteCounts</TT> tag was improved by handling |
|
64 <TT>PlanarContig</TT> images differently from <TT>PlanarSeparate</TT> |
|
65 <LI>a bug was fixed in the G3 codec when converting the Y resolution |
|
66 of data specified in metric units |
|
67 <LI>a bug was fixed in the G3/G4 decoder for data where lines terminate |
|
68 with a v0 code |
|
69 <LI>the <TT>TIFFRGBAImage</TT> support was changed to scale 16-bit colormap |
|
70 entries more conservatively to avoid problems with applications |
|
71 that do not generate fully saturated pixel values |
|
72 <LI>the LZW decoder was changed to use a more conservative scheme when |
|
73 bounds checking the hash table array; this avoids pitfalls with |
|
74 systems that load objects into memory in unusual locations |
|
75 <LI>a bug was fixed in <TT>TIFFPrintDirectory</TT>'s handling of the |
|
76 <TT>InkNames</TT> tag |
|
77 <LI><TT>TIFFPrintDirectory</TT> now understands <TT>NumberOfInks</TT> |
|
78 and ICC-related tags |
|
79 <LI>the routines for reading image data now provide more useful information |
|
80 when a read error is encountered |
|
81 <LI>support was added for compiling with Microsoft Visual C++ 4.0 |
|

|
88 <UL> |
|
89 <LI>a bug was fixed in <B>pal2rgb</B>'s colormap handling |
|
90 <LI><B>tiff2ps</B> now includes John Wehle's changes for maintaining |
|
91 the aspect ratio |
|
92 of images when scaling and for honoring the deadzone on a page when |
|
93 generating PostScript Level II |
|
94 <LI><B>tiff2ps</B> does a better job guarding against the mishandling |
|
95 of greyscale images |
|
96 <LI><B>tiff2ps</B> now correctly converts X- and Y-resolution values |
|
97 specified in metric units |
|
98 <LI><B>tiffdump</B> has a new <TT>-m</TT> option to control the maximum |
|
99 number of indirect |
|
100 data values printed for a tag (by default 24) |
|
101 <LI><B>tiffdump</B> understands several new tags |
|
102 <LI><B>tiffdump</B> now shows any terminating null in ASCII strings |
|
103 <LI><B>tiffinfo</B> now suppresses strip chopping when interpreting an image; |
|
104 a new <TT>-z</TT> option has been added to enable strip chopping |
