| 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. | |
| 28 | The following information is located here: | |

| 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) | |
| 46 | </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 | |
| 82 | </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 | |
