| 41 | <LI>bit order was corrected for Pentium systems | |
| 42 | <LI>a new define, <TT>HOST_BIGENDIAN</TT>, was added for code that | |
| 43 | wants to statically use information about native cpu byte order | |

| 51 | <LI>the G3/G4 decoder was replaced by a new one that is faster and | |
| 52 | has smaller state tables | |
| 53 | <LI>Niles Ritter's client tag extension hooks were added | |
| 54 | <LI>a new routine <TT>TIFFCurrentDirOffset</TT> was added for | |
| 55 | applications that want to find out the file offset of a TIFF directory | |
| 56 | <LI>the calculation of the number of strips in an image was corected | |
| 57 | for images with certain esoteric configurations | |
| 58 | <LI>a potential memory leak (very unlikely) was plugged | |
| 59 | <LI>the <TT>TIFFReadRGBAImage</TT> support was completely rewritten | |
| 60 | and new, more flexible support was added for reading images into | |
| 61 | a fixed-format raster | |
| 62 | <LI>YCbCr to RGB conversion done in the <TT>TIFFReadRGBAImage</TT> support | |
| 63 | was optimized | |
| 64 | <LI>a bug in JPEG support calculation of strip size was corrected | |
| 65 | <LI>the LZW decoder was changed to initialize the code table to zero | |
| 66 | to lessen potential problems that arise when invalid data is decoded | |
| 67 | <LI><B>tiffcomp.h</B> is now aware of OS/2 | |
| 68 | <LI>some function prototypes in <B>tiffio.h</B> and <B>tiffiop.h</B> | |
| 69 | that contained parameter | |
| 70 | names have been changed to avoid complaints from certain compilers | |

| 87 | <LI><TT>fax2ps</TT> has been rewritten and moved over from the user | |
| 88 | contributed software | |
| 89 | <LI>an uninitialized variable in <TT>pal2rgb</TT> has been fixed | |
| 90 | <LI><TT>ras2tiff</TT> now converts 24-bit RGB raster data so that | |
| 91 | samples are written in the proper order | |
| 92 | <LI><TT>tiff2ps</TT> has been updated to include fixes | |
| 93 | and enhancements from Alberto Accomazzi | |
| 94 | <LI><TT>tiffcp</TT> now has a <TT>-o</TT> option to select a directory | |
| 95 | by file offset | |
| 96 | <LI><TT>tiffinfo</TT> is now capable of displaying the raw undecoded | |
| 97 | image data in a file | |
| 98 | <LI><TT>tiffgt</TT> has been rewritten to use the new <TT>TIFFRGBAImage</TT> | |
| 99 | support and to handle multiple files | |
