2TIFF

Version 4.1 (15 May, 2002).
What's new:

• added deffered loading of engine modules to make program load faster;
• fixed error in command line parser;
• fixed error in "-coleff(4;R;G;B)" option (in previous version R and B channels were mixed up);
• fixed error causing program to crash at reading corrupted in PNG files;
• added support of JPEG 2000 format;
• critical code sections are rewritten on MMX to increase productivity;
• fixed bug with option "-sep(n;m)";
• fixed errors with reading of DXF files;
• updated help file;
• added "smart" autodetection of optimal color depth for output file
  (works if "-cd" option s not used).
  Example of working while converting to JPEG file format:
  JPEG file format supports the following color spaces: grayscale (8 bpp), truecolor (24 bpp, 32 bpp).
  Source images:
  - color image with any color depth up to 24 bpp (for instance 8 bit GIF file or 24-bit bitmap) will be converted to 24 bit color JPEG file
  - color image with color depth more then 24 bit per pixel will be converted to 32-bit color JPEG;
  - grayscale or black and white image regardless of its color depth will be converted to 8 bit grayscale JPEG;
  This feature allows to automaticaly get images with optimal ratio of size/color or size/quality;
• fixed error with conversion to TIFF files with LZW compression (in previous version 2TIFF created non compressed files instead of files with LZW compression).

Added the following options:

• -msw
  Many image viewers act as though PhotoMetricInterpritation = MINISWHITE mode is the only possilbe mode for black and white tiff files. That is why they may display files saved in other mode not correctly. If you want your files to be correctly displayed by all viewers, use -msw option. Note that using this option may slow down conversion. If you don't use this option files will be saved in back and white tiff files either in PhotoMetricInterpritation = MINISWHITE mode, or in PhotoMetricInterpritation = MINISBLACK mode, depending on file.
• -storeext
  If this option is used converted files will have the same file extension as source files.
• -imginfo
  If this option is used information about each loaded file - file format, file length (bytes), image width and height (pixels), color depth (bpp), image resolution (dpi) and number of pages - will be displayed in DOS window and recorded in log file.
• -remsrc
  Deletes source files.
• -propfill
  This variation of option -prop stretches images proportionally and fills empty spaces with color specified by -bc option.
• srclst=
  This option allows you to create a list of paths and masks for files you want to convert. You may use it instead of s= option, or together with it. List file may have any name or extention, but must be in text format. Example of list file:

  E:\Graphic Files\in1\*.*
  E:\Graphic Files\in2\*.jpg
  E:\Graphic Files\in3\*.bmp
  E:\Graphic Files\in4\image.gif
