- TIFVIEW & IM_EXPG/IM_PACG Software Description
-
- Thank you for taking the time to look at this demonstration release of our TIF
- viewing and compression software.
-
- This disk contains:
-
- TIFVIEW.EXE - the VGA TIF file viewer for 1 bit per pixel
- TIF images. It will view uncompressed 1 bpp TIFS and G3 & G4 TIFs. To see a
- usage message, type TIFVIEW and press<ENTER>. The viewer uses a mouse or keyboard to pan and zoom, or change pages on a multi-page TIF. It will also
- perform 3 types of anti-aliasing by pressing 'A' when viewing in half scale.
-
- IM_PACG - This program will compress 1 bpp uncompressed
- TIF images to CCITT Group 3 & 4 format.
-
- IM_EXPG - This program decompress CCITT Group 3 & 4 format
- TIF files to uncompressed TIF format.
-
- Also included is the TIFFTAGS program which will allow you to determine
- what type of TIFF files you have. This utility comes in handy at PIC, and
- should serve to remind you to call on us for any of your image file
- management needs!
-
-
- The usage statements for the programs follow but the general concept behind
- this software is Black & White (1 bit per pixel) image viewing and
- compression programs that work with uncompressed TIFF and CCITT Group 3 & 4
- files as input for compression.
-
- When using TIFVIEW You should try pressing the 'a' key for text cleanup, 'n'
- for negative view (switches B&W), and '+' and '-' when viewing multi-page
- TIFs. On the command line a '/K' will allow you to reverse image movement.
- (Try it!)
-
- Please call on us with any question, comments, and of course, suggestions for
- improvement.
-
- Thank You

-
- Version 2.10
-
- usage: TIFVIEW tiff_file[.tif] { options }
- where options are:
- /K Key movement's sense is reversed, i.e., up arrow moves image down.
- /N Negate the sense of black and white for the display
- /R Reverse the bitorder for the display (used to correct improperly
- created TIFF files).
- /T Title the display with the file path and name
-
- Scrolling is done by mouse, or by keyboard (cursor left, right, up, down,
- Control cursor right, Control cursor left, Pg Up, Pg Dn, Home, End,
- Control Pg Up, Control Pg Dn)
- Page movement is done using the '+' and '-' keys in order to display the
- next page and prior page.
- Half-scaling of the image is toggled by pressing 'H' or the left mouse button
- Alternate the display of the half-scaled image by toggling 'A'
- Foreground and Background colors are rotated by pressing 'F' and 'B'
- Negative toggles by pressing 'N'
- Initial color setup is restored by pressing 'R'
- Quit by right mouse button, or pressing Enter, Escape, 'Q', 'X', or 'E'
-
- If what you see when you press return is garbage, try reading the file again
- with the Reverse option set (/R on the command line). Often TIFF files have
- this tag incorrectly specified.
-
- IMEXPG source[.tif] destination[.tif] { options }
-
- options are:
- /R - Reverse video (reverse black and white colors)
- /S - Swap bits (make low-order bit the first bit)
- /T - indicate Timing information
-
- IM_PACG source[.tif] destination[.tif] { options }
-
- options are:
- /T2 - create modified group 3 (CCITT T.4, 1-Dimension) image
- /T3 - create group 3 (CCITT T.4, 1-Dimension) image
- /T4 - create group 4 (CCITT T.6) image (default)
-
-
- TIFFTAGS.EXE tiff_file
-
- This program reads a TIFF file and decodes the header information.
- You can optionally pipe the output to a text file ( >info.txt)
- or to the screen (|MORE). We hope TIFFTAGS proves as useful
- to you as it has been for us!
