# Release Notes for SMII UNIX API Version 2.0 Beta #
####################################################
February 19th 1996

Major rewrite to incorporate new ScreenMAchine board 
and other ///FAST boards.


New Driver configuration mechanism
==================================
There is now a configure script in the Driver directory.
It will prompt you for the base address and major number 
of the driver. As well as some licensing information. Don't
worry if you don't have a License, just leave them empty, 
it will work with the same limitations as the 1.3 version
did. It will build a new smii_module for you.
It is no longer possible to set the address with the smiiInit
Call. People seemed to confused about the idea that their
progran can set the address at will. 

Bug fixes
=========
Better image scaling when loading images into ScreenMachine.

Just a maintanace release. There where problems loading 
the module into newer kernel versions. This version now 
supports version information of symbols. Make sure the 
option is on when configuring the kernel.
We have it now working under Kernel release 1.2.12.

Bug fixes
=========
Problem with setting NTSC should be fixed.

Enhancements
============
SMUtil
1. The flm2tiff conversion was enhanced. The image quality
   is a lot better now, and the process is also reversible,
   without to significant of a picture quality degradation.
2. flm2tiff now can also handle YUV Mode 1 images.

libtiff.a
3. smReadYImage has been added to allow faster reading of Y
   only (grayscale) images. This call will produce  FLM files
   with YUVMode 1 data. Calling parameters are identical to
   smReadImage. Only half the memory is necessary for Y only
   images. (size = width * height). (There is a smWriteYImage
   but, smWriteImage will handle Mode 1 images as well).
4. smWriteImage now als handles YUV Mode 1 FLM images.

SMParser
5. The parser supports the two new read and write methods with the
   yread and ydisplay commands.

	
Bug fixes
=========
libsm.a
1. Bug in smReadImage that cause at 64 byte offset and could be
   noticed as a 32bit pixel shift in images.
2. Bug that cause horizontal 'stripes' in images when reading or
   writing them. This was due to a bug in port I/O on some machines.
3. Bug in smWriteImage that would scale images incorrectly when 
   smSetHScale was less than 2.



FREE RELEASE
============
The following calls are not supported in the free release:
   * smGetInterlaced
   * smSetInterlaced
   * smGetHScale
   * smSetHScale
