|
|
<P>A TGI driver for the standard graphics mode (160×102 in 16 colors) is
|
|
available, but must be statically linked, because no file I/O is available.
|
|
See the documentation for the
|
|
<A HREF="co65.html">co65 utility</A>
|
|
for information on how to do that.</P>
|
|
<P>The TGI driver is implemented as a dual buffering device. To use it as a
|
|
single-buffer device set draw page and view page to the same value 0 or 1;</P>
|
|
<P>The TGI driver has a few Lynx-specific extensions.</P>
|
|
<P>Calling tgi_ioctl(0, spr) will display a standard Lynx sprite on screen.</P>
|
|
<P>Calling tgi_ioctl(1, 0) will do a flip screen. If you decide to flip the
|
|
screen then it may be a good idea to call the install-routine for the
|
|
joystick to get that flipped too.</P>
|
|
<P>Calling tgi_ioctl(2, bgindex) will set the text background color to the index
|
|
defined by bgindex. If bgindex is 0 then the background color is transparent.</P>

<P>A joystick driver for the standard buttons is available, but must be

|
statically linked, because no file I/O is available. See the documentation for

|
the

|
<A HREF="co65.html">co65 utility</A> for information on how to do
|
|
that.</P>
|
|
<P>The joystick will check to see if the screen is flipped or not in the install
|
|
routine and adapt itself to the currect state.</P>
