spv - Simple PIC Viewers
------------------------

Overview
--------

A couple of freely distributable PIC viewers.

vspv -	Very Simple Pic Viewer

qspv -	Quite Simple Pic Viewer
	Quintessentially Slick Pic Viewer

These can view pics of virtually any size. Both require PTR_GEN, qspv
requires WMAN and MENU_REXT. (but you can use qspv with a file name
from the command line without MENU_REXT).

Usage
-----

ex vspv;'filename'

This program can view mode 4 and mode 8 pics. The screen will
temporarily switch mode if necessary (and the O/S supports the mode).

The following keys are recognised.

arrow and shifted arrow keys:
	scroll/pan by 10% of window dimension

ALT+arrow:
	scroll/pan by 80% of window dimension

ESC:
	Exit program


ex qspv;'[-p] filename'

This program can only view mode 4 pics. Attempting to view mode 8 or
mode 2 results in program exit. The PIC can be scrolled/panned using
the scroll/pan bars, or with the mouse.

The following keys are recognised.

shifted arrow keys:
	scroll/pan by 10% of window dimension

ALT+arrow:
	scroll/pan by 80% of window dimension

ESC:
	Exit program

F3:
	Menu (FILE SELECT) to select a PIC file.

Normal Pointer move/size/sleep keys. Tab/Shift Tab moves the pointer
to and from the scroll/pan bars.

Holding down the left mouse button (HIT) and moving the mouse
(left-drag) in the picture window will scroll/pan the image. Holding
down the right mouse button (DO) and moving the mouse (right-drag)
will scroll/pan with a coarser resolution.
 
The option '-p' causes the window to appear at the pointer rather than
centred.

It is possible to 'Config' the program to determine if the menu bar
appears in green/white (colour) or black/white (mono).

Source code
-----------

The source code is provided (unless it's the gs archive). For c68
v4.14 you need iop_svpw_s and libhotthg_a; hopefully these are fixed
in later versions. You need libmin_a for both.
