INTRODUCTION
This program magnifies an area of the screen and displays it in a seperate
window.
USAGE
This program can be started from Workbench or CLI.
It will try to evaluate the following tooltypes:
CX_PRIORITY : A number between -128 and 127 which set the priority of
the commodity. With that the system decides in which
succession the commodities gets the messages.
The commodity with the highest priority gets the message
first.
Default is 0.
FAST : The window will often redrawn.
Default is NO.
SCALEFACTOR : Default is 5.
MAXSCALEFACTOR : The maximum scalefactor (between 5 and 30)
Default is 15.
COORDINATES : In the bottom border the mouse coordinates will be
displayed.
Default is NO.
CROSSHAIR : A crosshair visualised the position of the mouse.
Default is NO.
FIXED : When this flag is YES/ON the center of the magnified area
was not described by the mouse coordinates but it's fixed
until you clicked into the window.
Now with the holded left mousebutton you can move the area.
Default is NO.
SETORIGINKEY : A hotkey to set an imaginary origin.
Default is 'lalt o'.
RESETORIGINKEY : A hotkey to reset the imaginary origin to 0,0.
Default is 'lalt r'.
SHOWHIDEKEY : A hotkey to open/close the window.
WINLEFT
WINTOP
WINWIDTH
WINHEIGHT : These values describes the position and dimension of the
window.
ICONIFY : The window will not opened.
Default is NO.
ICONIFYONCLOSE : If you press the closebutton the program will not be ending.
Default is NO.
GRID : This turns on the grid.
Default is OFF.
SHOWRGB : In the bottom border the color values will be displayed.
Default is OFF.
IFFFILE : Pfad und Name des Iff-Files.
Default is 'ram:Lupe.iff'
By starting from CLI you can specify these arguments and override the
tooltypes.
"CX_PRIORITY=P/N/K, FAST=F/S/K, MAXSCALEFACTOR=M/N/K, SCALEFACTOR=S/N/K,
WINLEFT=L/N/K, WINTOP=T/N/K, WINWIDTH=W/N/K, WINHEIGHT=H/N/K,
COORDINATES=C/S/K, CROSSHAIR=R/S/K, SETORIGINKEY=O/K, RESETORIGINKEY=K/K,
FIXED=D/S/K, SHOWHIDEKEY=SH/K, ICONIFY=I/S/K, ICONIFYONCLOSE=IOC/S/K,
GRID=G/S/K, SHOWRGB=RGB/S/K, IFFFILE=IF/K"
The values are the same as the tooltypes.
The scalefactor can be set with the proportional gadget nested in the right
windowborder.
The menu:
Jump : Jumps to the next screen.
Jump To Screen : A submenu with the actually opened screens. The window was
opened on the selected screen.
