Instructions for BackLoad V1.0


Background.

After  some  drewling  over my friends A500+ with its wonderful WorkBench I
started  to code this rather useless utility.  Well it might be useless but
it sure can be lovely to look upon, or is it Cindy Crawford thats lovely.


Using from WorkBench.

Just  dubbleclick  the  icon  to  start  BackLoad.   When started you see 6
gadgets with the functions described below.

The filename:  Just enter the name of the raw format file you want to load.
remember  to have the file in the same size as the coords in the upper left
corner shows, and to keep in mind how many bitplanes you want to use.

Load Pic: Clicking this gadget executes the picture with its preferences.

1  WB  Bpl:   If you are short on chipmem click here to use only 1 bitplane
for the normal WorkBench screen.  Gadget is highlighted when activated.

2  Bpl  Pic:   Click here to toggle 1 or 2 bitplane(s) use for the picture.
The startup-default is 2 bitplanes.

Click  to  load  colors:   If  you have a file called "filename.col" (where
filename  is the filename descibed before) containing a colortable, and you
want to use them instead of the default, activate this gadget.

Smooth:  Toggle this gadget to change the colors to a "look through" image.


To  turn  off  the  BackLoad  simply  start  the  program again and it will
automatically  turn  itself  off.  Please take notice that if you are using
ShadowWindows,  or likevice programs, these will stop working while running
BackLoad and vice versa.


Starting from CLI.

When  starting from CLI or SHELL you can enter the filename and choose from
the following options (handy in startup-sequences):

-w Load with 1 WorkBench color. Default: 3 colors

-b Load with 1 color picture.	Default: 3 colors

-s Make "look through" effect.	Default: picture behind all.

-c Load colortable with file.	Default: no spec. colortable.

Notice  that  option c has higher priority than s, so you can't have an own
colormap with the "look through" effect unless you make one yourself.

Example: SYS:> BackLoad dh1:Cindy.raw -s


ColorTable.

To make an own colortable just make an ASCII file named piturename.col and
type  in  the  colors  of the registers.  Seperate each color with a blank,
comma or an EOL. (Any sign is legal but you must make one.)

3xfff - Make colorreg 3 white.
^ ^
| |
|	Colorvalue in HEX (only 3 digits)
  Colorregister that you want to change (0-f)

Example:
0x000 4xfff 8xf0f cx888 or

0x000
4xfff
8xf0f
cx888

to change register 0, 4, 8, and c (12).

You dont have to type in all colorregisters, the ones you dont type in will
get  the  same colors as if the option hasn't been choosen.  So you can for
ex.  use the Smooth option and just change one or two colors.


Tips.

If  you  are  very  short on chipmem click for 1 WB Bpl and 1 Bpl Pic, this
allocates  only  48  bytes  extra  memory  (for  the  viewport).  This will
probably not look verry good but it sure doesn't eat up your chipmem.  When
unloading  and  1  plane  WorkBench  screen  you have to activate each open
window  to  get  back  all  colors  (bug  in  the v1.2 and v1.3 kickstart).
BackLoad will run on all kickstart-versions over v1.1
