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
