viewdhr -- view a double hi-res picture (EXTERNAL) [v1.1] Written by Jeff Ding
|
|
|
|
syntax: viewdhr <pathname> [-f] [-r]
|
|
|
|
ex: viewdhr /picture.disk/pic.1
|
|
viewdhr /picture.disk/pic.1 -f
|
|
viewdhr /picture.disk/pic=
|
|
|
|
'viewdhr' displays a double hi-res picture on the screen without leaving
|
|
the Davex command shell. Wildcards are accepted in the pathname.Once the
|
|
picture is displayed, any key will exit. Ctrl-C will abort wildcard
|
|
expansions. 'viewdhr' will not work on a II+ or 64k //e because they do
|
|
not have the auxiliary memory needed to display double hi-res pictures.
|
|
This program will work on a //c, //e compatible with an extended 80 column
|
|
card, and the //gs.
|
|
|
|
In order for 'viewdhr' to work you have to uninstall the ram driver in
|
|
slot 3 drive 2. To do that you have to use the 'ram3' external command.
|
|
The following options are available:
|
|
|
|
-f: force load -- This option will force the program to load the
|
|
picture regardless of the status of the ram drive. Use this
|
|
option with caution as it will destroy any files that might
|
|
be stored in that memory
|
|
|
|
-r: reverse pages -- This option will load the picture in reversed
|
|
format. Normally the first half of the file is loaded into the
|
|
auxiliary memory and the second half into the main memory. Using
|
|
this option will switch the main and auxiliary pages in memory.
|
|
|
|
'viewdhr' makes sure the filetype is BIN or FOT and the auxtype is set
|
|
to $2000. It then loads the file and displays it on the screen. It
|
|
will not load the picture if the length is less than $2001 bytes.
