BBCtoBMP
--------
Syntax: BBCtoBMP <bbc screen> -m <mode> <bitmap> -s -v

Runs on BBC, Master, RISC OS, DOS and Windows.

Converts a BBC graphics screen image (MODEs 0 to 6) to a Windows bitmap
file. Will also read a compressed screen image and palette information
stored in load and execution addresses by *ScrSave.

If no palette information is available then the default palette for the
specified screen mode is used.

If the -s small switch is given then small screen modes (MODE 4 to 6) are
output as 320x256 pixels images instead of 640x256 pixel images.

If the -v verbose switch is given a countdown of converted pixel lines is
displayed.

On DOS/Windows is a '.inf' file is present, then the load and execution
addresses are read from it. The '.inf' file will also be read on BBC/RISC
OS if the source file's load and execution addresses are both zero.


BMPtoBBC
--------
Syntax: BMPtoBBC <bitmap> <bbc screen> -m <mode> -i -v

Runs on BBC, Master, RISC OS, DOS and Windows.

Converts a Windows bitmap file to a BBC graphics screen image (MODEs 0 to
6). Will also store palette information in load and execution addresses
readable with *ScrLoad. If the bitmap is not 640 pixels wide,
unpredicatable results will occur.

On DOS/Windows a '.inf' file is created containing the load and execution
addresses containing the palette information. A '.inf' file will also be
created on BBC/RISC OS if the -i switch is used.

If the -v verbose switch is given a countdown of converted pixel lines is
displayed.

If the source bitmap is a dump of a MODE 0 to 2 screen, then BMPtoBBC can
work this out, and the <mode> parameter can be omitted. Otherwise, the mode
must be specified.


*BMPSave
--------
Syntax: *BMPSave <filename>

Saves the currently displayed screen as a bitmap.


*BMPLoad
--------
Syntax: *BMPLoad <filename>

Changes screen mode and loads the specified bitmap to the screen.
