- PURPOSE
- This is the support-library for BlitzBlank-modules. These functions
- handle the communication between BlitzBlank and the blankermodules.
- Also, there are some additional functions, which may be of use for
- some modules.
-
- ALL modules MUST use the following functions:
- - BBL_GetString()
- - BBL_SendMessage()
- - BBL_ModuleRunning()
- - BBL_BlankDone()
-
- Modules, which open their own screen, instead of getting one from
- BlitzBlank (what most modules do), should use the following
- functions in addition:
- - BBL_BlankMouse()
- - BBL_UnBlankMouse()
- - BBL_CloseScreenSafe()
-
- The other functions could be useful for your module. Check them out.

-
- NAME
- BBL_AllocBitMap -- Allocate a bitmap.
-
- SYNOPSIS
- bitmap = BBL_AllocBitMap( width, height, depth, flags)
- D0 D1 D2 D3
-
- struct BitMap *BBL_AllocBitMap( ULONG, ULONG, ULONG, ULONG )
-
- FUNCTION
- Allocates a bitmap with the given width, height, depth and flags.
- This function is V39-aware and will so call V39's AllocBitMap(),
- if available. You will probably need this function in modules
- with doublebuffering or hidden drawing.
-
- INPUTS
- width - Width of the bitmap in pixels.
-
- height - Height of the bitmap in pixels.
-
- depth - Number of planes in the bitmap.
-
- flags - BMF_CLEAR to specify that the allocated raster should be
- filled with color 0.
-
- BMF_DISPLAYABLE to specify that this bitmap data should
- be allocated in such a manner that it can be displayed.
- Displayable data has more severe alignment restrictions
- than non-displayable data in some systems.
-
- BMF_INTERLEAVED tells graphics that you would like your
- bitmap to be allocated with one large chunk of display
- memory for all bitplanes. This minimizes color flashing
- on deep displays. If there is not enough contiguous RAM
- for an interleaved bitmap, graphics.library will fall
- back to a non-interleaved one.
-
- RESULTS
- bitmap - Allocated and initialized bitmap or NULL, if the call failed.

- NAME
- BBL_AllocDBufBitMap -- Allocate a bitmap for double-buffering.
-
- SYNOPSIS
- bitmap = BBL_AllocDBufBitMap( screen )
- A0
-
- struct BitMap *BBL_AllocDBufBitMap( struct Screen * )
-
- FUNCTION
- Allocates a 2nd bitmap for the given screen with the same size,
- depth and attributes (flags). At this time, it just calls
- BBL_AllocBitMap(), but in the future, it may know how to deal
- with graphic-cards.
-
- INPUTS
- screen - An open screen, for which the bitmap is for.
- (It is safe, to pass a NULL here -> nothing will be done)
-
- RESULTS
- bitmap - Allocated and initialized BitMap or NULL, if the call failed.

- NAME
- BBL_AllocRastPort -- Allocate a rastport.
-
- SYNOPSIS
- rastport = BBL_AllocRastPort( width, height, depth, flags )
- D0 D1 D2 D3
-
- struct RastPort *BBL_AllocRastPort( ULONG, ULONG, ULONG, ULONG )
-
- FUNCTION
- Allocates a rastport with the given width, height, depth and flags.
- You will probably need this function in modules with doublebuffering
- or hidden drawing. Actually, this function allocates a rastport and
- then calls BBL_AllocBitMap().
-
- INPUTS
- width - Width of the rastport in pixels.
-
- height - Height of the rastport in pixels.
-
- depth - Number of planes in the rastport.
-
- flags - BMF_CLEAR to specify that the allocated raster should be
- filled with color 0.
-
- BMF_DISPLAYABLE to specify that this bitmap data should
- be allocated in such a manner that it can be displayed.
- Displayable data has more severe alignment restrictions
- than non-displayable data in some systems.
-
- BMF_INTERLEAVED tells graphics that you would like your
- bitmap to be allocated with one large chunk of display
- memory for all bitplanes. This minimizes color flashing
- on deep displays. If there is not enough contiguous RAM
- for an interleaved bitmap, graphics.library will fall
- back to a non-interleaved one.
-
- RESULTS
- rastport - Allocated and initialized RastPort or NULL, if the call failed.

-
- NAME
- BBL_BlankDone -- Tell BlitzBlank that blanking is finished.
-
- SYNOPSIS
- BBL_BlankDone()
-
- void BBL_BlankDone( void )
-
- FUNCTION
- Signals BlitzBlank, that your Module is finished with the
- blank()-function. The module must call it, after its blank()-function
- returned. BlitzBlank will then close the blankscreen (if it opened
- one).

- NAME
- BBL_BlankMouse -- Blank the mouse on your own screen.
-
- SYNOPSIS
- window = BBL_BlankMouse( screen, mode )
- A0 D0
-
- struct Window *BBL_BlankMouse( struct Screen *, UBYTE )
-
- FUNCTION
- Opens a window on the screen at position (0,0).
- The window is borderless. This window will be activated and the
- mousepointer for this window will be made invisible -> The mouse
- is blanked. Keep the result of this function for passing it
- to BBL_UnBlankMouse() later. If you get a screen from BlitzBlank,
- you will never need this function, because BlitzBlank will then
- do the mouseblanking for you. Normally, you will use mode 0,
- but if you want to have a RastPort with clipping to draw in, you
- could use mode 1 for a fullscreen-window and use this window's
- RastPort to draw in, instead of the screen's RastPort.
-
- INPUTS
- screen - Pointer to an open screen.
- (It is safe, to pass a NULL here -> nothing will be done)
-
- mode - 0 for small window (1x1), 1 for fullsize-window.
-
- RESULTS
- window - Keep this for use with BBL_UnBlankMouse().

- NAME
- BBL_CloneFirstScreen -- Clone the first screen.
-
- SYNOPSIS
- screen = BBL_CloneFirstScreen( moredepth, flags )
- D0 D1
-
- struct Screen *BBL_CloneFirstScreen( UWORD, ULONG )
-
- FUNCTION
- Clones the first screen. That means it opens a screen with the same
- dimensions, same colors and same contents. Normally, you won't need
- this function, because you can get a cloned first screen by BlitzBlank
- with the flag BBF_CloneScreen in BB_Message/flags. You only need this
- function, if you decide at run-time, if you want a custom screen or a
- cloned screen.
-
- INPUTS
- moredepth - If you want a deeper screen than the first screen then set
- this to the number of additional bitplanes.
-
- flags - BBF_Interleaved for an interleaved screen.
-
- RESULTS
- screen - Cloned first screen or NULL.

-
- NAME
- BBL_CloseScreenSafe -- Close a screen safely.
-
- SYNOPSIS
- BBL_CloseScreenSafe( screen )
- A0
-
- void BBL_CloseScreenSafe( struct Screen * )
-
- FUNCTION
- This function calls intuition's CloseScreen(). But if it can't close
- the screen (because there are windows left open on it), it waits
- until it really can close the screen. If you get the screen from
- BlitzBlank, you will never need this function, because BlitzBlank
- closes the screen for you (safely). But if you open the blankscreen
- yourself, you should use this function to close it (after closing
- all your own windows, of course), because there may be "visitor"-
- windows from some nasty programs (eg ARQ, TrapDoor) on your
- screen.
-
- INPUTS
- screen - Pointer to an open screen.
- (It is safe, to pass a NULL here -> nothing will be done)

- SYNOPSIS
- success = BBL_CopyOriginalColors( screen )
- A0
-
- BOOL BBL_CopyOriginalColors( struct Screen * )
-
- FUNCTION
- This function copies the palette of the original first screen to the
- screen. It is only useful for screen-cloning modules, which want
- to open their blankscreen on their own.
- If you get your screen from BlitzBlank, you will never need this
- function.
- This function is V39-aware and knows how to copy colors with
- 256 levels of R, G, B.
-
- INPUTS
- screen - Pointer to an open screen.
- (It is safe, to pass a NULL here -> nothing will be done)

- NAME
- BBL_InitDBuf -- Initialize the library's double-buffering.
-
- SYNOPSIS
- handle = BBL_InitDBuf( screen, bitmap )
- A0 A1
-
- ULONG BBL_InitDBuf( struct Screen *, struct BitMap * )
-
- FUNCTION
- Initializes the library's double-buffering functions. Before you
- can use BBL_ShowBitMap(), you MUST call this function. It will then
- decide, which method of double-buffering will be used by
- BBL_ShowBitMap(). If the system is running at least V39 and the
- 2 bitmaps (screen->RastPort.BitMap and bitmap) have the same
- flags (BOTH interleaved ot BOTH non-interleaved), then the
- double-buffering will be much faster. So, only request
- an interleaved screen (and an interleaved bitmap) if you really
- need them, because it is not sure, that the OS is able to
- give them to you. If not, you could end up with an interleaved
- screen and a non-interleaved bitmap. That would lead to
- the slower double-buffering method. For an example of
- how to use the library's double-buffering, look at the docs to
- BBL_ShowBitMap().
-
- INPUTS
- screen - The screen, which will be double-buffered.
- (It is safe, to pass a NULL here -> nothing will be done)
-
- bitmap - The 2nd BitMap, which will be used for double-buffering.
- It should be allocated with BBL_AllocDBufBitMap().
- (It is safe, to pass a NULL here -> nothing will be done)
-
- RESULTS
- handle - An internal handle, which must be passed also to BBL_ShowBitMap()
- and BBL_EndDBuf() or 0, if the call failed.

- A0 D0 D1
-
- void BBL_RainbowPalette( struct Screen *, ULONG, ULONG )
-
- FUNCTION
- Creates a rainbow-like palette for the given screen. Be careful: YOU
- are responsible, that lowreg and highreg really exist in the ViewPort
- of the screen. Also, highreg must be greater or equal lowreg.
- Example (creates a complete rainbow palette, except color 0):

-
- SYNOPSIS
- BBL_ShowBitMap( screen, bitmap, handle )
- A0 A1 A2
-
- void BBL_ShowBitMap( struct Screen *, struct BitMap *, ULONG )
-
- FUNCTION
- Shows the bitmap at the next vertical blank. You must have called
- BBL_InitDBuf() before you can use this function. Currently, it
- knows two methods of double-buffering. Is uses them depending
- on the OS-version and the flags of the screen and the bitmap
- (see doc to BBL_InitDBuf()). The function itself waits for the
- next vertical blank after changing the bitmap, so you don't have
- to call WaitTOF() yourself.
- NOTE: This function doesn't change the screen->RastPort.BitMap
- pointer, so if you want to draw to the 2nd bitmap via a
- rastport, you have to set this pointer to the drawing bitmap
- by yourself.
- Here is an example, of how to do double-buffering with this library
- (without error-checking):
-
- struct Screen *myscreen;
- struct BitMap *bm[2];
- int actual=1;
- ULONG dbufhandle;
-
- bm[0]=myscreen->RastPort.BitMap;
- bm[1]=BBL_AllocDBufBitMap (myscreen);
-
- dbufhandle=BBL_InitDBuf (myscreen,bm[1]);
- myscreen->RastPort.BitMap=bm[actual];
-
- loop
- {
- /* draw into bm[actual] or &myscreen->RastPort */
-
- BBL_ShowBitMap (myscreen,bm[actual],dbufhandle);
- actual=1-actual;
- myscreen->RastPort.BitMap=bm[actual];
- }
- BBL_ShowBitMap (myscreen,bm[0],dbufhandle);
- myscreen->RastPort.BitMap=bm[0];
- BBL_EndDBuf (dbufhandle);
- BBL_FreeBitMap (bm[1]);
-
- INPUTS
- screen - The screen, where the bitmap will be shown.
-
- bitmap - The bitmap, that will be shown. You should allocate it with
- BBL_AllocDBufBitMap().
-
- handle - An internal handle, as returned by BBL_InitDBuf().
- (It is safe, to pass a 0 here -> nothing will be done)
