+.Sh DESCRIPTION
+.Nm Libvgl
+is a library that enables the programmer access to the graphics
+modes supported by the console driver (syscons). The library takes care of
+programming the actual video hardware, and provides a number of simple
+functions to do various graphic operations. There is also support for a
+mouse via the standard mouse system in
+.Fx ,
+see
+.Xr mouse 4 ,
+including the ability to transparently have a mouse pointer superimposed on
+the graphic image currently being worked on.
+The library takes care of screen switching by storing the current image in
+memory before switching to another virtual console, and restoring when the
+user switches back. This allows several graphic applications at once, but
+on different virtual consoles.
+
+Below is a short description of the various functions:
+.Pp
+.Fn VGLInit
+initialize the library and set up the graphic mode
+.Em mode .
+.Pp
+.Fn VGLEnd
+terminate graphic mode, and restore the screenmode that was active before
+.Fn VGLInit
+was called.
+.Pp
+.Fn VGLCheckSwitch
+if the program goes into longer periods of processing without doing
+any graphics output, calling this function occasionally will allow
+the system to switch screens.
+.Pp
+.Fn VGLTextSetFontFile
+instruct the char/string functions to use the font in file
+.Em filename
+instead of the builtin font.
+.Pp
+.Fn VGLKeyboardInit
+set up the keyboard in the ``raw'' I/O mode and
+specify the key code to be used.
+.Em code
+must be
+.Em VGL_XLATEKEYS ,
+.Em VGL_CODEKEYS ,
+or
+.Em VGL_RAWKEYS .
+When
+.Em VGL_XLATEKEYS
+is specified, the keyboard translate the raw keyboard scan code into
+a character code.
+If
+.Em VGL_RAWKEYS
+is used, the raw keyboard scan code is read as is.
+.Em VGL_CODEKEYS
+is the intermediate key code; each key is assigned a unique code whereas
+more than one raw scan code may be generated when a key is pressed.
+.Pp
+.Fn VGLKeyboardEnd
+when you have finished using the keyboard, call this function.
+.Pp
+.Fn VGLKeyboardGetCh
+read one byte from the keyboard. As the keyboard I/O is in the ``raw''
+input mode, the function will not block even if there is no input data,
+and returns 0.
+.Pp
+.Fn VGLMouseInit
+initialize the mouse. The optional on-screen mouse pointer is shown if the
+argument is
+.Em VGL_MOUSESHOW .
+.Pp
+.Fn VGLMouseMode
+either shows the mouse pointer if the argument is
+.Em VGL_MOUSESHOW ,
+or hides the mouse pointer if the argument is
+.Em VGL_MOUSEHIDE .
+.Pp
+.Fn VGLMouseStatus
+returns the current mouse pointer coordinates and button state in
+.Em x , y ,
+buttons. The return value reflects if the mouse pointer
+is currently shown on screen or not.
+.Pp
+.Fn VGLMouseSetImage
+with this function it is possible to change the image of the mouse pointer
+on screen.
+.Pp
+.Fn VGLMouseSetStdImage
+this function restores the mouse pointer to the standard arrow.
+.Pp
+.Fn VGLGetXY
+retrieves the color of the pixel located at
+.Em x , y ,
+coordinates of the
+.Em object
+argument, and returns it as a byte value.
+.Pp
+.Fn VGLSetXY
+sets the color of the pixel located at
+.Em x , y ,
+coordinates of the
+.Em object
+argument to
+.Em color
+byte value.
+.Pp
+.Fn VGLLine
+draw a line from
+.Em x1 , y1
+to
+.Em x2 , y2
+in color
+.Em color .
+.Pp
+.Fn VGLBox
+draw a box with upper left hand corner at
+.Em x1 , y1
+and lower right hand corner at
+.Em x2 , y2
+in color
+.Em color .
+.Pp
+.Fn VGLFilledBox
+draw a filled (solid) box with upper left hand corner at
+.Em x1 , y1
+and lower right hand corner at
+.Em x2 , y2
+in color
+.Em color .
+.Pp
+.Fn VGLEllipse
+draw an ellipse centered at
+.Em xc , yc
+make it
+.Em a
+pixels wide, and
+.Em b
+pixels high in color
+.Em color .
+.Pp
+.Fn VGLFilledEllipse
+draw a filled (solid) ellipse centered at
+.Em xc , yc
+make it
+.Em a
+pixels wide, and
+.Em b
+pixels high in color
+.Em color .
+.Pp
+.Fn VGLBitmapCreate
+create a bitmap object and initialize it with the specified
+values and bit data.
+.Em type
+must be
+.Em MEMBUF
+for the in-memory bitmap.
+.Em bits
+may be NULL so that bitmap data may be associated later.
+.Pp
+There also is a macro,
+.Fn VGLBITMAP_INITIALIZER "type" "xsize" "ysize" "bits"
+to initialize a statically declared bitmap object.
+.Pp
+.Fn VGLBitmapDestroy
+free the bitmap data and the bitmap object.
+.Pp
+.Fn VGLBitmapAllocateBits
+allocate a bit data buffer for the specified object.
+.Pp
+.Fn VGLBitmapCopy
+copy a rectangle of pixels from bitmap
+.Em src
+upper left hand corner at
+.Em srcx , srcy
+to bitmap
+.Em dst
+at
+.Em dstx , dsty
+of the size
+.Em width , height .
+.Pp
+.Fn VGLBitmapPutChar
+write the character
+.Em ch
+at position
+.Em x , y
+in foreground color
+.Em fgcol .
+If
+.Em fill
+is != 0, use the color
+.Em bgcol
+as background otherwise the background is transparent.
+The character is drawn in the direction specified by the argument
+.Em dir .
+.Pp
+.Fn VGLBitmapString
+write the string
+.Em str
+at position
+.Em x , y
+in foreground color
+.Em fgcol .
+If
+.Em fill
+is != 0, use the color
+.Em bgcol
+as background otherwise the background is transparent.
+The string is drawn in the direction specified by the argument
+.Em dir .
+.Pp
+.Fn VGLClear
+clears the entire bitmap to color
+.Em color .
+.Pp
+.Fn VGLSetPalette
+this function sets the palette used, the arguments
+.Em red , green , blue
+should point to byte arrays of 256 positions each.
+.Pp
+.Fn VGLSetPaletteIndex
+set the palette index
+.Em color
+to the specified RGB value.
+.Pp
+.Fn VGLSetBorder
+set the border color to color
+.Em color .
+.Pp
+.Fn VGLSetVScreenSize
+change the virtual screen size of the display. Note that this
+function must be called when our vty is in the foreground.
+And
+.Em object
+must be
+.Em VGLDisplay .
+Passing a in-memory bitmap to this function results in error.
+.Pp
+The desired virtual screen width may not be achievable because
+of the video card hardware. In such case the video driver (and
+underlaying video BIOS) may choose the next largest values.
+Always examine
+.Em object->VXsize
+and
+.Em VYsize
+after calling this function, in order to see how the virtual screen
+is actually set up.
+.Pp
+In order to set up the largest possible virtual screen, you may
+call this function with arbitrary large values.
+.Pp
+.Dl VGLSetVScreenSize(10000, 10000);
+.Pp
+.Fn VGLPanSreen
+change the origin of the displayed screen in the virtual screen.
+Note that this function must be called when our vty is in the
+foreground.
+.Em object
+must be
+.Em VGLDisplay .
+Passing a in-memory bitmap to this function results in error.
+.Pp
+.Fn VGLBlankDisplay
+blank the display if the argment
+.Em blank
+!= 0. This can be done to shut off the screen during display updates that
+the user should first see when it's done.
