.Sh NAME
.Nm vgl
.Nd Video Graphics Library functions
.Sh SYNOPSIS
.Fd #include <vgl.h>
.Sh DESCRIPTION
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 FreeBSD, see
.Fn moused
, including the ability to transparantly have a mousepointer superimposed on
the graphic image currently being worked on.
The library takes care of screenswitching by storing the current image in
memory before swithing 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:
.Sh AUTHOR
.An Søren Schmidt (sos@FreeBSD.org)
.Sh FUNCTIONS
.Ft int
.Fn VGLInit "int mode"
Initialize the library and set up the graphic mode
.Em mode
.Ft void
.Fn VGLEnd "void"
Terminate graphic mode, and restore the screenmode that was active before
.Fn VGLInit
was called.
.Ft void
.Fn VGLCheckSwitch "void"
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.
.Ft int
.Fn VGLTextSetFontFile "char *filename"
Instruct the char/string functions to use the font in file
.Em filename
instead of the buildin font.
.Ft int
.Fn VGLMouseInit "int mode"
Initialize the mouse. The optional onscreen mousepointer is shown if the
argument is
.Em VGL_SHOWMOUSE
.Ft void
.Fn VGLMouseMode "int mode"
Either shows the mousepointer if the argument is
.Em VGL_SHOWMOUSE
, or hide the mousepointer if the argument is
.Em VGL_HIDEMOUSE
.Ft int
.Fn VGLMouseStatus "int *x" "int *y" "char *buttons"
Returns the current mousepointer coordiantes and button state in
.Em x, y, buttons. The return value reflects if the mousepointer
is currently shown on screen or not.
.Ft void
.Fn VGLMouseSetImage "VGLBitmap *AndMask" "VGLBitmap *OrMask"
With this function it is possible to change the image of the mousepointer
on screen.
.Ft void
.Fn VGLMouseSetStdImage "void"
This function restores the mousepointer to the standard arrow.
.Ft void
.Fn VGLLine "VGLBitmap *object" "int x1" "int y1" "int x2" "int y2" "byte color"
Draw a line from
.Em x1, y1
to
.Em x2, y2
in color
.Em color
.Ft void
.Fn VGLBox "VGLBitmap *object" "int x1" "int y1" "int x2" "int y2" "byte color"
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
.Ft void
.Fn VGLFilledBox "VGLBitmap *object" "int x1" "int y1" "int x2" "int y2" "byte color"
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
.Ft void
.Fn VGLEllipse "VGLBitmap *object" "int xc" "int yc" "int a" "int b" "byte color"
Draw an ellipse centered at
.Em xc, yc
make it
.Em a
pixels wide, and
.Em b
pixels high in color
.Em color
.Ft void
.Fn VGLFilledEllipse "VGLBitmap *object" "int xc" "int yc" "int a" "int b" "byte color"
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
.Ft int
.Fn VGLBitmapCopy "VGLBitmap *src" "int srcx" "int srcy" "VGLBitmap *dst" "int dstx" "int dsty" "int width" "int hight"
Copy a rectangle of pixels from bitmap
.Em src
upper lefthand corner at
.Em srcx, srcy
to bitmap
.Em dst
at
.Em dstx, dsty
of the size
.Em width, hight
.Ft void
.Fn VGLBitmapPutChar "VGLBitmap *Object" "int x" "int y" "byte ch" "byte fgcol" "byte bgcol" "int fill" "int dir"
Write the character
.Em ch
at position
.Em x, y
in foregroundcolor
.Em fgcol.
If
.Em fill
is != 0, use the color
.Em bgcol
as background otherwise the background is transparant.
The character is drawn in the direction specified by the argument
.Em dir
.Ft void
.Fn VGLBitmapString "VGLBitmap *Object" "int x" "int y" "char *str" "byte fgcol" "byte bgcol" "int fill" "int dir"
Write the string
.Em str
at position
.Em x, y
in foregroundcolor
.Em fgcol.
If
.Em fill
is != 0, use the color
.Em bgcol
as background otherwise the background is transparant.
The string is drawn in the direction specified by the argument
.Em dir
.Ft void
.Fn VGLClear "VGLBitmap *object" "byte color"
Clears the entire bitmap to color
.Em color
.Ft void
.Fn VGLSetPalette "byte *red" "byte *green" "byte *blue"
This function sets the palette used, the arguments
.Em red, green, blue
should point to byte arrays of 256 positions each.
.Ft void
.Fn VGLSetPaletteIndex "byte color" "byte red" "byte green" "byte blue"
Set the palette index
.Em color
to the specified RGB value.
.Ft void
.Fn VGLSetBorder "byte color"
Set the bordercolor to color
.Em color
.Ft void
.Fn VGLBlankDisplay "int blank"
Blank the display if the argment
.Em blank
!= 0. This can be done to shut off the screen during diplay updates that
the use hould first see when its done.
