GetBitmap

public final int GetBitmap(int[] dst,
                           int w,
                           int h,
                           guidodrawdesc desc,
                           guidopaint area,
                           java.awt.Color color)

Draws the score into a bitmap. Actually, draws the score to an offscreen that is next copied to the destination bitmap. It use native system of the device, so it's not implemented if a the GuidoEngine library is build with INDEPENDENSVG option, like in android platform.

Parameters:

dst - the destination bitmap ARGB array

w - the bitmap width

h - the bitmap height

desc - the score drawing descriptor

area - clipping description

color - the color used to draw the score

Returns:

a Guido error code.

guidodrawdesc, guidopaint

Draw

public int Draw(java.awt.Graphics g,
                int w,
                int h,
                guidodrawdesc desc,
                guidopaint area)

Draws the score. Drawing the score should be typically called from the paint method of a Canvas. It use native system of the device, so it's not implemented if a the GuidoEngine library is build with INDEPENDENSVG option.

Parameters:

g - a Graphics

w - the desired drawing width

h - the desired drawing heigth

desc - the score drawing descriptor

area - clipping description

Returns:

a Guido error code.

                guidopaint area,
                java.awt.Color color)

Draws the score. Drawing the score should be typically called from the paint method of a Canvas. It use native system of the device, so it's not implemented if a the GuidoEngine library is build with INDEPENDENSVG option.

Parameters:

                int w,
                int h,
                guidodrawdesc desc,
                guidopaint area,
                java.awt.Color color)

Draws the score. Drawing the score should be typically called from the paint method of a Canvas. It use native system of the device, so it's not implemented if a the GuidoEngine library is build with INDEPENDENSVG option.

Parameters:

g - a Graphics

top - the top coordinate to begin to draw the image

left - the left coordinate to begin to draw the image

w - the desired drawing width

h - the desired drawing height

desc - the score drawing descriptor

area - clipping description

color - the color used to draw the score

Returns:

a Guido error code.
