Method Detail

copyBufferedImage

public BufferedImage copyBufferedImage(BufferedImage img)

Description copied from interface: GraphicsUtils

Produces a copy of a buffered image with the same graphic content (pixel color)

Specified by:

copyBufferedImage in interface GraphicsUtils

Parameters:

img - image to be copied

Returns:

new instance of a BufferedImage (editable) with same size, type and graphic content.

createBufferedImage

public BufferedImage createBufferedImage(int w,
                                         int h,
                                         int type)

Description copied from interface: GraphicsUtils

Create a buffered Image of the given size and type. In this context, buffered image means editable image (admits setRGB etc)

Specified by:

createBufferedImage in interface GraphicsUtils

Parameters:

w - width in pixels of the requested image

h - height in pixels of the requested image

type - image type (refers to bands, etc. see Image

Returns:

a buffered (editable) image of the desired size and type

createPrintAttributes

public PrintAttributes createPrintAttributes()

Description copied from interface: GraphicsUtils

Creates an object that implements the PrintAttributes interface with default/trivial values.

Specified by:

createPrintAttributes in interface GraphicsUtils

Returns:

an object that implements the PrintAttributes interface with default/trivial values.

deriveFont

public Font deriveFont(Font srcfont,
                       float newheight)

Description copied from interface: GraphicsUtils

Returns an istance of Font which is the same as the one provided except for the size.

Specified by:

deriveFont in interface GraphicsUtils

Parameters:

srcfont - provided font to be used as model

newheight - height in pixels of the new fonr

Returns:

the new font, same properties as the provided font, but different size

getScreenDPI

public int getScreenDPI()

Tries to use DPI value from gvSIG preferences. If this does not exist, gets value from Java Toolkit.

Specified by:

getScreenDPI in interface GraphicsUtils

Returns:

number of pixels per inch in the current screen

translate

public void translate(Graphics2D g,
                      double x,
                      double y)

Description copied from interface: GraphicsUtils

Adds a translation operation to the Graphics2D object's transformation matrix.

Specified by:

translate in interface GraphicsUtils

Parameters:

g - Object whose transformation matrix has to be modified

x - horizontal offset of the translation

y - vertical offset of the translation

setRenderingHintsForDrawing

public void setRenderingHintsForDrawing(Graphics2D g)

Description copied from interface: GraphicsUtils

Sets the rendering hints to the Graphics2D object in a way that is suitable for drawing.

Specified by:

setRenderingHintsForDrawing in interface GraphicsUtils

Parameters:

g - the Graphics2D object whose rendering hints have to be set for drawing

setRenderingHintsForPrinting

public void setRenderingHintsForPrinting(Graphics2D g)

Description copied from interface: GraphicsUtils

Sets the rendering hints to the Graphics2D object in a way that is suitable for printing.

Specified by:

setRenderingHintsForPrinting in interface GraphicsUtils

Parameters:

g - the Graphics2D object whose rendering hints have to be set for printing
