Class AbstractBitmap

java.lang.Object

webplugin.aclib.image.ico.AbstractBitmap

Direct Known Subclasses:

AbstractBitmapIndexed, AbstractBitmapRGB

public abstract class AbstractBitmap
extends Object

Parent class for all icon bitmaps, indexed or RGB.

Why is creation and read() not one thing? Because we might want to create the object, fill it step by step, and then write it.

Field Detail

_descriptor

protected BitmapDescriptor _descriptor

Describes the bitmap.

Constructor Detail

AbstractBitmap

public AbstractBitmap(BitmapDescriptor pDescriptor)

Parameters:

pDescriptor - The image descriptor.

Method Detail

createImageRGB

public abstract BufferedImage createImageRGB()

Create an RGB image rendition of this bitmap.

Returns:

A BufferedImage rendition (RGB) of this bitmap.

read

abstract void read(AbstractDecoder pDec)
            throws IOException

Read bitmap from the decoder into class internal data structures. Implemented by specific Bitmap classes.

Parameters:

pDec - The decoder.

Throws:

IOException

getHeight

protected int getHeight()

The (manipulated height - read on). I found that a) mostly (but not always) the height reported by the header is double the real size, and b) that the descriptor is usually correct.

Returns:

Returns the height.

getWidth

protected int getWidth()

Get the bitmap width.

Returns:

Returns the width.

getColorCount

protected int getColorCount()

getDescriptor

public BitmapDescriptor getDescriptor()

Get the bitmap descriptor.

Returns:

Returns the descriptor.

setDescriptor

void setDescriptor(BitmapDescriptor pDescriptor)

Parameters:

pDescriptor - The descriptor to set.

toString

public String toString()

Simply returns the class name which reflects the bitmap type.

Overrides:

toString in class Object
