构造器详细资料

ICOImage

public ICOImage(java.awt.image.BufferedImage image,
        InfoHeader infoHeader,
        IconEntry iconEntry)

Creates a new instance of ICOImage

参数:

image - the BufferedImage decoded from the source ICO image

infoHeader - the BMP InfoHeader structure for the BMP encoded ICO image

iconEntry - the IconEntry structure describing the ICO image

方法详细资料

getIconEntry

public IconEntry getIconEntry()

The IconEntry associated with this ICOImage, which provides information about the image format and encoding.

返回:

the IconEntry structure

setIconEntry

public void setIconEntry(IconEntry iconEntry)

Sets the IconEntry associated with this ICOImage.

参数:

iconEntry - the new IconEntry structure to set

isPngCompressed

public boolean isPngCompressed()

Specifies whether the encoded image is PNG compressed.

返回:

true if the encoded image is PNG compressed, false if it is plain BMP encoded

setPngCompressed

public void setPngCompressed(boolean pngCompressed)

Sets whether the encoded image is PNG compressed.

参数:

pngCompressed - true if the encoded image is PNG compressed, false if it is plain BMP encoded

getInfoHeader

public InfoHeader getInfoHeader()

The InfoHeader structure representing the encoded ICO image.

覆盖:

getInfoHeader 在类中 BMPImage

返回:

the InfoHeader structure, or null if there is no InfoHeader structure, which is possible for PNG compressed icons.

getIconIndex

public int getIconIndex()

The zero-based index for this ICOImage in the source ICO file or resource.

返回:

the index in the source, or -1 if it is unknown.

setIconIndex

public void setIconIndex(int iconIndex)

Sets the icon index, which is zero-based.

参数:

iconIndex - the zero-based icon index, or -1 if unknown.

getWidth

public int getWidth()

The width of the ICO image in pixels.

覆盖:

getWidth 在类中 BMPImage

返回:

the width of the ICO image, or -1 if unknown

the height of the ICO image, or -1 if unknown.

从以下版本开始:

0.7alpha2

getColourDepth

public int getColourDepth()

The colour depth of the ICO image (bits per pixel).

覆盖:

getColourDepth 在类中 BMPImage

the colour depth, or -1 if unknown.

从以下版本开始:

0.7alpha2

getColourCount

public int getColourCount()

The number of possible colours for the ICO image.

覆盖:

getColourCount 在类中 BMPImage

从以下版本开始:

0.7alpha2

isIndexed

public boolean isIndexed()

Specifies whether this ICO image is indexed, that is, the encoded bitmap uses a colour table. If getColourDepth() returns -1, the return value has no meaning.

覆盖:

isIndexed 在类中 BMPImage

返回:

true if indexed, false if not.
