Constructor Detail

BmpImage

public BmpImage(BmpStreamHeader bmpStreamHeader)

Initializes a new instance of the BmpImage class.

Parameters:

bmpStreamHeader - The bmp stream header.

BmpImage

public BmpImage(BmpStreamHeader bmpStreamHeader,
                IColorPalette colorPalette,
                boolean useCompactPalette)

Initializes a new instance of the BmpImage class.

Parameters:

bmpStreamHeader - The bmp stream header.

colorPalette - The color palette.

useCompactPalette - if set to true compact palette is used.

Method Detail

getBitsPerPixel

public int getBitsPerPixel()

Gets the image bits per pixel count.

Value: The image bits per pixel count.

Specified by:

getBitsPerPixel in class Image

getHeight

public int getHeight()

Gets the image height.

Value: The image height.

Specified by:

getHeight in interface IObjectWithBounds

Specified by:

getHeight in class Image

getHorizontalResolution

public double getHorizontalResolution()

Gets the horizontal resolution, in pixels per inch, of this RasterImage.

Value: The horizontal resolution.

Note by default this value is always 96 since different platforms cannot return the screen resolution. You may consider using the SetResolution method for updating both resolution values in single call.

Overrides:

getHorizontalResolution in class RasterImage

getImageLoaderDescriptorName

public java.lang.String getImageLoaderDescriptorName()

Gets the name of the image loader descriptor.

Value: The name of the image loader descriptor.

This value is used later for proper image deserialization, thus specify valid registered descriptor here. During deserialization each descriptor type name is validated against this value.

Specified by:

getImageLoaderDescriptorName in class Image

getVerticalResolution

public double getVerticalResolution()

Gets the vertical resolution, in pixels per inch, of this RasterImage.

Value: The vertical resolution.

Note by default this value is always 96 since different platforms cannot return the screen resolution. You may consider using the SetResolution method for updating both resolution values in single call.

Overrides:

getVerticalResolution in class RasterImage

getWidth

public int getWidth()

Gets the image width.

Value: The image width.

Specified by:

getWidth in interface IObjectWithBounds

Specified by:

getWidth in class Image

onCompactPaletteUsageChanged

protected void onCompactPaletteUsageChanged()

Called when compact palette usage is changed.

Overrides:

onCompactPaletteUsageChanged in class Image

onPaletteChanged

protected void onPaletteChanged(IColorPalette oldPalette,
                                IColorPalette newPalette)

Called when palette is changed.

Overrides:

onPaletteChanged in class Image

Parameters:

oldPalette - The old palette.

newPalette - The new palette.

onPaletteChanging

protected void onPaletteChanging(IColorPalette oldPalette,
                                 IColorPalette newPalette)

Called when palette is changing.

Overrides:

onPaletteChanging in class Image

Parameters:

oldPalette - The old palette.

newPalette - The new palette.

resize

public void resize(int newWidth,
                   int newHeight,
                   int resizeType)

Resizes the image.

Overrides:

resize in class RasterImage

Parameters:

newWidth - The new width.

newHeight - The new height.

resizeType - The resize type.

rotateFlip

public void rotateFlip(int rotateFlipType)

Rotates, flips, or rotates and flips the image.

Overrides:

rotateFlip in class RasterImage

Parameters:

rotateFlipType - Type of the rotate flip.

setHorizontalResolution

public void setHorizontalResolution(double value)

Sets the horizontal resolution, in pixels per inch, of this RasterImage.

Value: The horizontal resolution.

Note by default this value is always 96 since different platforms cannot return the screen resolution. You may consider using the SetResolution method for updating both resolution values in single call.

Overrides:

setHorizontalResolution in class RasterImage

setResolution

public void setResolution(double dpiX,
                          double dpiY)

Sets the resolution for this RasterImage.

Overrides:

setResolution in class RasterImage

Parameters:

dpiX - The horizontal resolution, in dots per inch, of the RasterImage.

dpiY - The vertical resolution, in dots per inch, of the RasterImage.

setVerticalResolution

public void setVerticalResolution(double value)

Sets the vertical resolution, in pixels per inch, of this RasterImage.

Value: The vertical resolution.

Note by default this value is always 96 since different platforms cannot return the screen resolution. You may consider using the SetResolution method for updating both resolution values in single call.

Overrides:

setVerticalResolution in class RasterImage
