Constructor Detail

ImageBitMask

public ImageBitMask(int width,
                    int height)

Initializes a new instance of the ImageBitMask class with the specified width and height.

Parameters:

width - Width of the mask.

height - Height of the mask.

ImageBitMask

public ImageBitMask(RasterImage image)

Initializes a new instance of the ImageBitMask class with the size of the specified existing RasterImage. Specified RasterImage will be stored as source image.

Parameters:

image - Source image.

Method Detail

getSelectionBounds

public Rectangle getSelectionBounds()

Gets the bounds of the selected part of the mask, in pixels.

Returns:

the bounds of the selected part of the mask, in pixels.

get_Item

public boolean get_Item(int x,
                        int y)

Gets the opacity of the specified pixel.

Specified by:

get_Item in class ImageMask

Parameters:

x - The x-coordinate of the pixel.

y - The y-coordinate of the pixel. Value: true if the specified pixel is opaque; otherwise, false.

Returns:

true if the specified pixel is opaque; otherwise, false.

inflate

public ImageMask inflate(int size)

Inflates this mask by the specified amount.

Specified by:

inflate in class ImageMask

Parameters:

size - The amount to inflate this mask.

Returns:

An inflated ImageBitMask as ImageMask.

crop

public ImageMask crop(Rectangle rectangle)

Crops mask with the specified rectangle.

Specified by:

crop in class ImageMask

Parameters:

rectangle - The specified rectangle.

Returns:

A cropped ImageBitMask as ImageMask.

deepClone

public Object deepClone()

Creates a new object that is a copy of the current instance.

Specified by:

deepClone in interface com.aspose.ms.System.ICloneable

Specified by:

deepClone in class ImageMask

Returns:

A new object that is a copy of this instance.

setMaskPixel

public final void setMaskPixel(int x,
                               int y,
