Method Detail

createShapeForImage

public static DefineShapeTag createShapeForImage(DefineImage image,
                                 BitmapGraphicNode node)

Creates a rectangle for the given width and height as a DefineShape. The shape is painted with a bitmap FillStyle with the given DefineBits tag.

Parameters:

image - The DefineBits tag encoding the image.

node - The BitmapGraphicNode.

Returns:

A rectangle of given width and height as a DefineShape with a bitmap fill.

bitmapImageNeedsClipping

public static boolean bitmapImageNeedsClipping(DefineImage defImage,
                               BitmapGraphicNode node)

Determines whether the bitmap image should be clipped.

Parameters:

defImage - The tag encoding the image.

node - The BitmapGraphicNode.

Returns:

boolean if bitmap should be clipped.

bitmapFillModeIsRepeat

public static boolean bitmapFillModeIsRepeat(BitmapFillNode node)

Determines whether the bitmap fill mode is repeat.

Parameters:

node - The BitmapFillNode.

Returns:

boolean if bitmap should repeat.

isBitmapFillWithClip

public static boolean isBitmapFillWithClip(IFillNode fill)

createDefineBits

public static DefineImage createDefineBits(InputStream in,
                           String mimeType)
