C# Class SwfDotNet.IO.Tags.Types.BitmapFill

Two type of bitmap fill are supported:

• Clipped: If the area to be filled is larger than the image then the colour at the edge of the image is used to fill the remainder of the shape.
• Tiled: If the area to be filled is larger than the image then the image is tiled across the area to be filled.

When an image is loaded its width and height default to twips rather than pixels. An image 300 x 200 pixels will be displayed as 300 x 200 twips (15 x 10 pixels). Scaling the image by 20 (20 twips = 1 pixel) using the Matrix object will restore it to its original size.

The image is drawn with the top left corner placed at the origin (0, 0) of the shape being filled. Depending on how the shape is drawn the coordinate transform may also need to specify a translation to place the image at the desired location.

When To Use ?

In addition to filling shapes with images that represent textures or complex fill patterns the BitmapFill class is required to display any image in a Flash file - image can only be displayed in Flash inside a shape definition. The classes that define images only contain the image data, not how it is displayed. To simply display an image, the selected line style of a shape may be set to zero so that the image is displayed without a border.
