2D image attributes

The TGrafBundle class described in Chapter 7 has functions that are specific to 2-D image graphics. These functions are described in this chapter and include image pattern paints, dithering, transfer modes, and image sampling as shown in Figure 112.


Fill transfer modes: Algorithms that determine the resulting fill color of a graphic drawn into an image when pixels of one color overlay pixels of another color.

Frame transfer modes: Algorithms that determine the resulting frame color of a graphic drawn into an image when pixels of one color overlay pixels of another color.

Image transfer modes: Algorithms that determine the resulting color of the image when pixels of one color overlay pixels of another color.

Image Sampling: Investigating the status of an image prior to drawing it when the image is enlarged (interpolated) creating pixel gaps or shrunk (decimated) compressing the pixel information.
