The Default Ink Object
When QuickDraw GX first creates an ink object, that object has default characteristics defined by QuickDraw GX. A default ink object has the following properties:
Transfer modes, matrices, color limits, and flags are described in subsequent sections of this chapter. Color spaces and color components are described in the chapter "Colors and Color-Related Objects" in this book.
- No attributes set.
- An empty tag list.
- An owner count of 1.
- Color space set to
gxRGBSpacewith each color component set to 0, which represents black in this color space.- Transfer mode set to gxCopyMode, with identity transfer mode matrices, color limits of 0 to 0xFFFF, and all flags cleared. Copy mode is the default transfer mode assigned to all color components of an ink object, because it is most common and fastest.
To reset an ink object to its default properties, use the
GXResetInkfunction, described on page 5-60.
