I provide the common protocol for a graphicsContext which is associated with a particular |
|
6292 | 42 |
device (i.e. Bitmaps, Pixmaps, RootWindow and Windows in Xs world, but also postscript |
732 | 43 |
printer pages or fax pages). |
44 |
||
45 |
My instance variables are mainly caching device-related stuff (such as font- and color-Ids) |
|
46 |
to avoid needless message traffic. This class is abstract, no direct instances of it |
|
47 |
exist in the system. |
|
48 |
All real work is done by my device, which is accessed via the device instance variable. |
|
6292 | 49 |
Most drawing requests are simply forwarded to it, others are simulated by using more basic |
732 | 50 |
drawing functions (see GraphicsContext drawing vs. basic drawing category). |
51 |
||
6292 | 52 |
The added variables foreground/background are the drawing colors actually |
732 | 53 |
used; these are the real (i.e. non dithered) colors supported by the device. |
6292 | 54 |
Direct access to fg/bg is discouraged, since in the future, these may be |
55 |
totally replaced by paint/bgPaint |
|
56 |
(there are some operations and special cases, for which a direct access to |
|
732 | 57 |
fg/bg makes sense) |
