Font represents fonts in a device independent manner; after being |
|
50 |
created using 'Font family:family face:face style:style size:size', |
|
51 |
the returned font is not associated to a specific device. |
|
157 | 52 |
(therefore, those fonts can be used to draw on any GC) |
0 | 53 |
|
46 | 54 |
To get a device font, any font can be sent the message |
55 |
'aFont on:aDevice' which returns an instance of Font which is |
|
56 |
associated to a device (it returns the receiver, if that is already |
|
57 |
associated to that device). |
|
0 | 58 |
|
46 | 59 |
For proper operation, each graphics operation working with fonts |
60 |
must get a device font before doing the draw. |
|
61 |
Most draw methods in DeviceDrawable do that automatically for you, |
|
157 | 62 |
before doing the draw; so you do not have to care. |
46 | 63 |
|
81 | 64 |
However, some operations require explicit conversion to a device font |
7346 | 65 |
before being allowed. For example, a query for a font's height (in device |
81 | 66 |
units) can only be done if the font being asked is associated to |
67 |
a device (which should be clear, since a 'courier-roman-12' font may |
|
68 |
have a different number of pixels on a 75dpi vs. a 120dpi display. And |
|
564 | 69 |
a totally different number of device units on a 600dpi laser printer. |
81 | 70 |
Thus, to query a font for its height (or ascent, or descent, or width), |
71 |
use something like: |
|
72 |
||
564 | 73 |
myFont := Font family:'courier' ... size:12. |
74 |
... |
|
81 | 75 |
|
564 | 76 |
'want to know its height on the Display' |
81 | 77 |
|
564 | 78 |
h := (myFont on:Display) height. |
81 | 79 |
|
564 | 80 |
'want to know its height on a printer' |
81 | 81 |
|
564 | 82 |
h := (myFont on:aPrinter) height. |
2545 | 83 |
|
84 |
there are alternative shortcuts for these operations: |
|
85 |
||
86 |
h := myFont heightOn:Display. |
|
87 |
h := myFont heightOn:Printer. |
|
88 |
||
89 |
or: |
|
90 |
||
91 |
a := myFont ascentOn:Display. |
|
92 |
||
81 | 93 |
Keep in mind, that each device is free to think in whatever units it |
94 |
likes - a display may return units of pixels, a postscript printer may |
|
95 |
think in (fractions of) inches, a dot matrix printer may think in dots. |
|
96 |
Also, notice that currently only graphic displays are really supported; |
|
97 |
printer devices are being developped and may or may not be in the current |
|
98 |
system. |
|
99 |
||
564 | 100 |
If a font cannot be represented on a device, a replacement |
46 | 101 |
font is chosen and kept in the replacementFont instance variable. |
564 | 102 |
This is done to preserve the original font information, in case the image |
103 |
is restarted later on another display which has that font available. |
