In chapter 6, there's an example called 'TextRendering.java'. |
This class makes use of a class called 'ApplicationFrame'.
I looked in the index and found no reference to this class.
At the beginning of the book, on page 8, I found a description
of this class, and I was able to deduce that the drawing that
took place in the example could also be done in a regular, AWT
frame. I really think that this class, 'ApplicationFrame',
should be included in the index. It seems to turn up in just
about every example. Insert an index entry of
ApplicationFrame, 8

Figure 1-1." It should say "in Figure C-1 (in the color insert)."

Figures 3.5 and 3.7 have the control points labeled as the |
filled squares and the endpoints are the unfilled squares
when in fact the control point should be labeled as the open
squares and the endpoint as the filled squares.

In Figure 3-9, the numbers should run from 0 through 6, NOT 1 |
through 7. Otherwise, the text that begins at the bottom of
page 35 says the exact opposite of what the author intended.

last paragraph |
In the paragraph "Dashes", the description of dash array:
"The even elements of the array (starting at index 0) determine where the line is
visible, while the odd elements determine where it's invisible." is technically
incorrect.
In fact, BasicStroke "cyclic" applies the dash array elements to alternates visible
and invisible.
For example: an array like {10, 20, 30} (odd number of array elements and phase == 0)
will first 10 units visible, then 20 units invisible, then 30 units visible, then 10
units invisible, then 20 units visible, ... etc
As the result shown, because "cyclic" rule, we cannot say the even elements are
always visible and the odd elements are always invisible.
(if the number of dash array is not even)

2nd paragraph; |
The code example:
hints.add(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDERING_ON);
is incorrect.
It can be fixed by changing "add" to "put" and changing
"VALUE_RENDER_ON" to "VALUE_RENDER_QUALITY". The resulting code excerpt
is:
public void paint(Graphics g) {
Graphics2D g2 = (Graphics2D)g;
RenderingHints hints = new RenderingHints(
RenderingHints.KEY_ANTIALIASING,
RenderingHints.VALUE_ANTIALIAS_ON);
hints.put(RenderingHints.KEY_RENDERING,
RenderingHints.VALUE_RENDER_QUALITY);
g2.setRenderingHints(hints);
// ...

reader to "use one of Graphics2D's drawText() methods" to render text.
it should read:

The output on Win32/jdk1.3 and MacOSX/jdk1.3 is:
java.awt.Color[r=255,g=0,b=0] -> 0
java.awt.Color[r=0,g=255,b=0] -> 1
java.awt.Color[r=0,g=0,b=255] -> 2
java.awt.Color[r=64,g=255,b=64] -> 1
java.awt.Color[r=255,g=255,b=0] -> 0
java.awt.Color[r=0,g=255,b=255] -> 1
0 -> unnormalized components 255 0 0
1 -> unnormalized components 0 255 0
2 -> unnormalized components 0 0 255
3 -> unnormalized components 255 255 255
4 -> unnormalized components 0 0 0
The book has extra 255's at the end of the last 5 lines. This is
incorrect.
