Backwards compatibility broken: Why was Color made final
After upgrading to FX8, the framework I have been developing since the early access release of JavaFX three years ago is now broken. My framework has some really cool features for working with color, which relies on our own class PaletteColor which extends javafx.scene.paint.Color. Why would you, after three years, make the Color class final, thereby breaking backwards compatibility? I would really like to know the thoughts behind that decision. Yours Randahl

Re: Backwards compatibility broken: Why was Color made final
Hi Randhal, The reasons are captured in the description of RT-31746 https://javafx-jira.kenai.com/browse/RT-31746 which was the JIRA used to track this change in FX 8. The fact that Color wasn't final was an unfortunate oversight in FX 2. -- Kevin Randahl Fink Isaksen wrote: After upgrading to FX8, the framework I have been developing since the early access release of JavaFX three years ago is now broken.

EasyBind: custom bindings made easy (with lambdas)
Hi all, I just released EasyBind (http://www.fxmisc.org/easybind/), a tiny library with several factory methods to create bindings using lambdas. The most prominent feature is probably the type-safe select binding based on this feature request for JavaFX 9: https://javafx-jira.kenai.com/browse/RT-35923. Regards, Tomas

Re: Congratulations
So yes, a big THANK YOU to Richard and his team and everyone at Oracle and all the other individuals and 3rd parties who have contributed to getting JavaFX (and Java) to where it is today. You guys/gals should be really proud :-) I agree, congrats to all the folks inside and outside Oracle that have been making tremendous contributions to JavaFX! A special thanks to Steve for really pushing OpenJFX as a real open source project with an open development process. We really want to work with the community on this project on an equal footing. We’ve had tons of valuable contributions in the form of bug fixes, blog posts, technical discussions, and patches. Keep up the great work! 8u20 has a big pile of bug fixes, so please do kick the tires on that one. Lots of great work going on in terms of Accessibility right now, also embedded work and as always performance work. Scene Builder is healthy and active, we’d love to see it embedded in all the IDEs and direct contributions from the community to Scene Builder would be fantastic. A big thanks to the porters brining JavaFX to Android/iOS and other platforms! Looking forward to 8u20 and Java 9! Richard

Re: Opacity in Image.getPixelReader.getColor()
Kevin and Jasper hit the nail on the head (Jasper's comment that the
words are usually associated with particular ranges is mostly true

If there is part of the documentation here that could be made clearer,
let us know...

Opacity and alpha are mostly used interchangeably. Whether the range is
expressed as a normalized value [0.0,1.0] or an 8-bit pixel value
[0,255], the meaning is the same. A value of 0 means that the color is
completely transparent. When using the default SRC_OVER blend equation,
a pixel with this color will have no effect. A value of 1.0 (if using a
normalized value) or 255 (if using an 8-bit integer value) means that
the color is fully opaque. When using the default SRC_OVER blend
equation, a pixel with this color will overwrite whatever is underneath it.
Perhaps Tom is thinking of transparency which, if we were to have such
an attribute, would be defined as (1.0-opacity).

Hi,
Maybe I'm completely wrong but to me it looks like the opacity I get
from Image.getPixelReader.getColor() is wrong.
If not mistaken the relation between alpha and opacity is expressed
with:
opacity = (255 - alpha) / 255.0
which means:
opacity 0 = alpha 255
opacity 1 = alpha 0
Running the following programm on a gif
public class OpacityBug extends Application {
@Override
public void start(Stage primaryStage) throws Exception {
Image image = new
Image(getClass().getResourceAsStream(methpri_obj.gif));
int width = (int) image.getWidth();
int height = (int) image.getHeight();
PixelReader reader = image.getPixelReader();
for (int x = width - 1; x = 0; x--) {
for (int y = height - 1; y = 0; y--) {
int argb = reader.getArgb(x, y);
int alphaArgb = (argb 24) 0xFF;
Color color = reader.getColor(x, y);
double opacity = color.getOpacity();
System.err.println(x+,+y + = alpha: +
alphaArgb + op: + opacity + op-alpha: +
opacityToAlpha(opacity) + color: + color);
}
}
}
private static int opacityToAlpha(double opacity) {
return (int)Math.roundopacity * 255.0) - 255) * -1));
}
public static void main(String[] args) {
Application.launch(args);
}
}
produces and output like:
15,15 = alpha: 0 op: 0.0 op-alpha: 255 color: 0x
which to my understanding is wrong. The argb value is correct (if
compared to the image because the pixel at 15,15 is fully transparent)
but then the the opacity should be 1.0 but is the opposite.
Looking at the code in Image I see:
@Override
public Color getColor(int x, int y) {
int argb = getArgb(x, y);
int a = argb 24;
int r = (argb 16) 0xff;
int g = (argb 8) 0xff;
int b = (argb ) 0xff;
return Color.rgb(r, g, b, a / 255.0);
}
which means that:
a) my formula from the above is wrong
b) or there's the bug because it should be
return Color.rgb(r, g, b, (255 - a) / 255.0);
May I also suggest to add get a
- Color.argb(int r,int g,int b,int alpha)
maybe it is just me but I'm so much more used to alpha than opacity that
I always have to look it up when i need it.
Tom
