Well it is confusing since in particular this exact change is in both
webrevs :-
http://cr.openjdk.java.net/~psadhukhan/8162796/webrev.01/src/java.desktop/macosx/native/libawt_lwawt/awt/QuartzSurfaceData.m.sdiff.html
One thing that I think seems less ideal about this fix, at least for
the Gradient case is that it is creating an image which shows pixelisation
effects when I zoom in using Preview ..
I don't think the previous code showed those effects so it may be you
want a hybrid, using the original code when you can.
That probably is not an issue for TexturePaint ..

No, this webrev supports LinearGradient/RadialGradient for all 3
options. The fix seems to be almost same as in TexturePaint but in a
different else block in OSXSurfaceData.java.

Leaving aside the tests, the webrev here looks to be the one proposed
for the TexturePaint bug. Did you get things mixed up ?

Hi Phil,
I have modified the webrev to support REFLECT and REPEAT albeit via
raster path and not via Quartz api, as Quartz cannot handle
REPEAT/REFLECT.
http://cr.openjdk.java.net/~psadhukhan/8162796/webrev.01/
Have tested with different fractions, stops, color.

Hi,
LinearGradientPaint has three options as to how it is extended
beyond the end point
https://docs.oracle.com/javase/8/docs/api/java/awt/MultipleGradientPaint.CycleMethod.html
So far as I can see this code (and perhaps quartz) can only handle
NO_CYCLE ..
If REFLECT or REPEAT are specified and Quartz can't handle it we
will need to
fall back to the raster path.
I think it would be helpful to extend the test with examples that
use these and
also more than just the two colours .. add a variant that tries
more like 4 ...

Hi All,
Please review a fix for jdk9 where it is seen that
LinearGradientPaint is not getting printed on osx.
The below webrev is only for LinearGradientPaint
and RadialGradientPaint will be handled separately.
Bug: https://bugs.openjdk.java.net/browse/JDK-8162796
webrev: http://cr.openjdk.java.net/~psadhukhan/8162796/webrev.00/
Issue was LinearGradientPaint is not handled in osx from jdk7
onwards. It handles simple GradientPaint.
Code is added as per
https://developer.apple.com/library/content/documentation/GraphicsImaging/Conceptual/drawingwithquartz2d/dq_shadings/dq_shadings.html#//apple_ref/doc/uid/TP30001066-CH207-TPXREF101
to use "CGGradientRef" quartz datatype to support
LinearGradientPaint.
CGGradientRef is used compared to CGShadingRef because it is
mentioned in CGGradientRef, i is "Easy to define more than two
locations and colors." as we set 2 or more colors and 2 or more
fractions in LinearGradientPaint.

Prasanta
