Hint | Key | Value | Supported for EA? | Status |
Rendering Hint | KEY_RENDERING | VALUE_RENDER_DEFAULT | Yes | Done |
VALUE_RENDER_SPEED | No | test/jdk/java/awt/MultipleGradientPaint/MultiGradientTest.java passes for OGL and Metal | ||
VALUE_RENDER_QUALITY | No | |||
Antialiasing | KEY_ANTIALIASING | VALUE_ANTIALIAS_DEFAULT | Yes | Done |
VALUE_ANTIALIAS_OFF | Yes | Done | ||
VALUE_ANTIALIAS_ON | Yes | Done. Test passed - jdk/sun/java2d/pipe/Test7027667.java java/awt/geom/Line2D/AALineTest.java Also verified using J2DDemo Some tests fail due to pixel accuracy tolerance. Also, some some combination with AA does not work. Being worked upon separately. | ||

Dithering | KEY_DITHERING | VALUE_DITHER_DEFAULT | Yes | Dither option not present in Font2D, J2DDemo |
VALUE_DITHER_DISABLE | Yes | Dither option not present in Font2D, J2DDemo | ||
VALUE_DITHER_ENABLE | Yes | Dither option not present in Font2D, J2DDemo Test sun/java2d/marlin/OpenJDKFillBug uses this hint and test passes with metal pipeline | ||
Interpolation | KEY_INTERPOLATION | VALUE_INTERPOLATION_NEAREST_NEIGHBOR | Yes | test/jdk/sun/java2d/pipe/InterpolationQualityTest.java This test passes for - Nearest Neighbor interpolation for both OGL and Metal. This test fails for - bilinear and bicubic interpolation - for both OGL and Metal. It is a test issue and will be addressed in JDK-8242562 |
VALUE_INTERPOLATION_BILINEAR | Yes | test/jdk/sun/java2d/SunGraphics2D/DrawImageBilinear.java OGL = passed, metal = passed | ||
VALUE_INTERPOLATION_BICUBIC | No | This was decided to be a non-blocker for EA - and will be worked upon separately - JDK-8242351 test/jdk/sun/java2d/pipe/InterpolationQualityTest.java OGL = failed, metal = failed | ||
Alpha interpolation | KEY_ALPHA_INTERPOLATION | VALUE_ALPHA_INTERPOLATION_DEFAULT | Yes | Works - tested by setting this value on a sample program. Test sun/java2d/marlin/OpenJDKFillBug passes with Metal |
VALUE_ALPHA_INTERPOLATION_SPEED | No | |||
VALUE_ALPHA_INTERPOLATION_QUALITY | No | |||
Color Rendering | KEY_COLOR_RENDERING | VALUE_COLOR_RENDER_DEFAULT | Yes | Works - tested by setting this value on a sample program. Test sun/java2d/marlin/OpenJDKFillBug.java passes with Metal |
VALUE_COLOR_RENDER_SPEED | No | |||
VALUE_COLOR_RENDER_QUALITY | No | |||
Stroke Normalization control | KEY_STROKE_CONTROL | VALUE_STROKE_DEFAULT | Yes | Works - tested by setting this value on a sample program. |
VALUE_STROKE_NORMALIZE | No | Test test/jdk/sun/java2d/marlin/FlipBitTest.java passes with Metal | ||
VALUE_STROKE_PURE | No | |||
Image Scaling Hint | KEY_RESOLUTION_VARIANT | VALUE_RESOLUTION_VARIANT_DEFAULT | Yes | Works -Jtreg test passes test/jdk/java/awt/image/multiresolution/MultiResolutionRenderingHintsTest.java test/jdk/java/awt/image/MultiResolutionImageTest.java |
VALUE_RESOLUTION_VARIANT_BASE | No | |||
VALUE_RESOLUTION_VARIANT_SIZE_FIT | No | |||
VALUE_RESOLUTION_VARIANT_DPI_FIT | No | |||
KEY_TEXT_ANTIALIAS_LCD_CONTRAST (used private in sun.awt.SunHints) Actual hints to be used is KEY_TEXT_LCD_CONTRAST which is used in Font2D | INTKEY_AATEXT_LCD_CONTRAST | No | LCD Contrast value present in Font2D but since surface seems to be not opaque, even if antialiasing hints LCD_HBGR, LCD_HRGB, are used, the glyphs are rendered via Grayscale so LCD contrast is noop Standalone test written to use this hint is passing the contrast value in the hint to LCD text rendering test/jdk/javax/swing/UIDefaults/6302464/bug6302464.java passes with Metal |
