EVALUATION This is the bug in the regression test. The responsibility of this bug depend on environement. Actually, the regression test is ok if the color quality is 24 bit and more. But this bug is reproducible if the depth is 16 bit and less. In the test we use Robot.getRixelColor() and compare the resulted value with the template values (Color.red, ...). But this values is acceptable only if the depth is high. It's possible to complete this test by means of the calculating of the template values at the beggining of the test. Namely, we place canvas on frame and do setBackround/getPixelColor for the interested colors (that we using in the test). ###@###.### 2005-07-19 13:40:19 GMT ###@###.### 2005-07-19 15:19:50 GMT
