I don't understand the TransparencyWin code that much, but it strikes me as odd that resulting pixels would be affected by translation differently depending on what kind of layer mode was being used. This behavior doesn't happen for KeepTransform, for instance. 137792 2012-04-18 15:58:41 -0700 2012-04-18 15:58:41 -0700 Failing unit test bug-84294-20120418155835.patch text/plain 2073 enne U3VidmVyc2lvbiBSZXZpc2lvbjogMTE0NTMzCmRpZmYgLS1naXQgYS9Tb3VyY2UvV2ViS2l0L2No cm9taXVtL3Rlc3RzL1RyYW5zcGFyZW5jeVdpblRlc3QuY3BwIGIvU291cmNlL1dlYktpdC9jaHJv bWl1bS90ZXN0cy9UcmFuc3BhcmVuY3lXaW5UZXN0LmNwcAppbmRleCA1MDUyYmIxNjYzZTQzNjVk ZDE5NTEwZTY2OGEzZjQ3YmI1YTQ5MzhmLi4zMDdkZWVmN2Q4Yzg0NDljOTcwNTU0OTFiMGViMjEy YmUxZTMzNTMwIDEwMDY0NAotLS0gYS9Tb3VyY2UvV2ViS2l0L2Nocm9taXVtL3Rlc3RzL1RyYW5z cGFyZW5jeVdpblRlc3QuY3BwCisrKyBiL1NvdXJjZS9XZWJLaXQvY2hyb21pdW0vdGVzdHMvVHJh bnNwYXJlbmN5V2luVGVzdC5jcHAKQEAgLTUyMiw2ICs1MjIsNTggQEAgVEVTVChUcmFuc3BhcmVu Y3lXaW4sIERJU0FCTEVEX1RyYW5zbGF0ZVNjYWxlT3BhcXVlQ29tcG9zaXRlTGF5ZXIpCiAgICAg fQogfQogCitzdGF0aWMgdm9pZCB0ZXN0TGF5ZXJTY2FsZVRyYW5zZm9ybShUcmFuc3BhcmVuY3lX aW46OkxheWVyTW9kZSBsYXllck1vZGUpCit7CisgICAgLy8gRmlsbCB3aXRoIHdoaXRlLgorICAg IE93blB0cjxJbWFnZUJ1ZmZlcj4gc3JjKEltYWdlQnVmZmVyOjpjcmVhdGUoSW50U2l6ZSgxNiwg MTYpLCAxLCBDb2xvclNwYWNlRGV2aWNlUkdCKSk7CisgICAgQ29sb3Igd2hpdGUoMHhGRkZGRkZG Rik7CisgICAgRmxvYXRSZWN0IGZ1bGxSZWN0KDAsIDAsIDE2LCAxNik7CisgICAgc3JjLT5jb250 ZXh0KCktPmZpbGxSZWN0KGZ1bGxSZWN0LCB3aGl0ZSwgQ29sb3JTcGFjZURldmljZVJHQik7CisK KyAgICBzcmMtPmNvbnRleHQoKS0+c2F2ZSgpOworCisgICAgLy8gU2NhbGUgYnkgMnguCisgICAg QWZmaW5lVHJhbnNmb3JtIHNjYWxlOworICAgIHNjYWxlLnNjYWxlKDIuMCk7CisgICAgc3JjLT5j b250ZXh0KCktPmNvbmNhdENUTShzY2FsZSk7CisKKyAgICAvLyBUcmFuc2xhdGUgYnkgMXB4ICgy cHggaW4gc2NhbGVkIHNwYWNlKQorICAgIHNyYy0+Y29udGV4dCgpLT50cmFuc2xhdGUoMCwgMSk7 CisKKyAgICBDb2xvciBncmVlbigweEZGMDBGRjAwKTsKKyAgICB7CisgICAgICAgIFRyYW5zcGFy ZW5jeVdpbiBoZWxwZXI7CisgICAgICAgIGhlbHBlci5pbml0KHNyYy0+Y29udGV4dCgpLAorICAg ICAgICAgICAgICAgICAgICBsYXllck1vZGUsCisgICAgICAgICAgICAgICAgICAgIFRyYW5zcGFy ZW5jeVdpbjo6U2NhbGVUcmFuc2Zvcm0sCisgICAgICAgICAgICAgICAgICAgIEludFJlY3QoMCwg MCwgMTYsIDE2KSk7CisKKyAgICAgICAgRmxvYXRSZWN0IGdyZWVuUmVjdCg2LCA4LCAxLCAxKTsK KyAgICAgICAgaGVscGVyLmNvbnRleHQoKS0+ZmlsbFJlY3QoZ3JlZW5SZWN0LCBncmVlbiwgQ29s b3JTcGFjZURldmljZVJHQik7CisgICAgICAgIGhlbHBlci5jb21wb3NpdGUoKTsKKyAgICB9CisK KyAgICBzcmMtPmNvbnRleHQoKS0+cmVzdG9yZSgpOworCisgICAgLy8gVmVyaWZ5IGdyZWVuIHBp eGVsIGdvdCBkcmF3biBpbiBjbGlwIHJlY3QgYW5kIHJlZCBwaXhlbCBnb3QgY2xpcHBlZC4KKyAg ICBFWFBFQ1RfRVEoZ3JlZW4sIGdldFBpeGVsQXQoc3JjLT5jb250ZXh0KCksIDYsIDgpKTsgLy8g RklYTUU6IGF0IDYsIDEwIGlmIG5vdCBOb0xheWVyCit9CisKK1RFU1QoVHJhbnNwYXJlbmN5V2lu LCBTY2FsZVRyYW5zZm9ybU5vTGF5ZXIpCit7CisgICAgdGVzdExheWVyU2NhbGVUcmFuc2Zvcm0o VHJhbnNwYXJlbmN5V2luOjpOb0xheWVyKTsKK30KKworVEVTVChUcmFuc3BhcmVuY3lXaW4sIFNj YWxlVHJhbnNmb3JtT3BhcXVlQ29tcG9zaXRlTGF5ZXIpCit7CisgICAgdGVzdExheWVyU2NhbGVU cmFuc2Zvcm0oVHJhbnNwYXJlbmN5V2luOjpPcGFxdWVDb21wb3NpdGVMYXllcik7Cit9CisKK1RF U1QoVHJhbnNwYXJlbmN5V2luLCBTY2FsZVRyYW5zZm9ybVdoaXRlTGF5ZXIpCit7CisgICAgdGVz dExheWVyU2NhbGVUcmFuc2Zvcm0oVHJhbnNwYXJlbmN5V2luOjpXaGl0ZUxheWVyKTsKK30KKwog Ly8gVGVzdHMgc2NhbGUgbW9kZSB3aXRoIG5vIGFkZGl0aW9uYWwgY29weS4KIFRFU1QoVHJhbnNw YXJlbmN5V2luLCBTY2FsZSkKIHsK
