[OpenJDK 2D-Dev] [11] RFR JDK-5109146: PNGMetadata Background color initialization from standard metadata is incomplete

[Jayathirth D V]

Hello All,

 

Please review the following fix in JDK11 :

 

Bug : https://bugs.openjdk.java.net/browse/JDK-5109146 

Webrev : http://cr.openjdk.java.net/~jdv/5109146/webrev.00/ 

 

Issue: PNGMetadata.mergeStandardTree() function doesn't set proper bKGD 
colortype.

 

Solution: When bKGD R, G, B values are unique we need to store appropriate bKGD 
colortype in metadata.

 

Note : Test case which is present as part of review in JDK-6574555 is only 
updated to handle regression scenario for this bug also. Regression scenario 
between this bug and JDK-6574555 differ only in what type(native/standard) 
metadata we use to merge bKGD RGB values.

 

Thanks,

Jay
