[OpenJDK 2D-Dev] Review request for JDK-7182758: BMPMetadata returns invalid PhysicalPixelSpacing

[Jayathirth D V]

Hello All,

 

Please review following fix in jdk9:

 

Bug : https://bugs.openjdk.java.net/browse/JDK-7182758

 

Webrev : http://cr.openjdk.java.net/~rchamyal/jay/7182758/webrev.00/

 

Bug : BMPMetadata returns invalid PhysicalPixelSpacing

 

Root cause : Whenever XPixelsPerMter or YPixelsPerMeter is more than value 1 in 
BMP header. Horizontal & Vertical Physical pixel spacing were returned as zero.

                          In getStandardDimensionNode() method of 
BMPMetadata.java we are dividing 1 by XPixelsPerMter/ YPixelsPerMter. When

                          XPixelsPerMter/ YPixelsPerMter is more than 1. 
Resulted value is stored without decimal part, which resulted in zero.

 

Solution : Made changes to how Horizontal & Vertical Physical pixel spacing is 
calculated so that decimal value is not truncated.

 

Thanks,

Jay
