> off.

> Key: IMAGING-264
> URL: https://issues.apache.org/jira/browse/IMAGING-264
> Project: Commons Imaging
> Issue Type: Bug
> Components: Format: BMP
> Affects Versions: 1.0-alpha2
> Reporter: Ram
> Assignee: Bruno P. Kinoshita
> Priority: Minor
> Fix For: 1.0-alpha3
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> In BMPImageParser class, the values are typecasted to int before rounding off
> so output varies(other parsers has this logic correct).
> int physicalWidthDpi = (int)((double)bhi.hResolution * 0.0254D);
> int physicalHeightDpi = (int)((double)bhi.vResolution * 0.0254D);
>
> Expected :
> int physicalWidthDpi = (int)*Math.round*((double)bhi.hResolution * 0.0254D);
> int physicalHeightDpi = (int)*Math.round*((double)bhi.vResolution * 0.0254D);
