Subject [jira] Updated: (HARMONY-3570) [classlib][awt] Png decoder does not work on Linux x86_64
Date Mon, 16 Apr 2007 10:30:15 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-3570?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrey Pavlenko updated HARMONY-3570:
-------------------------------------

    Attachment: HARMONY-3570.patch

I think it's ok to use int in Java code for width and height. According to the libpng spec:

The PNG specification allows the width and height of an image to be as large as 2^31-1 (0x7fffffff),
or about 2.147 billion rows and columns.  Since very  few  applications  really  need  to
 process such large images, we have imposed an arbitrary 1-million limit on rows and columns.

Please try this patch.
