Description Thomas Küstermann CLA 2011-01-14 13:41:30 EST 
Build Identifier: v20100915-1750

We're actually faced with lots of 'Invalid byte 1 of 1-byte UTF-8 sequence' exceptions in our server logs because of the background image handling in HTMLReportEmitter.handleStyleImage( String uri, boolean isBackground ).

The responsible code fragment tries to convert a non SVG image to JPEG using Batik. This fails with the mentioned error message (printed out by Batik) and fills up our log files. This is a cosmetic problem but very annoying.

Reproducible: Always

Steps to Reproduce:
1. Create a report with a background image
2. Use HTMLRenderOption to render the report

Hi Xiaoying Gu,

Could you please point us to the changes which were made to fix this issue and if the same changes can be made in 2.6.2 for our internal use? The server logs are currently filled up with the error message and is a big problem.

Thanks & regards,
Madhav

This change is made in HTMLReportEmitter.java:

Please find the method: 
public String handleStyleImage( String uri, boolean isBackground )

and replace the line:
byte[] buffer = SvgFile.transSvgToArray( uri );

to 

byte[] buffer = EmitterUtil.getImageData( uri );

then it should work.
