----------------------------------------

Hi Thomas,

Thanks for testing this, but it is solved. I must have made an typing 
error somewhere. It's working now.

Regards,
Marc

>                 URL: https://issues.apache.org/jira/browse/IMAGING-104
>             Project: Commons Imaging
>          Issue Type: Bug
>          Components: Format: JPEG
>    Affects Versions: 0.97
>            Reporter: Marc Campforts
>
> Following code results in a  
> org.apache.sanselan.ImageReadException: Not a Valid JPEG File: doesn't begin 
> with 0xffd8
> File file = new File(image.jpg);
> InputStream is = new FileInputStream(file);
> JpegImageParser parser = new JpegImageParser();
> ByteSource byteSource = new ByteSourceInputStream(is, "image.jpg");
> ArrayList<?> segments = parser.readSegments(byteSource, new int[] {0xffee}, 
> true);
> But when I use the File instead of the InputStream:
> File file = new File(image.jpg);
> JpegImageParser parser = new JpegImageParser();
> ByteSource byteSource = new ByteSourceFile(file);
> ArrayList<?> segments = parser.readSegments(byteSource, new int[] {0xffee}, 
> true);
> it works.
> When I look into the exception, the process starts to read from byte 1024 
> instead of byte 0 when checking the filetype.
