Thomas Neidhart resolved IMAGING-104.
-------------------------------------
Resolution: Cannot Reproduce
Fix Version/s: 1.0
> ByteSourceInputStream not starting at byte 0
> --------------------------------------------
>
> Key: IMAGING-104
> 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
> Fix For: 1.0
>
>
> 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.
