Hi, I get the following errors while displaying the JPEG buffered image.
<Error>: Corrupt JPEG data: 584 extraneous bytes before marker 0xc0 <Error>: Quantization table 0x00 was not defined <Error>: Corrupt JPEG data: 446 extraneous bytes before marker 0xdb <Error>: Bogus marker length <Error>: CGImageCreate: invalid image size: 0 x 0. What can be the cause for this error? Any ideas?
