I have a buffer containing JPEG image data. I need to display this

CGDataProviderRef ref = CGDataProviderCreateWithFilename([appFile
UTF8String]);
CGImageRef imgRef =
CGImageCreateWithJPEGDataProvider
(ref,NULL,YES,kCGRenderingIntentSaturation);
UIImage *theImage = [[UIImage alloc] initWithCGImage:imgRef];
Then displaying the image.
For some images I get the images but for some I get the JPEG Image
corrupt
error message.
When I test the same data with Windows application it is able to
display the
image without any error.
Is my conversion from JPEG buffer to UIImage file appropriate or am I
missing out some thing?
Wouldn't:
UIImage *theImage = [[UIImage alloc]
initWithData:theJPEGDataBufferInMemory];
Be simpler and more effective?
That being said, your code looks correct. Can you give us the exact
error message you get?
