[Moved] CJPEGExifDecoder

[venugopalck]

Hi,

I am using exif to you create a thumbnail image..... when i modified code and try compiling it shows error undeclared variable CJPEGExifDecoder and same error for many other exif variables..... i tried in blogs and included .h and .lib files mentioned but those are not available in my SDK....

I am compiling for 3rd Edition FP1 category

Does anybody knows how to resolve this problem?

Awaiting for your response.

Thanks,
Venu.

you could mayb check SDK docs, it says: "This item is not part of the S60 3rd Edition SDK for Symbian OS, Supporting Feature Pack 1, for C++." for the CJPEGExifDecoder API.

Thanks for your quick reply,

then whats the solution to resolve that error? should i need to do some changes before compiling?

Thats means we cannot use this utility for 3rd edition FP1 and below?

[symbianyucca]

if the API is not included in the SDK, then it can not be used within the SDK.

Thanks,

Could you please check the link below i have raised another question regarding thumbnail,

Hi,

You can load an image file to a CFbsBitmap object and at the same time resize it (to a thumbnail...)

TFrameInfo bmpInfo=iDecoder->FrameInfo();
delete iBitmap;
iBitmap = NULL;
iBitmap=new(ELeave) CFbsBitmap;
//TInt err = iBitmap->Create(bmpInfo.iOverallSizeInPixels,bmpInfo.iFrameDisplayMode); // no we don't want to load the full size image
TSize size(bmpInfo.iOverallSizeInPixels.iWidth/2, bmpInfo.iOverallSizeInPixels.iHeight/2);
TInt err = iBitmap->Create(size, bmpInfo.iFrameDisplayMode); // load the image and at the same time resize it to a quarter of the original frame size.
User::LeaveIfError(err);
iDecoder->Convert(&iStatus,*iBitmap);
SetActive();

and some of the image files may contain thumbnails, for example generally the JPEG files captured by the built-in Camera app contain QQVGA (160x120) EXIF thumbnail. As decoding the thumbnail is faster than decoding the main image, you can always try the CImageDecoder::SetImageTypeL(CImageDecoder::EImageTypeThumbnail) before turning to decoding the main image.
