    Question How to capture QVGA size bitmap image (CBitmapScaler::Scale() too slow)

    Hi, all.

    Now, I'm developing camera application for 6680.
    I capture bitmap image from front camera and scaling to QVGA size.

    But, Scaling speed too slow ! (about 3 sec.)

    scaling code is following:

    Code:
    CFbsBitmap* iBitmap; // captured image
    CBitmapScaler* iScaler; // convert image size to QVGA
    ConstructL()
    Code:
    iScaler = CBitmapScaler::NewL();
    ImageReady()
    Code:
    // scaling from VGA to QVGA
    iScaler->Scale(&iStatus, *iBitmap, TSize(320,240));
    SetActive();
    6680 front camera caputure VGA or 160x120(QQVGA?) image only.
    How to capture QVGA size bitmap image or fast scaling code.
    plz...

    Regards,

    Thumbs up Re: How to capture QVGA size bitmap image (CBitmapScaler::Scale() too slow)

    I solved this problem by writing my own bilinear scaler method.
